Blueberries Health Benefits
Blueberries offer a host of health benefits. Often referred to as a “superfood,” They contain powerful antioxidants and have been linked to heart and brain health.
1. Full of Antioxidants
Blueberries are a renowned powerhouse of antioxidants. Antioxidants fight against free radicals and other reactive species in the body that are thought to contribute to the development of certain kinds of cancer and heart disease, as well as aging (2).
Blueberries some of the highest antioxidant activity of commonly consumed fruits (3). They’ve been found to be high in flavonoids, a type of antioxidant (4).
Polyphenols are a type of flavonoid.
Antioxidants also tamp down inflammation in the body. Diets high in antioxidants have been linked to helping a variety of inflammatory conditions. They also improve overall health.
Bottom Line: Numerous studies have linked antioxidants to the prevention or improvement of a variety of inflammatory conditions like heart disease, certain cancers, and more.
2. Blue Brain Booster
Due to their antioxidant content, blueberries may help with certain conditions affecting memory and cognition.
Berries have been found to help with memory and learning in animal studies.
This is due possibly to polyphenols interacting with aging neurons, and reducing stress on cellular signals in the brain (5).
One study found that drinking blueberry juice daily improved memory function. It is thought the anthocyanins, a polyphenol, and antioxidant that gives blueberries their blue hue, is responsible (6).
Another study found that adults that ate blueberries and strawberries had slower rates of cognitive decline and aging by up to 2.5 years (7).
More studies are needed to isolate exactly how these powerful compounds are improving memory and cognition, but it appears that regularly including blueberries in your diet may give your brain a boost.
Bottom Line: The antioxidants in blueberries have been linked to improving memory function and cognition.
3. Keeps Heart Healthy
Blueberries may also be good for your ticker. Several studies have shown the positive impact these little berries may have on blood pressure and heart health.
Antioxidants, like those found in blueberries, have been found to be helpful in protecting blood vessels.
Resveratrol, flavonoids, and anthocyanins have been found to improve heart health, and all of these polyphenols are found in blueberries (8).
Numerous studies have demonstrated the importance of polyphenols in promoting cardiovascular health and have underscored the positive role these compounds play in limiting the effects of aging.
Antioxidants have been gaining recognition as a way of reducing oxidative stress in blood vessels, thereby improving overall blood vessel health and function (8).
In addition to its noteworthy and acclaimed presence in red wine, resveratrol is found in red grapes, blueberries, peanuts, hops, pistachios, as well as cranberry and grape juices.
