Is Buttermilk Low FODMAP?

Serving thresholds

Thresholds are per sitting. FODMAP load stacks across a meal — two “low” servings of different foods can still add up.

Which FODMAPs are in buttermilk?

During reintroduction, test the group above one at a time — tolerating buttermilk depends on your personal threshold for Lactose, not on the food itself.

Good to know

Buttermilk retains lactose despite culturing — high at half-cup or larger serves.

Where these numbers come from

• USDA food composition: USDA FoodData Central — composition database (public domain).
• 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.
