For example, this article from US News states that eating too much sodium leads to high blood pressure. Except it doesn't. A dietary reduction in salt can lead to a whopping 1.1 to 5 mmHg at *most*, if you believe meta-analysis. I'm completely underwhelmed. Most high blood pressure is genetic and diet has very little to do with it. If your blood pressure is high you need medication. That's about the only thing you'll hear me say that you need medicine for.
From the article:
"As a family doctor, I've observed that more and more of my practice is devoted to preventing and treating nutrition-related disorders such as high blood pressure, obesity, and diabetes. So I had hoped that the new dietary guidelines would provide me with concrete strategies for helping change my patients' eating habits for the better."
Why don't these doctors do some research instead of relying on Big Brother, er, I mean the government to tell them what to tell their patients? I guess they're too busy to read anything. Or to think for themselves. I find all kinds of interesting information simply searching Science Direct or even google. If they'd recommend to their patients to eat low-carb or paleo, most of their patients' health problems would improve and/or resolve themselves. In fact, I'd bet money on it. I'd even bet a million dollars. I could definitely use a million bucks.
Maybe they're scared? Taubes said in Why we get fat that no doctor was ever sued for recommending a low fat diet. I guess the acceptable killing of patients via the low fat nonsense is preferable to a lawsuit.
