What is Nutritional Yeast Anyway?

After my son’s dairy and egg allergy diagnosis, my household was thrown into living a dairy-free and egg-free life. I must admit that we were completely unprepared and clueless for at least a year. It was a steep learning curve, but I’ve discovered so many amazing vegan products along the way and learned how to prepare meals so that my household does not miss dairy or eggs at all.

One of the products that is new to me is Nutritional Yeast. I add it to sauces, soups, popcorn and pretty much anything that I want to give a distinct “cheesy” flavour to. I use it to replace parmesan cheese in my pastas and salads, and it puts the finishing touch on my Vegan Mac and Cheese sauce. Nutritional yeast adds an amazing cheesy and earthy flavour to almost anything, and ever since I discovered it, I’ve gotten hooked!

But what is Nutritional Yeast anyway? And why haven’t I heard of it before?

Nutritional Yeast is a deactivated yeast made from Saccharomyces Cerevisiae, a single-celled organism which is grown on molasses and then harvested, washed, and dried with heat to “deactivate” it. It doesn’t froth or grow like active yeast used in baking, so it can’t be used for leavening.

Nutritional Yeast can be found in most health food stores or bulk stores, and looks like yellow flakes or powder. It’s commonly referred to as “hippie dust” or “nooch.” In Australia, it is sometimes sold as “savoury yeast flakes” and in New Zealand, it is called Brufax.

Nutritional Yeast is full of vitamins and nutrients, particularly B-vitamins, folic acid, selenium, zinc, and protein, and is often fortfied with vitamin B12 so that it can be used as a supplement for people eating a plant-based protein diet. This is likely why I haven’t heard of it in my past life, because my guess is that it’s mainly marketed to vegans and vegetarians, especially when fortified with B12.

As a meat eater, I don’t really need additional B12 supplements, which is why I was thrilled to find Non-fortified Nutritional Yeast Flakes by Sari Foods. This nutritional yeast product is 100% whole food based and naturally occurring with no unnecessary additives. The Sari Foods nutritional yeast is an excellent source of vegan protein and fiber and contains all 18 amino acids and minerals such as iron, selenium and zinc, as well as a natural vitamin B-complex. Most important to my household, is the fact that this Nutritional Yeast product is not manufactured with gluten, wheat, soy, milk, nuts, eggs or shellfish.
