A recent study found that women preferred the body odor of men who ate a lot of fruits and vegetables, whereas men who ate a lot of refined carbohydrates (think bread, pasta) gave off a smell that was less appealing.
From an evolutionary perspective, scientists say our sweat can help signal our health status and could possibly play a role in helping to attract a mate.
Men who ate a lot of meat did not produce a sweat that was any more — or less — attractive to women. But meat did tend to make men's odor more intense.
Stephen and his colleagues also had the men in the study complete food frequency questionnaires so they could determine the men's overall patterns of eating. Then the men were given clean T-shirts and asked to do some exercise.
Afterward, women in the study were asked to sniff the sweat. (Note: The methodology was much more scientific and precise than my breezy explanation, but you get the picture.) "We asked the women to rate how much they liked it, how floral, how fruity," and a bunch of other descriptors, explains Stephen.
