Newswise — CHICAGO— Got quinoa? If not, you may want to consider adding it to your diet. A recent review article by researchers from Rutgers University, Universidad Arturo Prat and Universidad de Las Américas explained the specific phytochemicals and nutrients that make quinoa so healthy. The study was featured in the July issue of Comprehensive Reviews in Food Science and Food Safety, published by the Institute of Food Technologists (IFT).

1. Protein: Quinoa has a higher protein content than barley, oat, rice and maize1. Due to a property of its storage proteins, quinoa is a safe gluten-free option2. According to the FAO and WHO, quinoa protein can supply over 180 percent of the daily recommended intake of the 10 essential amino acids for adult nutrition3.2. Carbohydrate and Fiber: Quinoa contains 10 percent total dietary fiber4. Dietary fiber is essential for digestive health, and can promote satiety, reduce cholesterol absorption, and reduce risk and severity of gastrointestinal infection and inflammation5. Its soluble fiber content also serves as a prebiotic6. 3. Lipids: Quinoa seed oil contains polyunsaturated fatty acids (PUFAs) with a higher omega-6 to omega-3 ratio than other plant oils7. Other essential fatty acids in quinoa contribute to brain development, insulin sensitivity, cardiovascular health, immunity, inflammation and membrane function8. These fatty acids may exert beneficial physiological effects as well9. 4. Vitamins: Quinoa is rich in Vitamins A, B, C, and E. These vitamins play a major role in metabolism, regulating cell growth and development, and improving vision10. 5. Minerals: Quinoa contains sufficient amounts of calcium, copper, iron, magnesium, phosphorus, potassium and zinc. Its mineral content is higher than that of rice, wheat and other cereals11. 6. Saponins: Saponins, found in the outer seed coat of quinoa, are useful in producing organic crops because they protect crops from microbial infection and from being eaten by insects and birds. 7. Phytoecdysteroids: Found in quinoa, phytoecdysteroids can help build muscle and reduce stress12. Other benefits include promoting growth, healing wounds and serving as an antioxidant and antidepressive13. 8. Phenolics: Phenolics are compounds found in quinoa that serve as antioxidants and have anti-inflammatory, anticancer, antidiabetic, anti-obesity and cardioprotective effects14.9. Betalains: Betalains are what give quinoa their yellow, red and black colors15. They contain a range of health-promoting properties and serve as a natural dye for foods. Betalains are approved by the U.S. FDA and EU as a safe, natural alternative to synthetic color ingredients in foods. 10. Glycine betaine: Glycine betaine is an amino acid in quinoa that has been involved in the treatment and prevention of diabetes, obesity and cardiovascular disease16.
