Hypertension Food List
You've heard the term high blood pressure many times. But do you know what it really is And how does it start For reasons that aren't yet clear, the body system that regulates blood flow malfunctions. Blood pressure is the force of blood against artery walls. It's normal for blood pressure to rise and fall during the day. High blood pressure, or hypertension, means consistently higher-than-normal pressure on blood vessel walls. It happens over time as blood gets pushed with more tension through arterioles, or small blood vessels, that become stiff and constricted. High blood pressure also damages artery walls and speeds
Typically, a resting blood pressure greater than 140 90 (read as 140 over 90 ) is regarded as high blood pressure or hypertension. Here, 140 is the systolic blood pressure (measured in millimeters of mercury) or the pressure in large arteries when the heart contracts. In contrast, the 90 refers to diastolic blood pressure or the pressure in large arteries when the heart relaxes. Many physicians consider blood pressure measures under 120 80 to be healthier. That means that a systolic of 120 or higher but below 140 and a diastolic of 80 or higher but below 90 mmHg is considered borderline high blood pressure.
Obesity is associated with the development of hypertension. In many obese people, reductions in blood pressure go hand in hand with reductions in body fat. In addition, if exercise is incorporated into the weight-reduction program, blood pressure is reduced beyond that which can be accounted for by weight loss alone. Stress reduction has also been shown to lower elevated blood pressure significantly. Furthermore, individual diet components such as high-fat and high-saturated-fat foods as well as high-sodium foods have been associated with the development of hypertension. The relationship between diets high in sodium and hypertension does not seem to exist in everyone and will be realized in only about 10 percent of people with high blood pressure. These people are sometimes labeled salt sensitive. This means that their blood pressure can be reduced by following a low-sodium diet (2 grams of sodium day or less). Finally, smoking and or chronic and excessive alcohol consumption is also...
When your heart beats, it pumps blood into your arteries and creates a pressure within them. High blood pressure (also known as hypertension) occurs when too much pressure is placed on the walls of the arteries. This can occ if there is an increase in blood volume or the blood vessels themselves constrict or narrow. Hypertension is the medical term for sustained high blood pressure. It has nothing to do with being tense, nervous, or hyperactive.
High blood pressure is a complex problem, and in most cases its causes are still unknown. Only about 5 to 10 percent of cases can be attributed to known health problems, such as kidney disease. Yet health experts can identify people with increased risk. Family history of high blood pressure There's a genetic tendency for high blood pressure. If there's been a woman under age sixty-five or a man under age fifty-five related to you in your family with hypertension or heart disease, your chances are higher. Race African Americans have higher average blood pressure levels and tend to be more sodium-sensitive than European Americans. Typically African Americans develop hypertension earlier. As a result, they're at greater risk for kidney disease as hypertension progresses and for death from strokes and heart disease. Some Asians also are at greater risk. Overweight Extra body fat, especially around the waist and midriff, increases the risk for high blood pressure. Excessive weight puts...
In 1997, when researchers at Johns Hopkins analyzed the results of more than 30 studies dealing with high blood pressure, they found that people taking daily supplements of 2,500 mg (2.5 grams) of potassium were likely to have blood pressure several points lower than people not taking the supplements. Ask your doctor about this one, and remember Food is also a good source of potassium. One whole banana has up to 470 milligrams of potassium, one cup of dates 1,160 milligrams, and one cup of raisins 1,239 milligrams.

Most of the risk factors for primary hypertension are preventable, and lifestyle modification may prevent as well as treat the condition. Secondary hypertension can be managed by treating the underlying cause. Individuals in the high normal and stage 1 hypertension categories should attempt to lower blood pressure through diet and lifestyle changes before going on a regimen of medications. Recommendations include Onusko, E. (2003). Diagnosing Secondary Hypertension. American Family Physician 67 67-74. Also available from
Many prescription and over-the-counter drugs can cause or exacerbate hypertension. For example, corticosteroids and immunosuppressive drugs increase blood pressure in most solid-organ transplant recipients. Medication taken for pain and inflammation such as nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase-2 (COX-2) inhibitors may raise blood pressure since their antiprostaglandin properties affect the kidneys. There does not appear to be a direct relationship between caffeine and chronic hypertension, even though caffeine intake can cause an acute (rapid but brief) increase in blood pressure. This may be due to the fact that tolerance to caffeine develops rapidly. Chronic overuse of alcohol is a potentially reversible cause of hypertension. Five percent of hypertension is due to alcohol consumption and 30 to 60 percent of alcoholics have hypertension. Alcohol-induced hypertension is more likely to occur in women than men.
Toxemia is characterized by extreme hypertension, protein loss in the urine, and fluid retention and can be fatal for the mother and or the fetus.17 Fortunately, optimal nutrition can help prevent this disorder. Both too much and too little weight gain increase risk of hypertension during pregnancy. Inadequate salt intake may also increase the risk, so women should not attempt to restrict salt intake during pregnancy. Low calcium and or zinc intake sharply increases risk of toxemia. Calcium supplementation (2g day) during pregnancy may reduce risk of toxemia by a third (see Fig. 4.5).17 Supplemental vitamin B6 (25-50 mg day) and evening primrose oil (containing gLa) (see pp.89) may also be helpful in preventing and or treating this disorder.
Risk factors that can predispose people to hypertension include obesity, smoking, high stress, poor kidney function, and poor diet. Most regular exercisers are not obese, do not smoke, and eat a healthier-than-average diet, thus eliminating several risk factors. Many active people, in fact, have low blood pressure. But you cannot change additional predisposing factors such as your genetics, age, and race that can sometimes cause high blood pressure in spite of all your good health habits. You also cannot overlook the fact that blood pressure increases as we age as many as 70 percent of people over age 65 have high blood pressure. In a study of people 30 to 54 years of age with borderline high blood pressure, those who reduced their sodium intake for 10 to 15 years experienced 25 percent fewer heart attacks and other cardiovascular events compared with those who consumed their standard sodium-rich meals (Cook et al. 2007). If you have high blood pressure, you may believe that salt...
Hypertension is commonly treated with medication, and a combination of two or more drugs is common. Patients are usually given a diuretic to help them excrete excess fluids. However, most diuretics also cause excretion of potassium in the urine, and individuals on diuretics should monitor their potassium intakes. Drugs used to control hyertension include beta-blockers (e.g., atenolol Tenorim ) which act to slow heart rate and cause some vasodilation (widening of the lumen, or interior, of blood vessels). Drugs that contain calcium channel blockers (e.g., amlopidine Norvasc ) or angiotensin-converting enzyme (ACE) inhibitors also cause vasodilation.
Sodium intake has been a primary target for hypertension control, though it is ranked fourth as the lifestyle factor associated with hypertension. About 50 percent of individuals appear to be sodium sensitive. This means that excessive sodium intake tends to increase blood pressure in these groups of people, and they do not appear to excrete excessive amount of salt via the kidneys. Sodium-sensitive individuals include the elderly, obese individuals, and African Americans. The Dietary Guidelines for Americans recommend that adults consume no more than 2,400 milligrams of sodium daily. There are a number of ways to limit sodium in the diet, including Potassium supplements (2-4 grams daily) have been shown to moderately decrease blood pressure. Fruits and vegetables are excellent sources of potassium. The Dietary Guidelines for Americans recommend that adults consume at least 3,500 milligrams of potassium daily. A diet high in fruits and vegetables has been linked to a decreased risk of...
