Many people do the wrong thing when they are trying to be healthy.
Vitamins, which maintain and
facilitate the body's various
functions, are an
essential part of our diet. Many people take vitamin
supplements to
guarantee them the _(1)_ daily
allowance. However, recent studies have
suggested that people who take vitamin supplements may be getting too much of a good thing.
Many of the foods we eat already have vitamins _(2)_
added to them. People drinking a glass of orange juice may think that they're only getting a
dose of vitamin C. In fact, they are also getting added
calcium and vitamin D. Breakfast
cereal alone provides more than half a person's daily allowance of some vitamins. _(3)_ these levels with supplements can cause some
nasty side effects.
According to the Office of
Dietary Supplements in the US, too much vitamin A can cause headaches and affect bone
strength. Too much iron can affect the
liver and _(4)_
unpleasant vomiting. Vitamin supplements are not _(5)_ the same
rigorous tests as medicine, which makes knowing what's really in them
problematic. Besides, they are not tested for safety or
effectiveness because they are not considered a _(6)_ for disease.
If you feel that you must take vitamin supplements,
nutritionists suggest taking them in _(7)_ doses. This means that if you take a calcium pill, you shouldn't drink too much milk. They also
advise against excessive intake, such as eating three
energy bars for breakfast and then taking a dose of vitamin A. If your diet is
relatively balanced,
chances are you are already OK where vitamins are concerned.
