Hi & welcome. Sea food is an important source of Omega-3 fatty acids which have liver protective action. It can be either in form of fresh, canned or frozen sardines, salmon, mackerel, tuna, trout, blue mussels, calamari, etc. Fish oils like Cod liver oil also contains a good amount of Omega-3 fatty acids hence can be consumed. Along with sea foods listed above eat plentiful amounts of raw fruits and vegetables, especially dark green leafy vegetables and orange, yellow, purple and red colored fruits and vegetables as they contain various vitamins, anti oxidant substances which protect the liver. Avoid taking spicy foods, cigarette smoking, fatty meals, etc. Hope this answers your query.
