Are Japanese sweet potatoes the fountain of youth?

Can Japanese sweet potatoes take the place of a plastic surgeon? Actor Olivia Munn thinks so.

Perhaps looking to deflect recent speculation that she’s had cosmetic work done, the “X-Men: Apocalypse” star took to Instagram Tuesday to reveal the secret behind her radical change of appearance.

“Japanese potatoes … help keep wrinkles away,” she wrote.

Munn has said she eats a baked one every day. The purple tuber, known as satsuma-imo, is similar to a regular sweet potato, high in antioxidants and healthier than a white potato. The satsuma-imo trumps the Idaho white with fewer carbs (24 grams vs. 37 grams) and calories (113 vs. 170). But a beauty secret?

“I don’t think they have anything magical about them,” says Lisa Moskovitz, registered dietician and CEO of the NY Nutrition Group. “If you ate a lot of other things [containing skin-protecting anti-oxidants, such as berries or salmon], you’d be getting the same benefits.”

Wrinkles are also the result of many factors not related to diet, including stress and lifestyle, Moskovitz says.

So if you’re looking for a real surefire way to stay youthful, follow another age-old Hollywood secret: Lie about your age.
