Vegan’s treat nutritional yeast like it’s the dehydrated cheese in a mac and cheese box. It’s not, but it does make great, creamy, cheese-like sauces. For a long, long time (think 30 of my 31 years), I stayed far away from it. 27 of those years were spent in ignorance that this food existed, two of those years were spent avoiding it because it was odd, one was spent avoiding it because I have read of contraindications between inflammatory bowel disease and nutritional yeast. Then I gave in, tried it, loved it, and now know just what it is.
