A new study conducted among 69,622 women for 14 years documented food intake in four year intervals. Their diets were analyzed and examined for flavonoid consumption. Results show that women who consumed more citrus fruit containing flavonones, a subclass of flavonoids, had a 19% lower risk of having an ischemic stroke when compared to women who ate the least citrus fruit. Flavonones can be found in citrus fruits such as oranges, grapefruits, tangerines, clementines, lemons and limes. While citrus fruit juice can prove to be beneficial, it is best to eat whole fruits and whole fruit smoothies. Citrus fruit consumption is also linked with reducing the risk of heart disease and some cancers.
