Why gos food checker matters
Galacto-oligosaccharides (GOS) are carbohydrates found mainly in legumes and some vegetables. They're a FODMAP that can ferment in the gut, causing bloating and discomfort in sensitive people.
- Canned and rinsed legumes are lower in GOS than dried
- Start with smaller portions and build up tolerance
- Some people find beano-type enzymes helpful

Serving size, prep, and portion notes for oat milk
Oat milk is dairy-free but not automatically gut-friendly: it is high FODMAP by the glass because the oats carry fermentable oligosaccharides, so a full latte can bloat people who do fine with a splash. Oats are also naturally gluten-free yet routinely cross-contaminated with wheat, so standard oat milk is not safe for coeliacs unless it is certified gluten-free. The beta-glucan fibre that makes it creamy is exactly what your gut ferments.
Watch for
High FODMAP in a full serving: the oligosaccharides from oats build up past about half a glass and can cause bloating and gas / Cross-contamination risk with gluten, so it is only coeliac-safe if the carton says certified gluten-free, since most oats share milling equipment with wheat / Barista versions usually add oil and sometimes gums for foam, which can bother people who react to added seed oils
