A low-glycemic diet is one that selects foods on the basis of minimal alteration of circulating glucose levels. Low glycemic index pdf is set at 100, and all foods are indexed against that number.
Low GI foods affect blood glucose and insulin levels less and have a slower rate of digestion and absorption. One example of a low-glycemic diet is the Glycemic Index Diet developed by David J. Jenkins, a professor of nutrition at the University of Toronto and, from 2002 onwards, turned into a successful line of diet books by author and former president of the Heart and Stroke Foundation of Ontario, Rick Gallop.
Switching from a high glycemic index diet to a low glycemic index diet is considered to be relatively easy. Switching from white bread and pastas to whole grain, from breakfast cereals to oats, bran or barley, adding more fruits and vegetables when cooking, and reducing potato consumption can all aid in lowering glycemic index.
