What to know about 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
