What Is Glycemic Index (GI)?
- The glycemic index (GI) is a ranking of carbohydrates on a scale from 0 to 100 according to the extent to which they raise blood sugar levels after eating.
- Foods with a high GI are those which are rapidly digested and absorbed and result in marked fluctuations in blood sugar levels.
- Low-GI foods, by virtue of their slow digestion and absorption, produce gradual rises in blood sugar and insulin levels, and have proven benefits for health.
- Low GI diets have been shown to improve both glucose and lipid levels in people with diabetes (type 1 and type 2).
- They have benefits for weight control because they help to control appetite and delay hunger. Low GI diets also reduce insulin levels and insulin resistance.