It has been proposed that GABA plays an important role in the modulation of cardiovascular function16 by acting in not only the CNS but also peripheral tissues . 1718 Indeed, GABA has been reported to reduce blood pressure in experimental animals2 and humans3 following its systemic or central administration, and it has been suggested that the depressor effect induced by systemic administration of GABA619 is due to the blockade of sympathetic ganglia Studies have evidenced that GABA plays an important role in the antihypertension effect induced by systemic or central disease, and improves the hypertension occurring in the spontaneously hypertensive rat (SHR) .20-23 The results show that GABA may have a relationship with increased norepinephrine. 24,25 High blood pressure is caused by a high-salt diet in animals, but consumption of GABA can reduce blood pressure effectively.7,26 Therefore, dietary GABA should improve blood pressure .
Chronic hypertension is a medical problem for at least two reasons. First, if the pressure in the arteries is elevated, as occurs in hypertension, the heart has to work harder to generate more pressure to keep the blood flowing. This extra work causes the heart muscle to become overworked and become enlarged (hypertrophy). Over time an enlarging heart from high blood pressure can become dysfunction and eventually fail. The second complication associated with chronic hypertension is that the elevated pressure can traumatize blood vessel walls, which leaves them more susceptible to atherosclerotic development, as explained previously. Hypertension can result in other medical complications such as damage to nephrons, the tiny blood processing units of the kidneys. High blood pressure physical damages artery walls thereby promoting atherosclerosis.
Hypertension is a disorder of circulation in which elevated blood pressure results in increased tension in the walls of the blood vessels. Since it is impossible to routinely measure blood vessel wall tension, hypertension is assessed indirectly by measuring blood pressure. Thus, high blood pressure and hypertension are used to describe the same condition. Almost one in three adults in the United States and Australia and one in five Canadian adults have high blood pressure. In addition, there is higher incidence in African-American adults than Caucasian or Hispanic-American adults. However, no one is safe. Despite such high occurrence, many people (perhaps 30 percent) with high blood pressure don't even realize their blood pressure is elevated. This is because they have not really experienced significant symptoms or have not had a physical examination in a long time. For these reasons, high blood pressure is often referred to as the silent killer.
The major dietary risk factors for hypertension and stroke are as follows 4 Overweight. Obesity is commonly associated with high blood pressure. Overweight hypertensive persons who lose weight often experience a significant reduction in blood pressure.21 intake of essential PUFAs can increase risk of high blood pressure (see Fig. 5.9). 0 Salt. Although for most people sodium in the diet plays only a minor role in determining blood pressure, some individuals are very sensitive to sodium in the diet. Individuals with a family history of hypertension or who are older than 55 years are most likely to be sodium sensitive.22 In about one-third of cases of hypertension, blood pressure can be significantly lowered by limiting sodium intake, most of which comes from salt added to processed foods, such as bread, cheese, canned soups and salty snacks. 0 Potassium. High sodium intake is a much stronger risk factor when combined with low potassium intake.5 People with low intakes of potassium are...
The Centers for Disease Control and Prevention (CDC) reports that 64 percent of men seventy-five and older have hypertension (high blood pressure), and African Americans are at a greater risk. Termed the silent killer, hypertension often has no physical symptoms. Men often feel well enough to function normally in their day-to-day lives, and they do not view the risk as a serious one. Being obese is associated with hypertension. Losing weight helps to control blood pressure, and sometimes men are able to decrease or discontinue their medication if their physicians determine it is no longer needed. Getting men to move away from large portions of fatty meat and potatoes and more toward three ounces of meat on a plate of overflowing vegetables is one sure method to help prevent overweight and manage hypertension. Additionally, some men are sensitive to dietary salt (sodium chloride). Eating too much salt can cause the body to retain water, resulting in increased blood pressure. Processed...
High blood pressure, or hypertension, is a major risk factor for heart disease, stroke, kidney failure, and other conditions. It affects about 65 million Americans ages six years and over and about one-third of adults. Many don't know it. Are you at risk These are some factors linked to high blood pressure family history of high blood pressure, overweight, excessive alcohol intake, advancing age, and smoking. Why is attention given to sodium There's a direct, progressive link between increased high blood pressure and sodium intake. For many people, high-sodium intake is one dietary factor linked to high blood pressure or perhaps its early prehypertension stage. Likewise, reducing sodium intake may help to lower blood pressure if it's high. Although the scientific reasons aren't yet fully understood, foods high in potassium may help protect against high blood pressure. Potassium appears to blunt the effect of sodium on blood pressure. In fact, the DASH (Dietary Approaches to Stop...
Prehypertension Stage 1 Hypertension You have high blood pressure see your doctor and Stage 2 Hypertension SECONDARY HYPERTENSION Persistently elevated blood pressure caused by a medical problem. PRIMARY (ESSENTIAL) HYPERTENSION A form of hypertension whose cause is unknown. Individuals with a systolic blood pressure of 120 to 139 mm Hg or a diastolic blood pressure of 80 to 89 mm Hg are considered prehypertensive and require health-promoting lifestyle modifications to prevent cardiovascular disease. Systolic blood pressure is the key determinant for assessing the presence and severity of high blood pressure in middle-aged and older adults. Hypertension occurs in more than two-thirds of individuals after age 65. Controlling systolic hypertension significantly reduces heart attack, heart failure, and stroke. When persistently elevated blood pressure is due to a medical problem such as a hormonal abnormality or an inherited narrowing of the aorta (the largest artery leading from the...
Does moderate drinking reduce the risk for heart disease Maybe, although for heart health benefits people who don't drink aren't advised to start. Moderate drinking (red or white wine, beer, or distilled spirits) may offer heart-health benefits for some people. Moderate drinking also may raise HDL levels and keep some LDL cholesterol from forming, according to recent research. Resveratrol, a phytonutrient in the skins and seeds of grapes, may function as an antioxidant, promoting heart health it also may help keep blood platelets from sticking together. There's a fine line between how much alcohol is protective, though, and how much instead may promote heart disease, high blood pressure, and strokes. Remember, alcohol also can raise triglyceride levels. Stick to moderation. Excessive and binge drinking is risky. Besides potentially leading to high blood pressure, heart failure, and excess calories, too much drinking can lead to stroke, irregular heartbeat, and sudden cardiac death....
