The Associated Press report that grapefruit makes women appear younger.

A study by the Smell and Taste Institute in Chicago was conducted to determine what makes a women smell young. Institute director Dr. Alan Hirsch reportedly smeared several middle-aged woman subjects with broccoli, banana, spearmint leaves, lavender and grapefruit.

When they were put to the test, a panel of men, grapefruit prevailed.

According to Dr. Hirsch, the male volunteers cited those women with the grapefruit scent up to six years younger than their actual age.

The adverse effect does not necessarily work on men.
