But lots of people seem to want to believe that drug companies are doing evil things. Dr. Sidney Wolfe of Public Citizen, the Ralph Nader-founded group, has long complained that drug companies push bad drugs. You might think, therefore, that he'd say Trudeau is on to something, but he doesn't.
Have people like Wolfe set Trudeau and others like him up for success by convincing people that there's collusion between drug companies and the government?
"I think it's possible to be critical about the drug industry, and yet say they do some very clear good for which there's clear evidence," Wolfe said.
Despite Trudeau's fantastic book sales, Wolfe, author of "Worst Pills, Best Pills," said Trudeau's book isn't worth much. "I would say 10 percent of that is common sense and 90 percent is quacker," he said.
Of course, many illnesses go away on their own or are psychosomatic. And I suspect that's why many of Trudeau's customers say they were helped. But the Internet is filled with complaints too. Many of them sad.
One woman said she stopped using her drugs based on Trudeau's advice, and suffered a terrible seizure. A man said his tumor grew larger after he relied on Trudeau's book.
Veronica Krammes says she has had spinal surgery and suffers constant pain. She and others complained about Trudeau's book on the infomercialscams.com Web site. "I bought the book because I wanted to see natural cures that he promises to give me and there's none in here. It's to me, a total waste of money. It was a scam," she said.
Joyce Ball's sister is dying of cancer and is too ill to appear on TV. Joyce bought her Trudeau's book.
She said her sister felt cheated. "She felt betrayed, and she felt she was a fool for believing what he had to say," she said.
I wanted to ask Trudeau about all this, but he wouldn't sit down for a taped interview. A few months ago, however, he did talk to "Nightline's" Jake Tapper (Click Related link above to read Tapper's interview.)
But he proved very adept at spinning the truth in the "Nightline" interview.
In the interview, he emphasized that his $2 million settlement was not a fine, but consumer redress.
And his infomercials have more misinformation. He claimed that the government and pharmaceutical industry spend virtually no money on researching natural remedies.
But that's a lie. Last year the National Institutes of Health spent millions studying natural remedies. Trudeau claimed longevity specialist Dr. Andrew Weil concurs with many of his points.
But Weil's publicist told us that's not accurate.
Trudeau says Nobel Prize winner Dr. Richard Axel proved that prescription drugs are harmful and asks why that's not front page news.
It's not front page news because Axel says his research had nothing to do with that!
Trudeau also claims the American Medical Association published a report that said 900,000 people died last year by taking nonprescription and prescription drugs.
And the AMA said, that's a lie.
Tapper caught Trudeau lying about the source of his natural cure for diabetes.
Trudeau said, "The University of Calgary has 25 years of research. And I'm really glad you brought it up because diabetes can be, if not completely cured and wiped out in America, dramatically reduced by this herbal combination."
Tapper and "Nightline" called the University of Calgary to verify Trudeau's claim.
