Is Oat milk Low FODMAP?
Oat milk is moderate FODMAP — it can fit a low-FODMAP diet, but only up to 1/2 cup (125 ml). Larger servings are likely to trigger symptoms.
Serving thresholds
| Serving | FODMAP level | Data quality |
|---|---|---|
| 1/2 cup (125 ml) | Low | — |
| 1 cup (250 ml) | Moderate | — |
Thresholds are per sitting. FODMAP load stacks across a meal — two “low” servings of different foods can still add up.
