JENNIE BRAND-MILLER: OK. So there's two main benefits of eating low GI. One of them is that those foods, carbohydrate foods, take longer to digest. And they go through the small intestine more slowly. They keep you feeling fuller, more satisfied. You're less likely to eat morning tea after a low GI breakfast because the food is kind of sitting there still. So that's one benefit that probably you'll eat less over the course of the whole day. And that spells good things for weight control. The second aspect is that those foods that are slowly digested and absorbed have much less effect on the blood glucose levels. They're more on even keel. Instead of being a roller coaster going up and down quickly, you've got this even keel. And that's good for the cells. It's good for the mitochondria inside the cells, the little furnaces that produce energy. All right. So a low-glycemic index diet makes you feel good.
