Quercetin, a potent antioxidant found in apples, protects against Alzheimer's disease

by Mike Adams, the Health Ranger, NaturalNews Editor

In a recent study, isolated rat brain cells were exposed to concentrations of either quercetin or vitamin C. The cells were then exposed to hydrogen peroxide to simulate Alzheimer’s damage. The results were compared to brain cells similarly exposed, but not pretreated with antioxidants. Brain cells that were treated with quercetin had significantly less damage.

Per serving, fresh apples have higher levels of the antioxidant quercetin compared to other fruits and vegetables. Because quercetin is concentrated in the skin of apples, eating them fresh provides a better source.

Alzheimer’s causes severe memory loss, and eventually death. It affects an estimated 4.5 million people in the U.S., mainly the elderly.
