About Yeast
Yeast, a single-celled fungus, is widely used in baking, brewing, and fermenting across a variety of global cuisines. Nutritionally, yeast—particularly nutritional yeast—is a protein-rich food source with 40.4 g of protein and 26.9 g of fiber per 100 g. It is also a good source of B vitamins, including B12 in fortified varieties, and minerals like iron and potassium. Brewer’s yeast and nutritional yeast, though inactive forms, are distinct from active yeast used in baking. Its origins trace back to ancient Egypt and Mesopotamia, where it was utilized for bread and beer production, and it remains fundamental to culinary traditions worldwide.
