A nephrology specialist recommends maintaining a healthy weight, regular activity, vegetable-rich meals, less salt and avoiding smoking to protect kidney health. Because diabetes and hypertension are major causes of end-stage kidney disease in Korea, blood glucose and blood pressure control remain central; practical steps include around 150 minutes of moderate activity a week and reducing salt. Observational links between exercise, obesity and chronic kidney disease should not be treated as guaranteed individual prevention effects. NIDDK also notes that early damage can be symptomless and recommends testing for people with risk factors. The emphasis is coordinated risk management, not a single protective food.
