The Glycemic Index is a tool that gives a numerical value to a specific amount of food based on how it affects your body’s blood sugar and insulin over a specific time period. Foods with lower numbers don’t spike blood sugar as much as ones with higher numbers and provide more sustained energy.
Why does this matter to dancers?
Dancers who eat foods low on the GI tend to have more sustained energy overtime and more endurance. Not only can low GI foods improve performance, but when eaten before exercise they can help you feel more satisfied and may even help you burn more fat. Whole grains, fruits, vegetables, beans, and peas are all considered good choices.
How to keep a low GI diet
Consider the importance of lowering the GI of your entire diet as a whole instead of picking out foods individually. Basically that means eat more whole foods. When low GI foods are consumed as part of an overall diet, there is a lower insulin response and better glucose control. A low GI diet as a whole helps you feel more satisfied after eating and leads to less overeating. It is also important to eat smaller more frequent meals for good blood sugar control, to feel great, and to dance stronger.
- The GI is a numerical index used to describe how a carbohydrate is metabolized/ absorbed and its effect on blood glucose and insulin levels.
- Consuming low GI carbs before endurance exercise results in increased fat oxidation during exercise in trained men and women.
- Participants in a J. Nutr study reported feeling full following lunch in a low GI trial.
- Consuming a low GI breakfast increases fat oxidation during exercise and improves satiety during recovery. (J. Nutr. 139: 890–897, 2009).
