“A prominent group of nutrition researchers have once again linked saturated fats to increased coronary heart disease.
The new paper, published in BMJ, is the third paper in the past year to decry saturated fats. Along with the previous two papers, published in JACC and JAMA Internal Medicine, the BMJ paper uses data from two large observational studies to support the widely held view that high intake of saturated fat should be replaced with unsaturated fats, complex carbohydrates, or plant-based proteins. The senior author of all three papers is Frank Hu, the Harvard University nutrition researcher who has been a leading figure in the prosecution of saturated fats.
But some critics, including a BMJ editorialist, continue to raise concerns that observational data like this is not capable of demonstrating the negative effect of saturated fats. The new paper also raises additional concerns about the role of co-authors who work in the food industry.’
