Yes, this is something which is not publicised enough. There seems to be an increase in breast cancer and the thinking is that aluminium in anti-perspirants may be a contributing factor. It also seems to be linked to senility. Eating oats is supposed to help flush aluminium out of the body, but I don't know if it's true.Odd that you mentioned aluminum cookware Holly. Some years ago anti-perspirents (not deodorants) were suspected of contributing to Alzheimer's because they contain aluminum. Don't know if they still do.
