for adaptation and growing of quinoa cultivars with optimal nutritional values. The strong positive correlations between the
phenolics and the antioxidant activities warrant further studies on the bioaccessibility, bioavailability and mechanism of action
of these compounds and betacyanins on biomarkers related to health risks. Investigation into the bound phenolics, i.e. the nonextractable phenolics and their role in vivo is also a future research direction.
