Scientists and dieticians have long advocated the consumption of an apple a day - you know, to keep the doctor away.

     Now, there appears to be solid evidence that a glass of wine per day may help combat Alzheimer's Disease.

     According to the Journal of Alzheimer's Disease, the benefit seems to come not from a large single dose - a practice doctors often embrace when trying to fight a specific disease or condition - but rather from "reasonable and chronic consumption."

     According to Mario Ferruzzi of Purdue University, "It's like eating an apple a day, not a case of apples over two days every month."

     In this case, "reasonable and chronic" would equate with about one glass - approximately 4 to 6 ounces - of red wine per day.

     According to studies, polyphenols - which are compounds found in the skins and seeds of grapes - are believed to prevent the formation of beta-amyloid protein. It's that protein which creates plaque in the brain, ultimately causing the onset of Alzheimer's.

     Researchers at Mount Sinai School of Medicine in New York reached conclusions virtually identical to those reached at Purdue.
