In a study of "Beneficiary effect of dietary soy protein on lowering plasma levels of lipid and improving kidney function in type II diabetes with nephropathy" by L Azadbakht, R Shakerhosseini, S Atabak, M Jamshidian, Y Mehrabiand A Esmaill-Zadeh, researchers found that The significant reduction that was seen in proteinuria in this study could be attributed to reduction of glomerular filtration rate, intraluminal pressure and increased glomerular resistance. The different results in different studies could contribute to the different amounts of protein consumption and the existence of patients in different stages of nephropathy. As a result of reduction in urinary urea nitrogen and proteinuria, it is estimated that soy protein intake could improve renal function in these patients. This point is noticeable in kidney disease also. Although soy-protein intake may effectively decrease the hyperfiltration that antedates the onset of proteinuria in type I and type II diabetes, it may not protect from the hypertensive damage to the kidneys that commonly occurs in type II diabetes patients.
Remember that study only provide us the evident of potential use of soy in treating the indicated diseases, clinical trial will need to confirm them.
