In a recent study, researchers discovered that the extracts of certain berries helped combat oxidative stress and DNA damage, both of which play roles in the development of Alzheimer's disease. The researchers studied extracts from blackcurrants and boysenberries, two kinds of berries high in potent disease-fighting anthocyanins.

Blackcurrants are small, juicy, dark purple berries that are high in vitamin C and have a slightly bitter taste. Boysenberries are genetically similar to blackcurrants. Both berry types are rich in anthocyanins, potent disease-fighting antioxidants. Fruits high in anthocyanins tend to have deep red or purple hues. In a recent study, researchers discovered that both blackcurrant and boysenberry extracts helped combat oxidative stress and DNA damage, two processes that contribute to Alzheimer's disease, cancer, and aging. Although the study results are preliminary and need to be confirmed with further research, antioxidant-rich fruits remain a smart food choice. Eat a colorful assortment of different fruits and vegetables to get a healthy mix of disease-fighting compounds every day.
