Graph depicting blood sugar change during a day with three meals. The glycemic (glycaemic) index (GI; / ɡ l aɪ ˈ s iː m ɪ k / [1]) is a number from 0 to 100 assigned to a food, with pure glucose arbitrarily given the value of 100, which represents the relative rise in the blood glucose level two hours after consuming that food.

Glycemic index is a ranking of how quickly food is metabolized into glucose when digested. It compares available carbohydrates gram-for-gram in foods to provide a numerical, evidence-based index of postprandial (post-meal) blood sugar level. The concept was introduced in 1981. [1]
A quick refresher: the glycemic index (GI) was created in the 1980s by David Jenkins, and measures how fast carbohydrates in food and drink raise your blood sugar on a scale of 1 to 100.
"Foods on the glycemic index (GI) are ranked in terms of how quickly they are digested and raise your blood sugar," explain The Nutrition Twins®, Tammy Lakatos Shames, RD, CDN, CFT, and Lyssie ...
The glycemic index is a ranking system that measures how quickly carbohydrate-containing foods raise blood sugar levels. Foods are scored from 0 to 100, with pure glucose, at 100, representing the ...
[1] [17] For type 2 diabetics, the focus of a vegetarian or vegan diet should be maintaining a level of caloric intake that results in fat loss, adequate protein consumption, adequate consumption of compounds that are most bio-available in animal products (i.e. vitamin B-12, iron, creatine), and whole food carbohydrate sources that are lower in ...
“The glycemic index is based on a system where foods are ranked zero to 100 according to how drastically they cause blood sugar to rise,” says Vandana Sheth, RDN, CDCES, a Los Angeles-based ...
The glycemic index was devised by Jenkins et al. at the University of Toronto as a way of conveniently classifying foods according to the way they affected blood sugar and was developed for diabetics suffering from diabetes mellitus. Montignac was the first to recommend using the glycemic index as a slimming diet rather than a way of managing ...
