Is Onion powder Low FODMAP?
Onion powder is high FODMAP. It's best avoided during the elimination phase.
Serving thresholds
| Serving | FODMAP level | Data quality |
|---|---|---|
| ½ tsp (1 g) | High | Lab-tested |
Thresholds are per sitting. FODMAP load stacks across a meal — two “low” servings of different foods can still add up.
Which FODMAPs are in onion powder?
During reintroduction, test the group above one at a time — tolerating onion powder depends on your personal threshold for Fructans, not on the food itself.
Good to know
Onion powder is concentrated fructans — treat as high at any culinary use.
Where these numbers come from
- Peer-reviewed paper: Muir JG et al. (2007) Fructan and free fructose content of common Australian vegetables and fruit. J Agric Food Chem 55(16):6619–27.
- Peer-reviewed paper: Varney J et al. (2017) FODMAPs: food composition, defining cutoff values and international application. J Gastroenterol Hepatol 32(S1):53–61.
Phase derives serving thresholds from published research and food-composition data so every number is auditable.
