The Sweet Treat in Your Morning Coffee
Why your gut's not a fan: Artificial sweeteners contain FODMAPs, and that means they're osmotic, pulling water into your intestinal tract and potentially causing diarrhea. And because artificial sweeteners (look for ingredients that end in an "ol", like sorbitol or mannitol) are calorie-free, our bodies don't recognize them as nutrients and don't digest them, says Lisa Ganjhu, MD, a gastroenterologist at NYU Langone Medical Center. That leads to gas and bloating.

How to fix it: If you find that your stomach doesn't feel so great after you get your morning caffeine-and-fake-sugar fix, use small amounts of actual sugar instead.
