Study finds no Direct Association Between Cholesterol Intake and Chronic Kidney Disease Risk

In the KoGES dataset, which included a median follow-up of 11.4 years, researchers found that cholesterol intake was not significantly associated with the incidence of CKD. This held true for individuals both with and without hypercholesterolemia. Egg consumption, often a source of dietary cholesterol, also showed no significant association with the risk of incident CKD.

The study's findings challenge the conventional notion of a direct correlation between cholesterol intake and CKD risk. Despite observing an association between cholesterol intake and altered serum cholesterol levels, researchers did not find a direct link between dietary cholesterol and the prevalence or incidence of CKD. These results suggest that solely reducing cholesterol intake may not suffice in preventing CKD development.

The study's outcomes signal the need for a more comprehensive understanding of the multifaceted factors contributing to CKD risk. While dyslipidemia remains a known risk factor for CKD, this study suggests that focusing solely on dietary cholesterol intake might not effectively mitigate CKD risk. Further research is warranted to explore additional dietary, lifestyle, and physiological factors contributing to CKD development.
