以下是墨尔本悉尼文波PTE雅思培训学校整理的原文材料：
Many people love what they consider a suntan’s healthy glow. But the color you get from eating vegetables might be the most attractive glow of all. That’s according to research in the journal Evolution and Human Behaviour. [Ian D. Stephen, Vinet Coetzee and David Perrett, “Carotenoid and melanin pigment coloration affect perceived human health“]
Researchers controlled the diet and evaluated the skin color of 82 participants for eightweeks. Those who ate more fruits and vegetables had a yellower hue to their skin. That tonecomes from carotenoids in the fruit and veggies, which are linked to better immune defensesand reproductive health.
In related studies, the scientists recruited volunteers to look at photographs of 51 faces. Theycould manipulate the colors of the face to increase the darkness or the yellow tones. Theywere asked to adjust the colors until the faces looked to be what the subjects considered themost healthy. And the majority preferred a yellowish tone, like that produced bycarotenoids. This held true for Caucasians in the U.K. and black Africans in South Africa.
The researchers say the preference could be a gauge of vigor—many animals let their healthbe known to potential mates through vibrant coloration. So eat fruits and vegetables if youwant your face to advertise your fitness.
