Obviously there are changes that can help to enhance your body’s ability to function better and there are foods that can hurt this process and some things that possibly are bad for your Liver especially in excess, such as foods with high Iron concentrations. Diet and nutrition generally are still controversial despite all that we read, see and hear and I don’t want to initiate a short course in Nutrition 101, especially since what I utilize is based on my own individual decisions and what I have read and studied.
But for your doctor to answer this question in a vacuum is a little suspect as well as his answering it entirely incorrectly without evaluating what your present diet is. I don’t want to draw conclusions because I did not hear the entire dialogue, however, I feel sure he was off base. I agree that herbs are drugs and should be used with the same caution as any other drugs. And some I take and most I do not. Also, you are obviously on the right track with food. Many years ago, looking for a decent main stream introduction to diet and nutrition, I read a book by Jane Brody who is or was the Health and Nutrition writer for the NY Times.
It started me off in a direction and gave me a good structural start. (Do I need a disclaimer here?). Once you have a basic understanding of how the systems work, you can then concentrate on eliminating things that are “bad for the Liver”. Also, unlike your stopping coffee, some of the benefits of diet and nutrition take a while to be felt. Did I also not mention exercise. Oh well, that is another part of this issue.
