You might have heard of a Low FODMAP diet. Onions are basically the kingpin of FODMAPs—short-chain carbs that are notorious for causing gas. If you have IBS, onions are public enemy number one.
This isn’t about being “allergic.” It’s about your gut being a picky eater. “Sorry, chef, I don’t accept reservations for fructans tonight.”
For some people, a tiny sliver in a stir-fry is fine. For others, even onion powder in a chip is enough to call the gas department.
The Good News: Garlic’s Cousin Is Just as Bad
If you thought onions were bad, just wait until you hear about garlic. It has the same fructan issue. If you are feeling bloated after onion soup, you were probably double-faulted by the garlic bread you ate with it.
Why Onions And Garlic Cause Gas: Understanding The Science Behind
So, what do you do? You don’t have to swear off onions forever. That would be a tragedy. You just need to be strategic. Knowledge is power—and less gas.
Start paying attention to your portion sizes. One tablespoon of caramelized onion is very different from a whole one. Eat slowly. Chew your food like you are mad at it.
