Frequently asked
FAQ
Is nutritional yeast the same as baking yeast?
No. Nutritional yeast undergoes a heating process that deactivates (kills) it, so it cannot be used to make bread rise.
Why do vegans love nutritional yeast?
Besides its delicious cheese-like flavor, it is often fortified with B-vitamins, including B12, which is an essential nutrient that is difficult to get on a vegan diet.
