You probably already know that blueberries are delicious. And you may have heard that they’re healthful, too.But did you know that blueberries boost memory in older people at risk for memory loss? A study looked at how drinking wild blueberry juice affected¹ nine adults in their 70s with signs of memory loss. They drank two-and-a-half cups of juice every day for twelve weeks. A control group of seven other older adults drank a placebo² not containing blueberries. The juice drinkers performed significantly better on memory tests, including word association and list learning.So What Makes Blueberry Juice Such A Potent³ Memory Food?
