Since Quinoia is 60% starch, it is very illegal.

From http://www.hort.purdue.edu/newcrop/proceedings1993/V2-222.html#TAXONOMY:

The nutritional value of quinoa has been known for a long time to be superior to traditional cereals and is, in fact, superior to milk solids in feeding trails (White et al. 1955). Protein content ranges from 10 to 18% with a fat content of 4.1 to 8.8%. Starch, ash, and crude fiber average 60.1, 4.2, and 3.4%, respectively (DeBruin 1964; Ballon pers. commun.). The ash has been found to primarily consist of potassium and phosphorus (65% of total). Calcium and iron are significantly higher in quinoa than in rice, maize, wheat, or oats (White et al. 1955; DeBruin 1964). Variations have been observed between species and between landraces within species. Many landraces of quinoa contain saponin in the seedcoat. Saponins function as "antinutrients" and are frequently associated with plant lipids. They are not normally absorbed from the gut and have been shown to induce small intestinal damage or reduce intestinal absorption of nutrients (Jenkins 1988). Quinoa saponin is a known hemolytic when mixed with blood cells. In South America, saponin removed from quinoa is used as a detergent for clothing, washing and as an antiseptic to promote healing of skin injuries (D. Cusack pers. commun.; E. Ballon pers. commun.). Saponin can be removed either mechanically or with a water rinse (White et al. 1955; DeBruin 1964; Mahoney et al. 1975). Mechanical abrasion systems currently in use fail to remove all saponin, leaving bran with saponin attached to perisperm granules (Becker and Hanners 1991).
