Vitamins and
minerals are good for us. And if the amounts we get in our food are
good, then taking concentrated doses in a pill must be even better,
right?
Depends. Here's
registered dietician Liz Pearson with what you need to know about supplements.
If you take a vitamin or mineral supplement you're not alone, about
half of Canadians do. There are some things you should be aware of.
First of all remember that there are certain nutrients that can be toxic
in large doses such as vitamin D, iron, zinc and selenium. Also remember
that too much of one nutrient can interfere with the absorption of another.
Too much zinc, for example, can interfere with the absorption of iron
or copper. There are some times however when taking a vitamin or mineral
supplement is a good idea. Strict vegetarians should take a vitamin
b-12 supplement. If you're thinking about getting pregnant, folic acid
will help prevent certain birth defects. Once you are pregnant a prenatal
supplement is a good idea. If you're over the age of sixty a multi-vitamin
is a very good idea. There is also some preliminary evidence that vitamin
E may be beneficial for reducing the risk of heart disease. Always remember
to consult a dietician to determine if you need a vitamin/mineral supplement
and how much you should take. And always remember a vitamin or mineral
supplelenmt can never take the place of food. Food contains a complex
mix of compounds that have never even been put into a pill because until
recently scientists haven't even known they existed.
