Is Nutritional Yeast okay for me to Eat?

Nutritional yeast is produced from a single-celled organism, Saccharomyces Cerevisiae, which is grown on molasses and then harvested, washed, and dried with heat to deactivate it. Because it’s inactive, it doesn’t froth or grow like baking yeast does so it has no leavening ability.


Nutritional yeast can be found in the bulk aisle of most natural food stores and is sold in the form of flakes or as a yellow powder. It has a strong flavour that is described as nutty, cheesy, or creamy, which makes it great for use as a cheese substitute.

It is often used as an ingredient in recipes or as a condiment, and is popular among vegans and vegetarians as it is a good source of B-complex vitamins, and contains trace amounts of other vitamins and minerals as well.

Nutritional Yeast



As already noted, nutritional yeast is a significant source of B-complex vitamins, and is also a source of selenium, zinc and protein.

It has a low fat content, is gluten-free (this may vary depending upon the brand), and contains no added sugars or preservatives.

Sometimes nutritional yeast is fortified with B12, which renders it an excellent addition to the vegan diet as B12 is absent from plant foods unless it is added in supplemental form.






It is important to differentiate between good and bad yeasts, as there is a great deal of confusion surrounding this topic. Candida albicans is a prime example of a harmful yeast. It can be found growing and causing inflammation in our bloodstream and organs, and thrives on the abundant sugar found in the modern diet. It robs the host of essential nutrients and keeps the blood very acidic.

Wild, airborne yeast found in naturally fermented kombucha and sourdough breads can be detrimental when consumed by someone with a pathogenic candida infection.digestion

Nutritional yeast is the extracted content from deactivated species that cannot be used for leavening or fermenting, and definitely cannot infect you.

Yeast extracts do not contain any Candida species, which are the most common cause of pathogenic yeast infections in humans. Nutritional yeast is also gluten-free, however if you are allergic or sensitive to yeast products, for example beer, you should take caution.

Allergic reactions to yeast and Candida yeast infections produce very different symptoms. To read about the “bad guy” yeasts click here. Or click here to learn some good tips for the difference between bloating and belly fat.


If you are new to nutritional yeast, listed below are some ways to begin incorporating it into your diet:-

  • Sprinkle it on popcorn.
  • Add a little to the cooking water for polenta.
  • Sprinkle on vegetables to add flavour.
  • Make “almond parmesan” by blending nutritional yeast with raw almonds in a food processor.
  • Add a tablespoon or two to bean dishes to enhance flavour.

Evidently, nutritional yeast can be a great addition to your diet, whether you are vegetarian, vegan or a meat-eater!

Her understanding of the value and significance of having a balance within all aspects of health and hormones developed rapidly, and she began studying Naturopathy. During the years at university Bree experienced a dramatic journey, growing and changing into an health professional with a passion for her career in the health industry and Endocrinology.
