As an anecdote I gave up antiperspirant and deodorants after suffering rashes and pain in my under arms. I sweat more, but I was surprised to find I actually smell better. Or rather I'm told I smell better. Additionally I discovered that the stains in the underarms of my clothing went away, apparently it's caused by the deodorants. Diet may indeed play a factor, I am vegan. YMMV.
