Study finds no Direct Association Between Cholesterol Intake and Chronic Kidney Disease Risk
A recent investigation exploring the link between cholesterol intake and the risk of chronic kidney disease (CKD) has yielded intriguing insights, suggesting a nuanced relationship between dietary cholesterol and CKD risk. This study was published in the journal of Nutrition Metabolism and Cardiovascular Diseases by Haekyung Lee and colleagues.
The study, utilizing data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2019-2021 and the Korean Genome and Epidemiology Study (KoGES), aimed to examine the potential association between cholesterol intake and CKD risk. Cholesterol intake was assessed through a 24-hour recall food frequency questionnaire, and participants were categorized based on their cholesterol intake levels.
Results from the KNHANES revealed a modest association between higher cholesterol intake and increased serum levels of total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterol. However, despite this link between cholesterol intake and altered serum cholesterol levels, the study did not find a significant association between cholesterol intake and the prevalence of CKD in the KNHANES dataset, regardless of participants having a history of hypercholesterolemia.
