Low-potassium Content Vegetables in Chronic Kidney Disease
Trial Parameters
Brief Summary
Prior observational studies have shown that higher levels of vegetables and fruits consumption are associated with lower risk of all-cause mortality in patients with chronic kidney disease (CKD). However, compared with the normal population, patients with CKD are more likely to consume less vegetables and fruits. Thus, the investigators aim to evaluate whether proving low-potassium content vegetables to this population are able to reach the recommended target of daily vegetables intake and not increase the risk of hyperkalemia.
