Here are nine scientifically proven health benefits of blueberries.

1. Rich in Nutrients

Like most berries, blueberries are a nutrient-dense fruit.

Blueberries have a similar nutrient profile to blueberries ().

Accordingly, blueberries can be expected to contain about 85 calories, 15 grams of naturally occurring sugar, and 4 grams of fiber per 150-gram serving.

Output:

Blueberries are relatively low in calories but are a good source of water, fiber, manganese, and vitamins C and K.

2. Contains Beneficial Plant Compounds

Blueberries contain vitamin C and phenolic acids, and are a particularly good source of anthocyanins, powerful flavonoid antioxidants that give red, purple, and blue fruits and vegetables their characteristic color ( , ).

It is believed that it is thanks to the anthocyanins contained in blueberries that this berry is so beneficial for the health of women and men.

Output:

Berries are one of the best dietary sources of antioxidants. Blueberries are a particularly good source of anthocyanins, powerful antioxidants likely responsible for their health benefits.

3. May Improve Vision

Blueberries are most popular for their ability to improve eyesight, especially night vision.

Several small studies have investigated the effect of these berries on night vision, but concluded that this property is not supported by strong evidence ().

However, blueberries may benefit your eyesight in other ways.

One 2-year study in people with glaucoma, a disease that leads to gradual loss of vision, showed that daily intake of 120 mg of blueberry anthocyanins improved visual function by about 30%, while visual function worsened in the placebo group ().

Other studies show that taking 160–480 mg of blueberry extract powder daily can reduce dry eyes and other symptoms of eye fatigue associated with computer work ( , , ).

However, more research is needed to confirm these beneficial properties.

Output:

Blueberries can improve eyesight in people with glaucoma and reduce eye fatigue and dryness in people who work with computers. However, more research is needed in this area.

4. May Reduce Inflammation

Blueberries can help fight inflammation, which is thought to be the root cause of many diseases.

This effect may be partly due to the anthocyanins it contains, which are antioxidants with anti-inflammatory properties ().

In one 3-week study, people taking a daily supplement containing 300 mg of blueberry anthocyanins experienced a 38–60% reduction in inflammatory markers compared to a 4–6% reduction in the placebo group ().

What's more, a small 4-week study found that drinking 330 ml of blueberry juice daily significantly reduced markers of inflammation compared to placebo ().

However, more research is needed to confirm these effects.

Output:

Blueberries are rich in anthocyanins, which are antioxidants that can reduce markers of inflammation.

5. May Lower Blood Sugar

Blueberries are a popular herbal remedy used to lower blood sugar levels in people with type 2 diabetes ().

Experts believe that berries prevent the breakdown and absorption of carbohydrates in the intestines, similar to some drugs that lower blood sugar levels ().

Animal studies show that the anthocyanins in blueberries can also stimulate the secretion of insulin, the hormone needed to move sugar from the blood into your cells ().

One study reported that blueberry extract lowered blood sugar levels in adults with type 2 diabetes more effectively than placebo. This amount of extract is the equivalent of 50 grams of fresh blueberries ().

Another 8-week study showed that a diet enriched with fresh blueberries increased insulin secretion in adults with metabolic syndrome, a group of conditions that increase the risk of type 2 diabetes, stroke, and cardiovascular disease ().

However, more human studies are needed before conclusions can be drawn.

Output:

Blueberries can stimulate insulin secretion and prevent the breakdown of carbohydrates in the intestines, which can help lower blood sugar levels. However, more human studies are needed.

6. May Improve Heart Health

Blueberries can benefit your heart.

This may be partly due to the fact that it is rich in vitamin K, which helps prevent blood clots, reducing the risk of heart attack and stroke ().

Test-tube studies also show that the specific blend of anthocyanins in blueberries can help lower blood pressure ().

In one 8-week study, 35 people who took a daily blend of different berries, including blueberries, experienced improvements in platelet function, blood pressure, and HDL (good) cholesterol levels - markers associated with a healthier heart ().

In another 12-week study, people taking 320 mg daily of blackcurrant and blueberry anthocyanins experienced an 11% increase in HDL (good) cholesterol as well as a 14% decrease in LDL (bad) cholesterol, compared with less than a 1% decrease in placebo group ().

However, more research is needed to confirm these effects.

Output:

Blueberries can help lower blood pressure, lower LDL (bad) cholesterol, increase HDL (good) cholesterol, and protect you from blood clots, thereby improving your heart health. However, more human studies are needed.

7–9. Other Potential Benefits

Blueberries may also have the following beneficial properties:

1. May improve brain function. Taking powdered blueberry supplements has been linked to improved long-term and working memory in older adults ().
2. Can kill bacteria. Test-tube studies show that blueberries may have antimicrobial activity against potentially harmful bacteria such as Salmonella and Staphylococcus aureus ( , ).
3. May relieve symptoms of ulcerative colitis (UC). A 13-person study found that taking a daily blueberry supplement reduced chronic inflammation of the colon and rectum in people with UC ().

Keep in mind that these studies were small and some lacked a placebo group, making it difficult to determine if blueberry supplements are causing the positive effects. Therefore, additional research is needed.

Output:

Blueberries may improve learning and memory in older adults, fight certain bacteria, and reduce symptoms of ulcerative colitis. However, more research is needed to confirm these effects.

How to include blueberries in your diet

Although blueberry leaf tea is sometimes used as an herbal remedy, the leaves are considered poisonous and experts do not recommend them for this use ().

The limited number of studies and large differences in dosage make it difficult to determine the most effective dose. However, most human studies have used anywhere from 50 grams of fresh blueberries to 500 mg of blueberry supplements.

Output:

Fresh blueberries are generally considered safe, but high doses in some supplements can cause problems. Children, adults taking certain medications, and pregnant and breastfeeding women may need to avoid blueberry supplements.
