Fruits and Vegetables Beneficial for Kidney Patients
Chronic kidney disease (CKD) patients with severe metabolic acidosis are treated with alkali supplementation therapy to help the kidney remove excess acid in the body by way of urine. With the recent study, adding fruits and vegetables to the diet may help patients with CKD to protect their kidneys due to its alkali content.
The study will be published in the upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN).
The study involved 71 patients divided into two groups. The research team of Nimrit Goraya, MD and Donald Weson, MD gave oral alkaline medication to one group while the other group was given increased fruits and vegetables in their diet. The treatment lasted for one year and was administered to reduce acid in the body by half.
The study showed that both treatments had a favorable outcome by reduction of urinary kidney injury markers, according to Dr. Weson. Both groups have the same kidney function after one year. The patients’ PTCO2 (plasma total carbon dioxide) increased in both groups thereby reducing the metabolic acidosis. However, the PTCO2 was higher in patients treated with bicarbonate. They also found that blood potassium remained the same in both groups even with the rich potassium content of fruits and vegetables.
It was noted however, in an accompanying editorial, that only patients who wish to remove intake of pills may benefit from this study as there are other patients who may find it difficult to follow a diet high in fruits and vegetables and would prefer taking supplements.
