Blueberries are nutrient-dense, low in calories, and high in fiber. According to USDA National Nutrient Database, the berries are a rich source of vitamin C, vitamin K, vitamin B6, folate, potassium, copper, and manganese. They are low in and sodium and are high in water content.
They are also abundant in antioxidants, especially anthocyanin, which is responsible for their deep blue color and powerful health benefits. Blueberries have the highest amount of antioxidants in them compared to all the foods!
Let’s take a look at the powerful health benefits of blueberries.
Blueberries are rich in calcium, iron, magnesium, phosphorous, manganese, zinc, and vitamin K, which help improve bone health. They also increase bone density and elasticity and contribute to maintaining the bone structure.
Anthocyanin in blueberries is responsible for preventing oxidative DNA damage, while the abundance of vitamin C is a big factor in building collagen. This is why they prevent wrinkles, age spots, and acne. Additionally, they also prevent skin damage caused by dust, pollution, smoke, and UV rays.
Lower Bad Cholesterol
Research suggests that the high fiber content and abundant antioxidants in blueberries help dissolve the LDL (bad) cholesterol. This makes them an ideal dietary supplement to combat many heart diseases, while also strengthening the cardiac muscles. They also contain potassium, calcium, and magnesium, which help in reducing blood pressure.
A study conducted by Dr. Arturo Figueroa, Kinesiology and Sports Management, Texas Tech University, US, shows that daily consumption of blueberries helps improve blood pressure and arterial stiffness in women.
Blueberry juice and extract improve insulin sensitivity. Blueberry is a high fiber food that is an essential part of the diabetic diet and helps lower the blood sugar levels. Research by Dr. JoAnn Manson, a professor of Medicine, Harvard Medical School, proves that consumption of berries is associated with a lower risk of type 2 diabetes.
Protect Heart Health
Blueberries help in preventing atherosclerosis, heart attacks, and strokes. This is due to the presence of fiber, anthocyanin, potassium, folate, vitamin B6, and vitamin C in them. Fiber and anthocyanin reduce cholesterol, improve blood fat, and prevent clogging of arteries. Vitamin B6 and folate prevent blood vessel damage by inhibiting build up and potassium regulates the working of heart muscles.
According to a report published by, Dr. Lynn S Adams, Sheryl Phung et al., of Division of Tumor Cell Biology, Beckman Research Institute of the City of Hope, CA, in the Cancer Research Journal, blueberries have anti-cancer properties. The results of their studies suggest that the oral intake of blueberries could be a key component of long-term cancer prevention strategies. A team of American researchers published a report in the Nutrition and Cancer Journal stating that it contains certain compounds like pterostilbene (an excellent remedy for colon and liver cancer) and ellagic acid. These two in harmony with anthocyanin and other antioxidants like vitamin C and copper have the potential to prevent cancer.
Improve Brain Function
The vitamins, minerals, and phytonutrients in blueberries help heal nervous disorders amongst children in the age group of 7-10 years by preventing the degeneration and death of neurons, suggests a study published in European Journal of Nutrition by Whyte AR, et. al. These essential nutrients also protect brain cells and help restore the health of the central nervous system. The berries can lower your risk of suffering from disorders like Alzheimer’s disease to a great extent, according to a study published in the Journal of and Food Chemistry. They can even heal damaged brain cells and neuron tissues to keep your memory sharp.
The high fiber content present in them promotes digestion and weight loss. They also promote satiety, help you feel full, and reduce belly fat. One cup of blueberries contains only 15 g of carbohydrates and 84 calories. Thus, frozen or dried blueberries are great low-calorie snacks.
Rich in Antioxidants
The antioxidants along with other phytonutrients and flavonoids present in blueberries are responsible for the free radical scavenging activity in the body. The group of flavonoids, in particular, anthocyanin, prevents the body from all types of damage due to free radicals.
A number of studies published in the Journal of Agricultural and Food Chemistry establish that high amounts of antioxidants are beneficial to the body in a number of ways. This includes cellular structure damage, DNA damage, and early aging.
Other benefits of blackberries include:
Flavonoid-rich wild blueberries help enhance mood and act as an effective.
The roughage (fiber) present in blueberries prevent constipation. Also, the vitamins, sodium, copper, fructose, and acids improve digestion by stimulating secretion of correct gastric and digestive juices. This helps the food move smoothly through the system.
Treat Urinary Tract Infection
Blueberries can kill bacterial colonies like E. coli which are responsible for the urinary tract infection. They have a compound formed of large, polymer-like molecules, which inhibit the growth of such bacteria. They also have certain antibiotic properties which add to this effect. So far, this compound has only been found in cranberries and blueberries.
Blueberries can prevent or delay all age-related ocular problems due to their antioxidant properties. These include macular degeneration, cataracts, myopia and hypermetropia, dryness, as well as infections pertaining the retina. They contain special antioxidants called carotenoids (lutein, zeaxanthin etc.), flavonoids (like rutin, resveratrol, quercetin etc.), and other antioxidant compounds, which are all very beneficial for ocular health.
Antioxidants in blueberries can boost your immune system and prevent infections. Once your immune system is strong, you won’t catch colds, fever, pox, and countless other communicable diseases spread by bacteria and viruses.
Reduce Muscle Damage
Blueberries help reduce the muscle soreness and fatigue that occurs after a strenuous exercise or activity. They also help in muscle . This is confirmed by a study published in the Journal of the International Society of Sports Nutrition.
They help promote hair growth. Mix blueberries and olive oil, apply the blend to hair and roots and rinse with warm water to enhance hair growth.
Blueberry husks consumed along with probiotics show potent anti-inflammatory properties which can treat inflammatory bowel syndrome (IBS) and Crohn’s disease. They can alleviate symptoms such as bleeding and pain caused by ulcerative colitis.
Polyphenols and resveratrol found in blueberries help increase longevity and decrease the adverse effects linked with aging. They also activate the genes involved in anti-aging and decreasing brain function decline.
There are five major types of blueberry:
- Northern Highbush
- Southern Highbush
Blueberries could practically be an addition to any food to impart a sweet-tart taste. They could be used as toppings or be added to various dishes like over baked foods, oatmeal, yogurts, pancakes, smoothies or salads.
Select and Store
Here are a few tips to remember while buying and storing blueberries:
- They are available in fresh, frozen, and dried form.
- Frozen blueberries lose texture faster than fresh berries, but the flavor remains the same.
- Always select fresh firm blueberries as they are moisture free and last long
- Freeze and enjoy snacking them!
A few side effects include:
- Blood-thinning: People taking blood-thinning medication (warfarin) or suffering from blood disorders (hemophilia) should avoid blueberries. The vitamin K content may interfere with the blood thinning and result in blood-clot.
- Allergy: They may cause food allergy like itching, swelling or difficulty in breathing.
- Blood sugar control: They may lower blood glucose levels, especially for diabetics.
Note: Avoid use before or after surgery as blueberries can interfere with blood sugar control.
A final interesting thing to know about them is that the darker the color of the blueberries, the richer they are in antioxidants and other medicinal nutrients. In other words, eat them until your tongue turns blue in order to live a long and healthy life.
