New scientific consensus cites protection against heart disease and diabetes.
September 2013 — If youve heard of the glycemic index (GI for short) but arent quite sure whether you need to pay attention to itor exactly what it meansyoure hardly alone. Scientists have been debating the merits of measuring the glycemic index since its introduction in 1981. The glycemic index uses a 100-point scale to measure how rapidly the carbohydrates in a food cause blood sugar to rise. Glycemic load (GL) adjusts this figure by taking into account serving sizes and the amount of carbohydrates per serving.
