6. Heart Health
Blueberries are not just good for your eyes. They may also play a role in heart health, given that they are suspected to improve blood pressure. This is in part due to their modest potassium content, which contributes to more elastic blood vessels. In general, blueberries are thought to reduce blood pressure by restoring elasticity to blood vessels, so the heart has an easier time moving the blood through the circulatory system. Based on one study of pregnant women with higher blood pressure, there is a theory that additional nitric oxide production plays a role in the reduction of blood pressure.
5. Reduced Dementia/Alzheimer’s Risk
As mentioned earlier, blueberries can contribute to mental health. This is good news for those at risk of developing Alzheimer’s disease or dementia, given that these conditions have no cure. However, there are ways to delay and mitigate such illnesses, and it’s thought that blueberries do this by limiting the damage to brain cells due to a flavonoid called anthocyanin. This flavonoid has antioxidant properties, which means it protects the cells from damage. Specifically, the anthocyanin content of blueberries helps to preserve brain cells, which ultimately results in the brain staying stronger for longer.Related: 11 Predictors of Alzheimer’s
4. Better Digestion
Because of the antioxidant properties of blueberries, cells in other areas of the body can perhaps receive a little more protection from carcinogenic sources. This means that blueberries can help combat inflammation and cancer in the digestive tract, which breaks down the food we eat, as well as related organs. Additionally, blueberries, like several other fruits, provide a little bit of fiber to the body, which can help improve the digestive process by bulking up stool. Consider whipping up a blueberry banana smoothie to get a healthy dose of antioxidants and potassium.Related: 10 Foods That Help You Poop
