Why Quinoa (cooked) shows up in protein-forward diets

Botanically a seed, not a true grain, and one of the very few in this whole 'grain' category with a complete amino acid profile — most grains (rice, wheat, oats) are low in lysine the way beans are low in methionine.

Serving-size math

A 1 cup (185g) portion delivers 8.1g of protein and roughly 222 calories. Scaled per 100 calories, that works out to 3.67g of protein — useful for comparing against other foods on a calorie-matched basis rather than a weight-matched one.

Prep tip

Rinse thoroughly before cooking — quinoa's natural coating (saponin) tastes soapy and bitter if skipped.
