Adolescents tend to eat differently than they did as children. With after-school activities and active social lives, teens are not always able to sit down for three meals a day. Busy schedules may lead to meal skipping, snacking throughout the day, and more eating away from home. Many teens skip breakfast, for example, but this meal is particularly important for getting enough energy to make it through the day, and it may even lead to better academic performance. When teens skip meals, they are more likely to grab fast food from a restaurant, vending machine, or convenience store. These foods are high in fat and sugar and tend to provide little nutritional value. In addition, eating too many fast foods can lead to weight gain and, in some cases, diabetes and heart disease.

Dietary decisions made in adolescence may have lasting health effects. For example, in the United States, more than 85 percent of teen girls and about 65 percent of teen boys do not include enough calcium in their diets. Such deficiency increases their chances of developing osteoporosis as adults. [AP/Wide World Photos. Reproduced by permission.]
Eating meals and snacking away from home puts the responsibility for good food choices right in adolescents' hands. Snacks should be low in both fat and added sugar. Some healthful snack ideas include fresh fruit, sliced vegetables with low-fat dip, low-fat yogurt, low-fat string cheese, peanut butter and crackers, baked chips, granola bars, and graham crackers. Juices, fruit drinks, and sodas are usually very high in calories from natural or added sugar, so they should be consumed in moderation. The Food Guide Pyramid is an appropriate guide for adolescents' food choices, even when snacking.
