Actually, I see silicon was recently added to the list of essential trace elements, along with boron, chromium, manganese, nickel, tin, vanadium, molybdenum, arsenic, lithium, aluminium, strontium, and cesium. See http://www.fao.org/docrep/U5900t/u5900t05.htm I assume the silicon would typically be ingested as silicates rather than silica, but the similarities are enough (crystal structure etc) that I think we can forgive the layman confusing the two. BTW, I was also surprised! :-) -K ------------------------ Yahoo!
