Quick Summary

Vegans primarily use nutritional yeast for its cheesy flavor and essential nutrients like B12, while yeast extract adds savory umami taste to dishes. Baker's yeast is also used for leavening baked goods.

Key Points

Nutritional Yeast (Nooch): The most common yeast for vegans, prized for its cheesy, nutty flavor and use as a dairy-free cheese substitute.
Key Nutrients in Nutritional Yeast: It is a rich source of complete protein, fiber, and B vitamins, with many brands fortified with vitamin B12.
Yeast Extract for Umami: This provides an intense savory, umami flavor used in sauces, stocks, and meat analogues to deepen flavor.
Baker's Yeast for Baking: This active form of yeast is used to make bread and other doughs rise and is vegan-friendly.
Yeast is a Fungus: As a member of the fungi kingdom, yeast is not an animal, making it perfectly suitable for a vegan diet.
Fortification is Key for B12: Since yeast does not naturally produce B12, vegans should choose a fortified nutritional yeast brand to ensure they get this essential vitamin.

The Vegan-Friendly World of Yeast

Yeast is a single-celled fungus that is suitable for a vegan diet because it does not involve animal products. Vegans commonly consume nutritional yeast, yeast extract, and baker's yeast, each offering unique uses in plant-based meals.
