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. [2]
Fructose (/ ˈ f r ʌ k t oʊ s,-oʊ z /), or fruit sugar, is a ketonic simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose.It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed by the gut directly into the blood of the portal vein during digestion.

Carbohydrate content of foods is listed on the Nutrition Facts panel as "total carbohydrate". Some food labels will list specific types of carbohydrate, such as "fiber, sugar, or other carbohydrate".
We've compiled the best and the worst fruits—the "worst" fruits are those that have a sugar content higher than 10 grams and more calories than others. Check out the slideshow above for the 10 ...
A raw apple is 86% water and 14% carbohydrates, with negligible content of fat and protein (table). A reference serving of a raw apple with skin weighing 100 g (3.5 oz) provides 52 calories and a moderate content of dietary fiber (table).

A food pyramid is a representation of the optimal number of servings to be eaten each day from each of the basic food groups. [2] The first pyramid was published in Sweden in 1974. [3] [4] [5] The 1992 pyramid introduced by the United States Department of Agriculture (USDA) was called the
The carbohydrate, protein and lipid content of plants is highly variable. Carbohydrates are mainly in the form of starch, fructose, glucose and other sugars. [36] Most vitamins are found from plant sources, with the exception of vitamin D and vitamin B 12. Minerals can also be plentiful or not.
Watermelon fruit is 91% water, contains 6% sugars, and is low in fat (table). [29] In a 100-gram (3 + 1 ⁄ 2-ounce) serving, watermelon fruit supplies 125 kilojoules (30 kilocalories) of food energy and low amounts of essential nutrients (see table). Only vitamin C is present in appreciable content at 10% of the Daily Value (table).
