We are frequently asked about this grain that is promoted as high in protein. It is high in protein for a grain but 50g quinoa contains 1 block of protein and almost 4 blocks of carbohydrate so it should really be treated as a carbohydrate rather than protein.
The other limitation of grains as protein is that because they are high in fibre you don’t tend to absorb a lot of the protein from them. The only vegetable that is truly high is protein is soy.
Quinoa is low glycaemic so small amounts could be used to supplement lots of favourable vegetables in a meal.
