Polyphenols in the brain
>



New research by Purdue researchers published in the Journal of Alzheimer's Disease suggests that polyphenols may be able to cross the blood-brain barrier after 10 or more days of regular, moderate consumption - in that antioxidant compounds were found in the brains of an animal subject group after consistent utilization. On the other hand, irregular, heavy consumption of polyphenols does not seem to provide a corresponding level of benefits. This category of antioxidant is found in red wines/grapes, berries, teas, and certain other natural substances and may inhibit the formation of amyloid plaques. Mastering the quantity, pacing, and variety of antioxidants in the diet appears to be key to optimizing the impact on human health.
