Scientists believe that certain berries make blood vessels much more elastic and contribute to a good normalization of blood pressure. People who consumed flavonoid-rich berries were diagnosed with low blood pressure.
Strawberries and blueberries are rich in beneficial plant compounds called anthocyanins, which give the berries bright red, blue, and purple hues. Scientists have linked these compounds to improved human health.
Studies have found that women who ate more than three servings of blueberries or strawberries per week had a lower risk of a heart attack. The risk of heart attack decreased by 34% compared to those who ate fewer berries.
In addition, scientists believe that anthocyanins make blood vessels more elastic and help to normalize blood pressure, which is one of the risk factors for heart attack. Researchers have suggested that the gut may be partially responsible for the beneficial effects of flavonoids on blood pressure.
