The gluten-free craze has hit Chick-fil-A.
The fast-food chicken chain announced Monday that it is now serving a gluten-free bun at restaurants nationwide.
Its new bun is made with quinoa and amaranth and sweetened with molasses and raisins. It contains 150 calories and costs an additional $US1.15.
Chick-fil-A is looking to capitalise on a diet trend that has swept the nation.
According to a study done by JAMA Internal Medicine in 2016, one in five people in the US have eliminated gluten from their diets. Only 1 per cent of the population actually has been diagnosed with a celiac disease, an autoimmune disorder that prevents people from eating gluten.
Chick-fil-A will be one of a few fast food restaurants to offer a gluten-free bread alternative. Shake Shack also serves a gluten-free bun.
