Quinoa
A seed disguised as a grain — with complete protein.
Quinoa is technically a seed, not a grain, delivering complete protein with all essential amino acids — unusual for plant foods. It is naturally gluten-free and rich in fibre (5g per cup cooked), saponins with immune-modulating properties, and polyphenols that feed beneficial gut bacteria. Red, black, and white quinoa each offer slightly different polyphenol profiles.
Why it matters
Complete Protein
All 9 essential amino acids — 8g protein per cup, rare among plant foods.
Gluten-Free
Naturally gluten-free seed — suitable for coeliac and gluten-sensitive individuals.
Diverse Polyphenols
Red, black, and white varieties offer complementary polyphenol profiles.
Saponin Immunity
Natural saponins modulate immune responses via gut-associated immune tissue.
How to eat it
Use as a grain bowl base with roasted vegetables and tahini. Add to salads with herbs, lemon, and olive oil. Cook as a porridge with milk, cinnamon, and blueberries. Use quinoa flour in baking for added protein and fibre.
Quinoa fibre and polyphenols have been shown to increase butyrate production in the colon while its saponins demonstrate immunomodulatory effects on gut-associated lymphoid tissue.
