Researchers have found that proteins in common garden peas can help fight high blood pressure and chronic kidney disease (CKD). CKD patients are actually at highest risk from the cardiovascular complications arising from high blood pressure associated with kidney malfunction.
Peas long have been recognized as healthy, containing protein, dietary fiber and vitamins. The new research focuses on the yellow garden pea, a mainstay pea variety.
Scientists purified a mixture of small proteins called pea protein hydrolysate. When researchers fed small daily doses of the protein mixture to laboratory rats with a severe form of kidney disease, the rats showed a 20 percent drop in blood pressure.
The researchers also report that consumption of the pea extract produced a 30 percent increase in urine production in the diseased rats, bringing their urine to within normal levels.
