It’s time to stop counting the calories, and instead start promoting the nutritional value of foods if we are to rapidly cut illness and death from cardiovascular disease and curb the rising tide of obesity, say experts in an editorial published in the online journal Open Heart.
Drawing on published evidence, Drs Aseem Malhotra and James DiNicolantonio and Professor Simon Capewell argue that rather like stopping smoking, simple dietary changes can rapidly improve health outcomes at the population level.
For example, boosting omega 3 fatty acid (from fatty fish), olive oil, and nut intake have all been associated with reductions in deaths from all causes and from cardiovascular disease, within months, they say.
But clinicians have failed to act for far too long, amid an excessive focus on the calorific content of food by the food and weight loss industries, despite mounting evidence that it’s the nutritional content that matters, they suggest.
Daily consumption of a sugary drink (150 calories) is associated with a significantly increased risk of type 2 diabetes whereas daily consumption of a handful of nuts (30 g of walnuts, 15 g of almonds and 15 g hazelnuts) or four tablespoons of extra virgin olive oil (around 500 calories) is associated with a significantly reduced risk of heart attack and stroke.
It has been estimated that increasing nut consumption by two servings a week could stave off 90,000 deaths from cardiovascular disease in the US alone.
And the Action for Health in Diabetes trial shows that a…
