A vegetarian diet and reduce phosphorous levels in patients with kidney disease to below toxic levels.
People who suffer from kidney disease cannot get rid of phosphorous which is found in dietary proteins and is a common food additive.
Kidney patients have to limit their phosphorous intake because high levels of the mineral can lead to heart disease and death.
The results suggest that eating vegetables rather than meat can help patients with Chronic Kidney Disease (CKD) to avoid accumulation toxic levels of the mineral in their bodies.
A group of patients followed a vegetarian diet for one week followed by the opposite diet two to four weeks later. Blood and urine tests were performed at the end of each week on both diets.
While there was equal protein phosphorous concentrations in the two diets, on the vegetarian diet patients had lower blood phosphorous levels and decreased phosphorous excretion in their urine.
The authors concluded that the source of protein in the diet has a significant effect on phosphorous levels in patients with CKD.
“These results, if confirmed in longer studies, provide rationale for recommending a predominance of grain-based vegetarian sources of protein to patients with CKD. This diet would allow increased protein intake without adversely affecting phosphorous levels”.
The study is published in the Clinical Journal of the American Society of Nephrology.
