Government Health Guidelines Are Wrong

After decades of trying to convince us that we need to be vegetarian, new studies are showing that the conventional government issued health guidelines are wrong. From the Guardian:
Could eating too much margarine be bad for your critical faculties? The "experts" who so confidently advised us to replace saturated fats, such as butter, with polyunsaturated spreads, people who presumably practise what they preach, have suddenly come over all uncertain and seem to be struggling through a mental fog to reformulate their script.

Last week it fell to a floundering professor, Jeremy Pearson, from the British Heart Foundation to explain why it still adheres to the nutrition establishment's anti-saturated fat doctrine when evidence is stacking up to refute it. After examining 72 academic studies involving more than 600,000 participants, the study, funded by the foundation, found that saturated fat consumption was not associated with coronary disease risk. This assessment echoed a review in 2010 that concluded "there is no convincing evidence that saturated fat causes heart disease".

Neither could the foundation's research team find any evidence for the familiar assertion that trips off the tongue of margarine manufacturers and apostles of government health advice, that eating polyunsaturated fat offers heart protection. In fact, lead researcher Dr Rajiv Chowdhury spoke of the need for an urgent health check on the standard healthy eating script. "These are interesting results that potentially stimulate new lines of scientific inquiry and encourage careful reappraisal of our current nutritional guidelines," he said.

Chowdhury went on to warn that replacing saturated fats with excess carbohydrates – such as white bread, white rice and potatoes – or with refined sugar and salts in processed foods, should be discouraged. Current healthy eating advice is to "base your meals on starchy foods", so if you have been diligently following that dietetic gospel, then the professor's advice is troubling.
