FoodData Central is USDA's integrated data system that contains five types of data containing information on food and nutrient profiles: [2] Standard Reference, using earlier approaches to determining nutrient profiles of foods in the marketplace, provides a comprehensive list of values for nutrients and food components that are derived from calculations and analyses.
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. [2]
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.
“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 ...
GI is a measure of the effects of carbohydrates in food on blood sugar levels. It estimates how much each gram of available carbohydrate (total carbohydrate minus fiber) in a food raises a person's blood glucose level following consumption of the food, relative to consumption of glucose. Glucose has a glycemic index of 100, by definition, and ...

As foods vary by brands and stores, the figures should only be considered estimates, with more exact figures often included on product labels. For precise details about vitamins and mineral contents, the USDA source can be used. [1] To use the tables, click on "show" or "hide" at the far right for each food category.
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] The glycemic load of food is a number which estimates how much a food will raise a person's blood glucose level. [citation needed]
