Understanding how our probiotics work and how they help prevent disease is critical to our ability to stay healthy. This book condenses and simplifies the science gathered from over 600 research studies to communicate precisely what probiotics are, how they boost our immunity and the many diseases they help prevent. Probiotics Simplified also describes each major probiotic species and its accumulated research over the past fifty years. Here we will learn how to chose and supplement probiotics, how to consume the right prebiotics and even recipes for making some of the many traditional probiotic foods. Note: this simplified version has been drawn largely from the author's previous work, "Probiotics-Protection Against Infection" and thus contains some content duplications.
