Award-winning cosmetic dentist and best-selling author, Dr. Kourosh Maddahi, reveals the results of over three decades of research into our bodies’ first line of defense; the Microbiome. In The Toxic Overload, the reader is taken through dozens of studies and breakthrough scientific research that debunks the Hygiene Hypothesis and the concept of killing our complex network of good bacteria with the daily use of antibacterial and antimicrobial products, linking them to widespread rises in autoimmune disease and allergies. With a 30 day guide to a strengthened Microbiome and overall healthier body, Dr. Maddahi has laid open a completely new path to hygiene and whole-body wellness.
