I have Celiac Disease and let me tell you, I would love to see gluten free items cost the same as regular foods. The only thing you apparently can do is to include an itemized list of GF items you’ve bought over the year and include it in your tax return. However, the amount of bureaucracy is probably a great deterrent for people like me to not do this and just eat the extra cost.
