(Newser) – Women who eat one to two apples a day experience a better sexual quality of life than women classified as having “no regular apple consumption,” according to a new study in the Archives of Gynecology and Obstetrics. Scientists followed 781 Italian women aged 18 to 43 with no history of sexual disorder and who were not taking prescription meds or suffering from depression, and learned that those who eat apples regularly had better “lubrication and overall sexual function.”

The researchers didn’t establish causation—it’s possible, for instance, that women who eat more apples are healthier overall, which contributes to better sexual function. But, like chocolate and red wine, apples contain polyphenols and antioxidants, which can increase blood flow to the genitalia, as well as phloridzin, a type of estrogen similar to the female sex hormone estradiol that improves vaginal lubrication, reports the Huffington Post. Some of these benefits may lie only in the peel of the apple, and researchers say it “might be interesting to evaluate” what role apple peels play in female sexuality, reports Salon.
