OK, I read "Prevention" magazine, and long ago, there was an article "Take Zinc, Don't stink!" or something like that. It claimed that at least some obnoxious foot odor was due to a lack of zinc in the diet. Zinc suppliments are cheap- I'd give it a try. Zinc is also necessary for healing, and as a diabetic (diabetics heal slowly) I take it. Another area it is supposed to help in is gray hair! I'm 59 and my hair is mostly dark-just a few sparkles here and there- but that might be those Cherokee genes doing their magic! lol - Granny
