Could berries be medically-proven brain boosters? According to several recent studies, blueberries and strawberries – two berries high in flavonoids called anthocyanidins – appear to reduce cognitive decline in older adults. Anthocyanidins are plant compounds with powerful antioxidant and anti-inflammatory properties. A long-term study of over 16,000 participants over 70 years old suggests that cognitive aging could be delayed by up to 2.5 years in elderly who regularly consume the flavonoid-rich berries.
In a shorter study, researchers at the University of Cincinnati Academic Health Center found the memory function of older adults with early memory decline was boosted by drinking the juice of wild blueberries for 12 weeks.
A much larger long-term study of over 134,000 women and 47,000 men found that those eating at least one serving a week reduce their risk of developing high blood pressure by 10%. Participants consuming the highest amounts of anthocyanins (found mainly in blueberries and strawberries in the US) were 8% less likely to be diagnosed with high blood pressure than those consuming the lowest amounts. The effect was even stronger in participants under 60, and the effect was strongest for those who consumed blueberries as opposed to strawberries.
Curious about how anthocyanins work? See this in-depth article on antioxidant health benefits. Blueberries are one of the richest sources of anthocyanins, although other contributing sources include blood oranges and orange juice, raspberries, tea, red wine and apples. Packed with vitamin C, vitamin K and fiber, blueberries get their color from the rich density of anthocyanins.