Hypertension ( ) high blood pressure elevation of the pressure in the bloodstream maintained by the heart potassium. In 1989, 9.3 million of the black population (30.1 ) had incomes below the poverty level. Individuals who are economically disadvantaged may have no choice but to eat what is available at the lowest cost. In comparison to other races, African Americans experience high rates of obesity, hypertension, type II diabetes, and heart disease, which are all associated with an unhealthful diet. Obesity and hypertension are major causes of heart disease, diabetes, kidney disease, and certain cancers. African Americans experience disproportionately high rates of obesity and hypertension, compared to whites. High blood pressure and obesity have known links to poor diet and a lack of physical activity. In the United States, the prevalence of high blood pressure in African Americans is among the highest in the world. The alarming rates of increase of obesity and high blood pressure,...
It is quite clear that nutritional intake is associated with common health conditions such as obesity, hypertension (high blood pressure), cancer, diabetes (high blood sugar), and cardiovascular disease. People in the United States make daily decisions related to grocery purchases, meal choices, food preparation, and other factors influencing their consumption of food and nutrients, and, thus, likely affecting their health. However, much of the current knowledge and most published works are based on studies or other information that concern the general population. This information is important in influencing dietary patterns, but additional information is needed regarding specific regional and minority populations. Additionally, more detailed information is necessary to determine if there are any differences or similarities between these subpopulations. What follows is a general literature review related to minority groups in the United States.
Magnesium deficiency is common in both type 1 and type 2 diabetes (20-40 of diabetics are deficient) and may reduce insulin sensitivity and increase risk of high blood pressure, heart disease, and eye disease.5 Hypertension. Magnesium can help control high blood pressure, particularly systolic hypertension.2,11 Many diuretics used to treat hypertension sharply increase magnesium loss. Magnesium is also used to control hypertensive disorders of pregnancy (eclampsia).
With people living longer, and with low birth weight at an all-time low, Asian health should be improving. But with increased Westernization of the Asian diet, elevated tobacco use (generally among Asian men), and lifestyle changes (such as decreased physical activity), there has been a marked rise in cardiovascular disease (CVD), diabetes mellitus, hypertension (high blood pressure), and certain cancers. Obesity is also a growing health problem in Asia, and is strongly associated with hypertension (along with body mass index and age). Despite the low obesity levels in the Asia Pacific region, rates of obesity-related diseases such as diabetes and CVD are on the rise. High blood pressure is also a growing problem in Asia. In India, Indonesia, and Thailand alone, nearly 10 to 15 percent of adults have high blood pressure. Hypertension is dangerous because it increases a person's risk of developing CVD or having a stroke.
Rice has been the mainstay of treatment for a number of conditions, particularly for hypertension at a time when few effective drug therapies were available. In the 1940s, Walter Kempner developed a treatment for mild, and even malignant, hypertension at Duke University. His hypothesis was that a low-protein diet, free of salt, would be an effective treatment. He devised the rice diet, which consisted of rice, fruits, and vegetables. This treatment had good results the blood pressure of his patients fell, and even malignant hypertension was partially reversed. In addition, blood cholesterol levels also fell. hypertension high blood pressure
A health gap separates Central and Eastern Europe from the United States, Canada, Japan, and the Western part of Europe. This East-West gap in health started during the 1960s. Almost half of this gap was due to cardiovascular disease (CVD) mortality differentials. There has been a marked increase of CVD in Central and Eastern Europe, which is only partially explainable by the high prevalence of the three traditional CVD risk factors (hypercholesterolemia, hypertension, and smoking) in these countries. There is an extreme nonhomogeneity of the former Soviet bloc, and the data from each country must be analyzed individually. The aim here is to present the latest available data, which show the health status of various regions of postcommunist Europe. All data used are taken from the World Health Organization (WHO) Health for All Database (as updated in June 2003). The last available data from most countries are from the year 2002. hypertension high blood pressure
As estrogen levels drop with menopause, women no longer have the same protection that estrogen gives from heart disease and high blood pressure. HDL levels drop triglyceride levels increase. That's true whether menopause is natural or surgical. As a result, women's heart-disease risks parallel those of men seven to ten years later in life Their death rate is higher, perhaps due to increased age or more risk factors. In fact, heart disease (not breast cancer) is the top killer and disabler of American women a woman is three times more likely to get cardiovascular disease than breast cancer. About two-thirds of women who die of heart disease had no previous symptoms. Prevent high blood pressure, or lower your blood pressure to optimal levels. Choose and prepare foods with little salt consume potassium-rich foods to blunt sodium's effects on blood pressure. Refer to chapter 22 for more on heart disease, high blood pressure, and diabetes.
Hypertension high blood pressure Homeless adults also suffer several medical problems due to undernutrition. Common problems include anemia, dental problems, gastric ulcers, other gastrointestinal complaints, cardiovascular disease, hypertension, hypercholesterolemia, acute and chronic infectious diseases, diabetes, and malnutrition.
. . . if caffeine causes high blood pressure Since caffeine is a mild stimulant, you may think so. However, studies show that caffeine may result in only a very slight, temporary rise in blood pressure level. If your doctor prescribes antihypertensive medication, take it faithfully. If other tactics, like weight loss, lower your blood pressure level, taking medication may not be forever. Follow directions for medications carefully. Different blood pressure medications work in different ways some may interact with other medications for example, for diabetes or kidney disease.
If sodium is the bad guy that contributes to high blood pressure, then potassium is the good guy that helps lower blood pressure. Potassium is found in most whole foods fruits, vegetables, whole-grain breads and cereals, lentils, beans, nuts, and protein foods. Refined or highly processed foods, sweets, and oily foods (e.g., salad dressing, butter) are poor sources of potassium. You can increase your potassium intake by eating the following kinds of foods
The ''lag-time'' effect of risk factors for CVD means that present mortality rates are the consequence ofprevious exposure to behavioural risk factors such as inappropriate nutrition, insufficient physical activity and increased tobacco consumption. Overweight, central obesity, high blood pressure, dyslipidaemia, diabetes and low cardio-respiratory fitness are among the biological factors contributing principally to increased risk. Unhealthy dietary practices include the high consumption of saturated fats, salt and refined carbohydrates, as well as low consumption of fruits and vegetables, and these tend to cluster together.
Cardiovascular disease is responsible for over 900,000 deaths a year, and remains the number one killer of Americans. In addition, over 1.5 million people had a heart attack this past year, and sixty million Americans have high blood pressure. All told, forty million Americans suffer from cardiovascular disease, and many times that number are unaware they are at severe risk of cardiovascular disease.
Hypertension, or high blood pressure, although easily diagnosed, has no obvious symptoms. Stroke typically causes brain damage without warning. Cancer is often not detected until it has metastasized (spread throughout the body).10 In fact, most of the degenerative biological processes that result in devastating clinical disease are invisible and silent, and most of these, and the deaths and suffering they cause, can be prevented or significantly delayed.
Studies have shown that exercise can have a direct effect on preventing heart disease, cancer, and other causes of premature death. Furthermore, participation in regular physical activity may reduce the rate of occurrence of these maladies. An inverse relationship exists between disease and exercise, meaning that with increased levels of physical activity there is a decreased prevalence for certain diseases. Currently, there is strong evidence that exercise has powerful effects on mortality, CAD (including blood lipid profiles), and colon cancer. Research has also confirmed that aerobic exercise can reduce high blood pressure, obesity, type II diabetes, and osteoporosis. In addition, stroke and several types of cancer (such as breast, prostate, and lung cancer) can also be reduced with regular physical activity. Even more important, several of these factors are interrelated. For example, when an individual lowers his or her high blood pressure, the risk for heart disease, stroke, and...
