Caveman nutrition or paleo diet is getting more and more popular. People who are on paleo diet have different opinion about quinoa however it's still regarded as a healthy option.
According to John Willimas Ph.D. - he has a degree in archeology and anthropology and very interetsted in nutrition - is a healthy food choice when you are on paleo diet.
He says:
Another food of the grain variety that I think many people would benefit from is quinoa (pronounced "KEEN-oowa"). It's a South American grain domesticated by the predecessors of the Incas that grows on a plant that looks a lot like spinach. So it's a "leafy grain" rather than a grass grain such as wheat and corn.
Quinoa is gluten-free, and contains none of the allergens common to grains from the grass family such as wheat, rye, barley, oats, and corn. Furthermore, quinoa contains lysine, an amino acid deficient in many grains, making it a complete protein. Quinoa is also an excellent source of calcium, magnesium, iron, phosphorus, and B vitamins. It's one of the good guys in the grain family, so pick some up next time your in a whole foods-type market.
