First up, let’s talk about carbonation. Those tiny, playful bubbles that make soda so satisfying? They’re literally carbon dioxide gas trapped in liquid. When you chug them, you swallow air along with the fizz, and your gut has to deal with it.

Now, onto the artificial sweeteners that make diet soda “diet.” Aspartame, sucralose, and their pals are designed to trick your brain into tasting sweet without the calories. But your gut is not easily fooled.

Not everyone reacts this way, but if you’re prone to bloating, your microbiome might be sending you a very loud, gassy signal.
