Quinoa

Overview

Quinoa is a pseudograin providing complete plant protein, magnesium, and when fermented in sourdough, can produce GABA through specific bacterial strains. Quinoa has a DIAAS score of 83-87, indicating high protein quality with complete amino acid profile (lysine marginal). Quinoa sourdough offers both very high nutrients (due to the quinoa) and a high GABA profile. Quinoa is mentioned as a source for choline support, important for vegans.
