Does onion cause reflux?
For a lot of people, yes, and here is why
Munchable treats onion as a common reflux trigger. Individual responses vary a great deal, and the guideline evidence for trigger foods is low certainty, so Munchable raises a caution and never an avoid on this axis.
On a real product, the reason Munchable shows reads: Contains onion, a common reflux trigger for some people
What it is called on a label
Onion is also printed as onions. Munchable recognises all of these as the same ingredient, which is the point of scanning rather than reading: the wording changes between brands and the rule does not.
What Munchable checks for GERD and reflux
- Chocolate and cocoa
- Mint, peppermint and spearmint
- Tomato, including concentrates and purees
- Citrus and citrus juices
- Onion and garlic
- Chilli, pepper and other heat
- Caffeine and carbonation
- High fat per serving, which delays stomach emptying
The full reasoning, and the evidence behind it, is in the GERD and reflux guide.

The catch with reading labels yourself
Knowing that onion is a problem is the easy part. Finding it is the hard part: it hides behind wordings that do not look like it, it matters more near the top of the list than the bottom, and a product you have bought for years quietly reformulates. That is the job Munchable does in the aisle, in about a second, from the barcode.
Check it in the shop, not at home
Point your phone at the barcode and Munchable reads the ingredients list for you, before it goes in the basket.
