 The reason. the peacock looks like this  and the peahen looks like this, is because of sexual selection. The females prefer males with the most elaborate displays. How does this make sense evolutionarily? How can appearance offer insight into the health of a potential mate.

Having such ornate, excessive plumage is risky. The poor peacock can hardly get off the ground. And this is hardly effective camouflage against predators. And so the fact that the peacock could survive despite such costly ornamentation offers a sense of how robust the bird’s genetics must be. So natural selection might favor females attracted to that sort of thing.

So are you just born attractive or not? Well some species use diet to increase their sexual attractiveness.  Great tits prefer carotenoid-rich caterpillars  which play an role in plumage pigmentation; their breasts become brighter yellow, which is more attractive to potential mates, and a signal of how good they may be at procuring food and is a reflection of their health status, since yellow carotenoids like lutein are so health-promoting. So scientists wondered if the same phenomenon could be found in the human species.

 Published in the International Journal of Primatology, “Facial skin coloration affects perceived health of human faces.”  “The face plays a significant role in human interactions, including mate choice.” So the researchers took digital photographs of caucasian men and women and allowed people to turn a dial to manipulate various color values until they came up with what they perceived to be the healthiest looking color, and both men and women preferred increased yellow, the proverbial golden glow.  In other words, "greens to be gorgeous."

 “We suggest that the healthy appearance of skin yellowness may be attributable to dietary carotenoid deposition in the skin. This suggests that carotenoids, which are involved in health signaling and sexual selection in many species of birds and fish, may also affect the appearance of health in humans.

 In fact “It is a popular view that suntanning enhances the healthy and attractive appearance of Caucasian faces, but this research suggests that any benefit to health appearance from tanning is due to the associated increase in skin yellowness, and that if you separate it out people actually prefer the lighter but yellower skin, so better than a tanning bed to improve our healthfulness and attractiveness is a bed, of greens.

    Do you have any idea of which carotenoids in particular may have this effect? Thanks!

    • Toxins

      If your looking for good whole plant food sources of carotenoids, orange flesh sweet potatoes, greens and carrots can provide more then enough carotenoids to see this effect.

    Great tits?

    This is giving me pause…I have no desire to have orangy/yellowy/tan skin…particularly on my face. What about the coveted alabaster in centuries past…. maybe the yellowness of the skin was chosen in these studies because of changed in cultural preferences.

  • Nikky

    Anything special for facial pigmentation and melasma?

    Look, this is serious. If it becomes known that eating healthy will make you more attractive, then we may well have the key for adolescent dietary improvement that could well alter the health profile of generations to come. Teens are immortal. At least I was at that age but being more attractive to women. WOW!
    I went with WFPBD for all the mundane things like avoiding arthritis, cancer, heart disease, et cetera. Had I known sooner about becoming a “babe magnet” I almost certainly would make it to 100+….
