The Claim
Dietary cholesterol intake demonstrates a U-shaped nonlinear association with all-cause mortality among US adult populations, wherein each 50mg/day increment in dietary cholesterol intake is inversely associated with mortality risk at consumption levels below 250mg/day (Hazard Ratio 0.87, 95% Confidence Interval 0.77-0.98), yet positively associated with mortality risk at intake levels of 250mg/day or greater (Hazard Ratio 1.07, 95% Confidence Interval 1.01-1.12).
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.
Eating more cholesterol might actually be linked to living longer if you eat small amounts (under 250mg daily), but eating lots of cholesterol (250mg or more daily) seems to be linked to a higher risk of dying from any cause.
See the scientific wording
Dietary cholesterol intake shows a U-shaped association with all-cause mortality in US adults: each 50mg/day increase is inversely associated with mortality at intake levels below 250mg/day (HR 0.87, 95% CI 0.77-0.98), but positively associated with mortality at intake levels 250mg/day or higher (HR 1.07, 95% CI 1.01-1.12)
What the research says
1 studyThis study directly tests whether dietary cholesterol affects death rates in US adults and finds exactly what the claim describes: lower cholesterol intake is linked to lower death rates, but higher intake above 250mg/day is linked to higher death rates.
