Blueberries have more to offer than just good looks and good taste. Besides
being a good source of Vitamin C and fiber, they have an exciting nutrition
story to tell too! Let's check out the facts and look at the nutrition label
for blueberries. One cup of blueberries equals one serving. And this amount
of blueberries has 15% of the Vitamin C and 14% of the dietary fiber our bodies
need every day. That's why blueberries are good sources of these nutrients.
Just like all other fruits, blueberries contain no cholesterol or fat and
are also low in calories. Blueberries are a great choice when choosing berries
this summer!
New studies by USDA scientists and the University of Illinois point to health
benefits from eating blueberries that may be as far reaching as preventing
cancer and retarding the effects of aging - particularly the loss of memory
and motor skills.
The focus has been on flavonoids, including anthocyanins, which are responsible
for the intense blue color of wild blueberries. USDA scientists Dr. Ronald
Prior and Dr. Guohua Cao from the Jean Mayer Human Nutrition Research Centre
on Aging at Tufts, recently tested some 40 fruits and vegetables and found
that blueberries are number one in antioxidant activity.
Antioxidants prevent
cancer-causing cell damage and may thwart the effects of some age related
diseases. Animals fed a diet of blueberry extract showed fewer changes in
brain function due to aging, which could mean improved cognitive and motor
skills. USDA researcher Dr. James Joseph attributes the beneficial effect
of blueberries to their high anthocyanin content. Another study conducted
by Dr. Mary Ann Smith of the University of Illinois looked at a flavonoid
that inhibits an enzyme involved in promoting cancer. Of the fruits tested,
blueberries showed the greatest anti-cancer activity.

Dr. Richard Passwater, Ph.D., research director at Maryland's Solgar Nutritional
Research Center -
Before singing the blues about bruises, wrinkles or varicose veins, start
eating the blues--fruits with large amounts of blue, deep red or purple pigment.
Proanthocyanoidins (PACs) produce these rich colors and help our skin. PACs
are water-soluble which means they can travel where fat-soluble vitamins can't,
says Dr. Passwater, thus strengthening tiny blood vessels called capillaries.
And strong capillaries mean: Less constriction of veins,which could lead to
swollen feet or ankles. Faster healing of bruises. Healthy collagen for fewer
wrinkles. Fewer swollen, or varicose, veins. You can judge a fruit's PAC content
by its color, says Dr. Passwater. Look for dark-blue, purple or dark-red shades--the
darker the better. Some of the best sources are blueberries, huckleberries,
plums and red or purple grapes. Another option is dark wine, made from the
stems and skins as well as the fruits.
