Is it ok for diabetics to eat blueberries?
Quick Answer
Yes
Blueberries are not only safe for diabetics to eat, but they can also be beneficial. They are low in carbohydrates, which means they won’t significantly affect blood sugar levels. Additionally, blueberries are high in fiber and antioxidants, which can help manage diabetes.

What Is It?
Blueberries are a sweet, nutritious fruit that are low in calories and incredibly good for you. They are among the most nutrient-dense berries, containing fiber, vitamin C, vitamin K, and manganese.
Why It Can Be Risky
While blueberries are generally safe and healthy for diabetics, it’s important to consume them in moderation. Eating too many can still raise blood sugar levels, especially if they’re consumed with other high-carb foods.
- Potential spike in blood sugar levels if consumed in large quantities
- Possible interactions with diabetes medications if consumed in excess
Safe Method?
The best way for diabetics to eat blueberries is in their natural, raw state. Avoid blueberries in syrup or canned blueberries, as these often contain added sugars. Also, try to incorporate them into meals that also contain protein and fat to help balance blood sugar levels.
Can You Just Cut It Off?
A safe serving size for diabetics is about 1/2 to 1 cup of fresh blueberries.
Safe Alternatives
- Raspberries, which are also low in carbohydrates and high in fiber
- Strawberries, which are similarly low in sugar and high in antioxidants
- Blackberries, which are high in fiber and vitamin C
Storage Tips
Store fresh blueberries in the refrigerator to keep them fresh longer. Do not wash them until you’re ready to eat them, as moisture can cause them to spoil faster.
Preparation Tips
Blueberries can be enjoyed raw, added to salads, mixed into yogurt or oatmeal, or used in baking. Just be mindful of the added sugars in some recipes.
