Nanaimo Bar and the low FODMAP diet
Nanaimo bars layer a no-bake crust, custard filling, and chocolate topping into a dense Canadian dessert. The crust introduces fructans from graham crackers, while the custard contributes lactose. The chocolate topping adds minimal additional triggers depending on purity. This layered format concentrates multiple FODMAPs into each square. Careful ingredient substitution and strict portion limits are necessary.

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 layered structure combines wheat fructans, dairy lactose, and sweetener fructose into a concentrated bite. You can safely recreate this dessert using certified low-FODMAP crumbs and lactose-free custard powder. Always verify chocolate topping relies on pure cocoa rather than polyol diet varieties. Chill bars thoroughly before cutting to prevent crumbling and maintain accurate portion control.
