Hepatitis B can eat sweet potatoes, but sweet potatoes do not have the role of hepatitis B treatment. Hepatitis B is an infectious disease mainly caused by hepatitis B virus with liver lesions, which is mainly transmitted through blood, body fluids and other extragastrointestinal routes. Hepatitis B patients may have symptoms such as fatigue, loss of appetite, aversion to oil and grease, liver function abnormalities, and some patients may have jaundice, fever and other manifestations. Hepatitis B patients should pay attention to the diet of low sugar, low fat, and intake of appropriate amount of protein, eat more fiber-rich food. Sweet potatoes are rich in dietary fiber, so hepatitis B patients can eat more sweet potatoes. In addition, hepatitis B patients can also eat more lean pork, noodles, peanuts, walnuts, lotus seeds, jujubes, green vegetables, winter melon, mushrooms and other foods. Hepatitis B patients should be given liver protection in treatment, such as ursodeoxycholic acid and reduced glutathione; immune-modulating treatment, such as thymopeptide; and antiviral treatment, such as interferon alpha and tenofovir.
