Yeast is a vegan-friendly food. Neither animal nor plant, yeast is a microscopic member of the fungus family, and its most common culinary strain is
Saccharomyces cerevisiae.
In addition to its deep umami flavor, yeast provides a vegan-friendly source of amino acids, proteins, bioavailable minerals, as well as B12 and folic acid (B9).
These essential nutrients can be challenging to obtain through an entirely plant-based diet.
Technically speaking, yes—yeast is a living unicellular organism. In the same way that humans eat carbs and exhale CO2, yeast “eats” sugar and produces gas. Humans harness the power of yeast’s metabolism to rise bread and ferment alcohol. Yeast’s ability to metabolize in this way confirms its status as a “living” organism.
Unlike members of the animal kingdom, though, yeast has just one cell and contains no nervous system. Yeast does not feel pain in the way multi-cellular animals with nervous systems can. Consequently, mainstream vegans do not see the harvesting or consuming of yeast as animal slavery, exploitation, or cruelty. However, some
very strict vegans may avoid yeast because it is alive in a fundamental biological sense.
Yes, the majority of vegans consider yeast to be a vegan-friendly food. Unlike animals, yeast has just one cell and contains no nervous system; therefore, it is not cruel to consume.
In that respect, some vegans do not consume Beer and Wine.
