Hi HN! My family has a history of IBS. For those not aware, a diet low in a class of carbs called FODMAPs is among the most effective treatments for IBS. Following a low-FODMAP diet can be really difficult.
I made a database that estimates detailed FODMAP content for ~3M mass-produced foods. It infers product ingredient composition based on FDA/USDA data and assigns FODMAP content.
Let me know if you have any feedbacks or questions. Hopefully it is useful!
