Dietary Patterns and Their Impact on Chronic Kidney Disease Risk
Emerging studies reveal that specific dietary patterns, including the DASH diet and Dietary Inflammatory Index, can influence the risk and progression of chronic kidney disease, offering new avenues for prevention and management.
Recent research highlights the significant relationship between dietary habits and the risk of developing chronic kidney disease (CKD). A study published online on August 5, 2025, in the journal Renal Failure, emphasizes that specific dietary indices can effectively distinguish individuals' risks for CKD. Notably, the Dietary Approaches to Stop Hypertension (DASH) diet and the Dietary Inflammatory Index (DII) stood out for their predictive power.
Researchers Xianglong Meng from the University of Electronic Science and Technology of China, alongside colleagues, analyzed data from the National Health and Nutrition Examination Survey (NHANES) spanning 2000 to 2020. They evaluated four dietary indices: the Healthy Eating Index-2020, the alternative Mediterranean Diet Score, the DASH, and the DII. The results revealed that adherence to the DASH diet correlates with a reduced risk of CKD (odds ratio 0.880), while higher DII scores associate with increased risk (odds ratio 1.099). Moreover, DII was linked to the progression of CKD severity (odds ratio 1.264).
The study further demonstrated that dietary patterns have an incremental impact on CKD risk, after accounting for factors like age, comorbidities, and lifestyle. This association was consistent across various demographic groups, including men aged over 65, non-Hispanic whites, smokers, and those with or without hypertension, diabetes, or cardiovascular conditions.
The findings support the integration of DASH and DII assessments into CKD risk evaluations and highlight their potential as targeted interventions for prevention and disease management. These dietary approaches could play a vital role in reducing CKD incidence and slowing disease progression.
This research underscores the importance of dietary choices in maintaining kidney health and offers promising avenues for improving CKD prevention strategies.
