Processing:В Grains that have been milled and refined-removing the bran and the germ-have a higher glycemic index than minimally processed whole grains.

Many factors can affect a foodвЂ™s glycemic index, including the following:

The University of Sydney in Australia maintains a searchable database of foods and their corresponding glycemic indices.

A 2014 review of studies researching carbohydrate quality and chronic disease risk showed that low-glycemic-index diets may offer anti-inflammatory benefits.

Foods with a low glycemic index have been shown to help control type 2 diabetes and improve weight loss.

There is also preliminary work linking high-glycemic diets to age-related macular degeneration, ( 8) ovulatory infertility, ( 9) and colorectal cancer.

Eating many high-glycemic-index foods вЂ“ which cause powerful spikes in blood sugar вЂ“ can lead to an increased risk for type 2 diabetes, ( 2) heart disease, ( 3), ( 4) and overweight, ( 5, 6) ( 7).

Medium-level foods have a glycemic index of 56-69.

Low-glycemic foods have a rating of 55 or less, and foods rated 70-100 are considered high-glycemic foods.

Foods with a low glycemic index, like whole oats, are digested more slowly, prompting a more gradual rise in blood sugar. Foods with a high glycemic index, like white bread, are rapidly digested and cause substantial fluctuations in blood sugar. The glycemic index ranks carbohydrates on a scale from 0 to 100 based on how quickly and how much they raise blood sugar levels after eating. To explain how different kinds of carbohydrate-rich foods directly affect blood sugar, the glycemic index was developed and is considered a better way of categorizing carbohydrates, especially starchy foods. But other so called complex carbohydrate foods such as white bread and white potatoes contain mostly starch but little fiber or other beneficial nutrients.Дividing carbohydrates into simple and complex, however, does not account for the effect of carbohydrates on blood sugar and chronic diseases. Many complex carbohydrate foods contain fiber, vitamins and minerals, and they take longer to digest вЂ“ which means they have less of an immediate impact on blood sugar, causing it to rise more slowly.

These carbohydrates have more complex chemical structures, with three or more sugars linked together (known as oligosaccharides and polysaccharides). Simple carbohydrates are easily and quickly utilized for energy by the body because of their simple chemical structure, often leading to a faster rise in blood sugar and insulin secretion from the pancreas вЂ“ which can have negative health effects. These carbohydrates are composed of sugars (such as fructose and glucose) which have simple chemical structures composed of only one sugar (monosaccharides) or two sugars (disaccharides). In the past, carbohydrates were commonly classified as being either вЂњsimpleвЂќ or вЂњcomplex,вЂќ and described as follows: Over time, the heavy demands made on the insulin-making cells wears them out, and insulin production eventually stops. This condition, known as insulin resistance, causes blood sugar and insulin levels to stay high long after eating.

Type 2 diabetes usually develops gradually over a number of years, beginning when muscle and other cells stop responding to insulin.This interplay of insulin and glucagon ensure that cells throughout the body, and especially in the brain, have a steady supply of blood sugar.Д¬arbohydrate metabolism is important in the development of type 2 diabetes, which occurs when the body canвЂ™t make enough insulin or canвЂ™t properly use the insulin it makes.When this happens, the pancreas start making glucagon, a hormone that signals the liver to start releasing stored sugar.As cells absorb blood sugar, levels in the bloodstream begin to fall.As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage.When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood.
