I’m just going to pop another vitamin pill
So you want to live to be 110? Is the answer multi
vitamins? The answer, if you believe the articles about megavitamins, is in
your local health food store. The answer, if you believe me, is none of
those things.
Now longevity is a very difficult subject to research. So you live to be
100, how do you prove that something (other than genetics) was going to get
you there anyway.
Have you looked at census figures for the life expectancy in different
countries? Before you start “Googling”, Thailand doesn’t do too well at
number 76 with male life expectancy at 71.4. Countries at the top of the
list are Monaco, Japan and Andorra. Consult your travel agent for plane
flights today!
However, staying at home, 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
are some scientific results that show 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!
The British Heart Foundation says that research does not support the claim
that taking extra antioxidants in the form of supplements will benefit the
heart.
But surely, if this were the case, why do so many people pop the
multivitamin pills? We know we need vitamins, and some of us may have poor
diets. Replenishing the stores is then surely ‘good medicine’?
Let us listen to some experts in the field, and not the back of the cereal
box. 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 on 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 back 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.
Do I take multivitamins? No. And I am going to live to be 110 (or die in the
attempt).
