There is also convincing evidence to indicate that physical activity decreases the risk of colon cancer. Factors which probably increase risk include high dietary intake of preserved meats, salt-preserved foods and salt, and very hot (thermally) drinks and food. Probable protective factors are consumption of fruits and vegetables, and physical activity (for breast cancer). After tobacco, overweight and obesity appear to be the most important known avoidable causes of cancer. Cancers of the oral cavity, pharynx and oesophagus. In developed countries the main risk factors for cancers of the oral cavity, pharynx and oesophagus are alcohol and tobacco, and up to 75 of such cancers are attributable to these two lifestyle factors (5). Overweight and obesity are established risk factors specifically for adenocarcinoma (but not squamous cell carcinoma) of the oesophagus (6-8). In developing countries, around 60 of cancers of the oral cavity, pharynx and oesophagus are thought to be a...
Possible applications of high pressure for food preservation purposes or for changing the physical and functional properties of foods. The potentials and limitations of high pressure processing in food applications have become more clear. A number of key effects of high pressure on food components have been demonstrated including (i) microorganism inactivation (ii) modification of biopolymers including enzyme activation and inactivation, protein denaturation and gel formation (iii) quality retention (e.g. colour, flavour, nutrition value) and (iv) modification of physicochemical properties of water (Cheftel, 1991 Knorr, 1993). One of the unique characteristics of high pressure is that it directly affects non-covalent bonds (such as hydrogen, ionic, van der Waals and hydrophobic bonds) and very often leaves covalent bonds intact (Hayashi, 1989). As a consequence, it offers the possibility of retaining food quality attributes such as vitamins (Van den Broeck et al, 1998), pigments (Van...
Most food preservation and decontamination procedures, including irradiation, cause some loss in the nutritional value of foods. Further losses generally occur during storage and during preparation for consumption (e.g. in cooking). The specific chemical changes brought about in foods by irradiation include some that alter the nutritional value, but the magnitudes of the changes are small when compared with those that result from other procedures currently in use. This has led most expert groups to conclude that reduction in the nutritional quality of foods resulting from the widespread use of irradiation is an insignificant part of the total diet as a whole (Elias and Cohln 1977 Advisory Committee on Irradiated and Novel Foods, 1986). One expert group concluded that 'irradiation of food introduces no special nutritional problems' (World Health Organization, 1981). This conclusion emphasises the word 'special', recognising that there might be particular problems with some individual...
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.
We would like to point out that the relatively fewer food items (n 45) in our study questionnaire (compared with the usual 120 to 160 food items listed on validated food questionnaires for Western populations) was a reflection of the limited choices available to residents of China until the late 1980s. In fact, protein-rich foods such as meat, fish, eggs, and milk were rationed in China from the 1950s through the 1970s. At the time of our cohort accrual, only warm water fish were commonly available in Shanghai. The three seafood items (fresh fish, salted fish, and shellfish) listed in the study questionnaire encompassed all commonly available seafood in Shanghai in the early 1980s.
Avoid salt-cured, smoked, and nitrite-cured foods. These foods, which are also high in fat, include anchovies, bacon, corned beef, dried chipped beef, herring, pastrami, processed lunch meats such as bologna and hot dogs, sausage such as salami and pepperoni, and smoked meats and cheeses. Conventionally smoked meats and fish contain tars that are thought to be carcinogenic due to the smoking process. Nitrites are also thought to be carcinogenic.
Among the three seafood items specifically listed in the questionnaire, fresh fish (86.3 g per week) accounted for 67 of total seafood consumption shellfish (38.6 g per week) and salted fish (4.2 g per day) represented 30 and 3 , respectively. In analyses conducted separately for fish and shellfish, the inverse associations with acute MI were statistically significant for both fresh salted fish intake and shellfish intake (P for trend 0.02 in both instances Table 2.2).
High pressure technology is unlikely to replace conventional thermal processing, because the second technique is a well-established and relatively cheap food preservation method. Currently, the reported cost range of high pressure processes is 0.1-0.2 per litre (Grant et al, 2000) whereas the cost for thermal treatment may be as low as 0.02-0.04 per litre. However, the technology offers commercially feasible alternatives for conventional heating in the case of novel food products with improved functional properties which cannot be attained by conventional heating.
