Is Nutritional Yeast Gluten-Free?

Nutritional yeast is naturally gluten-free. It is made from deactivated yeast, which is a fungus, not a gluten-containing grain. Nutritional yeast is generally safe to eat for someone with celiac disease or another gluten-related disorder.

If you are highly sensitive to gluten, it is important to note that even if a product is typically considered gluten-free, you should always check product labels and look for allergen statements.

While nutritional yeast is usually gluten-free, a manufacturer may declare wheat as an allergen if the product happens to be processed in a facility where wheat is present. This can only be determined by examining the specific product packaging.

Ingredients in Nutritional Yeast

Nutritional yeast is essentially inactive dry yeast that is often fortified with vitamins during the growing process. For example, take a look at the ingredients listed in Bragg Nutritional Yeast:

Dried Yeast, Niacin, Pyridoxine Hydrochloride (Vitamin B6), Thiamin Hydrochloride (Vitamin B1), Riboflavin (Vitamin B2), Folic Acid (Vitamin B9), Cyanocobalamin (Vitamin B12)

What Is Nutritional Yeast?

Nutritional yeast is a deactivated form of the yeast, Saccharomyces cerevisiae, which is the same species of yeast that makes baker’s or brewer’s yeast. Nutritional Yeast is most often used as a dietary supplement due to its many nutritional benefits or in plant-based and vegan cooking, because it is useful for adding an umami or savory flavor to a variety of dishes.

The small yellow flakes often come in a shaker container and have a distinct earthy smell. The product can be used as a healthy seasoning for popcorn, a vegan substitute to make “cheesy” sauces and dips, or for adding nutty flavor to salads, roasted vegetables, and more.

Affectionately dubbed “nooch” as a shortened form of the word nutrition, nutritional yeast gets its name from the nutritional benefits it provides, including protein, fiber, essential vitamins, minerals, and antioxidants.

Is Nutritional Yeast Healthy?

According to WebMD, the benefits of nutritional yeast are many. It is a nutrient dense food that is a great source of high-quality protein, vitamins, minerals, and antioxidants. It contains all nine essential amino acids, making it a complete protein, which is helpful for those on a plant-based diet.

Just 2 Tablespoons of nutritional yeast contains 8 grams of protein, 4 grams of fiber, and is a good source of B vitamins, potassium, and zinc. Fortified nutritional yeast is also a good source of vitamin B12 and folate.

The fiber in nutritional yeast is beta-glucan, which may help reduce cholesterol levels and strengthen your immune system.

How is Nutritional Yeast Made?

To produce nutritional yeast, S. cerevisiae yeast cells are grown in a carbohydrate rich solution, typically molasses from sugarcane or sugar beets. This yeast substance is then enriched with vitamins. Finally, the yeast is dried with heat, rolled into flakes, and then packaged for use.

This drying process not only pasteurizes the product, but also deactivates the yeast, which means nutritional yeast cannot be used for making bread or beer.

Still Confused About Yeast and Gluten?

If you've been gluten-free for a bit, you may have heard or think that yeast is not gluten-free. While it is true that not all yeast is gluten-free, most of it is. The terms used to define each type of yeast can lead to some confusion, so let's quickly break it down here.

Most yeast is gluten-free. This includes:

Nutritional Yeast
Baker's yeast
Active dry yeast
Instant yeast: Except for one specific product, Red Star Platinum Yeast, which contains wheat.

The types of yeast that may not be gluten-free are:

Brewer's yeast
Spent brewer's yeast
Yeast extract
Autolyzed yeast extract

Brewer's yeast and spent brewer's yeast are not gluten-free unless specified on the product label. This is because these types of yeast are a byproduct of the beer brewing process, which means it likely contains gluten from the barley used to make beer.

Autolyzed yeast extract and yeast extract may also contain gluten from barley and should be avoided unless the product is labeled gluten-free.
