Researchers found that patients diagnosed with chronic kidney disease may make their condition worse by including too much meat or other acid-promoting foods in their diets. Scientists explained that excessive meat consumption is linked to a highly acidic environment in a body already deprived by proper elimination of acid.
The team warns that kidney disease patients who consume highly acidic diets are three times more likely to develop kidney failure than their more moderate peers.
The U.S. National Institutes of Health said that kidney dysfunction interferes with the body’s normal elimination of acids found in meat, so excessive meat eating may trigger a metabolic condition called acidosis. And the patients may make their situation even worse if they do not try to offset their high-acidic diet by consuming more fruits and vegetables, the agency reported.
According to the experts at Icahn School of Medicine at Mount Sinai, the new findings are also backed by precious studies in which alkali supplements lead to lower rate of losing kidney function in patients affected by chronic kidney disease.
The new study involved nearly 1,500 kidney disease patients over 14 years. Patients were surveyed for their dietary habits. Also, their high-acid food intake was monitored and compared with low-acid foods such as fruits and vegetables.
The team found that those on high-acid diets accelerated their speed of developing kidney failure by three times compared with those on 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,”
said Tanushree Banerjee, lead-author of the study and researcher at the University of California.
She also said that the costs and lower life quality linked to a dialysis treatment may be prevented by adopting a healthier diet which is rich in fruits and vegetables.
“The results are clear and support previous findings: the higher the dietary acid load, the faster the progression of kidney disease,”
another researcher suggested.
Scientists stressed that their findings do not prove a cause-and-effect relationship between a high-acid diet and kidney failure, but it does show that a low-acid diet rich in fruits and vegetables may prove beneficial in chronic kidney disease patients.
Currently, there are at least 26 million of Americans affected by chronic kidney disease, so the researchers hope that the new recommendations could be applied to all levels of society.
The team published their findings in the February 12 issue of the Journal of the American Society of Nephrology.
