Nutritional yeast is not the same as brewers yeast, they are from differing strains of yeast. Nutritional yeast is deactivated yeast and is a great source of nutrition, it is a complete protein and is particularly rich in the B vitamins. That is great news for vegetarians and vegans alike. It is naturally low in fat and also in sodium. Because of this it is a popular condiment for those wanting to limit the salt intake but wanting a little more taste on food. It can be used by everyone to add a cheese like flavour to cooking or as a condiment. Great to use instead of parmesan cheese. Go on try it.
Dried inactive yeast.
