Q: We were wondering what foods we should eat before and after exercising?


A: The when to eat also effects what to eat. It is best to eat more than 2 hours, but less than 4 hours before exercise. When a person chooses to eat after exercise is a personal choice.

A balanced diet of all 6 food groups from the Food Guide Pyramid would be OK to eat 2 - 4 hours before exercising. High fat or high sugar foods would not be recommended nor would a large meal be a good idea. Blood pools around your stomach and intestines for up to 2 hours after a meal, helping your body digest and absorb the nutrients from the food you ate. During that time, there is less blood in your legs and arms to power physical activities. Large meals can also make you feel sleepy. Have you ever felt tired after eating a big meal, especially one with turkey?

Your body prefers to run on the sugar in your blood (glucose). Carbohydrates like bread, potatoes, pasta, rice, cereal, crackers (starch), fruit or fruit juice are good foods to eat before exercise as they quickly break down into glucose. After exercise, carbohydrates quickly replace glucose your body used during exercise.

Another important food to eat before and during exercise is water. Read the fluids topic for more information.
