Macro partitioning
In men aged 56-65, dietary lipid intake (total fat, saturated, monounsaturated, polyunsaturated, cholesterol) is not significantly associated with the 16-year incidence of coronary heart disease.
For men in their late 50s and 60s, this study did not find a significant link between dietary fat intake and heart disease risk over 16 years. This does not mean diet is unimportant, but the direct link observed in younger men was not detected here. Factors like competing mortality and other age-related health issues may obscure dietary effects. Focus on overall health rather than just lipid intake.
In contrast to the younger cohort, none of the dietary lipids were associated with CHD in the older cohort.
Why this rating
Same longitudinal design and adjustments as the younger cohort, providing robust evidence for the lack of association in this specific demographic.
