(NaturalNews) Many of us already know that eating fruits and vegetables makes us healthy and energetic. We also know from experience that food and beauty are related. Now we have further evidence from research from University of St. Andrews in the UK that fruit and vegetable intake is also associated with healthy glowing skin.
Carotenoids make your skin glow
According to the research published recently in the American Journal of Public Health, carotenoids in the fruits are responsible for the healthy skin glow. Carotenoids are the red, yellow and orange pigments found in fruits and vegetables.
Lycopene, which is a carotenoid in tomatoes and red peppers, provides the red pigment. Beta carotene, which is a carotenoid in carrot and green leafy vegetables, provides the yellow pigment. These carotenoids deposit under the skin and provide several health benefits.
Beauty is linked to fruit and vegetable consumption
In this study, the scientists followed the dietary patterns of 35 students over a period of six weeks. The group did not use any make-up. They also did not get any significant UV ray exposure from the sun or self-tanning machines recently.
These students filled out food frequency questionnaires which provided scientists data around fruit and vegetable consumption. Potatoes were not counted as vegetables in this study.
They recorded the change in skin color and compared perceived attractiveness among these students.
At the end of the study, they found that students who ate more fruits and vegetables had a healthy golden skin. On the contrary, students who reduced the amount looked less attractive by the end of the study.
Skin tone becomes attractive with as little as three additional portions a day
You do not have to gorge yourself with lots of fruits and vegetables for a long period of time. Adding just two extra portions had a noticeable effect on attractiveness within a period of six weeks.
To be precise, eating additional 2.91 portions per day would make you look healthy. Eating additional 3.3 portions of fruits and vegetables would make you look attractive.
On average, one portion of fruit or vegetable is equivalent to 80g. For example, one apple, banana or orange will count as one portion.
Although this study focused on the link between the change in skin tone from carotenoids and attractiveness, previous studies showed that fruits and vegetables have several vitamins and minerals which improve skin health and slow down the aging process.
This study has some limitations because all of the volunteers in the study were Caucasian. So the scientists suggested that another study may be needed to determine if the effect is the same for non-Caucasians as well.
