The Claim
Replacing 5% of energy from saturated fat with polyunsaturated fatty acids is associated with a 13% lower risk of coronary heart disease events and a 26% lower risk of coronary heart disease death, based on pooled analyses of prospective cohort studies and randomized trials, highlighting the importance of fat quality over total fat intake.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.

What the research says
1 studyStudy: Coronary heart disease prevention: nutrients, foods, and dietary patterns.
The study says swapping bad fats (saturated fat) for good fats (polyunsaturated fats) helps protect your heart, which is exactly what the claim says — so it supports it.
