Fennel
This perennial herb offers some serious benefits for your belly. “For centuries, fennel has been used to improve digestion, relieve GI spasms, and reduce bloat,” says Stephanie Middleberg, RD, founder of Middleberg Nutrition in New York City.
You can eat fennel raw or cooked (try sprinkling it on a pizza or making Tomato-Fennel Soup). And fennel seeds have slimming properties, too: In a previous interview, Ann Louise Gittleman, PhD, recommended sipping on fennel tea to de-puff your stomach before a big event.
