The anthocyanins of which blueberries and other dark berries are rich in have been shown to reduce the amount of DNA damage, has been shown to reduce significantly, although, albeit, slightly, excuse me, cognitive decline. And that particular study was supplementation of a blueberry extract. I'll talk about the difference between extract and actual blueberries in a moment. But supplementation of blueberry extract in offsetting cognitive decline in elderly people. So what constitutes elderly is always a little bit of a debate and a discussion. But in this case, what they did, is they supplemented with somewhere between 428, I don't know why they selected 428, and 598 milligrams of anthocyanins daily for 12 weeks was associated with improvements on verbal learning and memory.
