The fluctuation of blood sugar (red) and the sugar-lowering hormone insulin (blue) in humans during the course of a day with three meals. One of the effects of a sugar-rich vs a starch-rich meal is highlighted. [1] The blood sugar level, blood sugar concentration, blood glucose level, or glycemia is the measure of glucose concentrated in the blood.
A diet program that manages the glycemic load aims to avoid sustained blood-sugar spikes and can help avoid onset of type 2 diabetes. [6] For diabetics, glycemic load is a highly recommended tool for managing blood sugar. The data on GI and GL listed in this article is from the University of Sydney (Human Nutrition Unit) GI database. [7]
A diabetic diet is a diet that is used by people with diabetes mellitus or high blood sugar to minimize symptoms and dangerous complications of long-term elevations in blood sugar (i.e.: cardiovascular disease, kidney disease, obesity).
Apples. The original source of sweetness for many of the early settlers in the United States, the sugar from an apple comes with a healthy dose of fiber.
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.

Method of glucose uptake differs throughout tissues depending on two factors; the metabolic needs of the tissue and availability of glucose.The two ways in which glucose uptake can take place are facilitated diffusion (a passive process) and secondary active transport (an active process which on the ion-gradient which is established through the hydrolysis of ATP, known as primary active ...
In the event of low glucose concentration in the blood, most other tissues have alternative fuel sources besides ketone bodies and glucose (such as fatty acids), but studies have indicated that the brain has an obligatory requirement for some glucose. [13] After strict fasting for 3 days, the brain gets 25% of its energy from ketone bodies. [14]
Animal-derived foods that are high in fat and protein are generally AGE-rich and are prone to further AGE formation during cooking. [3] However, only low molecular weight AGEs are absorbed through diet, and vegetarians have been found to have higher concentrations of overall AGEs compared to non-vegetarians. [ 4 ]
