STUDY: VITAMIN C MAY NOT HELP CANCER PATIENTS -- RESEARCHERS WARN MEGADOSES
COULD PROTECT TUMORS FROM TREATMENT
TAMPA, Fla. -Cancer patients who take large doses of vitamin
C in the hope of a cure might actually make their disease worse by inadvertently
protecting their tumors from radiation and chemotherapy, new research suggests.Doctors
caution they cannot prove the vitamin is harmful during cancer treatment.
But they say there are strong biological reasons to think megadoses could
be bad. The concern is based on the discovery that cancer cells contain
large amounts of vitamin C, which appears to...

says Dr. Richard Shekelle and colleagues at the University of Texas School
of Public Health in Houston.The Texas researchers have been tracking a
large group of men for about 25 years. In the latest analysis, they compared
the diets and death rates of middle-aged men. They found that men eating
the most vitamin C and beta carotene were only half as likely...

HEALTH A NEW STUDY FINDS THAT A LITTLE MORE IS A LOT BETTER

question, researchers at the UCLA School of Public Health recently analyzed
findings from a decadelong federal health survey. The results, published
last week in the journal Epidemiology, at least bolster...

VITAMIN C LINKED TO DNA DAMAGE, LAB STUDY SAYS VITAMIN AIDS IN
PRODUCTION OF TOXINS
The vitamin C pills taken by millions of health-conscious Americans
may actually help produce toxins that can damage their DNA, a step toward
forming cancer cells, a laboratory study suggests.In a study appearing
today in the journal Science, University of Pennsylvania researchers said
they found in test tube experiments analyzing the action of vitamin C that
the nutrient can act as a catalyst to help make a toxin that can injure
DNA, the body's genetic code. The findings do...

ASCORBIC ACID OFFERS SAME VITAMIN C AS ROSEHIPS
Q: I have heard that the ascorbic acid used in many vitamin
C supplements is not the best form of vitamin C for the body. I read that
rosehips should be used for vitamin C. Is this correct? I have tried without
much luck to find a chewable vitamin C with rosehips as the C source. Does
it really matter?A: Rosehips are one of the richest natural sources of
vitamin C. However, because they are relatively costly, it is doubtful
that you will find a vitamin C supplement that relies exclusively...

Vitamin C: A history of healing properties
What may be the best known of all the vitamins, vitamin C has
been acknowledged by doctors for its effectiveness in preventive medicine.
Almost half of adult Americans take it in some form on a daily basis.Prehistoric
hunter-gatherers, who consumed a diet rich in fruits and vegetables, may
have included a whopping six to eight times the amount of vitamin C on
a daily basis than the amount found in the average American diet today.
In modern times, vitamin C (also called ascorbic acid) was...

Vitamin C adds years to men's lives, study says
LOS ANGELES - Men who consume a few hundred milligrams of vitamin
C every day live about six years longer than men who don't, and the vitamin
may extend women's lives by about a year, a study suggests. The U.S. government's
recommended daily allowance of vitamin C is 60 milligrams for most adults.
But the study indicates that consuming 300 to 400 milligrams daily might
help people live longer, said its author, James E. Enstrom, an epidemiologist
