Brewer's yeast comes from the saccharomyces cerevisiae fungus. It is ground into a powder and used in a variety of foods. Unlike the yeast you use in baking, brewer's yeast is an inactive yeast that has no leavening power. It is easy to digest and is a rich source of B vitamins, essential amino acids and minerals. It is also a vegetarian source of vitamin B12.
Foods Containing Brewer's Yeast
Only a few food products contain brewer's yeast, including Vegemite and Marmite, which are food spreads made from brewer's yeast. Typically, you spread them on crackers and toast. It is more common to find brewer's yeast in its powdered form.
Uses for Brewer's Yeast
You can use the powdered form of brewer's yeast sprinkled over hot and cold cereals. You can add it to a sauce or soup or add it to a morning smoothie. When you first introduce brewer's yeast to your diet, start with 1/4 teaspoon and double that amount every other day until your daily intake is between 1 to 3 tablespoons.
