Quinoa’s Excellent Nutritional and Functional Properties

Lillian Abugoch James of the University of Chile reported on the composition, chemistry, nutritional and functional properties of quinoa. She cited the pseudocereal’s “remarkable nutritional qualities” including its high protein content (15%), “great amino acid balance,” and “notable Vitamin E content.” Beyond its nutritional profile, Abugoch recommends quinoa to food manufacturers because of its useful functional properties, such as viscosity and freeze stability.

Quinoa Possible Dietary Aid Against Diabetes

Scientists at the Universidade de São Paulo in Brazil studied ten traditional Peruvian grains and legumes for their potential in managing the early stages of Type 2 diabetes. They found that quinoa was especially rich in an antioxidant called quercetin and that quinoa had the highest overall antioxidant activity (86%) of all ten foods studied. Coming in a close second in antioxidant activity was quinoa’s cousin, kañiwa. This in vitro study led the researchers to conclude that quinoa, kañiwa, and other traditional crops from the Peruvian Andes have potential in developing effective dietary strategies for managing type 2 diabetes and associated hypertension.

More Protein, Minerals, Fiber in Quinoa

Anne Lee and colleagues at Columbia University’s Celiac Disease Center found that the nutritional profile of gluten-free diets was improved by adding oats or quinoa to meals and snacks. Most notable increases were protein (20.6g vs 11g) iron (18.4mg vs 1.4mg, calcium (182mg vs 0mg) and fiber (12.7g vs 5g

Kañiwa's Healthy Components

Researchers in Peru studied kañiwa, a native Andean pseudo-cereal that is a cousin of quinoa, to determine its potential to contribute to health. They found that kañiwa is rich in total dietary fiber and lignins, with high antioxidant activity. Moreover, they found that kañiwa had good functional properties, making it attractive for food processing.

Quinoa, Oats, and Buckwheat: More Satiating

A University of Milan study compared buckwheat, oats, and, quinoa to see if any of them showed promise in helping with appetite control.  In three experiments – one for each grain – subjects’ satisfaction and subsequent calorie consumption were compared, after eating the study grain and after eating wheat or rice. All three study grains had a higher Satiating Efficiency Index (SEI) than wheat or rice; white bread was in fact lowest in appetite satisfaction. Unfortunately, even after feeling fuller from eating the study grains, the subjects did not cut their calories at the next meal!
