VITAMINS
NECESSARY FOR HEALTH, NUTRITION RESEARCHER SAYS
MANHATTAN
-- Making sure your diet contains plenty of beta-carotene and anti-oxidants
is an important aspect of maintaining good health says a Kansas State
University nutrition professor.
Rick
Baybutt, who holds a doctorate in nutrition from Penn State, said anti-oxidants
-- beta carotene, vitamin E and vitamin C -- are prevalent in fruits
and vegetables.
The nutrition
researcher is currently investigating the impact of nutrients and their
effect on lung disease.
Baybutt
encourages smokers, who are at a higher risk for lung cancer and emphysema,
to stop smoking. But, if smokers do not quit, he suggests they increase
their intake of beta-carotene and anti-oxidants.
Baybutt
said the RDA, recommended dietary allowance, of vitamins was established
with healthy people in mind. The amount needed by those who smoke, or
who have degenerative diseases, may be higher.
"Beta-carotene
comes from yellow and green vegetables and protects against cancer of
the lung, stomach, pancreas, liver, colon, breast and prostate. It stimulates
the immune system and is vital for lung cell repair," Baybutt said.
"Minerals
like zinc, copper, manganese, selenium and iron are important because
of the anti-oxidant enzymes they activate," he said. "Although obtaining
these nutrients from eating food sources is better, taking a multiple
vitamin every day is fine, too."
Baybutt
takes a multivitamin every other day himself. He buys generic vitamins.
"There's
no advantage to buying expensive vitamins," Baybutt said. "Also, consumers
shouldn't be taken in by claims about 'natural' vitamins. 'Natural'
vitamins are the ones you get from eating spinach and carrots. Once
the vitamins are in pill form, none are more natural than any others."
Consumers
often are misled by labels on vitamin bottles, Baybutt believes. For
example, on a bottle of beta-carotene, the label indicates that each
pill contains between 10,000 and 25,000 I.U. -- international units
of beta-carotene. This is equivalent to 6-15 mg of beta-carotene, which
is the amount that is found in one medium size carrot.
"Know
what you are buying and be a knowledgeable consumer," he said.
"It's
best to get nutrients from foods," Baybutt said. "And green leafy vegetables
like spinach and kale have the highest concentration of orange carotenoids.
These naturally occurring anti-oxidants help prevent oxidative damage
and protect the body from disease."
