It seems that ‘Elements in the human body’ is a rather popular high school project and freshman general chemistry assignment (about 4,380,000 Google hits). And most ‘researchers’ are impressed with the fact that oxygen, carbon, hydrogen and nitrogen make some 96 wt%, then comes calcium at ‘low’ 1.5 wt%, phosphorus ‘only’ 0.7 wt%, then ‘trace amounts’ of dozen other elements. Many quote Herman J. Muller (Nobel Price in Physiology or Medicine, 1946):

"To say that a man is made up of certain chemical elements is a satisfactory description only for those who intend to use him as a fertilizer."

I don’t know in which context this was said. However, I believe it was Muller’s reaction to that ‘weight percentage’ type of data presentation. You can’t be aware that chromium participates in glucose metabolism by enhancing the effects of insulin and at the same time present chromium at a linear weight percentage graph - its abundance is about one millionth part of a 1 wt%.