No matter what your health concerns-preventing cancer, heart disease, diabetes, obesity, high blood pressure, whatever-the bottom-line message from every health organization (including the American Heart Association the American Cancer Society the National Heart, Lung and Blood Institute and the US DA) is to eat more fruits and vegetables. Yet, more than 90 percent of Americans fail to consume the recommended amount. By combining the best food choices from the food guide pyramid with a regular exercise program, you can invest in your future well-being. Although genetics do play a strong role in heart disease, cancer, hypertension, and osteoporosis, you can help put the odds in your favor by eating wisely. As Hippocrates said, Let food be thy medicine.
Many question the one size fits all recommendation because not everyone is saltsensitive. However, there is no test for salt sensitivity therefore, it makes sense for everyone to play it safe and follow a prudent approach. Most health professionals recommend limiting your intake of sodium to no more than 2,400 milligrams per day. This includes both the salt you add and the sodium that is already present in foods you eat. Become familiar with the following list of high-sodium foods, and learn to balance your diet so you don't go sodium overboard. Note, if you have high blood pressure, your doctor might prescribe a more severe sodium restriction.
Other good potassium sources Dry beans, lentils, peas, almonds, and peanuts. Milk and yogurt supply calcium and potassium, perhaps protecting against high blood pressure. the DASH plan diet and lowered their sodium intake to 1,500 milligrams daily had even better blood-pressure-lowering results especially if they had hypertension. To learn more, see Blood Pressure Under Control and specifically DASH to Health in chapter 22. Consider following the DASH plan whether or not you have high blood pressure. If you have it or some other health condition, your doctor might recommend less sodium than you consume now. Consult your doctor for the right sodium level for you, and a registered dietitian (RD) to help you follow this advice.
Phytonutrients are bioactive compounds in food that promote your health by helping to slow the aging process or reducing the risk for many diseases. Since the early 1980s, research has intensified in investigating how phytonutrients protect against some cancers, heart disease, stroke, high blood pressure, cataracts, osteoporosis, urinary tract infections, and other chronic health conditions.
Heart disease is the leading cause of death among Native Americans. Risk factors, such as high blood pressure, cigarette smoking, high blood cholesterol, obesity, and diabetes, are health conditions that increase a person's chance for having heart disease. The more risk factors a person has, the greater chance a person may have for developing heart disease. Sixty-four percent of Native American men and 61 percent of women have one or more of these risk factors.
For most adults, occasional moderate alcohol drinking (one to two drinks per day) is not harmful, and may have health benefits. Moderate alcohol drinking can increase the HDL-cholesterol level in the blood, decrease risk of blood clots, and reduce risk of heart attack.1 However, regular heavy drinking (more than three to four drinks per day) is a health hazard. (A drink is considered a 180-ml glass of wine, 360-ml glass of beer, or 30-45 ml of spirits.) Heavy drinking increases risk of high blood pressure, stroke, liver disease, im
It has been argued that while nutritional factors such as calcium intake may modify the risk of preeclampsia, eclampsia, and hypertension, it is unlikely that nutritional factors are important in reducing the risk of mortality due to these causes. This argument is based on data that show that mortality due to preeclampsia, eclampsia, and hypertension has not decreased or varied over time or by condition 43 .The recent WHO systematic review of causes of maternal mortality shows high regional variation in preeclampsia associated mortality 11 , suggesting that the above argument is refutable. Historically, observations that Mayan Indians who consumed a traditional diet of corn soaked in lime had high calcium intakes 44 , and Ethiopian women whose diets contained high amounts of calcium had low rates of preeclampsia 45 support the role of calcium in reducing hypertensive disorders of pregnancy. A dietary deficit in calcium is postulated to cause an increase in blood pressure due to...
In some studies, exposure to even low levels of cadmium has been associated with high blood pressure (hypertension). Experimentally, adding 5 ppm cadmium to drinking water produced elevated blood pressure. Adding zinc reversed this effect, and lowered blood pressure to normal. In other studies even concentrations as low as 0.1 ppm caused hypertension. Subsequent studies have found an anomalous effect. When low doses of cadmium were given, test animals developed hypertension, but high doses induced low blood pressure. The cause of the hypertension appears to be related to the blocking of two enzymes needed to break down the hormone norepinephrine, which normally constricts blood vessels and raises blood pressure. If it cannot be cleared from the blood vessel walls, the vessels remain constricted and the blood pressure elevated. Why higher doses lowered blood pressure is still a mystery. The natural question is is cadmium responsible for hypertension Unfortunately, the answer is not...
In the United States, most people regularly consume much more sodium than they need. In fact, some people who are sodium-sensitive may end up with high blood pressure that can be lowered if they reduce their sodium intake. For more about high blood pressure, check out High Blood Pressure For Dummies (published by Wiley) by Alan L. Rubin, M.D.
Get a thorough check-up before beginning a fitness program. This is especially important if you're over 35, have been sedentary for a long time, have high blood pressure and or cholesterol, are a smoker, or have chest pains or shortness of breath. Hopefully, your doctor will be thrilled you're making this lifestyle change, and will tell you if you have any limitations.
The body has a nearly unlimited capacity to store fat. Excess fat in the abdomen can lead to illnesses, including diabetes, high blood lipid levels, and high blood pressure. It is also associated with an increased risk for coronary artery disease, stroke, and certain cancers. Losing weight will reduce these risks and lessen the strain on the lower back, hips, and knees.

Guidelines for cancer prevention are similar to those for preventing other health problems, including heart disease, diabetes, and high blood pressure. This same eating approach promotes overall well-being. Throughout this book you'll find practical tips for eating to prevent cancer. Keep in mind that no single food or nutrient causes or prevents cancer.
So what's your healthy weight That depends. Determining your right weight takes several things into account (1) your body mass index, or your weight in relation to your height (2) the location and amount of body fat you have and (3) your overall health and risks for weight-related problems such as diabetes or high blood pressure.
Those at risk for or with high blood pressure are better off with less. Note For people with hypertension, African Americans, and middle-aged and older adults, the Dietary Guidelines advise Aim to consume no more than 1,500 milligrams of sodium per day, and meet the potassium recommendation (4,700 milligrams per day) with food.
For a long time fat tissue and their cells were viewed as somewhat inert containers of energy storage. However, today we know that adipose tissue functions as a gland with the capability to release a variety of factors relative to its size and endowed energy. As mentioned previously, some of these factors may promote the formation of more fat cells. Perhaps some of the most interesting released factors are those that circulate to the brain and provide insight to our energy storage status. One of the most important factors seems to be the hormone leptin. Fat cells release more and more leptin into our circulation when fat cells accumulate more fat. Leptin then signals the brain to reduce appetite. In addition, as fat cells swell due to excessive calorie consumption, some of the chemicals they release can promote the development and worsening of diabetes, high blood pressure and other medical conditions.
