Cold And Flu Symptom Relief
Not one, but two double-blinded and placebo-controlled studies have been published to date which suggest that nutritional yeast may help with cold and flu side effects.
In the first 12-week trial of 116 people, it was reported :
EpiCor, a modified yeast based dietary supplement taken daily, appears to significantly reduce the incidence and duration of cold and flu-like symptoms when compared to placebo in subjects vaccinated for seasonal influenza
In that study, everyone had received the flu vaccine. Similar positive results were seen in a concurrent trial of the same size involving non-vaccinated participants.
Why is this happening?
It might be because nutritional yeast has been found to stimulate B lymphocytes and natural killer cells in the body. Two things that reduce inflammation and support immune system performance. This is similar to how elderberry extract appears to work.
What Does It Taste Like
Nutritional yeast is yellow in color and most commonly comes in flakes but you may see it granules or powder as well. It has a nutty, cheesy, salty, umami flavor and is often used to add a cheesy flavor to dairy-free dishes. You may see it labeled as savory yeast, nutritional seasoning or nutritional yeast flakes. These are all the same thing.
What Is Nutritional Yeast Made Out Of
Yeast is a single-celled fungus which feeds on sugar . Nutritional yeast refers to varieties specifically grown for human consumption. Usually its made from a strain of Saccharomyces cerevisiae.
Unlike bakers yeast and brewers yeast which are both living, nutritional yeast has been deactivated . Its main health benefit is being a rich source of B vitamins and minerals, and hence, its name.
Since nutritional yeast is not living, it cant cause or worsen yeast infections such as Candida albicans overgrowth. Even though some sources allege that danger, there isnt science to support it. At least if one is talking about standard nutritional yeast, which only consists of dead fungi.
Whats nooch? Its another name for nutritional yeast. The most common nickname. Its particularly popular among vegans and those who eat it regularly. This is probably the most popular brand.

Is Nutritional Yeast A Complete Protein
I think its safe to say that nutritional yeast is a complete protein, or extremely close to it.
Even though it falls a tiny bit short on methionine, thats not really a fair comparison. The 16 mg/g from WHO is for methionine plus cysteine. The data for cysteine wasnt available for nutritional yeast in the study, but its a safe bet that its over 2.
Regardless, heres a list of the best plant-based methionine food sources if youre interested.
In addition to being well balanced, it has a significant amount of protein as well.
In one quarter cup of nutritional yeast, theres:
- 60 calories
- 8 grams of protein
- 0.5 grams of fat
- 5 grams carbohydrates
Over half the calories come from protein. Its no surprise that nutritional yeast is included in many vegan high protein recipes.
Additionally, there are a ton of B vitamins, which people on a plant-based diet sometimes lack .
Nutritional Yeast May Boost Immunity
Nutritional yeast contains two main carbohydrates alpha-mannan and beta-glucan.
Studies show that adding alpha-mannan and beta-glucan to animal feed can reduce the frequency of infections from pathogenic bacteria like E. coli and Salmonella in pigs, as well as reduce tumor formation in mice .
Beta-glucan and alpha-mannan help protect against infection in several ways :
- They stop pathogenic bacteria from attaching to the lining of the intestines.
- They stimulate immune cells, making them more effective at fighting infection.
- They attach to certain types of toxins that yeast can produce in food crops and reduce their harmful effects.
While animal studies are promising, further research is needed to determine whether alpha-mannan and beta-glucan have these effects in humans.
Summary Nutritional yeast contains the carbohydrates alpha-mannan and beta-glucan, which animal studies suggest may boost immunity.

Why Does Your Nutritional Yeast Taste Very Different Than Other Nutritional Yeasts On The Market
Sari Foods Non-fortified Nutritional Yeast does taste different to other available nutritional yeast productsit has a much cleaner and fresher taste due to its lack of synthetic additives. Sometimes it can take a while for our taste buds to adjust to the flavor of pure and natural whole foods when they’ve been used to the taste of artificial nutrients. In these situations, we often suggest reducing the dose right down to a light pinch or sprinkle on food before building it back up again to allow taste buds time to adjust.
Use It As A Seasoning
I frequently use nutritional yeast as a seasoning, sprinkling it over just about anything, but its also awesome added to recipes likes soups and sauces in place of cheese.

