Too many vitamins can endanger health, says USDA nutritionist
Too much of many vitamins and
minerals can prove as harmful to
human health as too little, a U S
Iteparlment of Agriculture nutri
tiomst said today
"Your body needs only so much of
each nutnent sometimes only s
trace vaid Helene S Guttman. a
nutritionist with USDA'a Agricult ur
al Hevearch Service
Guttman 11
associate director of CSIM's Human
Nutrition Kesearch Center at Hells
Mile Md
Overdoses of certain vitamins,
like A and I), can make you seriously
ill. and large doses of Vitamin E
over long periods can produce flu
like symptoms
Many other vita
mins and minerals have to be
ingested in proper balance with one
another
Too many Americans believe
that if one of something is good, then
two or three must he better That is
definitely not the case with vitamins
and minerals
she said ‘ Huying
too many vitamin supplements can
also tie hard on the pocket book
The initials "R D A ” on food boxes
and vitamin bottles stand for "K e
commended hietary Allowance
"They mean what they say,"
Guttman said "Once you have 100
percent of what you need and you
self prescribe with many times
more of a nutrient, you force your
metabolism to work overtime to
rebalance
Some people are sue
cessful in this rebalancing act.
others are not "
Guttman said an elderly neighbor
was suffering from memory lapses
while taking large supplements of
several so-called anti stress" vit
amins
"She feared tiecoming senile," she
said, "hut when she cut back on the
vitamins to no more than the RDA
for each, her memory improves! in a
few days She is an example of a
person whose metabolism could not
rebalance when confronted with
excessive trace nutrients
According to James (' Smith. Jr ,
who works with Guttman. vitamins
and minerals that must be ingested
in proper balance are iron, zinc and
copper Smith is chief of I'SDA's
Vitamin and Minerals Nutrition
Laboratory
Recent research. ' Smith said,
"leaves no doubt that pregnant
women and lactating mothers re
quire supplements of iron and zinc
But we find too much iron inhibits
the body s absorption of zinc, and too
much zinc, in turn can antagonize
the body 's copper "
IVtassium and sodium also have
to be kept in balance. Smith said
Many adult Americans are apt to get
more sodium than they need and less
potassium
"U S D A researchers recently-
found during a one year study that
blood pressure in men was lowest
when their potassium intake was
highest," he said
Guttman said self administered
overdosing with folic acid, another
supplement available at the vitamin
counter, can also cause problems
"It you take huge doses of folic
acid to cure a vitamin B12 associ
ated anemia you can cause real
trouble for yourself, said Guttman
There are several types of vita
min-deficiency anemias." she said
"Some are caused by an insufficient
amount of vitamin HI2 and others by
insufficient folic acid The folic acid
mobilizes the vitamin B12 present in
the liver and gives a temporary
remission of symptoms, so that you
don t notice your mistake right
away
‘ But then the liver runs out of
vitamin B lI to contribute, and there
is a terrible relapse Even worse,
vitamin H12 is scavenged from the
nerv ous system and you can end up
with something worse vitamin B12
deficiency problem of the nervous
system called combined system dis
ease "
She said the surest way to a
nutritionally adequate diet for most
adults is to rat balanced diets
containing a variety of food
"It's good to he an adventurous
diner, she said
"That way you
won't get bored and meals become
and remain a pleasant experience
"The Chinese philosopher who
advised all things, but in modera
lion was on the right track when it
comes to good nutrition When you
get your nutrients from a wide
variety ol foods instead of pills, you
not only gel the vitamins and miner
als we know about you also get all
those good things that haven't twen
discovered yet

nutrition is far from complete
He said recent studies show chro

hoth hyperglycemia and hypogly
cemis too much sugar in the blood
and too little
l SDA scientists at
Heltsville Md
have
found that
most people have a marginal intake
of chromium
Bather than taking pills what can
you eal that is high in chromium’
t'ereal products, nuts and mush
rooms said Smith
Black pepper
and brewer's yeast are
relative
l> high in chromium, but the usual
diet contains little of these
There
mav be special cases where meas
urist supplements of specific miner
als such as chromium are neces
sary ”
Smith said USDA scientists re
centlv found the increased popular
itv of running and other forms of
strenuous exercise may increase
dietary needs for chromium and
zinc
There is an increased excretion
of those two minerals among people
who exercise regularly ami hard,
he said
Guttman Smith and their l SDA
colleagues study ways to define
human requirements for essential
nutrients and the metabolic role of
nutrients alone and in combination
with other substances

The young President often
