Red Berries
Strawberries and raspberries can help keep your stomach from feeling like a balloon, because they're low on the list of gas-producing foods containing FODMAPs.

Bok Choy, Fennel and Other Veggies
While bok choy is technically a member of the cruciferous vegetable (aka cabbage) family, the hearty green won't make you feel uncomfortably stuffed in the way some other cabbage can (savoy cabbage, for instance, is a high-FODMAP food, while bok choy is a low-FODMAP one). Other low-FODMAP veggies you may not already be eating include fennel and spaghetti squash.

This root has a reputation for being able to reduce nausea and vomiting, and it also appears to relax the digestive tract, so food can move through comfortably without getting backed up.

Yogurt may be the best-known source of probiotics—the friendly live bacteria that help maintain a healthy gut—but there are dozens more that also help displace bad bacteria in the gut. Among them are fermented foods such as kefir, kimchi, sauerkraut and many pickles.
