Key Lime Pie and the low FODMAP diet
Key lime pie combines a wheat graham crust with a tangy condensed milk and egg filling. The crust introduces fructans, while the condensed milk contributes concentrated lactose. The tart lime filling remains low in FODMAPs, leaving dairy and grain as the main triggers. Careful portion sizing and crust modification ensure this pie stays manageable. Commercial bakery versions often add high-fructose thickeners that require checking.

Portion size can change a FODMAP result. Treat this as the context for the range—not a personal tolerance guarantee.
What can change the result?
The dual FODMAP impact comes from the graham cracker crust and the sweetened condensed milk center. You can safely recreate this pie using certified low-FODMAP crust flour and lactose-free condensed milk. Always verify that lime filling relies on fresh juice rather than commercial high-sugar concentrates. Chill pie thoroughly before slicing to stabilize custard and support smoother gastric breakdown.
