Blueberries
Blueberries: more than just good taste
It has long been known that antioxidants work to counteract the
effects of aging and disease by fighting against free radicals.
Free radicals are highly reactive molecules that contribute to
various health problems ranging from cancer to the flu. Fresh
vegetables and fruits are good sources of the antioxidants that
neutralize free radicals, and it is now known that blueberries
are the best source of all.
A study done at Tufts University in 1997 showed that, ounce for
ounce, blueberries contain 3 times more antioxidants than spinach
or an orange. The difference apparently comes from the color:
blue pigments called anthocyanins are potent antioxidants. They
are also found in strawberries and other blue and red fruits.
Preliminary studies involving blueberries have also been done by
the U.S. Department of Agriculture. Rats given a diet supplemented
with a few blueberries every day showed fewer signs of the mental
and physical slowing that can come from aging. Diets that included
strawberries and spinach were also effective.
