Stars in Hollywood have all kinds of secrets for keeping up appearances, whether it鈥檚 drastic a la Miranda Kerr鈥檚 leech beauty treatments or simple like Kourtney Kardashian鈥檚 apple cider vinegar聽smoothies. Now, Olivia Munn just spilled the beans on what her healthy snack is (and, spoiler alert, it鈥檚 not beans).

Munn believes she鈥檚 found just the right food to help her stay fit, and it鈥檚 none of the standbys you鈥檇 expect. Instead, the Office Christmas Party actress snacks on 鈥 get this 鈥 beef jerky.

In an interview with US Weekly, the 36-year-old said that she carries it with her constantly. 鈥淚t鈥檚 a really easy go-to snack that has protein and it鈥檚 really low in sugar and carbs because my other option is protein bars,鈥 she revealed. 鈥淚 was eating those for a while and that just puts on weight. They鈥檙e loaded with sugar and carbs.鈥

It鈥檚 not the only food weapon in her healthy arsenal, either. She revealed over on Instagram last year with a lengthy post that showed Munn鈥檚 physical transformation over the course of a year. 鈥淎sk anyone who knows me and they鈥檒l tell you I love research,鈥 she wrote. 鈥淐onvinced that there鈥檚 got to be natural, healthy ways (i.e. not only the rich and connected can get it) to keep your skin from aging, I do lots of research.鈥

And that research led the X-Men: Apocalypse actress to her go-to anti-wrinkle food: Japanese sweet potatoes. 鈥淛apanese potatoes that are high in hyaluronic acid help keep wrinkles away,鈥 she revealed. 鈥淟ook up this video 鈥楥onnie Chung Yuzihara鈥 to learn all about it. There are hyaluronic pills and vitamins but I think the best way to get it in your system is by eating them in foods that naturally have them.鈥

And there you have it, folks! Beef jerky and Japanese sweet potatoes for the win. Who knew?!
