Saturated fat not good after all?

From here:

Quote:

The meta-analysis of over 70 studies explored the comparative impact of saturated fat (found in meat, butter, and cheese) and unsaturated fat (found in vegetable oils, nuts, and fish) on heart disease. Challenging decades of conventional wisdom, the authors reported no clear correlation between levels of saturated fat and heart problems. Brashly, they concluded: “Current evidence does not clearly support guidelines that encourage high consumption of polyunsaturated fatty acids and low consumption of total saturated fats.”

Scientists were unusually vocal in their critiques. The omissions, according to a New Zealand scientist, “demonstrate shoddy research and make one wonder whether there are more that haven’t been detected.” The authors of the study “have done a huge amount of damage,” Walter Willet, the chair of the nutrition department at the Harvard School of Public Health, told Science. Deeming the work “dangerous,” he called for a retraction.
