A working list for a first shop after diagnosis, organised the way a supermarket is. The few things in each aisle that need checking are called out.
The perimeter of a supermarket is almost all gluten free without any labels involved: produce, meat, dairy and fish. Most of the anxiety, and most of the cost, lives in the centre aisles. Building meals from the perimeter and treating packaged food as the exception is safer and much cheaper than replacing every wheat product with a gluten-free version of the same thing.
All fresh fruit and vegetables are gluten free. There is no exception worth learning.
In a shared household these matter more than any single food.
Point CiCi at the barcode on anything on this list and get this same reasoning in about two seconds, plus the carbs and whether it has been recalled. 360,000+ packaged foods are already read and waiting.
Each guide covers a whole aisle and explains the mechanism, which is more portable than any list of names.
This site answers the question you knew to ask. The app answers the one you didn't: the barley malt in a rice cereal, the wheat starch in a gummy. Scan the barcode, or photograph the panel when the barcode isn't in any database, and CiCi shows which words on the label produced the answer.
14 days free, then $29.99 a year. Cheaper than Fig, and it does what three separate apps do. This website stays free forever either way: every answer on it, permanently, with no account.
