Quinoa is naturally gluten-free and contains iron, B-vitamins, magnesium, phosphorus, potassium, calcium, vitamin E and fiber. It is one of only a few plant foods that are considered a complete protein and comprised of all pernine essential amino acids. Quinoa also has a high protein to carbohydrate ratio when compared to other grain products. It was proposed by NASA to be an ideal food for long duration space flights.
Quinoa also contains a healthy dose of fatty acids.
"About 25% of quinoa's fatty acids come in the form of oleic acid, a heart-healthy monounsaturated fat, and about 8% comes in the form of alpha-linolenic acid (ALA), the omega-3 fatty acid most commonly found in plants."
