The effect of replacing saturated fat with mostly n-6 polyunsaturated fat on coronary heart disease: a meta-analysis of randomised controlled trials

Systematic Review With Meta-Analysis

Human

2017 May 19

This study looked at the same diet change you mentioned and found that when they only used good quality studies without other mixed-up factors, there was no real benefit for heart health. This supports your idea that earlier positive results were probably due to those mixed-up factors.

If you swap out a little bit of butter and fatty meats for healthier fats like nuts and fish oil, you’re less likely to have a heart attack or die from heart disease — it’s not about eating less fat, but choosing better kinds of fat.
