Your guide to finding low GI foods to keep your blood sugar stable

Harvard Medical School’s Healthbeat explains that the glycemic index (GI) of a food is a measure of how a specific food with carbohydrates causes blood sugar to rise. It is given as a number compared to the effect on your blood sugar of eating either glucose (a type of sugar) or white bread, according to research published in the journal Diabetes Care.

When you eat a food or beverage containing carbohydrates, your body breaks down the carbs into a type of sugar called glucose. The glucose goes into your bloodstream and causes your blood glucose (blood sugar) levels to rise, according to the Centers for Disease Control and Prevention.

Compared to low-glycemic foods, high-glycemic foods lead to a quicker and greater spike in blood sugar levels. These spikes are considered unhealthy for a few reasons.

  • They raise your average blood glucose levels
  • They place a higher demand for insulin on your body
  • They lead to more dramatic dips in blood glucose after the spike, potentially causing hunger, carbohydrate cravings, and weakness

A low-GI diet and meal plan can help you avoid the blood sugar roller coaster, but the GI is not on the nutrition label of most foods. Instead, you will probably to look at a list of the GI of foods.

Low glycemic index foods are often less processed, and higher in protein, fiber, fat, and/or complex rather than refined carbohydrates

According to the Linus Pauling Institute, here is a list of low glycemic foods:

Glycemic Index and Diabetes

Can a low-GI diet lower blood sugar if you have prediabetes or diabetes?
Probably, if you choose wisely. Low-GI foods are less likely to cause blood sugar spikes, and more likely to keep blood sugar stable in healthier ranges. You can help control prediabetes or diabetes with a diet based on nutritious, low-GI foods such as vegetables, beans, low-fat dairy, and whole grains, along with healthy proteins and fats. However, a diet high in unhealthy fats, fried foods, and processed meat may be low-GI, but is not likely to lower blood sugar.

Low GI Food List


Peaches

Glycemic Index, Weight Loss, and Health

Can a low-GI diet help you lose weight? Yes, but only if you are careful. Any diet can help you lose weight if you use it to limit calories.

To lose weight on a low-GI diet:

  • Choose healthy, filling low-GI carbs, such as vegetables, beans, low-fat dairy, berries, and whole grains.
  • Include lean proteins, such as tofu, chicken, fish, and eggs, and healthy fats, such as nuts, avocados, and olive oil.
  • Include nutritious “no-GI” foods (lean proteins and healthy fats).
  • Limit low-nutrition high-GI foods such as sweets, sugary beverages, and refined starches. Beware of low-GI foods that are high-calorie and low-nutrition, such as pizza and ice cream.
Whole wheat kernels

Low-Glycemic Grains

  • Barley
  • Whole wheat kernels
  • All-bran and Fiber One cereals
  • Oat bran and rice bran cereals
  • Whole grain pasta

  • Whole-grain pumpernickel bread
  • Sourdough bread
  • Wheat tortilla

  • Lentils
  • Edamame and roasted soybeans
  • Hummus 
  • Bean dip
  • Tofu and soy-based meat substitutes 

Guessing the Glycemic Index

What if you do not know the glycemic index of a food? That could happen if food has not have been measured or if you do not have time to check its GI before you eat it.

You cannot know for sure, but the GI tends to be lower when:

  • It is less processed. Whole grains are often lower-GI than refined, whole fruit is lower-GI than fruit juice, and raw carrots are lower-GI than cooked.
  • It is higher in fiber, protein, and/or fat, and lower in sugar and refined starch.
  • It is raw. For example, raw carrots are lower-GI than cooked, and al dente pasta is lower-GI than well-cooked.
  • Ripeness. A soft, ripe banana has a higher-GI than a firmer, less ripe one.

When you cannot get the GI for a food, going with your gut is usually a smart choice. You cannot go wrong when you eat foods that you know are healthy, limit junk food, and keep portions in check.

Nuts

  • Peanuts
  • Nuts (walnuts, macadamias, hazelnuts, almonds, cashews, etc.)

Low-Glycemic May Not Mean Healthy (and Vice Versa)

The GI is only one way to assess a food. Lower-GI often means healthier, but not always. For example:
  • You can lower the GI of a slice of bread by spreading it with butter. That is not healthy!
  • Boiled potatoes are high-GI and French fries are lower, but fries are not healthy!
  • Oatmeal and pumpkin are high-GI, but they are rich in healthy antioxidants and fiber.

The Glycemic Diet


The glycemic diet is, as it sounds, a diet based on the GI. Following a low GI diet means that when you eat foods with carbohydrates, you select those foods with a low GI. There are several potential benefits of a low GI diet.

  • Weight loss: When you choose lower-GI foods, you may be getting more fiber, fat, and protein compared to fast-acting carbs such as sugars and refined starches. The result may be that you feel full for longer after you eat, so you tend to eat less at your next meal. That can help you lose weight.
  • Better energy: A lower-GI diet means fewer and less dramatic spikes in blood sugar. At the same time, you do not get the subsequent dramatic drops in blood sugar and energy levels. This means your energy levels are more stable, and you may feel better.
  • Lower blood sugar: Your blood sugar does not spike as much, and the response demands less insulin, when you choose low-GI foods. Better blood sugar control is especially good news if you have prediabetes or diabetes.
  • Cardiovascular benefits: Lower-glycemic carbs tend to have more heart-healthy nutrients, such as fiber, which lowers cholesterol, and potassium, which lowers blood pressure. Plus, limiting simple sugars may help keep blood triglycerides in check.
