                                According to the USDA, a standard 7-gram packet of active dry baker's yeast contains approximately 21 to 23 calories, an amount that is virtually insignificant to your overall dish. This tiny count is often a surprise to bakers and home cooks wondering about the caloric contribution of a single packet of yeast.
