University of Washington scientists say that fruits and veggies may be the answer to avoiding dementia.

The scientists examined 2,000 adults that did not have Alzheimer's disease and vascular dementia over a 10-year span, paying attention to their diet and cognitive functions.

They observed that those who drank fruit or vegetable juices three times or more a week were 76 percent less likely to develop Alzheimer's disease than those who drank the juices less than once a week. The effect was the most significant in those with the ApoE4 allele, a genetic marker that is a risk factor for Alzheimer's disease.

Researchers say that the polyphenols, an antioxidant found in fruits and vegetables, could be key to preventing the disease.

Next, the researchers want to check polyphenol levels to see if they are linked to a reduction in Alzheimer's disease, which could help pinpoint the type of juice that is the most beneficial to fight off the disease.

Break out the juicer... the study could give people more insight into which fruits and veggies should be a part of their diets.
