The article says that meat diet people smelled worse than'non-meat diet, but it also said "But the same study suggests that people consuming diets with a little bit of fat, meat, egg, and tofu intake were also associated with more pleasant-smelling sweat. Carb-heavy diets produced the least sexy of scents.".

A lot of the vegans I know (a lot! I live in boulder) have a carb heavy diet.

Any way. The point isn't even about diet because diet is just one factor in body scent.

"has been researched" is doing a fair bit of work, although technically correct.

So has transmutation of metals.
