Vitamins and Minerals

Life and health are a symphony of chemicals, which must be present in
the
right proportions. Too much is just as bad as too little. Today, everyone
is
worried about getting enough calcium, as if it's impossible to get enough.

This is false and dangerous reasoning. Too much calcium can cause
constipation, irritability, insomnia, headaches, kidney stones, peptic
ulcer,
and psychosis. Why don't the experts who recommend supplements warn
people about the dangers of excess chemicals? Perhaps it's because many of

these experts also sell supplements. A healthy diet is like a good recipe:
you
need the right ingredients in the right proportions. Too much of one
ingredient can ruin your dish, your diet, and your health.
