Hi @Vio,
To answer your question, there is no special diet for people with hepatitis B. So the same recommendation apply here, eat healthy, exercise, get enough rest, avoid alcohol, fatty and highly processed foods, and avoid stress. It is good to hear that you have already stopped drinking alcohol, because that can really speed up the damage to the liver. Dark coffee has also shown to be helpful for the liver. I hope this helps, Bansah1.
