For example, a past study found that when participants with poorly managed diabetes, who were on insulin or oral diabetes medications , followed a low-glycemic load diet for 10 weeks, they lost weight, lowered their cholesterol levels , and improved their A1C. Another small past randomized study found that low-glycemic-load foods, regardless of calorie restriction, was more helpful with weight loss than a diet rich in high-glycemic-load foods.
However, insulin secretion was needed to see the benefit.

Here is a glycemic load reference list with many common foods to let you know which are low, medium, and high, per UCSF.
Knowing the glycemic load of food is a helpful meal planning tool, but you shouldn't rely on this ranking system alone. Plus, various factors can change where a food ranks on the glycemic index. For example, some foods with carbs become easier to digest after a longer cooking time, which can subsequently raise their glycemic load, says the Canadian Society of Intestinal Research.
So while adding low glycemic load foods can help balance your glycemic response, focusing on overall dietary quality and promoting the healthful aspects of a diet may be a better approach to help reduce chronic disease, says Dr. By subscribing you agree to the Terms of Use and Privacy Policy.

The GI can be considered when choosing foods and drinks consistent with the Australian Guide to Healthy Eating , but there are limitations. For example, the GI of some everyday foods such as fruits, vegetables and cereals can be higher than foods to be eaten occasionally discretionary like biscuits and cakes.
This does not mean we should replace fruit, vegetables and cereals with discretionary choices, because the first are rich in important nutrients and antioxidants and the discretionary foods are not.
GI can be a useful concept in making good food substitution choices, such as having oats instead of cornflakes, or eating grainy bread instead of white bread. Usually, choosing the wholegrain or higher fibre option will also mean you are choosing the lower GI option. There is room in a healthy diet for moderate to high GI foods, and many of these foods can provide important sources of nutrients.

Summary Read the full fact sheet. On this page. Digesting and absorbing carbohydrates The digestive system breaks down carbohydrates in foods and drinks into simple sugars, mainly glucose. The glycaemic index GI The glycaemic index GI is a way of ranking carbohydrate-containing foods based on how slowly or quickly they are digested and increase blood glucose levels over a period of time — usually two hours.
These ranges, along with some example foods, include: low GI less than 55 — examples include soy products, beans, fruit, milk, pasta, grainy bread, porridge oats and lentils medium GI 55 to 70 — examples include orange juice, honey, basmati rice and wholemeal bread high GI greater than 70 — examples include potatoes, white bread and short-grain rice.
For instance, although both ripe and unripe bananas have a low GI less than 55 , an unripe banana may have a GI of 30, while a ripe banana has a GI of Fat and acid foods like vinegar, lemon juice or acidic fruit slow the rate at which the stomach empties and slow the rate of digestion, resulting in a lower GI.
Eating healthier carbohydrates can help prevent a host of chronic conditions, especially diabetes, but it can also ward off heart disease and various cancers. One way to choose foods is with the glycemic index GI.
This tool measures how much a food boosts blood sugar. The glycemic index rates the effect of a specific amount of a food on blood sugar compared with the same amount of pure glucose.
One with a GI of 95 acts like pure glucose. High glycemic foods result in a quick spike in insulin and blood sugar also known as blood glucose. Low glycemic foods have a slower, smaller effect. Using the glycemic index is easy: choose foods in the low GI category instead of those in the high GI category see below , and go easy on those in between.
