nutritional yeast

noun

plural nutritional yeasts

: a deactivated yeast (such as Saccharomyces cerevisiae) used in powdered or flake form as a flavoring or condiment

Nutritional yeast is not a byproduct; it's grown specifically for dietary supplement use and has a better taste and nutritional profile than brewer's yeast (some brands are good sources of B-12). Its pleasant nutty-cheesy flavor makes it appealing to vegetarians—as a topping for popcorn, for example.

—Andrew Weil
