RDA Update Leaves Critics Hungry
SUMMARY: After nine years of delays, the new list of recommended
dietary allowances has drawn criticism from many experts. Chief among the
complaints are levels of vitamin C and calcium they say are too low to
be healthful. Advocates say the levels should be viewed not as a guide
for consumers but as a means to evaluate nutrition needs. TEXT: How much

Such questions simmer almost constantly among nutritionists,...

LAB STUDY: VITAMIN C PILLS MAY BE HARMFUL, VITAMIN HELPS PRODUCE
TOXINS THAT CAN DAMAGE DNA
WASHINGTON --- 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...

LIMITS SET ON INTAKE OF VITAMINS C, E U.S. WARNS OF POSSIBLE SIDE EFFECTS
You can get too much of some good things, including vitamins

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 agency also called...

VITAMIN C DEFICIENCY LINKED TO HEART ATTACKS
Vitamin C may be important in protecting against heart attacks,
Finnish researchers reported Friday. Men deficient in the vitamin were
more than three times as likely to have a heart attack, they said.Jukka
Salonen and colleagues at the University of Kuopio studied 1,600 men ages
42 to 60 from eastern Finland, where people tend not to absorb much vitamin
C and where deaths from heart disease are common. All the men were free
of heart disease at the start of the study. From 1984 to 1992, 70...

STUDY FINDS LOW DOSES OF VITAMIN C CAN BE HIGHLY POTENT IN ELDERLY PATIENTS
It's astonishing how even modest doses of vitamin C can help
elderly people recover from severe respiratory infections. That's what
doctors at St. Luke's Hospital in Huddersfield, United Kingdom, recently
discovered.In a study of 57 elderly patients hospitalized for acute bronchitis
or pneumonia, about half received 200 milligrams of vitamin C per day;
the others got a placebo. Within two weeks it was apparent that those on
vitamin C were doing...

HIS BELIEF IN VITAMIN C UNSHAKEN BY THE BIG C
PALO ALTO, Calif. For a quarter century, two-time Nobel laureate
Linus Pauling has taken megadoses of vitamin C and a lot of flak from skeptics
for trying to stave off the deadly C cancer.Time and disease finally caught
up with him in his 10th decade, he said Wednesday, revealing he was diagnosed
with prostate cancer five months ago. But at 91, he says he's recovering.

DAILY DOSE OF VITAMIN C CAN ADD YEARS TO LIFE
Vitamin C may help people live longer - men by up to six years
and women for about one year.That's according to a new study that also
emphasizes that it's better to get your vitamin C dose from five daily
servings of fresh fruits and vegetables instead of vitamin pills. Researchers
found that taking 300 to 400 milligrams of vitamin C daily may help men
live about six years longer than men who don't. For women, the benefits
are about one year.The...

STUDY BOASTS OF VITAMIN C BENEFIT
Planning to father a child? Be sure to eat enough vitamin C.
It could mean the difference between a healthy child and one with birth
defects. That is the astonishing conclusion of a new study by Bruce N.
Ames, Ph.D., and colleagues at the University of California at Berkeley.
The team found that even a slight lack of vitamin C can lead to damaged
sperm, boosting the chances of birth defects in offspring.In one test,
a group of men with low semen levels of vitamin C showed the most damage...
