As Taiwan enters an aging society, the number of dialysis patients is increasing year by year. In the dietary nutrition status of chronic kidney disease patients and long-term dialysis patients, malnutrition is common in patients with chronic kidney disease due to insufficient nutritional awareness of patients and caregivers and ineffective dietary intake. Therefore, providing complete dietary hygiene education for pre-dialysis and post-dialysis patients can encourage patients to make voluntary dietary changes and provide caregivers with enhanced nutritional awareness. Therefore, it is hoped that through this article, pre-dialysis and post-dialysis patients can better understand the choice of food, so as to delay the deterioration of their disease and improve their quality of life.
