Really really appreciated, MinGu.
Sorry, I cannot type Chinese in company. My father's situation is not very bad. Since he takes anti-high blood pressure medicine and went through 4 times chemotherap, there is a damage to his kidney. He supposed to have another 2 round of chemotherapy, but becase the kidney situation, the doctor decided to wait.(there is a measure level for kidney, I had no clue of the English for it, now his this level is about 182, 2-3 weeks ago ever drop to 140). So, we are trying to find some info for the relevant diet so that we can help him.
I am very appreciated for your help here.
