How to diet for patients with diabetic nephropathy

We advice that we can take some high quality animal protein such as fish,eggs, lean meat,etc. Protein is from animal protein and plant protein, plant protein is mainly from grain,rootstock,nuts,dried fruit,etc. Animal protein is mainly from shrimp,meat,egg and milk and so on. 
What we should attention is that there is much non-essential amino acid in plant animal, Biological utilization rate is low. Overintake will aggravate the kidney burden, which is bad to prevent diabetic nephropathy. While non-essential amino acid containing is high in animal protein, utilization rate is high, nutrition value is high, especially for milk egg and seafood,protein in these food is in high quality, which is good to protect kidney.
Therefore, for earlier diabetic nephroathy treatment, apart from controlling disturbance of carbohydrate metabolism, high quality protein diet is necessary too, the common sense of earlier diabetic nephropathy is controlling blood sugar through medicine and diet.
