Nutritional Yeast Vs Yeast

Nutritional yeast is a deactivated form of yeast, specifically Saccharomyces cerevisiae, that is often used as a dietary supplement and flavor enhancer. It is rich in vitamins, especially B-complex vitamins, and is a popular source of protein and antioxidants. Nutritional yeast has a cheesy, nutty flavor and is commonly used by vegans and vegetarians to add flavor to dishes like popcorn, pasta, and sauces, while also providing essential nutrients that may be lacking in their diets.

Yeast, in a broader sense, refers to a diverse group of unicellular fungi that are used in various fermentation processes, most notably in baking and brewing. The most common type of yeast used in these applications is Saccharomyces cerevisiae, which ferments sugars to produce carbon dioxide and alcohol. In the context of nutrition, yeast is a vital ingredient in bread-making, contributing to the leavening process, and it also plays a crucial role in the production of alcoholic beverages and certain dairy products. Yeast is also a source of protein and various vitamins, particularly B vitamins, though its primary role in food is as a fermenting agent.
