Delicious
(NaturalNews) Brewer's yeast is a highly nutritious byproduct of the beer-making process. It is obtained during the process of formation from the grain, hop and malt extracts, and absorbs the vitamins and nutrients contained in them throughout the process. Unlike nutritional yeast and baker's yeast, brewer's yeast has a bitter (though not unpleasant) taste due to its active chromium content.

Brewer's yeast is a deactivated yeast, meaning that the yeast itself is dead, but the nutrients it contains remain intact. It has been used as a safe and much-loved nutrient supplement for centuries in Europe.

Health benefits

High in protein - Arguably, brewer's yeast's biggest attraction is its impressive concentration of protein. One ounce (28 grams) of it contains approximately 14.9 grams of protein, which is a whopping 30 percent of an adult's recommended daily intake (RDI). This makes the yeast a superb protein source for vegetarians and vegans. Protein is needed for a large number of reasons, including the growth and repair of cells and muscles, transportation of compounds and protection from infections.

Lowers glucose and cholesterol - According to a study published in the May 2011 edition of the Journal of Trace Elements in Medicine and Biology, the chromium found in brewer's yeast can reduce glucose and cholesterol levels. Researchers found that diabetic patients who consumed chromium-rich brewer's yeast over a three-month period demonstrated drastically reduced levels of glucose, total cholesterol, and 'bad' LDL cholesterol. Debittered yeast (which is stripped of many nutrients, including chromium) did not contain the same benefits.

Good source of beneficial bacteria - Brewer's yeast is a probiotic, and eating it helps line the colon with beneficial bacterial cultures. This improves digestive health and gives it laxative qualities, making it a good cure for constipation. Moreover, brewer's yeast contains no fat and is rich in fiber (around six grams per ounce), making it an excellent weight loss food.

B-vitamin complex - Brewer's yeast contains unusually high amounts of B-vitamins. One 28 gram serving, for instance, contains 75 percent of our RDI of thiamine (which boosts the immune system and improves our ability to withstand stressful conditions), 84 percent of our RDI of riboflavin (which activates antioxidant enzymes and helps metabolize fats), 47 percent of our RDI of niacin (which helps the body produce sex and stress-related hormones in the adrenal glands), 40 percent of our RDI of vitamin B6 (which synthesizes and breaks down amino acids), 15 percent of our RDI of folate (needed for DNA and RNA synthesis) and 5 percent of our RDI of vitamin B12 and pantothenic acid, which aid cellular metabolism.

Rich in trace minerals - Brewer's yeast contains essential trace minerals such as iron, magnesium, potassium, and zinc. One cup of it also contains 1 milligram of copper, which is 50 percent of our RDI, and 63 micrograms of selenium, which is 90 percent of our RDI. Copper helps to regulate cholesterol, hormones and cellular energy levels, while selenium is an important antioxidant that provides anti-aging benefits and guards us from degenerative diseases like cystic fibrosis and cancer.

Brewer's yeast and nutritional yeast

Although many people assume that brewer's yeast is the same product as nutritional yeast, they are different. Nutritional yeast is a yeast grown on sugar beets or wood pulp, while brewer's yeast is grown on beer-making ingredients. Ultimately, though, both contain similar nutritional profiles, and you can't go wrong with either of them.

Brewer's yeast can be bought in supplement form online, or in certain natural health stores.
