Is Tamari Low FODMAP?
Low FODMAP
Tamari is low FODMAP at a serving of 2 tbsp (42 ml) and is generally well tolerated during the elimination phase.
Serving thresholds
| Serving | FODMAP level | Data quality |
|---|---|---|
| 2 tbsp (42 ml) · fermented | Low | Class rule |
Thresholds are per sitting. FODMAP load stacks across a meal — two “low” servings of different foods can still add up.
Good to know
Tamari is a wheat-free soy sauce — same low-FODMAP profile as regular soy sauce at standard serves.
Where these numbers come from
- Derivation note: Fermented soy without wheat; long fermentation depletes FODMAPs. No groups above cutoff at standard culinary serves.
- 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.
