Skeptics love to hate CAM. And often, with good reason. Alternative medicines or medical treatments, as is often pointed out, become “mainstream” when the available science suggests that they work, so it is almost axiomatic that “alternative” means “unproven” and it is probably almost always true that the kinds of things that end up as “alternatives” come from sources with poor track records. For instance, one of the most common forms of alternative medicine used over the last several decades is Extra X where X is some substance we know the body uses, and that we know a deficiency of is bad. The idea is that if something is good at a certain level, loading it on by a factor of anywhere from two or three to several hundred over the usually consumed amount must be REALLY good. If a substance is used in the body for something we like … an immune system function, tissue repair, muscle energetics, etc. … then consuming vast quantities of it MUST be good. And, in some cases, this turns out to be true. There are times when consuming huge quantities of potassium is medically indicated, for instance. But this does not mean that a daily intake of seven or eight hundred bananas is a good idea. It turns out that loading huge quantities of vitamins and minerals has very little or no positive effect and it can be rather harmful in some cases. (Though there may be some exceptions.)
