What kind of food should I take to prevent or treat a low blood sugar during exercise?
It may be necessary to eat a carbohydrate-containing snack (PDF) to prevent a low blood sugar. Ideally, the snack should be a liquid or readily absorbed form of simple carbohydrate. Remember that complex carbohydrate takes a longer time to digest. If the food is high fat or oily, the stomach will empty more slowly and the absorption of the sugar is delayed. High-fat or complex carbohydrate containing snacks may increase the risk of exercise-related low blood sugars.
