Benefits of Nutritional Yeast

 

benefits of yeast

Nutritional yeast has lots of health benefits, including boosting

energy, protecting against cell damage, lowering cholesterol,

and more.

A type of inactive yeast, nutritional yeast is popular in vegan

and vegetarian cooking because it's a rich source of vitamin

B12, a nutrient that’s typically only available in animal products

like milk and eggs. Likewise, one of the most surprising health

benefits of nutritional yeast is that it is also a high-protein food.


1. Nutritional Yeast Boosts Energy.

Nutritional yeast is typically an incredibly rich source of B12, a

vitamin that’s essential for energy, red blood cell creation, and

metabolism. When your B12 levels are low, you may experience

greater fatigue. When they’re sufficient, you may have more

natural energy and tire less easily.

Many nutritional yeast brands add synthetic vitamins to their

yeast during production. These fortified nutritional yeast

products often have more than a day’s worth of nutrients like

B12. Indeed, one tablespoon of some nutritional yeast can serve

up more than six times your daily value of B12.

Nutritional yeast is also one of the only plant sources of vitamin

B12. This vitamin is typically only found in animal foods like

milk, fish, and eggs. In one study, vegans who supplemented

their daily diet with one tablespoon of nutritional yeast were

able to restore their B12 levels if they had previously been

deficient.


2. Nutritional Yeast Is Good for Your Skin, Nails, and

Hair.

One nutritional yeast benefit may be seen instead of only felt.

Nutritional yeast, research suggests, may help combat hair, skin,

and nail problems, such as thin, weak nails and acne.

The 2015 study looked at various types of nutritional yeast, with

different groups of synthetic supplements, and found that many

could prevent skin problems, hair loss, thinning hair, brittle

nails, and more. Skin benefits are prominent in adolescents

while nail and hair benefits are possibly stronger in mature

women.


3. Nutritional Yeast May Help Lower Your Cholesterol.

Nutritional yeast contains two predominant types of

carbohydrates: alpha-mannan and beta-

glucan. Research suggests beta-glucan can lower cholesterol.

In one study, men who consumed 15 grams of nutritional yeast

(that’s about 1½ tablespoons) every day saw their total

cholesterol level fall by six percent. In a 2009 animal study,

mice that fed on beta-glucan from yeast had significantly lower

cholesterol levels after just more than a week of eating the food.


4. Nutritional Yeast May Protect Against Cancer.

Every day, your cells are under attack from free radicals,

molecules that can damage and ultimately destroy the healthy

cells in your body. Certain antioxidants can bind with free


radicals when they enter your body and destroy them.

Nutritional yeast is a rich source of antioxidants.

Selenium is one such antioxidant, and nutritional yeast is a rich

source of this nutrient. One study suggests that poor selenium

levels may increase a person’s risk for cancer, in particular men.

However, eating selenium-rich plant foods, such as nutritional

yeast and whole grains, may help combat free radicals and

prevent the development of cancer cells.


5. Nutritional Yeast Strengthens Your Immune System.

Nutritional yeast is made from the yeast strain Saccharomyces

cerevisiae. Research suggests this yeast strain may be able to

support your immune system, reduce inflammation, and help

ward off intestinal ailments.

Indeed, one study found that nutritional yeast has a probiotic-

like effect on the intestines. It may help prevent some

gastrointestinal infections like E. coli and Salmonella. More

research in humans is needed to verify these protective effects

and to better understand how nutritional yeast stimulates

immune cells.
