To begin I would want to briefly speak about hepatitis.
Generally speaking any sort of inflammation of the liver is called Hepatitis. However once can broadly classify causes of hepatitis as either infectious or non-infectious. The most common and I am sure the one that you asked about is infectious hepatitis.
Infectious hepatitis is attributable to a range of viruses that have alphabetical letters attached to them for identity. Thus there is Hepatitis virus A,B,C,D and E. In the medical filed we worry a lot about type A, B and lately C. Hepatitis A is transmitted through fecal (faeces) contamination of food or water. Type B and C are spread by contact with bodily fluids like blood and thus can be spread by sexual contact or drug users that share needles.
Non-infectious causes of hepatitis include drugs, toxins and alcohol abuse.
Now to answer your question, there really isn’t any recommended dietary management for hepatitis. Maybe we encourage fluid intake and of course alcohol use MUST stop. Some people advocate for what is called a gluten free diet i.e. avoid wheat products but it can be difficult to get gluten free food outside big towns.
