The thing that really bothers me about Weinstein's approach is that, while he and his wife are scientists, they're exceedingly quick to assert their hunches as scientific fact. They wear their scientist labels on their sleeves but their thinking is far more ideological. In a recent podcast about fluoridation in tap water, they were talking about how they avoid iodized salt, because iodine is a reactive chemical and you don't want to OD on it. Ludicrous. You'd sooner die from the sheer quantity of salt you'd have to ingest before the iodine even starts to become a problem.
