Learn what researchers discovered when they studied carbohydrate consumption and mortality risk in CKD.
Nutrition and its effects on chronic kidney disease (CKD) is significant for patients, healthcare providers, and researchers. Traditionally, research has supported a low-protein diet, meaning greater reliance on plant-based foods, including carbohydrates, many of which come from grains. There have been few studies, however, that investigate how carbohydrates affect CKD progression and outcomes. Learn what scientists recently discovered about the effects of a low carbohydrate diet on all-cause mortality in adults with CKD.*
Using data from the National Health and Nutrition Examination Survey (NHANES), researchers gathered data from 3,682 adult CKD patients aged 20 years or older. They analyzed the association between mortality risk and carbohydrate consumption over an average of 67 months.
The research team discovered that:
The results suggest that, in some instances, it may be appropriate for CKD patients to follow a lower carbohydrate and higher protein diet. Since the study’s findings run somewhat counter to current KDOQI nutrition recommendations for kidney health, the authors say, more research is needed in this area. Speak with your doctor or registered dietitian about whether or not a low-carbohydrate diet may be beneficial for your unique health situation.
