Many chronic disorders come from digestive problems and inadequate nutrient absorption. Even with a very complete and balanced diet, nutrients have to be properly digested and absorbed to transport vitamins to different parts of the body. Proper gastrointestinal functioning also ensures elimination of toxic molecules, microbes and undigested food particles from the body to prevent infections, toxic reactions, allergies, and other health problems.
Dysbiosis is the overgrowth of yeast and/or bacteria in the gastrointestinal tract. The negative role of abnormal intestinal microorganisms in gastrointestinal disorders is widely known. However, research also shows the relationship between the gastrointestinal and other systems in the body, such as the neurological, hepatic, and immune systems. For example, excessive yeast in the gut produces toxic metabolites, which can pass through the blood-brain barrier and alter neurological functioning causing "brain fog," behavior problems, and learning difficulties. Toxic bacteria byproducts (like those from Clostridia) can interfere with neurotransmitters and cause a variety of problems including chronicfatigue and mental health disorders.
