Whether you buy them fresh or frozen, blueberries are a sweet and delicious treat. If you haven’t added this superfood to your diet yet, you're missing out on a nutritional punch.

Blueberries range in color from dark blue to purple. The fruit gets its color from flavonoids called anthocyanins, which have antioxidant power to protect your body from damage and disease. Antioxidants also reduce inflammation in the body.

Are blueberries nutritious? The short answer is yes. They contain nutrients to improve your overall health, whether you’re trying to control your blood sugar or manage your weight. Here are a few health benefits of blueberries, plus tips on how to incorporate blueberries into your meals and snacks.

The nutritious benefits of blueberries

1. Good source of fiber

Fiber can get rid of constipation, plus control your weight, cholesterol levels, and blood sugar. This is a major plus if you're living with type 1 or type 2 diabetes.

One study found that eating three servings of blueberries (in combination with other whole fruits) per week could reduce the risk of type 2 diabetes by 7 percent.

One cup of blueberries has about 3.6 grams of fiber. Eating a couple of handfuls per day can help satisfy your daily fiber goal of 21 to 25 grams for women and 30 to 38 grams for men.

2. Low in fat and calories

If you're looking for a healthy snack during the day, blueberries are one of the best foods of choice. A single cup has only 84 calories and almost no fat. This means you can satisfy your sweet tooth without packing on the pounds.

3. Good source of vitamin C

Blueberries contain vitamin C, which also functions as an antioxidant. Vitamin C helps strengthen your immune system and wards off a variety of illnesses, including colds, urinary tract infections, and cancer. Vitamin C also contributes to healthy gums and improves the production of collagen for healthier and smoother skin. Other vitamins found in blueberries include:

  • vitamin A
  • vitamin K
  • vitamin B-6
  • folate

4. Blueberries protect against heart disease

Blueberries are sodium-free and cholesterol-free. Eating blueberries can naturally decrease blood pressure and lower the risk of heart disease and stroke. That’s because this fruit is an excellent source of potassium, calcium, and magnesium.

One study found that eating three or more servings of blueberries and strawberries per week might help women reduce their risk of a heart attack by as much as one-third.

5. Blueberries improve your mental health

Adding blueberries to your diet may reduce the risk of cognitive decline. A report published in the journal Annals of Neurology found that a higher intake of berry flavonoids appears to reduce rates of cognitive decline in older adults.

A preliminary study by the University of Cincinnati also found that eating blueberries daily could improve memory.

6. Promote stronger bones

Weak bones increase your risk of fractures. But eating blueberries may provide protection. A study in laboratory rats found that blueberries have substances that contribute to healthier, stronger bones.

The findings may have something to do with blueberries containing minerals that promote bone strength, including:

  • manganese
  • copper
  • iron
  • zinc
  • potassium
