What you eat makes a huge difference to how you smell, and I don't just mean garlic!

This too, It is amazing how chemicals contained in food can pass all the way through ones digestive system, Blood stream, Lungs and skin and then still manage to extrude back into the world.
I am given to understand that most Chinese reckon that Europeans/Americans stink of sour milk. (AIUI, Asiatics are mostly lactose intolerant so while cheeses and yogurts are used as food, raw milk traditionally has not been)
