U.S. researchers
said a compound abundant in apples and other fruits and vegetables can
protect brain cells against damage linked to Alzheimer's disease.
Studies of rat
brain cells conducted by Cornell University researchers suggests a compound
called quercetin -- a powerful antioxidant -- can protect the cells from
oxidative stress, a tissue-damaging process associated with Alzheimer's
and similar disorders.
The research
adds strength to the theory that the risk of developing Alzheimer's could
be reduced by adjusting one's diet -- particularly by eating more antioxidant-rich
foods.
"On the basis
of serving size, fresh apples have some of the highest levels of quercetin
when compared to other fruits and vegetables and may be among the best
food choices for fighting Alzheimer's," said study leader C.Y. Lee.
"People should
eat more apples, especially fresh ones," Lee said, but cautioned that eating
any food to protect against Alzheimer's remains an unproven strategy.
Genetics and
environment also are thought to play a role in the disease.
Other foods
rich in antioxidants include blueberries, red wine, red grapes and dark
chocolate.
Alzheimer's
affects an estimated 4.5 million people in the United States, according
to the National Institute on Aging.
