What exactly is the glycemic index?

The glycemic index (GI) is a measurement of how much certain foods raise blood sugar levels.

Foods are classed as a low, medium, or high glycemic and are graded from 0 to 100.

The lower a food’s GI, the less it may affect your blood sugar levels (1Trusted Source).

The three GI ratings are as follows:

Low: 55 or lower

56–69 medium

70 degrees Fahrenheit or higher

Foods high in refined carbs and sugar are digested mor quickly and have a higher GI, whereas foods high in protein, fat, or fibre have a lower GI. Meat, fish, poultry, nuts, seeds, herbs, spices, and oils are examples of foods with a GI.

Other elements that influence a food’s GI include its ripeness, cooking style, sugar content, and amount of processing it has received (2Trusted Source).

Keep in mind that the glycemic index is not the same as the glycemic load (GL).

Unlike the GI, which does not include the quantity of food consumed, the GL considers the number of carbs in a portion of a food to evaluate how it may alter blood sugar levels (1Trusted Source).

As a result, when choosing meals to support healthy blood sugar levels, it’s critical to consider both the glycemic index (Gi) and the glycemic load (GL) are very important factos to consider when lpicking the right foods (1Trusted Source).

Low glycemic index diet

The low glycemic diet entails replacing items with a high GI with those with a lower GI.

Benefits

A low glycemic diet may have various health benefits, including:

Improved blood sugar control. A low GI diet has been shown in numerous trials to lower blood sugar levels and improve blood sugar management in persons with type 2 diabetes (3Trusted Source, 4Trusted Source).

Weight loss has increased. According to several studies, following a low GI diet may promote short-term weight loss. More extensive research is needed to assess its impact on long-term weight management (5Trusted Source, 6Trusted Source, 7Trusted Source).

Lowering cholesterol levels: A low GI diet may help lower total and LDL (harmful) cholesterol levels, which are risk factors for heart disease (8Trusted Source, 9Trusted Source).

How to Do It

A healthy, low glycemic diet should consist primarily of low GI foods, such as:

Apples, berries, oranges, lemons, limes, and grapefruit

Broccoli, cauliflower, carrots, spinach, and tomatoes are examples of non-starchy vegetables.

Quinoa, couscous, barley, buckwheat, farro, and oats are examples of whole grains.

Lentils, black beans, chickpeas, and kidney beans are examples of legumes.

Foods with low GI values can also be consumed as part of a well-balanced low glycemic diet. They are as follows:

Beef, bison, lamb, and pork

Tuna, salmon, shrimp, mackerel, anchovies, and sardines are examples of seafood.

Poultry includes chicken, turkey, duck, and goose.

Olive oil, coconut oil, avocado oil, and vegetable oil are some of the oils used.

Almonds, macadamia nuts, walnuts, and pistachios are examples of nuts.

Chia seeds, sesame seeds, hemp seeds, and flax seeds are examples of seeds.

Turmeric, black pepper, cumin, dill, basil, rosemary, and cinnamon are among the herbs and spices used.

Although no items are explicitly forbidden on a diet, foods having a high GI should be consumed in moderation.

The following foods have a high GI:

White bread, bagels, naan, and pita bread

Rice varieties include white rice, jasmine rice, and arborio rice.

Cereals include quick oats and breakfast cereals.

Pasta and noodle dishes include lasagna, spaghetti, ravioli, macaroni, and fettuccine.

Mashed potatoes, potatoes, and french fries are examples of starchy vegetables.

Cake, doughnuts, cookies, croissants, and muffins are examples of baked goods.

Chocolate, crackers, microwave popcorn, chips, and pretzels are some of the snacks available.

Soda, fruit juice, and sports drinks are examples of sugar-sweetened beverages.

Whenever possible, attempt to substitute these items with foods that have a lower GI.
