Brewer's Yeast Powder 18 oz: K

Brewer's yeast, which is often called nutritional yeast, was originally a by-product of the brewing of beer. Brewer's yeast is nutritionally the same as Nutritional yeast, but, as a by-product of beer-brewing, it has a characteristic bitter hops flavor. Nutritional yeast, the same yeast, is grown on mineral enriched molasses and grain instead of hops, and more often used as a food supplement, because it tastes better. This is actually debittered Brewer's Yeast, in other words, Nutritional Yeast. At the end of the Nutritional yeast growth period, the culture is pasteurized to kill the yeast. This retains the nutrients, but deactivates the live yeast (i.e. baking yeast) as a food supplement because the live yeast continues to grow in the intestine and actually uses up the vitamin B in the body instead of replenishing the supply. Yeast are single-celled microorganisms that reproduce by budding. They are biologically classified as fungi and are responsible for converting fermentable sugars into alcohol and other byproducts. There are literally hundreds of varieties and strains of yeast. In the past, there were two types of beer yeast: ale yeast (the 'top-fermenting' type, Saccharomyces cerevisiae) and lager yeast (the 'bottom-fermenting' type, Saccharomyces uvarum). Today, as a result of recent reclassification of Saccharomyces species, both ale and lager yeast strains are considered to be members of S. cerevisiae. Nutritional and Brewer's yeast contains high levels of many important nutrients, including all of the B vitamins (except for B12), 16 out of 20 amino acids, and 14 different minerals. The amino acids (proteins) in yeast help the body repair tissue and fight disease. Nutritional and Brewer's yeast has a very high protein content, with one tbsp providing 4.6 g, making it a rich source of protein for vegetarians. It is also high in phosphorus. Because yeast is such a rich source of B vitamins, it enhances the roles these vitamins play in the body. The B-complex vitamins help your body metabolize carbohydrates, fats, and proteins. They also support the nervous system and help maintain the muscles used for digestion. Brewer's yeast is also an important source of chromium. The U.S. FDA recommends 120 mcg of chromium daily, but 90% of Americans are deficient in this important mineral. Chromium has the ability to significantly lower blood cholesterol levels.
