Higher dietary and serum intake of linoleic acid and total polyunsaturated fatty acids (PUFA) is associated with significantly lower cardiovascular disease (CVD) mortality in middle-aged men.
For middle-aged men, prioritizing the quality of fats over the total amount consumed is crucial for heart health. Specifically, increasing intake of polyunsaturated fatty acids (PUFA) and linoleic acid—found in foods like vegetable oils, nuts, and seeds—and replacing saturated fats with these unsaturated fats is associated with a significantly lower risk of dying from cardiovascular disease. Total fat quantity alone is not a predictor of risk.
Men with an energy-adjusted dietary intake of linoleic acid (relative risk [RR] 0.39; 95% confidence interval [CI], 0.21-0.71) and PUFA (RR, 0.38; 95% CI, 0.20-0.70) in the upper third were less likely to die of CVD than men with intake in the lower third after adjustment for age.
Why this rating
Large prospective cohort study (n=1551) with long follow-up (15 years) and adjustment for multiple confounders, though observational design limits causal inference.
