We’re no stranger to using food in the pursuit of beauty. But when we heard that X-Men star Olivia Munn eats a Japanese potato every day to maintain her youthful complexion (wait, what?), we were seriously intrigued. So we turned to registered dietitian Robin Barrie Kaiden for her take on the tubular trend.
First, some background: Native to Japan (but also grown in the U.S.), these purple potatoes have a texture similar to okra and can be cooked just like your standard spud. Munn revealed that she likes to roast hers with olive oil and cinnamon and enjoy it as a dessert. (Here's an easy recipe from the blog This Week for Dinner.) But will chowing down on one a day, like she does, give us that Hollywood glow?
“Japanese sweet potatoes are high in fiber,” says Kaiden. “Fiber improves digestion, helps rid the body of waste and decreases inflammation, all which is great for the skin,” she adds. They’re also nutritional powerhouses when it comes to vitamin C, which “protects the skin from environmental pollutants and toxins, as well as aids in collagen production.”
And that’s not all. Kaiden also tells us that these purple tubers contain almost 400 percent of your body’s daily needs of vitamin A, which helps promote cell turnover and prevent acne. (But since vitamin A is fat soluble, you’ll want to eat these guys with a healthy source of fat, like olive oil or avocado, to aid absorption.)
