What Is Glycemic Index

Glycemic Index or GI Index is a  ranking of carbohydrates on a scale from 0 to 100 according to the extent to which they raise blood sugar levels. It  measures how much your blood glucose increases after eating. Low Glycemic Index index food (less than 55) produce small rise in blood sugar and insulin level. Foods with GI index between 55 and 70 are consider intermediate-GI foods. High Glycemic Index food GI numbers (more than 70) make our blood sugar and insulin levels rise fast.
