Why Nutritional Yeast shows up in protein-forward diets
Prized in vegan cooking mostly for its cheese-like umami flavor from glutamic acid, but a 2 tbsp serving genuinely carries about 8g of complete protein as a side benefit.
Serving-size math
A 2 tbsp (16g) portion delivers 8.0g of protein and roughly 52 calories. Scaled per 100 calories, that works out to 15.38g of protein — useful for comparing against other foods on a calorie-matched basis rather than a weight-matched one.
Prep tip
Sprinkle on popcorn or roasted vegetables while still warm — the flakes stick better to a slightly oily, warm surface.
