Vitamin Overdose

摘要

My mother always told me that too much of a good thing can be bad for you. If I didn't already believe her, last week's bulletin from the Institute of Medicine would have persuaded me. The institute, an arm of the National Academy of Sciences, made headlines last year with an alarming report about how often medical mistakes are made in hospitals. This time it tackles vitamins C and E and other so-called an-tioxidants, and it warns against ingesting too much of them.
