Snack on this: A nutritionist's perspective
As a practicing dietician in Chapel Hill, North Carolina, Kenlyn Young has a lot of advice for athletes who depend on good nutritional practices for optimal performance. Snacking is an integral part of an athlete's diet, if done right. Here is some advice from Young for best snacking habits for an athlete.
"The goal of eating pre-exercise is to ensure the body has adequate energy for best performance and also to ensure that blood sugar levels don't fall causing weakness, dizziness, or fatigue. Carbohydrates are the body's main fuel source and provide quick energy for our muscles. Great snacks to serve this purpose include 100% fruit juice, a piece of fruit (best choices bananas, fresh pineapple or dried apricots), pretzels, popcorn, or a granola bar. Avoid snacks high in processed sugar, fat, and protein for your pre-exercise snack. The no-no snacks include chips, cookies, donuts, etc.
After exercise, it is important to replenish and repair our muscles. The best snack for post-exercise contains both a carbohydrate and a protein. Great choices include cheese and crackers, apple with peanut butter, yogurt with granola, carrots with hummus, almonds and raisins, even chocolate milk."
