My opinion is that it's a sales pitch. The doctor that is being interviewed is a employee of the website. He is involved in the development and sales of products sold on the sight . Notice how half way through the video he starts with how their product can help with the problem. Concerning his stats , he presents no real study data .The information he dose show is from the FDA concerning the harmful effects of these products while stating that the FDA can't be trusted. Yes I agree that the ingredients he mentions can be harmful,but he gives no information on acceptable or toxic levels of these chemicals. Dr Group is just a pitch man in a not so clever infomercial made to look like a news article.
