FRIDAY, Dec. 9, 2016 (HealthDay News) — Available evidence supports clinical decision-making by patients and doctors on whole dietary approaches in chronic kidney disease, according to a review published online Dec. 8 in the Clinical Journal of the American Society of Nephrology.
Researchers analyzed seven studies that included 15,285 patients with chronic kidney disease, to assess the effects of a diet high in fruits, vegetables, fish, legumes, cereals, whole grains, and fiber.
The researchers found that in six of the studies, a healthy diet was consistently associated with a 20 to 30 percent lower rate of early death, and with 46 fewer deaths per 1,000 people over five years. But the study did not directly prove that a healthy diet would lengthen life. The team found no significant association between a healthy diet and risk of renal failure.
“Chronic kidney disease now affects about 10 to 13 percent of the adult population and substantially increases risks of cardiovascular complications and early death,” study leader Giovanni Strippoli, M.D., Ph.D., from the University of Bari in Italy, said in a journal news release. “In the absence of randomized trials and large individual cohort studies, this study is the best available evidence to drive clinical decision-making by patients and doctors on whole dietary approaches in chronic kidney disease.”
