FoodnMood: Turkey Saves the Brain

Antioxidants abound in holiday meals—and they're good for the brain to boot.

This may come as a surprise to you, but some of the foods most
likely to enliven the holiday table are really good for you and can
deliver a bundle of benefits to your heart and your brain. As a matter of
fact, what's good for your heart is also good
for your brain.

From stuffing to cranberries to red wine to hot chocolate, and even
that last sip of coffee, there are many traditional dishes that boost
blood flow to your most oxygen-hungry organs and preserve and even enhance
mood, memory and other mental functions. Call them brain savers.

Take stuffing. Turkey's traditional holiday
partner is rich in antioxidants. Bread crust is packed with them,
far more so than the less chewy inside of bread.

Antioxidants are premiere disease-fighters and anti-aging agents.
They are compounds that scavenge free radicals of oxygen, unstable
molecules given off by the body's many metabolic actions. Free
radicals are thought responsible for making cholesterol harmful to
arteries and the heart and for impairing memory and movement with age.
They are particularly drawn to the fat-rich membranes of nerve cells
through which all brain activity takes place. They are implicated in
immune dysfunction and in cataracts and macular degeneration of the

The body manufactures some antioxidants, although the brain needs
to import those it needs from food. Under conditions of stress, the
body's ability to produce antioxidants is impaired. Fruits and
vegetables are the richest source of antioxidants.

Cranberries virtually top the list of antioxidant-rich foods.
Scientists have developed a way of measuring the antioxidant content
of foods, called ORAC, for oxygen radical absorbance capacity.
Cranberries outpulled some highly touted antioxidant rich
goodies—strawberries, spinach, raspberries, broccoli, beets, red
grapes and cherries, among 11 others.

High-ORAC food may help slow the aging process in both body and
brain. Most Americans average about 1,670 ORAC units daily. Increasing
fruit and vegetable intake can double antioxidant activity. One cup of
blueberries—first cousin to the cranberry—alone supplies
3,200 ORAC units

Studies in animals suggest that cranberries are particularly
neuroprotective, good at battling chronic age-related
afflictions like loss of coordination and memory. They protect brain cell
from the free-radical damage that normally occurs over time, thereby
preserving cognitive and motor functions. Compared with animals fed a
standard diet, aging animals given cranberries showed actual improvements
in normal age-related declines in working memory, reference memory,
balance and coordination. Indeed, they were able to keep on learning.

The antioxidants in cranberries belong to a group of chemicals
called phenols. The strongest of these, and most extensively studied, are
procyanidins and anthocyanidins, which give cranberries and blueberries
their deep color. They seem to be particularly adept at turning off a
brain enzyme (xanthine oxidase) that actually stimulates the creation of
free radicals of oxygen.

But there are many other antioxidants in cranberries, and they are
just now coming under scrutiny for their function. Researchers
increasingly believe the combination of nutrients found in food are more
protective than individual nutrients taken alone.

One antioxidant compound in cranberries actually helps ward off
urinary tract infections. It blocks some harmful bacteria from
attaching to the cells lining the urinary tract.

Cranberries are so powerful in preserving brain function,
researchers found, that by their antioxidant action they can
reduce the severity of brain impairment following a stroke. They protect
against the brain cell damage that usually occurs in the early stages
after a stroke. Exposure to a concentration of cranberry extract
equivalent to about half a cup of whole cranberries resulted in a 50 percent
reduction in brain cell death.

And go ahead, finish it all off with a cup or two of coffee.
Researchers have identified an antioxidant in coffee that is
particularly potent in preventing colon cancer.

Or savor a cup of hot cocoa. Pure cocoa powder tops both red wine and tea in antioxidant power—two times more than red wine, two to three times more than
green tea, and up to five times more than black tea. Apparently, heating the cocoa brings out the antioxidants in it.
