Eating fruits and vegetables can make you more attractive
Carotenoids are yellow, orange, and red pigments synthesized by plants and algae. They are responsible for the colours in fruits and vegetables, like the redness in tomatoes. When consumed, these pigments are used by many animals to produce brightly coloured displays. Examples range from the orange patches on guppies, the pink feathers of flamingos, the yellow-orange underside of common lizards, to the orange exterior of ladybird beetles.
