BENEFITS: Even in small amounts, nutritional yeast is a significant source of some B–complex vitamins. Some brands are fortified with additional B12. It has approximately 9 grams of protein in 2 tablespoons. It provides 9 amino acids that the human body cannot produce and 5% (unfortified) to 20% (fortified with B12) of recommended daily iron.
USES: It can be used as a flavor enhancer in cheese substitutes, mashed or fried potatoes, scrambled tofu, and popcorn.
WARNINGS: In large amounts, the high fiber content may cause digestive discomfort, and high niacin content can cause facial flushing. Some brands may contain tyramine, which can trigger migraines in some individuals.