Southern Europeans experience less heart disease, stomach and lung cancers, strokes, high blood pressure, diabetes, and obesity than other Western nations. This lower rate of chronic disease has been attributed to diet. The diet of people in this area is similar to that recommended in the American Food Guide Pyramid. It differs mainly in the amount of meat and dairy consumed. high blood pressure elevation of the pressure in the bloodstream maintained by the heart Although the dietary habits described above are traditionally true, recent trends show that the southern European diet now also includes elements of the Western fast-food craze. A study by Eurostat, the European Commission's statistical branch, found that southern Europeans are getting fatter. Thirty-five percent of Greek males are overweight, as are 32 percent of Spanish males. Thirty-one percent of Greek and Portuguese women are overweight. Rates of high blood pressure, heart disease, and diabetes are increasing.
High blood pressure is a major risk factor for coronary heart disease and both forms of stroke (ischaemic and haemorrhagic). Of the many risk factors associated with high blood pressure, the dietary exposure that has been most investigated is daily sodium intake. It has been studied extensively in animal experimental models, in epidemiological studies, controlled clinical trials and in population studies on restricted sodium intake (36, 37). All these data show convincingly that sodium intake is directly associated with blood pressure. An overview of observational data obtained from population studies suggested that a difference in sodium intake of 100 mmol per day was associated with average differences in systolic blood pressure of 5 mmHg at age 15--19 years and 10 mmHg at age 60--69 years (37). Diastolic blood pressures are reduced by about half as much, but the association increases with age and magnitude of the initial blood pressure. It was estimated that a universal reduction...
The prevalence of overweight and obesity is reaching epidemic proportions nationally and worldwide.75,76 In the U.S., 55 of adults aged 20 years and older are either overweight or obese. Overweight is defined as having a body mass index (BMI) of 25.0 to 29.9 kg m2 and obesity as BMI equal to or greater than 30 kg m2. Similar trends are observed in children and adolescents with a doubling of the number of obese children from 20 years ago.75 Obesity is a major risk factor for coronary heart disease, hypertension, type 2 diabetes, stroke, gallbladder disease, osteoar-thritis, respiratory problems, and some cancers. In addition to the enormous health consequences that result in increased health care costs, there are significant social and psychological burdens for obese individuals and their families.77 C. Hypertension Guidelines High blood pressure is one of the most common health problems in industrialized countries. Among U.S. adults, about one fourth suffer from hypertension. Certain...
On the other hand, vitamin D is fat soluble, so taking large supplemental doses can be dangerous. Some of the toxic effects involve drowsiness, diarrhea, loss of appetite, headaches, high blood pressure, high cholesterol, fragile bones, and calcium deposits throughout your body (including your heart, kidneys, and blood vessels). If you are taking supplements, make sure you're not getting much more than the recommended amount for your age category you'll notice that folks over 50 need more. Also, note that the adequate intake (AI) for vitamin D is given in micrograms on the chart the vitamin D in food and supplements is usually measured in international units (IU)-The conversion is one microgram 40 international units (IU).
People with a higher percentage of body fat tend to have a higher BMI than those who have a greater percentage of muscle. Carrying excess body fat puts you at greater risk for health problems such as heart disease, diabetes, certain cancers, and high blood pressure. The higher your BMI, the greater your risk.
Evidence suggests that magnesium may play an important role in regulating blood pressure. Diets that provide plenty of fruits and vegetables, which are good sources of magnesium and potassium, are consistently associated with lower blood pressure. The Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure recommends maintaining an adequate magnesium intake, as well as potassium and calcium intake, as a positive lifestyle modification for preventing and managing high blood pressure.
The major causes of death in developed countries today are heart disease, high blood pressure, strokes and cancer. These are not just diseases of old age, although it is true to say that the longer people live, the more likely they are to develop cancer. Heart disease is a major cause of premature death, striking a significant number of people aged under 40. This is not solely a Western phenomenon. As countries develop, so people in the prosperous cities begin to show a Western pattern of premature death from these same diseases.
Have you gained and lost the same 10, 20, or even 30 pounds over and over again The cycle of repeatedly losing and regaining weight can make weight management more difficult in the long run. Lost weight that repeatedly comes back may lead to feelings of frustration, failure, and poor self-esteem. According to some studies, weight cycling may even increase the risk for ongoing health problems such as high blood pressure, high cholesterol, and gallbladder disease.
An adequate amount of calcium is important for controlling high blood pressure and not only for the person who takes the calcium directly. At least one study shows that when a pregnant woman gets a sufficient amount of calcium, her baby's blood pressure stays lower than average for at least the first seven years of life, meaning a lower risk of developing high blood pressure later on.
Many religious leaders and health care experts regard tobacco, another stimulant, as a malignant poison that affects the health of its users. Research continues to support the harmful and deleterious effects of the use of cigarettes and tobacco products. Cancer, high blood pressure, and heart disease have all been linked to tobacco use.
MyPyramid is meant for healthy people. If you have diabetes, high blood pressure, or other health problems (or if you're at risk for them), your food and nutrient needs may differ. Get advice from a registered dietitian or your doctor. Refer to chapter 22, Smart Eating to Prevent and Manage Disease.
The relative proportion of fat-free mass to fat mass in the body. Fat-free mass is composed of muscle, bone, organs, and water, whereas fat is the underlying adipose tissue. Excessive fat is a good predictor of health problems because it is associated with cardiovascular disease, high cholesterol, and high blood pressure. Higher proportions of fat-free mass indicate an increase in muscle, and thus an increased ability to adapt to everyday stress.
Healthy People 2010 expands on the Healthy People 2000 objectives, while also addressing emerging issues such as obesity and mental health. For example, obesity has been linked to many other health concerns such as high blood pressure, diabetes, cancer, and heart disease. Therefore, one objective of Healthy People 2010 is to promote health and reduce chronic disease associated with diet and weight. This objective will focus on weight status and growth food and nutrient consumption iron deficiency and anemia schools, worksites, and nutrition counseling and food security. high blood pressure elevation of the pressure in the bloodstream maintained by the heart
Measures more than 35 inches and a man whose waist measures more than 40 inches may be at particular risk for developing health problems. Studies indicate that increased abdominal or upper-body fat is related to the risk of developing heart disease, diabetes, high blood pressure, and stroke and is associated with an overall likelihood of death, especially premature death. Body fat concentrated in the lower body (around the hips, for example) seems to be less harmful.
Let's use calcium-channel blocker drugs, which are used to treat high blood pressure and angina, as an example. Calcium-channel blockers (also called calcium blockers or CCBs) inhibit the opening of calcium channels (pores) on heart muscle cells and muscle cells lining certain blood vessels. This reduces contraction of the muscle cells and as a result the heart pumps less vigorously and blood vessels relax, both contributing to a lowering of blood pressure and reduced stress on the heart.
