Why do you like yeast ?
I love nutritional yeast because it adds great flavour as well as nutrition to foods. I have been using nutritional yeast in my diet regularly for the past 15 years. I love its nutty and “cheese-like” flavour. As a nutritionist, and as a vegan vegetarian myself, there are great culinary applications to using nutritional yeast in many recipes.

Nutritional Yeast is an excellent source of thiamine, riboflavin, niacin, folic acid, vitamin B6 and vitamin B12. These nutrients are essential to help release energy from foods and build healthy cells. Many of the B vitaimins are also essential of a healthy nervous system.
Is yeast an adequate supplement to a vegan diet ?
Nutritional yeast is an excellent food and nutritional supplement for people on a vegan diet. It is particularly rich in Vitamin B12 which is often lacking in vegan diets. I am a vegan myself, and I use it regularly as a seasoning I add to salads, vegetables, pasta dishes and other entrees. I also love to sprinkle it on my air popped popcorn. I also used in as a seasoning ingredient in many of the recipes I make and have included it as an ingredient in recipes I demonstrate in cooking classes and in recipes I develop for books.
