Although vegans and vegetarians admire nutritional yeast for its nutrition, almost anyone would appreciate it for its savory taste, and nutty and cheesy flavor. It is often used to imitate cheese in certain vegan dishes, while also thickening sauces and dressings.
Since yeast cannot produce vitamin B12, nutritional yeast is likely fortified with it when the vitamin is listed on a nutrition label. Thatâs alright though, as the combination of B vitamins and other nutrients make it a fantastic superfood that is gluten-free. It is an excellent way to boost immunity, improve digestion, promote healthy hair and skin, prevent birth defects, and more.
Read on to discover why nutritional yeast may be the perfect addition to your next meal.
How Is Nutritional Yeast Made?
Want to know how nutritional yeast is made? The production is actually a five-step process.
The production of nutritional yeast begins with a pure parent yeast culture of Saccharomyces cerevisiae. The yeast seed will grow in a sterile environment, and later it is transferred to a container for cultivation.
In cultivation, the control of temperature and pH of the yeast are important to create optimal growth. The good conditions allow the yeast to obtain a purified medium of air and nutrients.
After the growing process, fermented yeast liquid is passed through a process that will concentrate yeast cells. The result is an off-white liquid known as nutritional yeast cream.
Pasteurization of the cream is a process that makes the yeast inactive. This is where fortification occurs, and nutrients like vitamin B12 are added to help enhance the nutritional profile of nutritional yeast.
Finally, the yeast is dried and sized into powder, flakes, or granules in a similar way as cornmeal.
Facts and History of Nutritional Yeast
Studies conducted by Louis Pasteur led to a better understanding of yeast as a living organism. Beginning in the 20th century, this led to the commercial production of nutritional yeast.
Nutritional yeast, along with blackstrap molasses, wheat germ oil and wheat germ, and yogurt, were once part of the four cornerstones of the health food movement. They were known as reliable superfoods since they were primary sources of minerals and B vitamins. Nutritional yeast is considered to have the ability to biotransform nutrients at an accelerated rate where the body can readily use the nutrients.
It is important to differentiate between nutritional yeast and brewerâs yeast. Nutritional yeast is far superior to brewerâs yeast and contains a higher amount of B vitamins than wheat germ and other natural foods.
Nutritional yeast is used around the world, and it is given various other names due to its unappetizing name. It is called nooch and yeshiâan Ethiopian name that means âfor a thousand.â New Zealanders call it âbrufax,â while in Australia, it is called âsavory yeast flakes.â
Nutritional yeast also contains important food factors like SOD (superoxide dismutase), glutathione, RNA/DNA, beta-glucans, amino acids, lipoic acid, trace minerals, polysaccharides, GABA (gamma-aminobutyric acid), B-complex vitamins, and more than 40 proteolytic enzymes.
Nutritional Yeast Nutrition Facts
What are nutritional yeast nutrition facts? It is considered to be a good source of vitamins for vegans and vegetarians that often fail to get enough B vitamins in their diet. It is important to note that B vitamins are only found in the fortified form of nutritional yeast.

Two tablespoons of fortified nutritional yeast also contains 8 grams of protein and 4 grams of fiber. Fortified nutritional yeast contains a massive amount of vitamins B1, B2, B3, B6, and B12, folate, as well as some vitamin B5, zinc, iron, manganese, copper, and magnesium.

The following is a comprehensive nutrition chart with information for two tablespoons of fortified nutritional yeast or 16 grams of the food.
|Total Fat||0.5 g||1.00%|

5 Health Benefits of Nutritional Yeast
What are the health benefits of nutritional yeast? For starters, it is a complete protein source and contains nine of the 18 amino acids that the body cannot produce. It is especially useful for vegans or vegetarians that struggle to get enough protein in the diet.
Protein deficiency can lead to difficulty building muscle mass, a sluggish metabolism, fatigue and low energy levels, poor concentration, slow wound healing, low immunity, moodiness, and blood sugar changes, as well as muscle, joint, and bone pain. Nutritional yeast also enhances immunity, benefits digestion, promotes healthy hair and skin, aids in a healthy pregnancy, prevents birth defects, and provides antibacterial and antiviral properties.
The following are five detailed health benefits of nutritional yeast to help understand more about this inactive yeast product.
1. Enhances Immunity
Nutritional yeast contains the compounds trehalose, beta-1,3-D-glucan, glutathione, and mannanâall linked to improved cholesterol, reduced risk of cancer, and enhanced immunity. The many vitamins and minerals in it also help prevent nutrient deficiencies and help with wound healing and tissue repair. Beta-1,3-D-glucan is also considered a type of fiber that may benefit immunity and reduce cholesterol.
2. Contains Antiviral and Antibacterial Properties
Nutritional yeast is considered the fourth most-prescribed herbal mono-preparation in Germany due to its antibacterial and antiviral properties. It is only behind Ginkgo biloba, St. Johnâs wort, and horse chestnut.
Since nutritional yeast does not have an association with Candida albicans, this inactive yeast is actually beneficial for chronic candida symptoms. It is also beneficial against Salmonella, Staphylococcus, and E. coli (Escherichia coli) infections.
3. Benefits Digestion
German monographs show that nutritional yeast is a good medicinal choice for loss of appetite and diarrhea. The probiotics in it also benefit diarrhea patients. It is also a good choice for people with lactose intolerance since it can be used to replace cheese or dairy in certain dishes.
A study published in the Oxford Journal suggests that Saccharomyces cerevisiae expresses isomaltase and sucrase activity but no lactase activity. As a result, it may improve malabsorption in patients with a sucrase-isomaltase deficiency that unintentionally or intentionally consumes sucrose.
4. Promotes Healthy Hair, Nails, and Skin
Nutritional yeast is an exceptional source of B vitamins, which benefits skin, hair, and nails. Vitamin B5 and biotin, in particular, are great for healthy skin, hair, and nails, and they also decrease signs of aging like skin spots and redness. The vitamin B3 it contains can also treat chronic acne and benefit the skin overall.
5. Helps with Healthy Pregnancy and Prevents Birth Defects
Nutritional yeast is a great choice for pregnant women since it is high in folate. Getting enough folate during pregnancy may help prevent birth defects like spina bifida.
It is good to consume more natural foods with folate like nutritional yeast since it is not possible to consume too much folate from food. However, getting too much folate in supplement form may mask a vitamin B12 deficiency.
How to Use Nutritional Yeast
As mentioned, you can find nutritional yeast is in the bulk or supplement sections of a health food store. ItÂ is perfect for people that are lactose intolerant. You can add it to smoothies or sprinkle it on pasta, soups, salads, popcorn, garbanzo beans, and mashed or baked potatoes. Some people compare nutritional yeast to Parmesan cheese in its flaked form.
