The Claim
Replacing saturated fat with mostly n-6 polyunsaturated fat in the diet does not significantly reduce the risk of major coronary heart disease events, total coronary heart disease events, coronary heart disease mortality, or total mortality in adults, as indicated by pooled relative risks of 1.06 (CI 0.86–1.31), 1.02 (CI 0.84–1.23), 1.13 (CI 0.91–1.40), and 1.07 (CI 0.90–1.26) from adequately controlled randomized trials.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Swapping saturated fats (like butter) with certain vegetable oils in your food doesn't really lower your chances of having heart problems or dying early, according to big studies.
See the scientific wording
Replacing saturated fat with mostly n-6 polyunsaturated fat in the diet does not significantly reduce the risk of major coronary heart disease events, total coronary heart disease events, coronary heart disease mortality, or total mortality in adults, based on pooled results from adequately controlled randomized trials with relative risks of 1.06 (CI 0.86–1.31), 1.02 (CI 0.84–1.23), 1.13 (CI 0.91–1.40), and 1.07 (CI 0.90–1.26), respectively, indicating no beneficial or adverse effects.
What the research says
1 studyThe study looked at swapping certain fats in the diet and found it doesn't really lower heart disease or death risk, which matches exactly what the claim says.