How Nutritional Yeast Is Made
This vegan condiment is made by culturing a yeast in a growing medium for several days. The growth medium requires a high amount of glucose and can vary from corn, sugarcane, beet molasses, etc . When the yeast is ready, it is killed off with heat, removed, and dried.
If an ethical vegan is concerned about environmental effects, nutritional yeast proves to have some concern. The highest amounts of acetaldehyde, a hazardous air pollutant, are released from the manufacturing of nutritional yeast. In 2017, the Environmental Protection Agency proposed restrictions on the manufacturing process of nutritional yeast though only on the nooch manufactured for human consumption. The nutritional yeast produced for the feed of animals is not regulated in the same way. Regardless, the environmental impact of the manufacturing of processed foods is and should continue to be part of the conversation of veganism.
Potential Health Benefits Of Nutritional Yeast
Nutritional yeast is a great source of vitamins and minerals. It also contains all nine essential amino acids, making it a complete protein like those found in animal products.
Complete proteins are important nutrients that assist functions like tissue repair and nutrient absorption. They may also prevent muscle loss.
Other potential health benefits of nutritional yeast include:
The fiber in nutritional yeast, beta-glucan, may reduce cholesterol levels. Nutritional yeast is also a low-glycemic food that contains chromium, a mineral that may help regulate your blood sugar. Maintaining good blood sugar and cholesterol levels lowers your risk for diabetes and heart disease.
Immune System Support
Beta-glucan is also believed to strengthen your immune system. One study found that people who consumed nutritional yeast were 25% less likely to catch a cold than those who didnât. Those who did get sick experienced less severe symptoms and sleeping problems.
Nutritional yeast also contains high amounts of antioxidants, which may have anticancer properties and improve certain immune responses.
Nutritional yeast may improve your physical recovery after exercising. Studies have found that athletes who consumed yeast products with beta-glucan experienced less post-workout fatigue and better moods than those who didnât.

It May Help Lower Cholesterol Levels
The beta-glucan found in nutritional yeast may also lower cholesterol.
In one study, men with high cholesterol who consumed 15 grams of beta-glucan derived from yeast daily for eight weeks lowered their total cholesterol levels by 6% .
Another study found that mice fed beta-glucan from yeast had significantly lower cholesterol levels after only 10 days (
Although the chemical structure of beta-glucan in oats is slightly different than the structure of beta-glucan in yeast, data suggests that they have similar cholesterol-lowering effects .
However, no study to date has investigated whether consuming nutritional yeast in its whole form has the same effects. Further research is needed.
Summary The beta-glucan in nutritional yeast may help lower cholesterol levels.
Are You At Risk
Truth in Labeling is a website dedicated to exposing the dangers associated with MSG. They list the neurological symptoms I experienced among the common symptoms of MSG. They also record 70 adverse reactions caused by MSG, including cardiac, gastrointestinal and respiratory issues.
While MSG does not cause noticeable symptoms in everyone, it is a known carcinogen and damages the brain. More controversial is whether or not nutritional yeast contains MSG. My body’s reaction to nutritional yeast suggests it does. I don’t react negatively to other glutamate-rich foods, like bone broth and aged cheeses .
ome people react to the food ingredient monosodium glutamate. What many dont know, is that more than 40 different ingredients contain the chemical in monosodium glutamate that causes these reactions. Jack Samuels, creator of the Truth in Labeling Campaign
Jack Samuels, the late foremost authority on MSG in the traditional community, includes yeast food, yeast nutrient in his list of ingredients that always contain processed free glutamic acid.
Logically speaking, when we look at how MSG develops in foods, the production method of nutritional yeast matches. It is a manufactured, fermented food, highly concentrated in flavor and glutamates. This kind of man-made food is exactly where we see MSG occurring, as a byproduct of other food processes . Also, interestingly, the manufacture of MSG itself is very similar to the process of creating nutritional yeast !
