Our “guts” contain bacteria, good and bad, which affect the body in a variety of ways. According to research conducted by the Univ. of McMaster, evidence shows our behaviors can be influenced by our intestinal health.
Medically, several types of gastrointestinal diagnoses also include symptoms of anxiety and apprehension. Depressions can also be influenced by the “gut” being off balance. It is possible for the intestine to hold more bad bacteria than good, which may affect other diseases including autism as well as other mental illnesses.
