Mercola endorses a long list of products and positions that stand well outside mainstream science. A news release on his website claims that physicians are the third leading cause of death in America and that traditional medicine is “responsible for killing and injuring millions of Americans every year…” He opposes immunization, fluoridation and mammography; claims that amalgam fillings are toxic; and advises against eating many foods that the scientific community regards as healthful, such as bananas, oranges, red potatoes, white potatoes, all milk products, and almost all grains [17]. He urges his followers to avoid “dangerous electro-magnetic fields,” specifically noting electric razors, all watches with batteries, automatic car door openers, alarm clocks and microwaved foods, because “natural medicine states that the introduction into the human body of molecules and energies, to which it is not accustomed, is more likely to cause harm than good ….” His alternative cures include prescribing “organic, non-commercially harvested” seaweed supplements to treat thyroid problems.
My mom basically because she chose Mercola quackery and used garlic supplents instead od taking her prescribed blood thinners. End up with clots in her lungs and started the slide downhill from there.
She died at 79 a few months after her mother passed at 101.
Assuming the source you cite is not the Big Pharma equivalent of the subsidized "fact checkers" used by the MSM to criticize conservatives, their criticism does not prove mainstream science right. If their facts are correct and not distortions, it shows Mercola to be wrong.
