Lemon Bar and the low FODMAP diet
Lemon bars feature a shortbread wheat base topped with a tart lemon curd layer. The wheat crust introduces fructans, while the lemon filling remains low in FODMAPs. The butter in the crust contributes minimal lactose depending on the recipe ratio. Careful crust verification and portion control ensure bars stay within safe limits. Most sensitive individuals tolerate a standard piece when wheat intake is monitored.

What can change the result?
The primary trigger in lemon bars comes directly from the wheat flour used in the shortbread crust. You can safely lower the impact by using certified gluten-free baking flour for the base layer. Always verify commercial bars do not contain added high-fructose lemon syrup or polyol toppings. Store bars chilled to prevent crust softening that increases chew time and gas intake.
