Is wheat flour OK for SIBO?

It depends on how much, and here is why

The SIBO rule set applies the same FODMAP scan, so wheat flour flags identically. Munchable also carries a standing note that no SIBO-specific diet has a strong evidence base.

On a real product, the reason Munchable shows reads: Contains fructans, a FODMAP; the amount may be small

What Munchable checks for SIBO

• The full FODMAP scan: fructans, GOS, polyols, excess fructose and lactose
• Whether each source is a main ingredient or a minor one
• A standing banner on every SIBO verdict about the state of the evidence

The full reasoning, and the evidence behind it, is in the SIBO guide.

The catch with reading labels yourself

Knowing that wheat flour 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.
