Blueberries are a tasty tropical treat packed with nutrients. The immense health benefits of blueberries make them a perfect superfood. They are rich in antioxidants, contain little to no calories, and reduce inflammation risk.

Blueberries may also help lower blood pressure, reduce cancer risk, and improve cardiovascular health.

There are several other reasons to include blueberries in your diet. This article explores the rich nutrient profile of blueberries, their health benefits, and potential risks. Read on to learn more.

11 Science-Backed Benefits Of Blueberries

1. High In Antioxidants

Blueberries are high in antioxidants that prevent or delay cell damage. They contain plant chemicals like polyphenols and flavonoids, which may help prevent chronic diseases (1). A study conducted by Cornell University (USA) found that blueberries have high cellular antioxidant activity (CAA). Thus, consuming them may decrease oxidative stress (2). They also contain flavonoids like anthocyanins (a plant compound) that may help improve the vascular system and brain function (3), (4).

Another study suggests that increased intake of antioxidant-rich foods may reduce the risk of chronic degenerative diseases (5). Pterostilbene, another antioxidant component found in blueberries, may prevent inflammation and improve diabetes (6).

The natural color of ripe blueberries is a deep blue-purple, which is due to the presence of anthocyanins, the antioxidants responsible for their color.

2. May Help Reduce The Risk Of Cancer

The rich antioxidant profile of blueberries may help prevent carcinogenesis and cancer cell growth (7). They contain phytochemical compounds that protect the cells from chronic inflammation (8). However, sufficient human-based data is not available to prove this benefit of phytochemicals from fruits.

Consuming blueberries may also help reduce DNA damage (9). A study found that drinking blueberry juice for four weeks had a protective effect on oxidative DNA damage – a major cause of cancer (10). However, more studies need to be conducted in this area.

3. May Improve Cardiovascular Health

Research suggests that increased intake of anthocyanin-rich foods may help reduce the risk of heart attack in young women. People who ate blueberries thrice or more a week posed a lower risk in this regard (11). Consuming a cup of blueberries a day may also reduce the risk of cardiovascular diseases and improve heart function (12).

A study showed that eating wild blueberries for a month improves the vascular system (13). Another study conducted by the University of Arkansas (US)also found that blueberry intake may prevent cardiovascular diseases (14). However, more studies are required to prove this claim.

4. May Lower Blood Pressure

Consumption of blueberries can lower blood pressure effectively (13). A study suggests that daily blueberry intake may help reduce blood pressure and arterial stiffness (15). The minerals like calcium, potassium, and magnesium found in blueberries may also help reduce blood pressure (16).

Moreover, daily intake of blueberry powder for six weeks was found to reduce diastolic pressure (blood pressure in arteries) (17).

5. May Improve Cognitive Performance

Supplementation of blueberry may improve memory in older people (18). It may also prevent incidences of cognitive decline and reduce depression symptoms. A study conducted by the Brigham and Women’s Hospital (US) found that the high flavonoid content of blueberries may slow down the cognitive decline rate (19).

Berry fruits also have neuroprotective effects that help improve age-related neurodegenerative diseases and cognitive functions (20). Blueberry supplementation may also improve short-term memory conditions (21).

6. May Help Manage Diabetes

Blueberries are rich in bioactive compounds such as polyphenols. Including these compounds in your diet may lower the risk of type-2 diabetes (22).

The low glycemic index (meaning, they digest slowly) of blueberries is less likely to cause spikes in blood sugar (23). Moreover, a six-week dietary supplementation of freeze-dried whole blueberry powder was found to improve insulin sensitivity in obese and non-diabetic individuals (24).

Extracts of Canadian lowbush blueberries were also found to have anti-diabetic potential (25).

7. May Strengthen Bones

The vitamins and minerals in blueberries may help maintain bone health. They prevent the loss of collagen in the bone matrix (26). A review published in the Journal of the International Society of Sports Nutrition suggests that consuming blueberries may help in recovery from exercise-induced muscle damage (EIMD) (27). However, more studies are required to understand the benefit of blueberries in humans.

8. May Fight Urinary Tract Infections

The antibacterial effect of blueberries may help treat or prevent urinary tract infections (28). A study conducted by the University of Stirling (UK) found that drinking blueberry or cranberry juice may prevent symptomatic urinary tract infections (UTIs) (29). However, limited data is available in this regard.

9. May Improve Kidney Function

Adequate consumption of blueberries may have a positive effect on overall kidney function. A study done on animals with metabolic syndrome conditions has shown that the antioxidants from blueberries reduce oxidative stress and protect the kidney against inflammation-induced structural injury and the risk of dysfunction (30). Another study hypothesizes that berries such as blueberries, raspberries, strawberries, and cranberries are rich in polyphenols, which can potentially lower uremic toxin levels in the body through modulation of gut microbes (31). This may protect or help treat renal issues in patients with chronic kidney diseases in the long term. However, further research is required for more conclusive results.

10. May Boost Immune System

Blueberries are high in vitamin C, which strengthens the immune system and supports collagen production, a protein that keeps the skin firm and supple. Collagen is especially important for people who spend a lot of time in the sun as UV rays may break down collagen.

11. May Improve Digestion

Blueberries contain fiber, which helps to maintain the digestive system. Fiber is a type of carbohydrate that is not digested by humans. Instead, it passes through the body without being absorbed into the bloodstream.

Blueberries are considered to be a wonder fruit due to their impressive nutritional profile. In the next section, we discuss the nutritional breakdown of blueberries.
