So it turns out eating too many carrots really can change your skin colour, though perhaps not in the way you think. A study by the journal PLoS ONE suggests that eating more fruit and vegetables gives your skin a healthy glow, which in turn makes you more attractive to others.

Scientists at the University of St Andrews in Scotland monitored 35 individuals and their food intake over six weeks. Subjects who ate larger quantities were rated had higher levels of skin redness and yellowness, and were also rated as more attractive when judged in a psychophysical trial.
The big lesson? If you eat more than three portions of fruit and vegetables a day, you'll look healthier, and if that rises to four, you'll look more attractive. You should eat more than that in any case, but this provides additional motivation. Hit the link for the full study, which will let you overdose on the word 'carotenoid'.
