Diabetes and Glycemic Index



Diabetes is a chronic disease that causes blood sugar levels to rise higher than average due to insulin resistance. Different foods have a different effect on the glucose (sugar) levels in the blood. One way to track blood sugar levels is to use the Glycemic index (GI) paired with carbohydrate counting. The GI measures how a carbohydrate-containing food raises glucose in the blood. According to the American Diabetics Association, the best foods are those low on the GI, and diabetic patients should stay away from the foods on the higher end.


Pairing foods significantly affect how the blood absorbs sugar. Pairing low GI foods with high GI foods can lower the foods’ GI on the higher end.


Below are examples of foods based on their GI:


Low GI Foods (55 or less)

100% stone-ground whole wheat or pumpernickel bread

Oatmeal (rolled or steel-cut), oat bran, muesli

Pasta, converted rice, barley, bulgar

Sweet potato, corn, yam, lima/butter beans, peas, legumes, and lentils

Most fruits, non-starchy vegetables and carrots, greens

Milk and yogurt

Quinoa

Bulgar, barley


Medium GI (56-69)

Whole wheat, rye, and pita bread

Quick oats

Brown, wild or basmati rice, couscous

Raisins

Potato Chips


High GI (70 or more)

White bread or bagel

Corn flakes, puffed rice, bran flakes, instant oatmeal

Short grain white rice, rice pasta, macaroni, and cheese from mix

Russet potato, pumpkin

Pretzels, rice cakes, popcorn, saltine crackers

melons and pineapple

Honey

Donuts

Sports drinks

Drawbacks

Although knowing the GI of the food you eat can help people better manage their diabetes and even lose weight, it has its downfalls. The GI index is based on 50g of carbohydrates, which varies in portion size depending on the food type. 50g for many foods is well out of the typical serving size. It also depends on the ripeness of the foods. A green banana will have a lower GI than a ripe one. Also, a low GI does not mean a food is healthy. Foods that have a low GI can sometimes have no nutritional value at all. Following the GI of nutrition and food pairing is an excellent way to determine how it will affect your blood sugar; however, it is not foolproof.
