Just a few years ago, I was a practicing naturopathic doctor. I considered myself to be a primary care physician who had been trained in the best of two worlds: supposedly, one was modern medicine and the other was a mixture of alternative practices based in “ancient wisdom.”

The risk of people developing Type 2 diabetes is lower for people who consume more whole grains, fruits, vegetables, nuts, and legumes, notes a study in PLOS Medicine.


British taxpayers spend billions for the health care of an increasingly overweight population. The World Health Organisation predicts that almost three-quarters of men and two-thirds of women in the UK will be overweight or obese by 2030.

Graham MacGregor is Professor of Cardiovascular Medicine at the Wolfson Institute of Preventive Medicine, Queen Mary, University of London was trained as a nephrologist but then became interested in blood pressure control mechanisms, particularly related to the renin-angiotensin system, the mechanisms whereby salt puts up blood pressure. Now he says he knows a magic bullet for halting obesity: unsurprisingly it is in line with all of the latest fad claims in media.
A core platform of the massive promotion of e-cigarettes has been the argument that because these products involve no combustion but only vaporization, they must be substantially less dangerous than smoked tobacco. Few – including me – would disagree with that.

Acupuncture, like most other alternative therapies, is particular popular for indications that are:

1. chronic

2. associated with a high burden of suffering,

3. not easily treatable with conventional therapies,

4. are frequently resolved without any intervention.

Infertility or subfertility tick most of these boxes. It is therefore not surprising that acupuncturists the world over claim that acupuncture can cure infertility. But is this claim based on evidence or on wishful thinking?

The U.S. Memorial Day weekend ushers in the start of the summer grilling season but  University of Missouri School of Medicine wants to throw some cold water on your flames - by warning the public about the dangers of cleaning with wire-bristle brushes.

Coupled with the International Agency for Research on Cancer (IARC) declaring hot dogs as hazardous to your health as plutonium, grilling food just got a lot less fun - unless you have any critical thinking.


It's known that many patients die after getting sepsis but it's unclear if the increased risk of death (30 days to 2 years after sepsis) is because of sepsis itself or because of pre-existing health conditions the patient had before acquiring the complication. Patients with more medical problems are more likely to develop sepsis.

Sepsis is a complication of infection. The body releases chemicals in the bloodstream to help fight off infection, but sometimes those chemicals can damage the body, leading to organ failure and a dramatic drop in blood pressure. Sepsis is treated with antibiotics and fluids.


Few alternative therapies are more divisive than homeopathy. Whenever I write about the subject, I get bucket-loads of hate mail. Somehow, homeopathy has the power to touch raw nerves and strong emotions. And it makes fallacies appear like mushrooms after the rain:

Fortifying the U.S. food supply with folic acid was not associated with a decline in certain birth defects that researchers expected to see in California, a finding likely to contribute to an ongoing debate about the future of the fortification program.

The study of more than 1.3 million California births and pregnancies spanning two decades is published in Birth Defects Research Part A. The research examines neural tube defects, which affect a baby's brain and spine, and which were the intended target of fortification with folic acid, a B vitamin. However, neural tube defects were already becoming less common before fortification began, and their decline slowed substantially after fortification was introduced, the study found.
