The famous food item nutritional yeast, often known as “nooch,” finds frequent use in vegan cookery. Its name comes from the variety of vitamins, minerals, and antioxidants that it has, including protein. According to studies, it has a number of possible health advantages. These include decreased cholesterol and defense against cellular deterioration that causes disease. This article defines nutritional yeast, examines its health advantages, and offers unique applications for it. Saccharomyces cerevisiae, also referred to as “nooch,” is the species used to make itt, which is also used to make bread and beer (1). But because it is an inactivated variety, using it to produce bread or beer wouldn’t turn out well and would probably be too bitter to be enjoyable.
Compared to other forms
Yeast derived from S. cerevisiae often falls into one of three categories:
- Baking yeast. This leavens bread and cooking kills it, but it still leaves a yeasty, earthy flavor.
- Used in beer. Beer is made with brewer’s yeast. You can eat the leftover cells after brewing too. They tase bitter, but are quite nutritious.
- Dietary yeast. This type is grown specifically for human consumption. It is inactive as the cells die during production. It provides a savory or umami flavor and people often us it in cooking or as a spice.
Nutritious yeast varieties
The production of nutritional yeast is a meticulous process. It begins with the cultivation of Cerevisiae cells over an extended period, typically several days. These cells grow on a diet rich in medium-high type sugars. Molasses is a key component in providing the necessary nutrients for their robust growth and development. This initial stage sets the foundation for the yeast to thrive and multiply, ensuring a nutrient-rich final product. Subsequently, it undergoes a crucial heat treatment process to deactivate it, rendering it suitable for further processing. The following stages involve the careful harvesting of the yeast, followed by meticulous cleaning to ensure purity. Finally is the drying, crushing and packaging..
Varieties
Nutritional yeast, a versatile and nutrient-dense product, comes in two distinct varieties. Unfortified and fortified, offering consumers choices based on their individual dietary preferences and health goals. The unfortified variety does not contain additional vitamins or minerals beyond the naturally occuring ones. This purity ensures that consumers receive only the nutrients produced through the yeast’s natural biological processes, providing a wholesome and unaltered source of vitamins and minerals.
In contrast, the fortified variety undergoes an intentional enhancement process during manufacturing. To augment the nutritional content, manufacturers also put additional vitamins in the final products, providing an extra boost of essential nutrients. Transparency is paramount, and the ingredient list on the packaging explicitly discloses the inclusion of these supplementary vitamins. This fortified version caters to consumers seeking an additional source of specific vitamins and minerals in a convenient and easily accessible form.
The most popular variety and one with the most advantages is fortified nutritional yeast. You can find it for sale as powder, granules, or tiny flakes. You can often find it in the bulk bins of health food stores or in the spice or condiment department of the majority of supermarkets. It has a light-yellow color, and packaging options include plastic containers, shakers, and bags. Almost every eating plan or style can use this item. It is naturally low in sodium and calories, free of fat, sugar, gluten, and animal products.

To reap the greatest health advantages, purchase fortified varieties, especially if you’re using nooch to supplement your diet with additional vitamins and minerals. You might not care as much if nutritional yeast is fortified if you’re using it only for the flavor.
Nutritional yeast is abundant in vitamin B12
Getting adequate vitamin B12 is one of the main nutritional problems for people who adopt a vegan diet, which forbids the use of any animal products. Your blood and nerve cells depend on this vitamin to remain healthy. Additionally, it aids in DNA synthesis and the prevention of megaloblastic anemia, a blood disorder that causes weakness and exhaustion. Supplements are the most constant and dependable source of vitamin B12 when following a vegan diet. However, consuming this vitamin-fortified foods like nutritional yeast may also be beneficial. Notably, 2 teaspoons of it provide an incredible 313% of the daily value (DV) for vitamin B12.
Possesses strong antioxidants
Integrating antioxidants into your diet can be beneficial in lowering the risk of diseases by neutralizing unstable molecules known as free radicals. Nutritional yeast, in particular, contains robust antioxidants like glutathione and selenomethionine (9, 10). These antioxidants play a crucial role in protecting your cells from oxidative stress induced by free radicals and heavy metals, and they may contribute to the body’s elimination of environmental pollutants. The presence of these potent antioxidants in nutritional yeast highlights its potential as a dietary source for combating oxidative damage and supporting overall health. As oxidative stress is implicated in various health issues, incorporating it into your diet could be a strategy to enhance your body’s defense mechanisms against environmental challenges and promote well-being.
May improve immunological function
Nutritional yeast contains two main carbohydrates, alpha mannan and beta glucan, which might play a role in safeguarding the body against infections, as indicated by studies involving animals. These carbohydrates possess antibacterial and antifungal properties. Specifically, beta glucan is believed to boost immunity and overall health by activating immune cells and targeting the gut flora. Although findings from animal studies are promising, research involving humans is currently insufficient.
There is a need for more studies with human participants to better understand how alpha mannan and beta glucan in nutritional yeast might impact our immune system and overall well-being. As it becomes more popular for its nutritional content, it’s crucial to further investigate and confirm these potential health benefits to make informed decisions about incorporating it into our diets. Exploring how these components affect human health is essential for a better understanding of their role in supporting our immune systems and promoting overall wellness.
May also reduce cholesterol levels
Nutritional yeast’s beta glucan is noted for its potential in reducing cholesterol levels. Specifically, men with elevated cholesterol who consumed 15 grams of beta glucan daily for eight weeks experienced a 6% reduction in total cholesterol. It’s worth mentioning that beta glucan is not exclusive to nutritional yeast; oats and barley are two other foods containing this compound. Various studies have shown the significant cholesterol-lowering effects of oat beta glucan. It is particularly important given the correlation between high cholesterol levels and an increse in the risk of heart disease. While there are slight differences in the chemical structures of beta glucan in oats and yeast, previous research suggests that they share similar cholesterol-lowering effects. This underscores the potential health benefits associated with the consumption of beta glucan-rich foods like nutritional yeast and oats, providing individuals with natural means to manage their cholesterol levels.
