Not every trigger is FODMAP

Caffeine, alcohol, stress, spicy foods, and high-fat meals can trigger IBS too. FODMAPs are one high-value path to test, not the whole diagnosis.

Track the full plate

A moderate food may be fine alone and rough when eaten with other moderate foods. Use Today's Plate to watch the count.

Move to reintroduction

The goal is not lifelong fear of food. Strict elimination is temporary, then foods return one at a time.
