The science of saturated fat: A big fat surprise about nutrition?

Comment: In fact, quite a lot of what passes for science these days is proving to have "... never been sound" from climate change to vaccinations, so it's hardly surprising that much of the establishment science on nutrition has been off by a long way.

Then there is the little question of massive fraud...

The science linking saturated fats to heart disease and other health issues has never been sound. Nina Teicholz looks at how governments started advising incorrectly on diets. 

A few years earlier, when a colleague of Krauss’s had merely tried to speak about his positive findings regarding the high-fat Atkins diet, he was met with jeers and derision. One member of the audience yelled “I am absolutely disgusted that the [government] would waste my money on a study on the Atkins diet” – to the applause of many.

When Ronald M Krauss decided, in 2000, to review all the evidence purporting to show that saturated fats cause heart disease, he knew that he was putting his professional career at risk. Krauss is one of the top nutrition experts in the United States, director of atherosclerosis research at Children’s Hospital Oakland Research Institute and adjunct professor of nutritional studies at the University of San Francisco at Berkley. But challenging one of his field’s most sacrosanct beliefs – that the fats in meat, cheese and butter are bad for health – was a near-heretical act. 

Challenging any of the conventional  wisdom on dietary fat has long been a form of professional suicide for nutrition experts. And saturated fats, especially, are the third rail. But Krauss persevered and concluded in 2010, after reviewing all the scientific literature, that saturated fats could not be said to cause heart disease. In March, another group of  scientists, including faculty from Cambridge and Harvard, came to the same conclusion after conducting a similar “meta-analysis”. These were stunning results. It seemed that saturated fat, our principal dietary culprit for decades, had been unfairly convicted.

Yet the truth is there never has been solid evidence that these fats cause disease. We only believe this to be true because nutrition policy was derailed over the past half-century by personal ambition, bad science, politics, and bias.
