Here’s a sobering thought: advice doctors and dietitians give diabetics worldwide makes the condition life-threatening. University of Cape Town emeritus professor Dr Tim Noakes has set up The Noakes Foundation to do independent research into issues that include diabetes. Here, looks at why conventional medical and dietetic advice on diabetes is likely to be wrong. For starters, he shows why it has little if any science to back it up. Along the way, he shows why diabetes may turn out to be the most egregious example yet of iatrogenic (doctor-caused) disease. – Marika Sboros.
