Short answer: Yes — quinoa is low FODMAP at a serving of 1 cup cooked (155 g), according to Monash University. It's one of the safest grains for the elimination phase because it's naturally gluten-free and does not contain fructans like wheat.

Why Quinoa Works on Low FODMAP
Quinoa is a pseudocereal — it looks like a grain but is technically a seed. It contains no wheat, rye, or barley, so it's free of the fructans that trigger IBS symptoms for many people. It's also a complete protein, containing all nine essential amino acids (source).
When Quinoa Becomes High FODMAP
Eating more than 1.5 cups cooked in one sitting can push you into the moderate GOS (galacto-oligosaccharide) range. Stick to a single cup and pair it with proven-safe proteins and vegetables.
How To Cook Quinoa For IBS
- Rinse thoroughly for 30 seconds — this removes bitter saponins that can irritate the gut.
- Use a 1:2 ratio (1 cup quinoa to 2 cups water or low-FODMAP broth).
- Simmer 15 minutes, then rest covered for 5.
- Season with garlic-infused oil (not garlic pieces), salt, and fresh herbs.
