What is Nutritional Yeast?

Nutritional yeast is a species of yeast identified as Saccharomyces cerevisiae. It is the same type of yeast used to brew beer and bake bread. The difference between the baker and the brewer's yeast is the cells in nutritional yeast are killed during manufacturing and are not alive in the final product. It is used in cooking as it adds a nutty, cheesy, and savory flavor to the dish. Nutritional yeast is also a great source of protein, vitamin B, and minerals required for optimal health.
