Naturopathic Kitchen: Nutritional Yeast

What is Nutritional Yeast?

Nutritional yeast is a deactivated version of the yeast Saccharomyces cerevisiae. 1 The activated form is used to bake bread and brew beer, but the deactivated version–nutritional yeast–is less bitter and has a pleasant, savory flavor that is often used to mimic the taste of cheese in vegan recipes. It comes in flakes, powder, or granules, and may be sold in shakers, bags, or in the bulk section of your local health-food store.

Nutritional yeast is available in both fortified and unfortified varieties. Unfortified nutritional yeast does not contain any added nutrients, while the fortified version has added vitamins. Fortified nutritional yeast is the most common variety and, for the purposes of this article, is what we are referring to when we talk about nutritional yeast.

The Health Benefits of Nutritional Yeast

May Help Manage Cholesterol

The beta glucan content in nutritional yeast may help lower cholesterol. 2 Beta glucans are polysaccharides that interact with lipids and biliary salts in the bowel to reduce cholesterol levels. 3 One study found that men with high cholesterol who consumed 15 grams of yeast-derived beta glucan every day for eight weeks saw a 6% decrease in cholesterol levels. 4 If you are looking for natural ways to reduce your cholesterol, adding more nutritional yeast to your diet may be beneficial for you.

High in Vitamin B12

An adequate intake of vitamin B12 is crucial because it plays an essential role in DNA synthesis, nerve and blood-cell health, and the prevention of anemia. 5 Nutritional yeast is very high in vitamin B12–just two teaspoons gives you 313% of the daily recommended intake. 6 People following a plant-based diet often struggle to get enough vitamin B12, so nutritional yeast is highly recommended for those who do not consume animal products. 7

Packed with Antioxidants

Nutritional yeast is a good source of antioxidants. Antioxidants are compounds that help protect your body against harmful free radicals. 8 A diet rich in high-antioxidant foods may help reduce your risk of developing a number of serious conditions, including cancer, macular degeneration, and cardiovascular disease. 9 Nutritional yeast contains selenomethionine and glutathione, both of which are powerful antioxidants. 10
