The first episode I'm listening to, anti-fluoride.
Added to water to cover for places that didn't want to take it out.
No evidence that it prevents cavities
More toxic than lead
Mostly comes from China so its contaminated with arsenic
Coming up, why vaccinations is bad.
Edit, so its just a short clip from a recent episode but I looked up the guest and the first link is that he's being investigated for treating a child with a hyperbaric chamber, the diseases he was treating appear to exist only in his imagination. I didn't hear the full interview but it appears the guy thinks lyme disease is caused by vaccinations. I don't know if he means lyme disease or chronic lyme disease.
