A comprehensive reference guide of low-FODMAP foods and their safe serving sizes, compiled through my personal research and experience managing digestive issues.
Last updated: May 31, 2026
This guide was accumulated over many years from a wide variety of sources. In many cases the original sources are no longer known or traceable. While I've done my best to ensure accuracy, this information is not guaranteed to be 100% accurate or up-to-date.
FODMAP research continues to evolve, and the agreed-upon acceptable serving sizes for any given food can change over time and vary from source to source. What one source lists as safe may differ from another. Individual tolerances also vary considerably from person to person.
Always consult with a registered dietitian or healthcare provider for personalized guidance. This is shared as a reference tool that helped me—use it as a starting point for your own research, not as a definitive medical reference.
