Are Berries Good for Diabetes and Prediabetes?

Clients and readers often ask me what fruits are good for diabetes or prediabetes. It’s really a simple answer: All of them! Every single fruit has a unique array of disease-fighting nutrients and phytonutrients like beta-carotene, lycopene, polyphenols and more. Research suggests that berries have something unique to offer.

In general, eating fruit is associated with less chronic disease, not more. And that includes heart disease, stroke, type 2 diabetes and some types of cancer. Yet many people fear fruit because of its carbohydrate content. Specifically, people worry about the sugar content of fruit. Those with diabetes or prediabetes are concerned because of what eating fruit might do to their blood sugar levels. But fruit is more than blood sugar-raising carbohydrate.

While it is true that carbohydrate raises blood sugar levels more than other nutrients, it is not true that fruit raises blood sugar more than other carb-containing foods. Foods are much more than their macronutrient – carbohydrate, protein and fat – content. Avoiding health-boosting foods because carbohydrate raises blood sugar is like throwing the baby out with the bathwater. Fruits, along with other plant foods, contain so many disease-fighting, insulin-sensitizing compounds that it’s a bad idea to forgo them.

How Fruit is Good for Diabetes and Prediabetes

Scientists aren’t fully clear about how various phytonutrients (aka phytochemicals) lower the risk for type 2 diabetes or help with blood sugar control. However, they likely act in the intestines to slow down glucose absorption and act in other areas of the body to affect glucose metabolism and to increase insulin sensitivity. They also interact with our gut microbes. And some probably act as antioxidants and anti-inflammatory compounds. These phytonutrients likely exert both short term and long term actions, so it’s smart to eat plant foods with each meal and snack.

We also get these important compounds in nuts, seeds, tea, coffee, vegetables and grains. They are in all of our plant foods. Scientists have identified thousands of phytonutrients, so a diet packed with a variety of plant foods of all types is critical for disease prevention.

Eat berries if you have prediabetes

A study in Finland found that middle aged and older men who consumed the most berries had a whopping 35% lower risk of developing type 2 diabetes. Other studies among men and women also link berries to less incidence of the disease.

The American Diabetes Association calls out berries as a good choice for people with prediabetes. They say that diets with higher intakes of berries, nuts, yogurt, coffee and tea are linked to less risk of type 2 diabetes.

Eat berries if you have diabetes

If berries are good for prediabetes, it’s not surprising that they’re also good for diabetes. The nutrients and phytonutrients in berries appear to limit glucose absorption and to help reduce insulin resistance, which is a hallmark of type 2 diabetes.

Eating berries looks to be good for the heart, as well.

Of course, if you have diabetes, count the carbs in your portion of fruit to stay within your target. Here’s what about 15 grams of carbohydrate looks like.

    Thank you for sharing such a useful piece of information, have you thought about drinking wine to prevent diabetes. According to Chinese researchers drinking a glass of wine or 16 ounces of brew every day may help avoid type 2 diabetes. The specialists found that drinking around 2.5 units daily could help improve glucose digestion.

      Thanks for asking about alcohol and type 2 diabetes prevention. Here’s an excerpt from my book Prediabetes: A Complete Guide. Consuming small amounts of alcohol is also linked to less type 2 diabetes. But alcohol in excess is linked to more, as well as many other problems. That’s why the American Diabetes Association and other organizations do not recommend drinking for the prevention of disease. If you do drink, you don’t need much. The benefits of drinking
      alcohol appear to occur with as little as one-half standard drink daily. Consuming alcohol in moderation is also associated with reduced risk of dying from heart disease. Alcohol might protect the heart by increasing HDL (good) cholesterol. Additionally, the phytonutrients and other antioxidant compounds in red wine may further benefit the heart by protecting the blood vessels from oxidative damage. Remember that moderate drinking is defined as no more than one drink daily for women and no more than two drinks daily for men. And the size of those drinks matters. What we pour ourselves or receive in bars and restaurants is often much more than a single standard drink (5 ounces wine, 12 ounces beer, 1.5 fluid ounces of 80-proof liquor and 1 fluid ounce of 100% proof liquor).

    will my glucose numbers go down if I eat more fiber?

    • Jill Weisenberger on August 13, 2021 at 12:06 pm

      Rick, it’s really more complicated than that. Fiber is beneficial for many reasons, and there are many types of fibers. Some do help manage blood glucose levels, but simply eating more fiber without taking your full diet into consideration wouldn’t be of much benefit. You will likely benefit from seeing a registered dietitian nutritionist who can help you create an individualized eating plan. Ask your doctor for a referral. Additionally, I have an eating guide for type 2 diabetes beginners
