Is Ketchup (standard serve) Low FODMAP?
Low FODMAP
Ketchup (standard serve) is low FODMAP at a serving of 1 tbsp (15 g) and is generally well tolerated during the elimination phase.
Serving thresholds
| Serving | FODMAP level | Data quality |
|---|---|---|
| 1 tbsp (15 g) | 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
A standard sachet or single tablespoon of ketchup keeps fructose under the cutoff. Larger pours stack up — see the large serve entry.
Where these numbers come from
- Derivation note: Tomato + sugar/HFCS + vinegar + salt; fructose load below cutoff at single-tablespoon 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.
