Again I'm not a native english speaker, "toxins" is just a generic world I used to try to convey "anything the body can't process right now, how that is destroy it".
"Some molecules are things that have nothing to do in the body (Maillard reaction output, antibiotic in the meat, pesticide in fruits, etc). Some are just regular things we can process but in a greater concentration that is healthy. Some are just natural waste of our regular body processes, but in a greater quantity than we can manage in our current health."
