Fiona Godlee, editor-in-chief of the British Medical Journal, has a heretical short article at BMJ. I recommend you read the whole thing. It starts thusly:
More than half of adults aged over 45 will be labelled as hypertensive if new US guidelines are adopted, concludes a study in The BMJ this week (doi:10.1136/bmj.k2357). This equates to 70 million people in the US and 267 million people in China being eligible for antihypertensive drugs, a marked increase on already high rates of drug treatment for high blood pressure. Furthermore, the study calculates that 7.5 million people in the US and 55 million in China would be advised to start drug treatment, while 14 million in the US and 30 million in China would be advised to receive more intensive treatment. The evidence from trials indicates some benefit from drugs in terms of reduced risk of stroke and heart disease, but is mass medication really what we want?
Hypertension is just one of the many heads of the lifestyle disease hydra. Another is type 2 diabetes. Once thought to be irreversible and progressive, it is now known to be potentially reversible through weight loss. This is the cautious conclusion of the review by Nita Forouhi and colleagues (doi:10.1136/bmj.k2234), part of our series on the science and politics of nutrition (bmj.com/food-for-thought). Whether by calorie or carbohydrate restriction, weight loss has been shown to improve glycaemic control, blood pressure, and lipid profile and is the key to treatment and prevention of type 2 diabetes, they say.
She goes on to talk about fatty liver disease (NASH) and offers an alternative, of sorts, to pills. Good luck with that.
