That was my question coming out of the article: why exactly do we want quinoa? The native Americans stopped growing it because it didn't yield well enough. Modern farmers have had trouble growing it here in the US. And I've never found the taste astounding, so I find myself wondering why we don't stick to rice, soy, lentils, beans, corn, and wheat?
My original text:
"The arid, cool land that quinoa needs was plentiful, since little else could grow there. And thus far, that trait has made it difficult to grow elsewhere." (posted link)
"Protein content is very high for a cereal/pseudo-cereal (14% by mass), yet not as high as most beans and legumes." ( http://en.wikipedia.org/wiki/Quinoa )
I'm puzzled. Why not stick to beans, which are cheap and plentiful, and come in a wide variety of shapes and colors?
