In briefThe most useful way to classify carbohydrate food for active people is by its ability to raise blood glucose concentration. To hasten recovery after intense training, athletes should consume at least 50 g of high- or moderate-glycemic carbohydrates as soon after exercise as is practical. They should eat at least an additional 50 g every 2 hours until they eat a large meal. To obtain the recommended 70% of calories from carbohydrate, athletes may find it helpful to determine how many 50-g carbohydrate food portions they need to eat daily.
