8 Best Ways Blueberries Benefit Your Health

Those freshly-picked sweet blueberries are not only delicious but also nutritious. These exotic berries are low in calories and often termed as a superfood. This popular summer treat is rich in antioxidants and said to possess anti-inflammatory properties.

Consuming them may help reduce cancer risk, improve cardiovascular health, and lower blood pressure.

Should you include blueberries in your diet? Most definitely. In this article, we explore the health benefits of blueberries, their nutrition profile, and the risks associated with eating them. Keep reading!

8 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).

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 this 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.

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.

El √°rbol es originario de los tr√≥picos de Am√©rica y se cultivaba en M√©xico varios siglos antes de su aparici√≥n en las culturas cl√°sicas mesoamericanas. Or√≠genes geogr√°ficos de la papaya Es originaria del sur de M√©xico, Am√©rica Central y el norte de Am√©rica del Sur. Hoy en d√≠a se cultiva en la mayor√≠a de los pa√≠ses con clima tropical como Brasil, India, Sud√°frica, Sri Lanka y Filipinas.

Bayas

Recomiendo una porci√≥n diaria de  bayas  (media taza fresca o congelada, o un cuarto de taza seca) y tres porciones diarias de otras frutas (una fruta de tama√Īo mediano, una fruta cortada en taza, o un cuarto de taza seca).  ¿Por qu√© selecciono las bayas? Ar√°ndano Frambuesa Fresa Grosella Espinosa Grosella Negra Grosella Roja Baya de Acai Baya de Gota B√©rbero Las bayas son las frutas m√°s saludables, debido en parte a sus pigmentos vegetales. Evolucionaron para tener colores brillantes y contrastantes que atraen a las criaturas que comen frutas para ayudar a dispersar sus semillas, y las mismas caracter√≠sticas moleculares que dan a las bayas esos colores tan vibrantes pueden explicar algunas de sus capacidades antioxidantes. Las bayas est√°n en segundo lugar, despu√©s de las hierbas y las especias, como la categor√≠a de alimentos con mayor contenido de antioxidantes. Como grupo, tienen un promedio de casi 10 veces m√°s antioxidantes que otras frutas y verduras, y superan 50 veces m√°s que lo
