With only 1,500 species identified, yeast – a single-celled microorganism – makes up just 1% of the fungi kingdom. It can be found in many ecosystems, including vegetation, soil, the aquatic (rivers, oceans, lakes, creeks, ponds), and, surprisingly to some, the bodies of both humans and animals.
Most are aware that yeast can be either beneficial or harmful to the health of its host. Beneficial yeasts, such as Brewer’s, Baker’s, and Torula, are often referred to as Nutritional Yeasts. Due to the presence of various vitamins, minerals, Beta Glucan polysaccharides, and Beta 1 3 Glucans, these beneficial yeasts generally enhance the functioning of the immune system, as well as aid in normalizing blood sugar levels. Harmful yeasts, however, such as candida, are pathogenic. This means that they cause disease.
