Vitamin C may damage DNA
Vitamin C pills, popped by millions as a protection against
colds and other diseases, actually may play a role in damaging DNA, a step
toward forming cancer cells, a laboratory study suggests.In a test tube
experiment analyzing the action of vitamin C, University of Pennsylvania
researchers found that the nutrient can act as a catalyst to help make
a toxin that wounds DNA, the body's genetic code. The study appears Friday
in the journal Science.The findings do not mean...

Warning: You can get too much of vitamins C and E
WASHINGTON - You can get too much of some good things, including
vitamins C and E, the federal government's watchdog for nutritional standards
said last week. For the first time, the Institute of Medicine, part of
the National Academy of Sciences, set limits on daily consumption of vitamins
C and E in an effort to reduce the risk of adverse side effects from overuse.While
institute scientists found that extremely large doses of the substances
could cause health problems, the IOM...

Vitamin C may fight hypertension
Heart patients with high blood pressure may receive substantial
benefit from a daily dose of vitamin C - something researchers said could
be an inexpensive alternative to prescription drugs. A dose of 500 milligrams
each day lowered blood pressure by up to 9 percent, a level comparable
to expensive prescription drugs, according to researchers from the Boston
University School of Medicine and the Linus Pauling Institute at Oregon
State University. "It may provide a way to bring their...

Vitamin C breakthrough may prevent wrinkles
It's a nutrient credited with everything from curing the common
cold to preventing heart disease and even cancer, and now it also may be
the ticket to looking eternally young. It's Vitamin C, which some say is
the hottest topical anti-aging ingredient ever. ``The science is really
there. This is not just another cosmetic company hype,'' says New York
City dermatologist Dr. Deborah Jaliman.When used in the proper form (L-ascorbic
acid) and in...

HIGH VITAMIN C LEVELS BOOST PRODUCTION OF GOOD CHOLESTEROL
If you have lots of vitamin C in your blood, your chances of
heart disease sink. That's because high vitamin C equals high HDL cholesterol,
the good type that seems to combat heart disease.Such is the conclusion
of a new study by Judith Hallfrisch, Ph.D., at the U.S. Department of Agriculture's
Human Nutrition Research Center in Beltsville, Md. Hallfrisch measured
the amount of vitamin C in 827 adults. Regardless of their age, sex, weight
or smoking habits, those...

VITAMIN E NEUTRALIZES HARMFUL CHOLESTEROL
High doses of vitamin E lower the risks of heart disease by
helping neutralize the "bad" kind of cholesterol, but vitamin C has no
such effect, researchers reported Saturday.University of Minnesota scientists
said a study of patients taking supplements of vitamin E and vitamin C
showed that only E was able to keep low-density lipoproteins (LDL), the
"bad" cholesterol, from turning into a killer chemical that attacks arteries.

GOVERNMENT SHOULD DO MORE RESEARCH ON VITAMIN C
Horses do it. So do pigs, cows, goats, rats, chickens, your
pet dog, and even frogs and snakes.Humans are oddballs among most other
animals on earth. We rank with monkeys, Indian fruit-eating bats, and a
few other creatures that have lost the ability to synthesize their own
supply of vitamin C. The overwhelming majority of other animals make vitamin
C -- ascorbic acid -- in their liver or kidney cells.Hundreds of millions
of years ago, man's ancestors simplified themselves...

STUDY: LOW VITAMIN C CAN DAMAGE SPERM
WASHINGTON -- Men with low levels of vitamin C are more likely
to have genetically damaged sperm, researchers say in a study to be published
today.Bruce Ames, leader of a vitamin C study at the University of California
at Berkeley said that an analysis of sperm from 24 men showed that of 15
with below normal levels of vitamin C, eight had high levels of genetically
damaged sperm. "We know that you get into trouble if your level of vitamin

VITAMIN C CAN BE OF HELP TO HUNTERS WHO HAVE PUSHED THEIR BODIES TOO
FAR
Linus Pauling probably is too old to chukar hunt, but praise
for Oregon State University's stellar alumni-emeritus and Nobel prize-winner
are being sung into the winds of desert canyons.Vitamin C, it seems, is
more important to some chukar hunters than to those who use it to ward
off colds. An article in Outdoor Life reports ``Every hunter has pushed
himself to the point where his muscles are screaming, `no more!' But there
is a solution to the aches, pains, and...