An excessive intake of a mineral may also have serious consequences for health. Too much sodium in the diet may be associated with high blood pressure and increased risk of a stroke. A condition known as siderosis, in which an excess of iron is deposited in the body, can result when too much iron is absorbed. Selenosis, a sometimes fatal effect of an excessive intake of selenium is known to occur in parts of China where high levels of the element enter locally grown foods from selenium-rich soil. Less serious effects, such as nausea, can be caused by a high intake of zinc.
We hear much more about vitamins than minerals, but minerals are certainly no less important to our health, and are critical for even basic survival. Science has been focusing more attention on their potential link to our protection from major chronic diseases like high blood pressure, osteoporosis, cardiovascular disease and cancer with promising results. As mentioned earlier, too much iron may play a crucial role in oxidation. Researchers in Finland studied about two thousand healthy men for three years. They tracked twenty risk factors for heart disease, and at the end of the study the risk of heart disease was twice as great for those men with high blood levels of iron. The only other risk factor more significant was smoking. *112 We have also mentioned the contributing role that a little known mineral, boron, may play in offering protection from osteoporosis. Certainly calcium is at the forefront of osteoporosis prevention. There are more than sixty minerals in the body which...
Fruits and vegetables contribute to cardiovascular health through the variety of phytonutrients, potassium and fibre that they contain. Daily intake of fresh fruit and vegetables (including berries, green leafy and cruciferous vegetables and legumes), in an adequate quantity (400-500 g per day), is recommended to reduce the risk of coronary heart disease, stroke and high blood pressure. Fibre is protective against coronary heart disease and has also been used in diets to lower blood pressure. Adequate intake may be achieved through fruits, vegetables and wholegrain cereals.
The increased life expectancy and low rates of chronic diseases such as heart disease, high blood pressure, diabetes, and cancer among the southern Europeans, may be, in part, due to their physically active, simple lifestyle and unique Mediterranean diet, which is especially rich in a variety of phytochemicals such as those found in olive oil, garlic and other herbs, beans, fresh fruit and vegetables.145,146
There is increasing evidence that among term and pre-term infants, breastfeeding is associated with significantly lower blood pressure levels in childhood (37, 38). Consumption of formula instead of breast milk in infancy has also been shown to increase diastolic and mean arterial blood pressure in later life (37). Nevertheless, studies with older cohorts (22) and the Dutch study of famine (39) have not identified such associations. There is increasingly strong evidence suggesting that a lower risk of developing obesity (40--43) may be directly related to length of exclusive breastfeeding although it may not become evident until later in childhood (44). Some of the discrepancy may be explained by socioeconomic and maternal education factors confounding the findings. In a study of 11-12 year-old Jamaican children (26), blood pressure levels were found to be highest in those with retarded fetal growth and greater weight gain between the ages of 7 and 11 years. Similar results were found...
Complications from hypertension are a leading cause of pregnancy-related deaths, ranking third behind hemorrhage and embolism 2 . Hypertensive disorders that may be found during pregnancy include chronic hypertension, preeclampsia- eclampsia, preeclampsia superimposed on chronic hypertension, and gestational hypertension 3 . Chronic hypertension is hypertension that exists outside of the pregnancy. As such, it will predate the pregnancy, be documented prior to 20 weeks, or will still be present 12 weeks after delivery 3 . Treatment of mild-to-moderate chronic hypertension during pregnancy has not been shown to prevent preeclampsia and has shown no proven fetal benefit 4-6 . Preeclampsia-eclampsia is the onset of hypertension with proteinuria that occurs after 20 weeks of pregnancy. Eclampsia, which occurs in less than one percent of women with preeclampsia 1 , is the new onset of seizures during preeclampsia. If a patient has chronic hypertension but develops new or worsened...
Summary Preeclampsia is a multi-organ disease that is specific to pregnancy and is characterized by the development of proteinuria and hypertension. It complicates 5-7 of pregnancies and specific criteria must be met for diagnosis. The exact etiology or pathophysiology of preeclampsia is poorly understood and as such, there are no well-established methods of primary prevention or of reliable and cost-effective screening. Calcium and aspirin may have a role in preventing preeclampsia in certain subpopulations, and research continues regarding these and other possible nutritional interventions. Preeclampsia is associated with increased maternal mortality and morbidity, and childbirth is the only known cure. Women with preeclampsia need to have regular surveillance. The associated hypertension may warrant treatment under certain conditions and magnesium sulfate is the drug of choice for the prevention and treatment of eclamptic seizures. Keywords Preeclampsia, Eclampsia, Hypertensive...
The National Health and Nutrition Examination Survey found an incidence of endstage renal disease of 0.23 100 person years, with rates of 0.29 for patients with type 1 diabetes and 0.27 for patients with type 2 diabetes (90). Factors such as African American race, gout, and hypertension more than doubled the risk of endstage renal disease (90). In a study by Klein et al., analyzing 891 patients with type 1 diabetes, the 10-year cumulative incidence of renal failure or serum creatinine 2.0 mg dl was 14.9 percent (90). The risk of renal failure almost doubled for every 1 percent increase in HbA1c (36). Hypertension almost tripled the risk (90).
Production of nitric oxide (NO ), by hydroxylation of arginine, is a part of normal cell signalling. In addition to being a radical, and hence potentially damaging in its own right, nitric oxide can react with superoxide to form peroxynitrite, which in turn decays to yield the more damaging hydroxyl radical. Nitric oxide was first discovered as the endothelium-derived relaxation factor, and this loss of nitric oxide by reaction with superoxide may be an important factor in the development of hypertension.
When GFR is below normal but not low enough, the kidneys try to maintain relatively normal fluid, electrolyte, and acid-base balance. However, when GFR is severely decreased, the kidneys retain Na+, water, K+, Mg2+, PO3- and H+ ions, resulting in edema, either hyponatremia or hypernatremia, hyperkalemia, hypermagnesemia, hyperphosphatemia, and severe metabolic acidosis. Hypocalcemia results from decreased calcitriol production by the kidney. The patients also develop hypertension due to retention of Na+ and water. Anemia and bone disease are commonly seen in patients with low GFR.
Theories of pathophysiology include genetic predisposition 11-14 , abnormal placental implantation 15, 16 , angiogenic factors 17 , exaggerated inflammatory responses 18 , inappropriate endothelial activation 18 , vasoconstriction 19 , and coagulation cascade defects 19 . Although hypertension and proteinuria are the criteria by which preeclampsia is diagnosed, the pathophysiologic changes associated with preeclampsia affect virtually every organ system. Microthrombi from activation of the coagulation a Both hypertension and proteinuria components must be present b One or more must be present in addition to criteria for preeclampsia c Taken on two occasions at least 6 h apart Chronic hypertension
Although taking a simple multivitamin is unlikely to hurt your health, does taking vitamin supplements improve your health if you already have a good diet In a review of carefully controlled research studies on the impact of vitamin supplements on cancer, heart disease, cataracts, or age-related macular degeneration and hypertension, the National Institutes of Health concluded that the evidence is insufficient to prove the presence or absence of benefits from use of multi-vitamin or mineral supplements to prevent cancer and chronic disease (Huang et al. 2006, National Institutes of Health 2007).
