Diet high in red meat may make kidney disease worse

An estimated 26 million people in the United States have chronic kidney disease, which can lead to complete kidney failure. Once the kidneys fail, patients either need to undergo dialysis treatments three times a week or have a kidney transplant to remain alive. In 2013, more than 47,000 Americans died from kidney disease.

Diet can play a key role in whether kidney disease progresses to kidney failure, according to research conducted by a professor at the Texas A&M Health Science Center College of Medicine.

Donald Wesson, M.D., was among the authors of a study that was recently published online by the Journal of the American Society of Nephrology. The study suggests that a diet high in animal proteins – especially red meat – can worsen the progression of kidney disease.

“Our study found that patients with chronic kidney disease who consumed diets high in animal protein were three times more likely to develop kidney failure than patients who consumed diets high in fruits and vegetables,” Wesson says.

The findings were based on data collected from 1,486 adults with chronic kidney disease who were participating in the National Health and Nutrition Examination Survey III. The study is believed to be the largest one to look at the long-term impact of diet on kidney disease in humans.

Wesson explains that when humans eat animal proteins such as red meat, the body metabolizes these proteins into acids. The kidneys produce substances to help the body rid itself of this acid, but these substances can hurt kidney function if they remain at high levels in the body over long periods of time.

“It’s like a double-edge sword,” Wesson says. “In the short term these substances can help the kidneys get rid of acid, but in the long-term they can reduce kidney function.”
