What is Nutritional Yeast?

What is Nutritional yeast? Here’s your comprehensive guide to the health benefits and how to use it in your everyday meals.

What is Nutritional Yeast?

Nutritional yeast is a savoury substitute used to add a cheesy flavour to dairy-free dishes. Nutritional yeast is a species of yeast known as “Saccharomyces cerevisiae”. While brewer’s and baker’s yeasts are technically made from the same species of yeast, it is essential to note that nutritional yeast is a very different product.

Nutritional yeast is grown specifically to be used as a food. To produce it cells are grown for several days on a sugar-rich medium like molasses. The yeast is then deactivated with heat, harvested, washed and dried. Crushed into a powder or into flakes and is ready to be added to our food. The yeast cells are killed during manufacturing so nutritional yeast is not alive, it’s a fermented, deactivated yeast that doesn’t grow.

It is used in cooking to give a cheesy, nutty flavour to dairy-free recipes and is a popular food product used in vegan cooking to add protein and additional vitamins and minerals to one’s diet.

Is it Nutritious?

Studies have shown that due to its nutritional content, yeast in this form has a wide range of potential health benefits, from increasing a person’s energy, supporting their immune system, to protecting the body from free radical damage.

  • It is naturally low in kilojoules and sodium. It’s free from sugar, gluten, grains (wheat, corn, rice), soy, eggs, starch, colours or preservatives.
  • Nutritional yeast is a complete protein as it contains all 9 essential amino acids that our bodies can only get from food.
  • It is rich in B vitamins (especially rich in thiamine, riboflavin, niacin, B6 and B12).
  • It contains minerals such as zinc, selenium and manganese.

What are the Health Benefits of Nutritional Yeast?

It may boost your immunity and reduce inflammation – Nutritional yeast contains 2 main carbohydrates, alpha-mannan and beta-glucan.

Studies have shown that they stop pathogenic bacteria from attaching to the lining of the intestines. They stimulate immune cells, making them more effective at fighting infection and they attach to certain types of toxins that yeast can produce in food crops and reduce their harmful effects.

Energy booster – Nutritional yeast is fortified with vitamin B12. This vitamin may help boost energy levels, as a deficiency of B12 can lead to fatigue and weakness.

Contains powerful antioxidants – Nutritional yeast contains the powerful antioxidants glutathione and selenomethionine. They protect our cells from damage caused by free radicals and heavy metals and also help our bodies eliminate toxins from the environment.

Promotes healthy skin, hair and nails – Recent research has suggested that nutritional yeast can combat brittle nails and hair loss, and may improve some common skin problems like acne.

How Do I Use Nutritional Yeast?

As mentioned above nutritional yeast has a savoury, cheesy or nutty flavour. It comes either in the form of flakes, granules or powder. Use it as a savoury seasoning to flavour dishes or sprinkle over salads to add protein and extra nutrients. Further suggestions but there is no end to the uses:

  • Add to dairy-free nut cheese spreads.
  • Add to white cauliflower or nut milk sauces to use in place of a dairy white sauce.
  • Mix into hot savoury dishes to add flavour.
  • Use to thicken gravies, sauces and stews.
  • Stir into creamy type soups for added nutrients and flavour.
  • Add to stuffing mixtures.
  • I add nutritional yeast flakes to my casserole or mornay grain-free toppings.
  • Add to an almond meal or coconut mixture when crumbing chicken or fish.
