How Can Kidney Disease Patients Cut Prescription Costs in Half?

People with kidney disease improved their blood pressure and cut medicine expenses in half after adding more fruits and vegetables to their diet, in a study presented Wednesday at the American Heart Association’s High Blood Pressure 2016 Scientific Sessions.

“It was remarkable that we achieved better blood pressure control using fewer drugs and without forcing people to change their diet completely,” said Nimrit Goraya, M.D., study author and program director for nephrology at Baylor Scott & White Health in Temple, Texas. “Instead, we provided food for the entire family so they could add fruits and vegetables to what they normally eat. This was important because many of these patients lived in neighborhoods without access to fruits and vegetables through local food banks or grocery stores.”woman, woman with kidney disease

Diseased kidneys are less able to eliminate acid from the body, which can create abnormally high levels in the blood — a condition called metabolic acidosis. People with kidney disease are often treated with sodium bicarbonate, or baking soda, to neutralize the excess acid. Because many fruits and vegetables naturally reduce acid after they’re digested, metabolic acidosis can also be treated by increasing fruits and vegetables in the diet.Woman eating healthy salad near the river

In the study, researchers compared blood pressure control in patients who received acidosis treatment via sodium bicarbonate fruits and vegetables to patients who didn’t receive acidosis treatment. All patients (36 in each group) were treated with medications to reduce their systolic (upper number) blood pressure to less than 130 mm Hg.
