Renal failure is mainly determined by a decrease in glomerular filtration rate, the rate at which blood is filtered in the glomeruli of the kidney. Kidney failure can happen very suddenly (called acute renal failure) or slowly over time. In most cases, kidney failure is permanent. Symptoms of kidney failure are due to the build-up of waste products in the body that may cause weakness, shortness of breath, lethargy, and confusion. Inability to remove potassium from the bloodstream may lead to abnormal heart rhythms and sudden death. Initially kidney failure may cause no symptoms.
(HealthDay News) -- Patients struggling with chronic kidney disease who routinely consume meat-rich, highly-acidic diets may boost their risk for kidney failure, according to research published online Feb. 12 in the Journal of the American Society of Nephrology.
Tanushree Banerjee, Ph.D., of the San Francisco General Hospital, and colleagues conducted a nutritional analysis of 1,486 kidney disease patients over a roughly 14-year period. All were participants enrolled in a large U.S. government health study. The researchers tracked each patient's intake of high-acid foods such as meat, as opposed to their intake of low-acid foods such as fruits and vegetables.
The researchers found that those who consumed high-acid diets appeared to face triple the risk of kidney failure compared with those who consumed low-acid diets.
"Patients with chronic kidney disease may want to pay more attention to diet consumption of acid-rich foods to reduce progression to kidney failure, in addition to employing recommended guidelines such as taking kidney-sparing medication and avoiding kidney toxins," Banerjee said in an American Society of Nephrology news release. "The high costs and suboptimal quality of life that dialysis treatments bring may be avoided by adopting a more healthy diet that is rich in fruits and vegetables."
