Glycemic index versus glycemic load -
Rather, diets that are too high or too low in carbohydrates can be problematic. Eating carbohydrates in the form of whole foods, such as whole grains, legumes, fruits, and vegetables, is better for your health than the carbohydrates contained in processed foods. Overall, research shows that eating a low glycemic load diet, especially one that is high in fiber and whole-grain foods, is considered beneficial for cardiovascular disease prevention and several other chronic diseases, such as type 2 diabetes.
One study, the PURE Prospective Urban Rural Epidemiology study, looked at how GI and GL impact cardiovascular health in nearly , people.
The PURE study found that higher GI and GL are associated with a greater risk of adverse cardiovascular disease events in adults with established cardiovascular disease. However, the study was limited by recall bias due to its observational study design.
More follow-up studies are needed to verify these results. Both of these tools are valuable in blood sugar management and diet planning. GI is more commonly discussed than GL, but both are integral to diet planning, whether you have diabetes or not.
Eating carbohydrates in moderation and exercising impact your body's ability to produce insulin and absorb glucose so those lifestyle choices must also be factored in. If you are trying to form a personalized diet plan, you may want to discuss the role of glycemic index and glycemic load in your food choices with a nutritionist or healthcare provider.
Glycemic index does not account for the many factors that impact your blood sugar, such as the amount of carbohydrates in a specific food and how quickly they are absorbed in the body.
This is why glycemic load is widely regarded as a more reliable tool than the glycemic index alone. Chickpeas, green leafy vegetables celery, kale, and spinach , carrots, and parsnips are the vegetables with the lowest glycemic load. The GI of pasta ranges from 40 to 60, which is the intermediate range.

Remember, by combining a low GI food with a high GI food, you will get an intermediate GI for that meal. The best carbohydrate food to eat varies depending on the person and situation.
For example, people with type 2 diabetes or impaired glucose tolerance have become resistant to the action of insulin or cannot produce insulin rapidly enough to match the release of glucose into the blood after eating carbohydrate-containing foods.
This means their blood glucose levels may rise above the level considered optimal. Now consider 2 common breakfast foods — cornflakes and porridge made from wholegrain oats. The rate at which porridge and cornflakes are broken down to glucose is different.
Porridge is digested to simple sugars much more slowly than cornflakes, so the body has a chance to respond with production of insulin, and the rise in blood glucose levels is less.
For this reason, porridge is a better choice of breakfast cereal than cornflakes for people with type 2 diabetes. It will also provide more sustained energy for people without diabetes. On the other hand, high GI foods can be beneficial at replenishing glycogen in the muscles after strenuous exercise.
For example, eating 5 jellybeans will help to raise blood glucose levels quickly. This page has been produced in consultation with and approved by:.

About the glycaemic index GI Foods and drinks provide our body with energy in the form of carbohydrates, fat , protein and alcohol. 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 2 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.
Glycaemic load GL The amount of the carbohydrate-containing food you eat affects your blood glucose levels. Calculating glycaemic load GL The GL calculation is: GI x the amount of carbohydrates in grams in a serving of food ÷ GI and exercise Eating low GI foods 2 hours before endurance events, such as long-distance running, may improve exercise capacity.
