No carrot a day might keep the suitors away. Researchers at St Andrews and Bristol universities found that people with a slightly yellow skin hue are considered more healthy and attractive. The study reported that in only two months, increased consumption of carotenoids—yellow pigments found in produce like carrots and plums—led to yellower skin in Caucasian faces. The yellower faces were found by test subjects to be more physically appealing. Ian Stephen, one of the scientists involved in the study, which will be published in the journal Evolution and Human Behavior in March, said the link might result in new strategies for persuading young people to eat more produce.
