According to a study by the Department of Psychology at the Macquarie University in Sydney, Australia, women prefer the body odour of men who eat a diet rich in fruit and vegetables.
The experiment involved rounding up a group of healthy young men and testing how much fruit and veg they ate by using a spectrophotometer on their skin, which is an instrument which detects how many cartenoids are present. People who eat a higher amount of fruit and veg have more cartenoids in their skin.
