Nutritional yeast is actually microscopic fungi. After harvest, the nutritional yeast is washed, drained, dehydrated and pasteurized, then packaged in powder or flakes.
Nutritional yeast is cultivated for its nutritional value. It contains very little fat or sodium, and it is free from sugar, gluten, lactose, soy, additives or GMOs. Nutritional yeast is rich in thiamine, riboflavin, niacin, folic acid, vitamin B6 and vitamin B12. These nutrients are essential: they help release the energy contained in food and keep cells healthy.
Thus, nutritional yeast is an interesting product in raw and vegan diets, because it is above all a plant source of proteins and vitamins. The taste is a bit like that of cheddar or even nuts. It even contains the famous umami flavor, which induces satiety. Nutritional yeast can be used as a condiment or as an ingredient in sauces, broth or stir-fry.
