The mere sight of chocolate can trigger cravings. So what do you do when you’re surrounded by chocolate peanut clusters, gooey fudge and chocolate-covered cherries this holiday season? Sniff or diffuse some jasmine essential oil. Studies show that smelling jasmine (or other nonfood scents) can curb chocolate cravings. But avoid sniffing sweet scents, such as vanilla-scented candles, which research suggests could increase cravings for sugary treats.
