A research team led by scientists from Jilin University in China discovered that bioactive compounds found in quinoa may have beneficial effects on the gut microbiota and improve cardiovascular health. Research results published In the scientific journal Frontiers in Nutrition.
The researchers’ study is a meta-analysis of 85 previous scientific publications that evaluated quinoa’s biochemical composition and potential health benefits. As a result of analysis, Chinese scientists discovered that the saponins (complex nitrogen-free organic compounds) contained in quinoa have a wide range of biologically important functions.
Saponins derived from quinoa are poorly absorbed in the intestine and have low bioavailability, which contributes to their long retention in the intestine. Thanks to this, saponins can serve as nutrients for beneficial intestinal bacteria, thereby helping to improve the composition of the microflora and work more efficiently. It also turned out that these substances, when digested by quinoa, can improve the metabolism of some vitamins, leading to their better absorption.
Additionally, quinoa proteins have been found to be a natural source of angiotensin-converting enzyme (ACE) inhibitory peptides. It is normally produced in the epithelial cells of the lungs and is detected in small amounts in the blood vessels and kidneys. ACE has the ability to constrict blood vessels, resulting in an increase in blood pressure. Reducing the concentration of ACE in the body has an additional positive effect on the cardiovascular system.
