Alzheimer's and Free Radicals

It has long been hypothesized that nerve-cell death like that found in Alzheimer’s patients is caused by highly reactive molecules called free radicals. Brain damage from free radicals can build up over time, leading to severe mental impairment. This free-radical damage has been observed in the Alzheimer’s-afflicted brain and may be the key to the development of beta-amyloid plaques and neurofibrillary tangles (the two main neuropathological characteristics of Alzheimer’s disease).

Fortunately, a diet rich in whole grains, fruits, and vegetables can provide an abundance of antioxidants that can help prevent Alzheimer’s disease. Antioxidants, including vitamin C, vitamin E, beta-carotene, and selenium, can counteract the damaging effects of free radicals in the brain and throughout the body. These powerful, natural chemicals are naturally found in vegetables, fruits, grains, and beans. Plants are loaded with antioxidants that have been shown to counter the brain-damaging effects of free radicals.

A large study reported at the World Alzheimer’s Congress found that “[o]n average, people who remained free from any form of dementia had consumed higher amounts of beta-carotene, vitamin C, vitamin E and vegetables than the people in the study who developed Alzheimer’s disease.” The best way to defend against aging and keep your mind in working order is to dump meat and dairy products and load up on healthy vegetarian options.
