Claims that “toxins” cause autism are part of a general trend of blaming ill-defined “toxins” for an array of health effects along with promises that detoxes cure those ailments. Read more in this article at Science-Based Medicine, Toxins: The New Evil Humours.
The first important thing to get out of the way is that people talking about toxins everywhere aren’t even using the word properly. “Toxicants” is a general term for any toxic substance. “Toxin” is a term for the subset of toxicants that are produced naturally by plants and animals. Improper use of the correct vocabulary is a sign that claims should be approached with skepticism.
The second important point is that the very idea of detoxing is based on a number of faulty premises not backed by science or evidence. Most importantly that there is no credible evidence that “detoxes” actually remove these supposed toxicants.
