JENNIE BRAND-MILLER: I think it's good for everybody. And I say that because so many of us are struggling to maintain our weight. Lots of us have this sort of incremental weight gain creep as we get older. And one kilogram or two pounds a year doesn't sound like much. But you multiply it by 10 years and 20 years, then it's a struggle. So what low-glycemic index foods offer us is a slower rate of digestion of the carbohydrates in those foods. So they spend longer inside the gastrointestinal tract before they are absorbed. And that feeling we can detect, that feeling of, we call it satiety. But it's just a feeling of satisfaction, a feeling of fullness, which means we're less likely to want another meal so soon or a snack so soon.
