Metabolic Type: Unscientific Premise, Dangerous Advice
Dr. Joseph Mercola is a prolific writer with a large following. Much of his advice is well-founded and worth reading.
Lately, however, I have been asked by readers of DiseaseProof to assess some of his more outlandish claims: for instance, that coconut oil has miraculous properties, that "metabolic type" (as determined by a $59 online survey) determines dietary requirements, that special butter and grass-fed beef are wonderful health foods.
By looking at these things in detail, I have found that in some cases Dr. Mercola is not practicing good science.
That does not mean everything he advocates is wrong or that his diet is not better than the much worse diet that most Americans eat. However his judgment and nutritional advice is not scientifically based and demonstrates poor judgment and bias.
For instance, there has never been a study showing that any blood type or "metabolic type" is protected from the dangerous effects (primarily heart disease and cancer) of a diet rich in red meat and butter. His advice appeals to the majority of Americans who are addicted to meat and want to justify their dangerously high consumption of saturated fat (butter, cheese and meat) with rationalizations that lack adequate scientific support. Prudent people must recognize that red meat and butter (even if consumed raw from grass-fed cows) must be avoided or consumed in very minimal quantities by all types of people to assure protection against premature aging and the leading causes of death.
I have already addressed his claims about coconut oil, in the comments of a previous post.
Over the next few days, we will investigate:
