The Claim
Higher saturated fat intake is associated with increased mortality from coronary heart disease (hazard ratio 1.10, 95% CI 1.01–1.21) and breast cancer (hazard ratio 1.51, 95% CI 1.09–2.09) in observational cohort studies, but the evidence is of critically low quality and likely confounded.
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.
People who eat more saturated fat, like butter and fatty meats, seem to die more often from heart disease and breast cancer, but this might just be because other things—like lifestyle or diet—are actually causing the difference, and the science isn’t very strong.

Higher saturated fat intake is associated with increased coronary heart disease mortality (hazard ratio 1.10, 95% CI 1.01–1.21) and breast cancer mortality (hazard ratio 1.51, 95% CI 1.09–2.09) in observational cohort studies, but the evidence is critically low quality and likely confounded.
What the research says
1 studyStudy: Effect of reducing saturated fat intake on cardiovascular disease in adults: an umbrella review
This study found that people who ate more saturated fat had higher rates of heart disease and breast cancer deaths, just like the claim says — even though the data isn’t perfect and might be influenced by other factors.
