How Much Do You Know About Nutritional Yeast?

When you think of yeast you may think of bread or beer. Nutritional yeast is different because it is an inactivated version of the yeast that is used in baking or brewing. Nutritional yeast is a vegan protein source that contains important nutrients such as amino acids, minerals, and B vitamins.1 It is often used to add flavor to foods, but it is primarily used to support health on a variety of levels.

The Health Benefits of Nutritional Yeast

Protein is vital to health as it is a key structural and functional component of every cell in the body and is especially important for the development of various metabolic processes.2 And yet, research shows that eating plant proteins may help better support overall health more so than animal proteins.3

Because nutritional yeast is such a potent protein source, it is often used by vegans and vegetarians; however, other people can benefit from it including athletes, the elderly, and even children.1

Research shows that nutritional yeast may help support immune and gut health.4 Beta-glucans are fibers found in nutritional yeast that have been shown to support heart health and normal cholesterol levels.5

How to Use Nutritional Yeast

Nutritional yeast comes in delicate flakes that can be easily sprinkled on foods like popcorn, pasta, salads, stews, soups, and casseroles. It can also be added to juices and smoothies. The typical daily amount is 1.5 rounded tablespoons. Nutritional yeast can last a long time if it is stored in a cool, dark place, and sealed tightly to keep the moisture out.

When shopping for a nutritional yeast product, look for a high-quality brand with yeast primarily grown from molasses to provide that delicious nutty flavor with no bitter aftertaste. Even though nutritional yeast contains many key nutrients, you may want to consider choosing fortified nutritional yeast that contains a full spectrum of naturally occurring amino acids and vitamin B12 for extra health support. Vitamin B12 is important because it helps support cellular energy and nervous system health, as well as healthy red blood cell production.6