Hypertension The principal diet-related determinants of high blood pressure are obesity, high alcohol intake, high sodium intake, and low potassium intake.30,31 Most comparative studies have found that vegetarians are thinner and have a lower alcohol intake than non-vegetarians, and that they have a higher potassium intake, but there is no consistent evidence that vegetarians have a low sodium intake some vegetarian foods are high in sodium. A number of studies have examined the association of vegetarian diets with blood pressure. Some studies comparing groups of vegetarians and non-vegetarians found lower blood pressure in the vegetarians, but other studies found no difference.32 Randomized trials of the effects of vegetarian diets on blood pressure have shown reductions in blood pressure of around 5 mmHg that were not due to changes in sodium intake and did not appear to be explicable by changes in other relevant nutrients such as potassium.32 Subsequent trials have attempted to...
More and more research concludes that strength training helps reduce anxiety. Your body's response to stress is to release chemicals to prepare your body for it, like adrenaline, norepinephrine, and cortisol. Also called the fight or flight response. Being anxious about the holidays, your job, getting fit, or money also produces the stress response. But you still have those chemicals floating around in your bloodstream. Being sedentary and anxious is where stress wreaks havoc on your health - heart disease, high cholesterol, hypertension, and aging. Lifting against a resistance is a great way to burn up those lingering stress hormones and help you feel better.
While the normal pregnancy is characterized by maternal hemodynamic changes and an insulin resistant state, obesity in pregnancy appears to complicate these expected physiological adaptations to pregnancy. Accordingly, the risk for hypertensive disorders and gestational diabetes (GDM) is reportedly higher in obese and morbidly obese women compared to women who are not obese. In a prospective, multicenter study of more than 16,000 women, Weiss et al. 31 observed a 2.5-fold greater risk of gestational hypertension, and a 2.6-fold greater risk of GDM among obese versus nonobese women. Risk for these conditions was even greater in a morbidly obese subset, e.g., 3.2- and 4-fold respectively. Similarly, these researchers found the risk for developing preeclampsia was 1.6 and 3.3 times more likely to develop in obese and morbidly obese women, respectively. Results from this study have been confirmed by others 32, 33 and found to be independent of other related factors including age, parity,...
Coronary artery disease (CAD) refers to any of the conditions that affect the coronary arteries and reduces blood flow and nutrients to the heart. It is the leading cause of death worldwide for both men and women. Atherosclerosis is the primary cause of CAD. Controlled risk factors associated with CAD include hypertension, cigarette smoking, elevated blood lipids (e.g., cholesterol, triglyceride), a high-fat diet (especially saturated fats and trans-fatty acids), physical inactivity, obesity, diabetes, and stress. Lifestyle changes can assist in prevention of CAD. Uncontrolled risk factors include a family history of CAD, gender (higher in males), and increasing age.
Congenital cardiac anomaly (CAA), also known as congenital heart disease (CHD), refers to any structural defect of the heart or major vessels that exists from birth. It is the most common cause of infant death, other than problems of prematurity, and death is likely to occur in the first year of life. CAA may result either from genetic causes or from external causes such as maternal infection or exposure to other factors that affect embryonic development. The general problems associated with CAA include increased cardiac workload, hypertension, poor oxygenation of blood, and respiratory infections. There are many types of CAA, including aortic stenosis, atrial septal defect, valvular stenosis, and pulmonary stenosis.
There is a high prevalence of cardiovascular disease (coronary heart disease, stroke, hypertension) in this area, mainly due to the high intake of saturated fats, cholesterol, and sodium. Stomach cancer is also very common due to the high intake of salt and salt-cured foods, especially salted fish. Accidental injuries are the largest cause of death for individuals under forty-five years of age. Suicide and alcoholism are also prevalent, and obesity is on the rise.
Overweight children are fraught with many of the same concerns as adults. Socially, overweight and obese kids are subject to teasing and other negative peer interactions leaving them prone to feeling isolated. Medically, the incidence of Type 2 diabetes mellitus in overweight children continues to climb along with the diagnosis of hypercholesterolemia and hypertension. Sadly, about 40 percent of obese children and 70 percent of obese adolescents maintain their obese status into adulthood. In addition, obese children who achieve a healthier weight before becoming adults are more prone to obesity during adulthood than children who never were obese. This is a huge concern as we are all aware of the low success rates of weight reduction and maintenance in adults.
Whether or not you should consider special supplementation designed to protect the brain will depend on a number of factors. If you have lived a hard life, eaten poorly, exercised too little or too much, experienced prolonged, intense stress, or suffered from a chronic disease (such as diabetes, lupus, or hypertension), you will most certainly need intensive nutritional therapy.
However, calcium and aspirin may have a role in preventing preeclampsia in certain subpopulations, though the optimal treatment regimens will require further research. Calcium supplementation in high-risk women and in women with low dietary calcium intakes reduced the risk of hypertension and preeclampsia 25 . Also, calcium supplementation has been shown to decrease the incidence of neonatal mortality and severe maternal morbidity due to hypertensive disorders when given to normotensive nullipa-rous women 26 . Low-dose aspirin was shown to have small to moderate benefits for prevention of preeclampsia within certain groups of women. A Cochrane analysis demonstrated that in women at increased risk for preeclampsia, 69 women would need to be treated with low-dose aspirin to prevent one case of preeclampsia 27 . However, in the subgroup of women at highest risk for preeclampsia (because of histories of previous severe preeclampsia, diabetes, chronic hypertension, renal disease, or...
The mean annual consumption of sucrose plus fructose in developed countries is about 25 of the caloric intake. Fructose is more lipogenic than glucose. This high intake of sucrose (approximately 50 kg year person) has been contentiously implicated in influencing the health of humans, apart from caries, because a high consumption of sucrose fructose in experimental animals (often rats) creates, among other things, hyperlipidemia, insulin resistance, hypertension, and diabetic-like tissue lesions (66). However, while a hyperlipidemic effect of sucrose and fructose has been demonstrated in a number of human studies, firm conclusions cannot be made because of great variations in the type of subjects, duration of intake, background diet, and study conditions ( 66). The general conclusion of an FDA-sponsored survey published in 1986 was that the present voluntary intake of sucrose and fructose is not harmful to humans ( 67). A more recent review, while accepting that the intake of sucrose...
Summary Obesity in pregnancy is associated with numerous maternal and neonatal complications including difficulty conceiving, increased risk of miscarriage, fetal anomalies and mortality, higher rates of gestational hypertension, gestational diabetes and preeclampsia, and an increased risk of cesarean section and delivery related complications. Nevertheless, more women are entering pregnancy with excessive weight and are gaining weight above the Institute of Medicine (IOM) recommendations during pregnancy. Weight loss is not recommended during pregnancy however, overweight and obese women should be advised to aim for a moderate weight loss prior to conception and during the postpartum period. Strategies for achieving moderate progestational and postpartum weight loss include a low-calorie, low-fat diet and at least 45 min of daily physical activity. Benefits to mother and child are achieved with even a moderate weight loss. Importantly, health care professionals should counsel women...
