Is Ranch dressing Low FODMAP?
Ranch dressing is high FODMAP. It's best avoided during the elimination phase.
Serving thresholds
| Serving | FODMAP level | Data quality |
|---|---|---|
| 2 tbsp (30 g) | High | Class rule |
Thresholds are per sitting. FODMAP load stacks across a meal — two “low” servings of different foods can still add up.
Which FODMAPs are in ranch dressing?
During reintroduction, test the groups above one at a time — tolerating ranch dressing depends on your personal threshold for Lactose, Fructans, not on the food itself.
Good to know
Ranch combines buttermilk and sour cream with onion and garlic powder — high in lactose and fructans.
Where these numbers come from
- Derivation note: Buttermilk + sour cream + mayo + garlic powder + onion powder + herbs; lactose and fructan loads above cutoffs at standard 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.
