B
You know eating fruit and vegetables does good .
But do you know it can also make you look good? People who increased their
intake over just six weeks developed a healthy glow and appeared more
attractive, researchers found . Scientists at St Andrews University found eating
them slightly increased yellow and red pigments in the volunteers' skin. They
monitored the food intake of 35 people and took pictures of their faces, arms
and hands using a sensitive camera at the start, and after three and six weeks.
Increasing their intake of greens by 2.9 portions a day was found to make the
person look more healthy and an extra 3.3 portions could enhance their
attractiveness, when their photographs were rated by others.
Fruit and
vegetables are rich in carotenoids (类胡萝卜素)，which are known to protect against
cell damage from pollution and UV rays, and can also prevent age-related
diseases including heart disease and cancer. But while it was known eating
extreme amounts of certain vegetables such as carrots could turn skin orange ，it
was not known a small increase was perceptible(被觉察）to others - and was seen as
appealing.
A camera measured changes to the skin's redness, yellowness and
lightness, and found it significantly changed in people who naturally increased
their intake. These changes were not evident in three weeks. Using light
sensors, the researchers showed these red and yellow hues were linked with the
levels of carotenoids in their skin. There are hundreds of carotenoids but those
thought to have the most dramatic effect are lycopene(番茄红素)-which gives tomatoes
and red peppers their red colour - and beta-carotene found in carrots as well as
broccoli, squash, and spinach. Skin colour is also affected by chemicals called
polyphenols（多元酚)，found in apples, blueberries and cherries, which cause blood
rush to the skin surface.
