Olivia Munn's Anti-Aging Tip? Eat This Delicious Purple Vegetable

The star's beauty secret is totally tubular.

When X-Men: Apocalypse star Olivia Munn dishes about what she's eating, drinking, slicing, mashing or blending, her fans and even just quasi-fans tend to listen up. For one thing, she looks fantastic, especially after ditching the hard-core diet she had to go on for the film. For another thing, she can kick a lot of butt thanks to training regimens that would shred mere mortals like us. But the real reason, we suspect, is that Olivia gets a lot of healthy and beauty mileage out of simple, easy-to-prepare ingredients that happen to taste really good.

We've already learned that she drinks homemade almond milk for breakfast—not earth-shatteringly original, but rich-tasting and nutrient-packed and simple to DIY at home—but it turns out she's got a food-related solution to wrinkles too. So what does Olivia do to keep her skin fresh, glowy and (with any luck) age-proof? She eats Japanese sweet potatoes. 

These relatives of the more common sweet potatoes found stateside have purplish skin, golden flesh and a drier texture, and they're fiber- and vitamin-rich. As Olivia told New York magazine's The Cut, she got the idea to eat these potatoes daily after watching a Connie Chung report about Yuruzihara, Japan: "It’s called the 'City of Long Life,' where there are 80 and 90-year-olds with no wrinkles, who do hard labor four to five hours a day. In this area where they live, they can’t grow rice, so they grow these certain potatoes: Japanese root potatoes and Japanese sweet potatoes. They're high in hyaluronic acid."

She buys them at a Japanese market and eats them for "dessert" daily, cutting them into inch-thick slices, sprinkling them with cinnamon and olive oil, and roasting them in the oven. She says she noticed an immediate effect as soon as she started the daily sweet-potato trick. 

"Usually, in the morning, I would get the pillow creases [on my face] and rub them out with lotion," she told The Cut. "Now, after a month of doing the potatoes every single day, the line would be gone as it was when I was younger. I know there are vitamins or supplements with hyaluronic acid, but I didn’t feel like I saw as much of a difference as I did getting it from the natural source." 

US Weekly talked to New York City plastic surgeon Jennifer Levine to get her take on ingesting hyaluronic acid via potatoes: "The health benefits of consuming these potatoes could be great, but their effect on antiaging would be very small at best," Levine said. "Ingesting the acid would cause it to break down in the digestive system, and it wouldn’t get to areas such as the face in high enough quantities to cause a real difference."

But subjects in the Connie Chung report swear by the stuff:
