This image is the result of compiling all of those photos together (creepy, right?) The guy at the top was given beta-carotene and the guy on the bottom got the placebo. The researcher recruited 66 straight, white women to rate each photo based on both attractiveness and how healthy they think the guy in the photo looks. While taking the supplements didn't actually make these guys healthier, according to researchers, it did make them look healthier and therefore more attractive to the women rating these photos.
