Is Watermelon Low FODMAP?

High FODMAP

Avoid during elimination. Save for a structured reintroduction challenge.

Safe serving

No safe serving during elimination

FODMAP group responsible

  • Excess fructose — Monosaccharides. A problem only when fructose outweighs glucose, as in honey and apple.
  • Fructans — Oligosaccharides. Wheat, onion, garlic. The most common trigger and the hardest to avoid.
  • Mannitol — Polyols. Cauliflower, mushrooms, celery, sweet potato.

Why

One of very few foods high in three FODMAP groups at once — excess fructose, fructans and mannitol. It reliably causes symptoms and is worth treating as a hard no.

What to use instead

  • Cantaloupe melon

    Low FODMAP at 90 g, and the one melon that survives elimination. Honeydew is similar.
