About 这份食疗法的功效 it is hard to draw a conclusion although I did try Budwig's diet for half a year in the summer of 2010. At least it has not coming back at this moment but, don't forget, I did change my life style completely since I was sick. It is said that the diet is good for many conditions, especially the immune system ones.I read the book by Budwig and there are only few medical terms involved, not that much at all.
For me there are tons of things the cancer patient supposed to change after he/she is sick. I had included the introduction of Budwig's diet in my series of anti-cancer life-style suggestion in this forum. You can search back to Feburary to find that series all in Chinese. The integration of all kinds of healthy life-style would be much better than just one diet, I think.
