Hydrogen Water Is Not “the New Nutrient;” Health Claims Are Hype, Not Science.

A new fad, drinking hydrogen water, claims to provide all kinds of health benefits. The scientific evidence isn’t there. Hydrogen is an element, not a medicine Hydrogen water? Good grief! There are already two atoms of hydrogen in every molecule of water (H2O). They are not talking about that; they mean molecular hydrogen, the gas

There’s No Vaccine for HIV/AIDS, But There’s Truvada

Science has made great strides in understanding, treating, and preventing HIV/AIDS. We can hope for an AIDS vaccine, but meanwhile there is a pill that can markedly reduce the risk of becoming infected. Truvada: a good alternative while we wait for an AIDS vaccine.

Skin pH: Salesmanship, Not Science

People are being encouraged to worry about the pH of their skin and to try to change it. These concerns and interventions are not supported by scientific evidence. You have probably heard of the alkaline diet. Public knowledge of pH, the scale by which acids and bases are measured, is plagued by misinformation. People who

The Best Science from The New England Journal of Medicine

The editor-in-chief of The New England Journal of Medicine has selected a dozen articles published during his tenure that epitomize the best of science-based medicine. This is the Science-Based Medicine blog, but all too often we talk about things that are not science-based medicine. Examining what is not science-based medicine is a good way to better understand what science-based

Critical Thinking in Medicine

Rodin’s Thinker is doing his best to think but if he hasn’t learned critical thinking skills, he is likely to make mistakes. The human brain is prone to a multitude of cognitive errors. Critical thinking in medicine is what the Science-Based Medicine (SBM) blog is all about. Jonathan Howard has written a superb book, Cognitive Errors

Should Evidence-Based Medicine Be Replaced By Interpersonal Medicine?

An opinion piece in the New England Journal of Medicine complains about the limitations of evidence-based medicine (EBM) and recommends a new approach they call “interpersonal medicine.” In my opinion, good clinical medicine is already interpersonal medicine; there is no need for something new. The 22 November 2018 issue of The New England Journal of Medicine carried an opinion

The Future of Medicine

April 17, 2012 Eric Topol, MD, has written a book about the convergence of the digital revolution and medicine. It is full of fascinating information and prognostication, but I wish he had given it a better title.  He called it The Creative Destruction of Medicine: How the Digital Revolution Will Create Better Health Care. Medicine

Colonoscopy: More Misinformation from Mercola

Joseph Mercola, D.O., runs the website mercola.com which is full of misinformation, advocates all kinds of questionable alternative treatments including homeopathy, and discourages vaccination and other aspects of conventional medicine. Like Dr. Oz and Andrew Weil, he is more dangerous than easily recognizable quacks in that he combines some good medical information with egregious misinformation, and readers who

Coca’s Pulse Testing to Diagnose “Allergies”

I recently got an email from a gentleman who told me I was wrong about many things because I “come from an era of incomplete medical education and information.” He rambled on but had two main points: modern doctors fail to recognize a kind of allergy that defies standard diagnosis and that is the cause

Mainstream Doctors Actually Do What CAM Claims They Don’t

Alternative medicine proponents criticize mainstream medicine and think they can do better. Evidence from medical journals shows that their criticisms are not valid. Advocates of complementary and alternative medicine (CAM), including naturopaths and functional medicine practitioners, constantly criticize mainstream medicine. The recurrent themes are: Doctors don’t do prevention They only prescribe drugs and surgery and
