A discussion on what environmental toxins are and how they affect our bodies. We discuss how low doses of toxins can be harmful. Toxins can create different responses in high doses compared to low doses. Toxic susceptibility is highly individual. We discuss liver function, nutrition status, diet, genetics, epigenetics, gut health, and methylation and how each are affected by a toxic load. We discuss how to decrease your toxic exposure by paying attention to cosmetics, cleaning products, pesticides, antibiotics, food additives, BPA, drinking water and air.