Burned or darkly browned foods, such as heavily roasted or barbecued meats Nitrites and nitrates (food preservatives used to give processed meats a pink color) Pesticides and other agrochemicals Regular heavy alcohol intake Processed meats (such as sausages, luncheon meats, smoked, pickled, or salt-cured meats) Rancid (oxidized) fats, such as fat used repeatedly for deep-fatfrying Old, mouldy foods particularly potatoes, peanuts, mushrooms, sprouts Artificial food dyes Heavily chlorinated drinking water
In general, plants are more concentrated sources of nickel than are animal sources. Nuts are the most concentrated sources while grains, cured meats, and vegetables offer respectable amounts. Fish, milk, and eggs are recognized as poorer sources of nickel. The absorption of nickel from the digestive tract is probably affected by varying the amounts of copper, iron, and zinc, and perhaps vice versa. Adult requirements for nickel are most likely about 35 micrograms daily although the RDA has yet to be established.
Salt noun 1. a substance consisting of small white tangy-tasting crystals, consisting mainly of sodium chloride, used for flavouring and preserving food 2. any crystalline compound formed from the neutralisation of an acid by a base containing a metal adjective 1. containing common salt 2. cured or preserved or seasoned with salt verb 1. to add salt to food 2. to preserve food by keeping it in salt or in salt water
Consequently, food irradiation is a tool that supplements traditional methods of food preservation it has already found its niche application. The total volume of goods treated is still small, estimated at about 200 000 tonne per annum, one half of which is spices and dry seasonings. Official statistics are unavailable for other methods such as canning, cooling and freezing. As the development in the US clearly demonstrates, the industrial implementation of radiation processing and its acceptance by the consumer come at the time when awareness for such needs has been established and the product is clearly labelled. This means that a slow but steady growth of the amount of irradiated food is to be expected.
For example, most Americans skimp on breakfast during the week, yet on Saturdays and Sundays they stuff themselves with smoked meat, fried potatoes, muffins, French toast, and maple syrup. Lunch usually consists of something appealing sandwiched between two slices of bread, accompanied by a soft drink. Dinner menus are decided by the family cook, a fast food restaurant, or the manufacturer of frozen meals.
The food frequency questionnaire listed three seafood items (fresh fish, salted fish, and shellfish). The commonly eaten fresh fish in Shanghai include carp, beam, and pomfret. The common species of salted fish consumed in Shanghai are yellow croaker and hairtail. Similarly, the common shellfish in Shanghai are shrimp and crab. The standard portion weight (without bone) for fresh fish was determined to be 46.8 g. The corresponding figures for salted fish and shellfish were 25.9 g and 43.3 g, respectively. We calculated the average daily intake of fish and shellfish per subject by summing over the three seafood items the cross-products of intake frequency and standard portion weight. The daily intake of n-3 fatty acids from fish and shellfish was estimated by multiplying the daily amount of each seafood item with the corresponding marine n-3 fatty acid content 11 fresh fish, 0.57 g per 100 g salted fish, 0.44 g per 100 g and shellfish, 0.36 g per 100 g. Warm water fish from the South...
Different regions of China have distinct tastes in food. Shang-hainese cooking is known for its spicy chili flavoring and trademark red-colored meats. The Cantonese and Chaozhao regions are known for cooked meats and vegetables and in the Beijing, Mandarin, and Shandong regions steamed bread and noodles are used as staples instead of rice. The most prized food staples in China are rice and wheat, though yams, taros, and potatoes are eaten when rice and wheat are not available. Chinese vegetables are mostly imported from Central Asia, including cucumbers, coriander, peas, sesame, onions, grapes and pomegranates, tomatoes, maize, sweet potatoes, peanuts, mushrooms, and daikon (radish). Preserved foods are popular, including pickled foods, fermented vegetables, and smoked and salted meats. Other well-known seasonings that are used include salted black beans (douchi), sweet and salty sauce, garlic, oyster sauce, soy sauce, black fungus, chilies, hoisin sauce, ginger, sesame seeds,...
