Sorry to get distracted from my series on what causes heart disease, yet again. However, I felt the need to blog about this article published in the
BMJ on the 12
th April 2016.
A group of researchers went back through the data from the Minnesota Coronary Experiment run between 1966 and 1973 in the US - on many thousands of participants. They were, in part stimulated to do this because they had previously looked at the Sydney Diet Heart Study 1966 - 73. In their own words:
'Our recovery and 2013 publication of previously unpublished data from the Sydney Diet Heart Study (SDHS, 1966-73) belatedly showed that replacement of saturated fat with vegetable oil rich in linoleic acid (a polyunsaturated fat) significantly increased the risks of death from coronary heart disease and all causes, despite lowering serum cholesterol. Our recovery of unpublished documents and raw data from another diet-heart trial, the Minnesota Coronary Experiment, provided us with an opportunity to further evaluate this issue.'1
To make this clear. The Sydney Diet Heart Study (SDHS) was set up to show that replacing saturated fat with unsaturated fat would reduce the risk of heart disease The original researchers who set up and ran the SDHS did not fully publish their data at the time (one can only speculate as to why this may be so).
When this current group of researchers finally managed to get hold of the full data from the SHDS, it was found that replacing saturated fat with polyunsaturated fat did lower cholesterol, however:
REPLACEMENT OF SATURATED FAT SIGNIFICANTLY INCREASED THE RISK OF DEATH FROM CORONARY HEART DISEASE AND ALL CAUSES.I am not normally a great fan of capitalisation, and using bold, but I think this statement needed that treatment.
Comment: People don't need a novel treatment strategy for obesity and sugar addiction that will make pharmaceutical companies lots of money. They just need to cut back on the carbs, and eat more fat. See also:
