Yeast are, basically, the ecologist and the undertaker of life. Yeast are enzyme factories that break down any organic molecule on earth into the elements of carbon, hydrogen, nitrogen, oxygen, and minerals. Without yeast, we on earth would be shoulder deep in dead plants and animals that never go away. Humans have harnessed the enzyme-making ability of yeast to create a dazzling array of enzymes for industry and human consumption. We use yeast to make bread, ferment grapes into wine, and much more.
Yeast can create territorial poisons to mark their turf, called antibiotics.
Americans consume 40 million pounds per year of these mycotoxins, both directly in prescription drugs for bacterial infections and indirectly through animals that grow faster when constantly fed antibiotics. Yeast are at their best while degrading a field of autumn leaves or living in harmony with trillions of other microorganisms in our gut. Yeast are at their worst when they invade the lining of the gut and penetrate into the bloodstream to cause havoc throughout the body, such as Candidiasis. Clearly, this is a serious problem in America, affecting men and women, young and old alike. Yeast infections can be superficial, such as vulvovaginitis, ring worm, dandruff, jock itch, toenail fungus, psoriasis, rash, sinusitis, asthma, etc.
