Men, Listen Up: Women Like The Smell Of Guys Who Eat A Certain Diet (read the full article hear)
I was greatly entertained by this article A) because it reads so silly but, from a biological and evolutionary standpoint makes perfect sense. And, B) because I just wrote a blog about a very similar health concept. This article talks about women being attracted to the smell of a man who eats a predominately veggie diet over that of a man who eats an abundance of meat. This is an interesting concept because only vegetarian animals have sweat glands that work for temperature regulation. Meat-eating animals, including carnivores and omnivores, may have sweat glands but they generally do not work or only work minimally but not enough to make a different in temperate—this is why you see many animals panting to release heat. So, it makes sense for a species who isn’t built for medium or large quantities of meat, like ourselves, to perspire a not so pleasant (probably nitrogenous) sweat after eating a lot of meat. Omnivores and carnivores are equipped with an enzyme called uricase that breaks down the toxic uric acid (a form of nitrogenous waste) found in all meat. Humans lack the enzyme uricase and instead absorb uric acid back into our body which creates many health problems. Interestingly, studies have been done (only on men) that show uric acid in some human sweat.
Additionally, sexual selection generally dictates that either men compete for their mates, like how male sea lions fight for their territory of all the females, or that women choose, like how male birds are prettier than females because females will choose the prettier males. So, it would make sense that for humans, women would be the more susceptible sex to be impacted by a mans smell. A woman’s biology is built to be attracted to a mate who can give her offspring the best success, which means he must be healthy. Obviously, we are capable of using our brains to think otherwise, but that doesn’t mean our instincts aren’t also in play. If a man was sweating out the uric acid due to eating meat, a woman probably wouldn’t like that smell because it would indicate poorer health. Now, I highly doubt most women are blatantly aware of this smell. I’ve never smelled a man and thought, “he must eat a lot of meat.” Although I have to admit this will probably be on my mind every time I’m around a man now and am definitely going to do my own little experiment to test this out!
What we eat can influence more than our waistlines. It turns out, our diets also help determine what we smell like. 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.