Data from the Centers for Disease Control (CDC) underline a decline in 2004 in the teenage birth rate in the US, with 41.2 births per 1,000 females aged 15-19 years 11 . Rates increased slightly in 2004 for girls aged 10-14 years 11 . These data are worrisome, as these young women are nearer to menarche, and still growing themselves, with increased nutritional needs. These very young women also have increased risk for maternal death 12 . The younger-aged group received the lowest rate of timely prenatal care, highest rates of late or no prenatal care, and was at highest risk of pregnancy-associated hypertension. Among the youngest cohort, pregnancy outcome was poor, e.g., infants were more likely to be preterm, to be born with low birth weight, and to die in their first year at a rate that was three times the overall rate of 15.4 per 1,000 13 .
Since being overweight is associated directly with many chronic illnesses, such as heart disease, hypertension, hyperlipidemia, cancer, stroke, and type II diabetes, an increase in the incidence of overweight and obesity is a serious concern. The top three leading causes of death in the United States during the 1990s were heart disease, cancer, and stroke. Diabetes ranked seventh in 1997 it was not even in the top ten in 1987. The U.S. Surgeon General reported in 1998 that type II diabetes, an adult health problem related to obesity, was being seen in children as young as four years old. Diabetes among adults increased by 70 percent between 1990 and 1998 among individuals 30 to 39 years of age by 41 percent among individuals 40 to 49 and by 31 percent among those 50 to 59. By 1998, 16 million American adults suffered from diabetes. In addition to the health threat, obesity can cause emotional pain due to social stigmatization, discrimination, and lowered self-esteem. In 2000, the...
Many people with diabetes are not aware that they are at particularly high risk for heart disease and stroke, which can result from the poor blood flow that is a symptom of diabetes. In addition, people with type 2 diabetes have higher rates of hypertension and obesity, which are additional risk factors. Diabetics are two to four times more likely to have a heart attack than nondiabetics, and at least 65 percent of people with diabetes die from heart attack or stroke. While deaths from heart disease have
Of the 18,244 cohort participants, 19 (n 3,789) subjects reported eating 200 g (equivalent to about 4 servings) of fish and shellfish per week. The average intake level of seafood in all study subjects was 129.1 g per week (Table 2.1). There was no statistically significant difference in age or body mass index (kg m2) across various categories of fish and shellfish intake. Consumption of fish and shellfish was positively associated with level of education (P 0.001), cigarette smoking (P 0.001), and alcohol drinking (P 0.001). Men with histories of diabetes or hypertension consumed slightly more fish and shellfish (Table 2.1).
In an analysis of the complication rate after bariatric surgery, Schwartz et al. analyzed 600 laparoscopic RYGBs and found the overall complication rate approached 26 percent.12 One of the main predictors of complications is the experience of the surgeon.13 In fact, the American Society of Bariatric Surgeons recommends that a surgeon perform 100 procedures before technical expertise is obtained. The higher the weight (body-mass index 55 kg m2), the more likely there will be complications. Males over 50 years of age are at increased risk of complications. The presence of hypertension and sleep apnea will increase the likelihood of complications. Interestingly, the presence of diabetes is not a predictor of complications.
The metabolic syndrome is a condition characterized by hyperinsulinemia, hypertension, visceral obesity, dyslipidemia, and glucose intolerance, which leads to increased risk of coronary-artery disease and type 2 diabetes. The National Health and Nutrition Examination Survey (NHANES III) indicated that 45 percent of the U.S. population over age 50 has metabolic syndrome, and, because of the increase in the prevalence of obesity, the incidence of the metabolic syndrome has increased by 60 percent over the last decade.
The prevalence of hypertension, cardiovascular disease, and diabetes is greater among African Americans than other groups. Dietary intake has been strongly associated with both of these conditions for many years. Therefore, it seems prudent to focus on diet in an attempt to reduce the number of premature disabilities and deaths as the result of these conditions.
The general increase, however, in the quantity and variety of food available has mostly been accompanied by the emergence of degenerative conditions such as CVD, various types of cancer, non-insulin dependent diabetes mellitus, obesity, osteoporosis and hypertension. Documenting and monitoring dietary patterns has therefore become a priority in the formulation of dietary recommendations and the planning of national food, nutrition and agricultural policies (Soci t Fran aise de Sant Publique. Health and Human Nutrition, 2000).
The exercise recommendations from the American College of Obstetricians and Gynecologists (ACOG) mirror those of the Center of Disease Control (CDC), and the American College of Sports Medicine (ACSM). The ACSM recommends moderate intensity exercise for 30 min or more on most days of the week as part of a healthy lifestyle in the nonpregnant population 4 . A moderate level of exertion for 30 min duration has been associated with significant health benefits decreasing risk of chronic diseases including coronary heart disease, hypertension, type 2 diabetes mellitus, and osteoporosis 33 . Women who are sedentary prior to pregnancy should gradually increase their duration of activity to 30 min. Those who are already fit should be advised that pregnancy is not the time to greatly enhance physical performance and that overall activity and fitness tend to decline during pregnancy. Pregnant women should exercise caution in increasing intensity, especially when an exercise session extends...
Because habits adopted during pregnancy can result in persistent lifestyle improvements, exercise during pregnancy could significantly reduce the lifetime risks of obesity, chronic hypertension and diabetes not only for pregnant women, but also for their families as well. Overall, a woman whose exercise habits have become firmly entrenched during pregnancy stands a much better chance of maintaining them after her child is born.
Absorption of calcium, iron, folic acid, and vitamin B12 69 . While these surgeries have had a positive impact on reducing maternal risk for GDM and hypertensive disorders, case reports of intrauterine growth restriction, premature birth, and NTDs have been described 70 . Because of these limitations, the laparoscopic adjustable gastric banding procedure is being used more frequently as a means of restricting stomach volume, decreasing intake, and promoting weight loss 71 . The adjustability of banding also allows for adaptations to altered requirements of pregnancy. Early reports on follow-up of pregnant women who have had this type of procedure are encouraging and indicate reduced risk of malabsorption, GDM, gestational hypertension, and preterm deliveries 71 . To ensure optimal pregnancy outcome and minimize maternal and fetal risks, the American College of Obstetricians and Gynecologists recommends that women delay pregnancy for 12-18 months after surgery to avoid pregnancy during...
Summary In most developing countries, including Chile, an epidemiologic and nutrition transition has taken place, the former characterized by an increase of the population due to a reduced mortality, followed by a decrease in fertility and an increase in longevity. The nutrition transition has been characterized by an increase in the consumption of fats and simple sugars and a decrease in fruit and vegetable intake. This, together with a decrease in physical activity, has contributed to an increase in the prevalence of obesity in fertile women. Data collected from 36 developing countries showed that in 32 of them, overweight was more prevalent than underweight in urban areas, while in 53 (19 36) underweight was more prevalent in rural areas compared to urban settings. In all of those countries, the prevalence of overweight was significantly correlated with gross national income per capita. Different surveys in Chile have shown that 90 of homes have a television set, 60 of all families...
