Pre-Game Healthy Sports Snacks
Help your child make it to half-time feeling strong: Fuel muscles with carbohydrates one to two hours before an athletic event or practice.
For a longer game or training session, add some protein or fiber to slow digestion and sustain energy. To get these, choose fruit or low-fat protein options such as milk, turkey, or yogurt. But skip snacks with lots of sugar.
Pre-game snacks to avoid include fatty foods, since these slow digestion, and extra-sweet foods such as soda, candy, and sports drinks. These cause a spike in blood sugar. If sugar levels rise and then drop quickly during a game, your child could become sluggish or even dizzy.
Easy pre-game snack suggestions:
1 Whole-grain bread, crackers, tortillas, or pretzels
2 Cereal (as long as it's not high in sugar)
3 Enriched pasta or brown rice
4 Plain popcorn
5 Low-fat cheese, milk, yogurt, or pudding
6 Turkey, chicken, tofu
7 Apples, bananas, pears, oranges
8 Carrots, sugar snap peas, cucumbers
