The impact of quinoa bioactive compounds on gut health

By Hugo Francisco de SouzaMar 4 2024Reviewed by Benedette Cuffari, M.Sc. In a recent study published in Frontiers in Nutrition, researchers review the beneficial impacts of Chenopodium quinoa and its bioactive compounds, particularly its effects on intestinal microflora.

Quinoa is becoming increasingly popular, especially among health- and fitness-conscious individuals, as it is a rich source of protein, fat, vitamins, minerals, fiber, and other bioactive compounds. About the study The present study reviewed 85 scientific publications evaluating the biochemical composition of quinoa, its nutritional benefits, and the efficacy of its bioactives in improving intestinal health. The individual roles of quinoa-derived saponins, polyphenolic compounds, polysaccharides, and biopeptides in improving gut microbiota outcomes were also discussed.

Metabolomic studies have found that saponins obtained from quinoa digestion can improve the metabolism of some vitamins and alter the ammonia cycle. However, caution must be taken when deciding upon supplementation dosages, as high concentrations of quinoa-derived saponins have been shown to be toxic in rat models.

Polysaccharides Related StoriesMost quinoa-derived polysaccharides are prebiotics capable of increasing the proportion of beneficial probiotic Bifidobacteria and Collinsella bacteria. In combination with quinoa dietary fiber, quinia polysaccharides effectively modulate SCFA concentrations and reduce weight in high-fat diets characteristic in hyperlipidemia.
