My bag of Simply7™ Quinoa chips is based on quinoa flour and contains a significant amount of added starch. It claims to have 9 grams of protein/12 grams of carbs, a 3:4 ratio.
However, pure Quinoa has only 8 g protein per 34 grams non-fiber carbs, see: http://nutritiondata.self.com/facts/cereal-grains-and-pasta/10352/2 This is a less than a 1:4 ratio. There are no other ingredients that add a significant amount of protein. Does it really have that much protein?
