Do athletes have special nutrient needs?
Increased physical activity increases some of your food needs. You require more energy, water, and possibly salt (sodium chloride). An athletic teenage boy may need 5,000 calories a day, compared to the 3,000 calories required daily by his nonathletic friends. By taking extra servings of foods from all food groups (particularly breads, cereals, vegetables, and fruits), you can fill this increased energy need.
