Diet and Longevity
There is other huge advantage to using low glycemic foods besides weight control: longevity! According a study by T. Par entitled "Insulin Exposure and Aging Theory" in the Journal Gerontology - 1997; 43:182-200, high insulin levels, which result from consuming high glycemic foods, promotes accelerated aging. Both calorie restriction and a low glycemic index diet appear to be important for longevity, BUT a diet of low glycemic foods is even more effective than calorie restriction for longevity.
