Limit meat-rich diets, increase fruits and vegs intake to protect your kidneys

A new research has revealed that for patients with chronic kidney disease, diets with a high acid content may increase their risk of developing kidney failure.

Researcher Tanushree Banerjee and her colleagues examined whether acid-inducing diets might play a role. Low acid load diets are rich in fruits and vegetables, while high acid diets contain more meats.

The researchers analyzed information on 1486 adults with chronic kidney disease (CKD), who were participating in the National Health and Nutrition Examination Survey III (NHANES III), a large national sample of community dwelling adults. Patients were followed for a median of 14.2 years.

The team found that higher levels of dietary acid load were strongly linked with progression to kidney failure among patients. Patients who consumed high acid diets were 3-times more likely to develop kidney failure than patients who consumed low acid diets.

Banerjee said that 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 added that 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.

The study appears in the Journal of the American Society of Nephrology (JASN).
