Toots & Trots / Does it matter?
Flat white with full cream milk or oat milk — does it matter?
Swapping dairy for oat milk removes the lactose risk but replaces it with oat FODMAPs and sugars. For most J-pouchers, the oat swap is still a meaningful improvement — especially if dairy is a known trigger.
Scores use a standard reference serving via the GASP model. Individual tolerance varies.
A small difference — mainly gas.
If you notice wind and bloating, Flat white — oat milk is the gentler pick. If you're tolerating both well, it probably doesn't matter.
