What a terrible experiment design. Groups were given Pepsi, Coke, and a control group was given water. That’s not very conclusive evidence for/against any particular ingredient, or carbonation.
False title. They tested Coca-Cola and Pepsi-Cola, not carbonated beverages (which would be seltzer).<p>And they seem to have zero ability to distinguish because the carbonation, the phosphoric acid, or the sugar.
It seems like I've seen quite a bit of people claiming that testosterone levels have been dropping as of late. Can anyone tell me if that's true or not?
