But following meals, capillary and arterial blood glucose levels can be significantly higher than venous levels. Although these differences vary widely, one study found that following the consumption of 50 grams of glucose, "the mean capillary blood glucose concentration is higher than the mean venous blood glucose concentration by 35%."

Insulin, which lowers blood sugar, and glucagon, which raises it, are the most well known of the hormones involved, but more recent discoveries of other glucoregulatory hormones have expanded the understanding of this process. The gland called pancreas secretes two hormones and they are primarily responsible to regulate glucose levels in blood. [1]
At a basic level, blood sugar is balanced by eating a whole-foods diet primarily focused on lean protein, vegetables, and complex carbs, since these foods provide the most reliable and stable ...
The GI was invented in 1981 by Dr Thomas Wolever and Dr David Jenkins at the University of Toronto and is a measure of how quickly a food containing 25 or 50 g of carbohydrate raises blood-glucose levels. Because some foods typically have a low carbohydrate content, Harvard researchers created the GL, which takes into account the amount of ...
"Many foods and beverages can positively or negatively affect glucose levels," Dr. Gladd says. "For example, fiber-rich foods, such as vegetables and beans, slow sugar absorption and help keep ...
In general, the body controls how much glucose is in the blood relative to how much gets into the cells with two hormones: insulin and glucagon. Insulin is used to reduce blood glucose levels, and glucagon is used to increase blood glucose levels. Both of these hormones are produced by clusters of cells in the pancreas called islets of Langerhans.
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 ...
