Ask Horton: an elephant never forgets. Humans, on the other hand, do so all the time and with increasing frequency as we get older. Once you hit my age, it’s: “what was your name again?”

We have long known that blueberry helps with mental clarity and focusing your thoughts. Now, there is another source of evidence that indicates how blueberry can help prevent memory loss in the elderly. The anthocyanins of blueberry (the polyphenolic antioxidants) had earlier been shown to be associated with neuronal signal activity in the brain.

Sure enough, those elderly patience, who had exhibited early signs of memory “changes” improved after taking blueberry juice treatment for 12 weeks.
