Popping antioxidants?
We are all getting older. Not wiser nor necessarily
richer, just older. However, getting on in years still beats the
alternative. Just keep your place reserved in God’s waiting room but don’t
sit on it just yet and you’ll be right.
Now with living longer, there comes a price. Our organs can start to get
tired, so heart, liver, kidney can start to show a decrease in efficiency.
There is also the fact that cancer is, by and large, a disease of aging, so
anything that can reverse the aging process is of interest.
OK, so we are all living longer, what can we do to get our arthritic hands
on the elixir of youth? If you believe the popular press, the answer to
aging is multivitamins. Peddling mega-vitamins is a megabuck industry,
credited with improving your health, your love life and fixing everything
from falling hair to falling arches.
The latest trend is to take daily doses of antioxidants such as beta
carotene, vitamin A and C or selenium to protect yourself against cancer,
heart disease or signs of premature ageing. There is some scientific ‘proof’
that people who have a high level of antioxidants in their diet have a lower
risk of heart disease and certain cancers. That is why the nutritionists say
we should eat at least five portions of fruit and vegetables a day. However,
other studies also seem to suggest that taking those same antioxidants in
pill form may not have the same effect and may even be harmful. Who do you
believe?
Dr Alison Ross, at Cancer Research UK says, “These products don’t seem to
give the same benefits as vitamins that naturally occur in our food.”
The British Heart Foundation agrees. A spokesman saying, “Research does not
support the claim that taking extra antioxidants in the form of supplements
will benefit the heart.”
Let us listen to some experts in the field, and not the label on the multi
vitamin bottle. Catherine Collins, chief dietitian at St George’s Hospital
in London says, “The whole idea that you must meet some vitamin and mineral
target every day of your life is a marketing myth. You can eat lots of fruit
and veg one day and not much the next but over a week you will still get the
right amount of nutrients. There is very little scientific evidence that
there is any benefit whatsoever in taking a daily multivitamin - even in old
people. You cannot exist on a poor diet then shore yourself up with a
multivitamin. The idea that taking high quantities of vitamins will give you
a health boost - like putting premium petrol in your car - is complete
nonsense.”
Dr Toni Steer, nutritionist with the British Medical Research Council’s
Human Nutrition Research in Cambridge, states supplements cannot compete
with real food because when we eat fruits and vegetables the vitamins and
nutrients interact with other chemicals to produce positive effects on the
body. “If these same vitamins are pulled out and isolated in pill form,
there is no guarantee at all that they will have the same effect.”
Another nail in the multivitamin coffin came from the US journal of the
National Cancer Institute which found that men with prostate cancer who took
more than seven multivitamins a week were 30 percent more likely to get an
advanced and fatal form of the disease. This came after a large, though
hotly contested, review published in the Journal of the American Medical
Association which found that people who took antioxidant vitamin tablets
(particularly vitamins A and E, and beta-carotene) were more likely to die
earlier than those who did not. Oops! That isn’t something you will read on
the label of the multivitamin bottle.
Let’s look at the old Vitamin C to ward off the common cold, as proposed
many years ago by Linus Pauling. Common claim: one-gram doses will ward off
or even cure the common cold. Reality check: the human body can absorb only
500 milligrams of vitamin C and will excrete the excess. Vitamin C reduces
the average length of a common cold from five days to four and a half - if
you are lucky. Finally, do I take multivitamins? No.
