The function of your liver is to filter off the dirty metals and bio toxic stuff from your body. Therefore, it has a very high concentration of heavy metals and other dirty stuff in it, particualry if the animals you eat also have liver issues and can not effectively remove the metals themselves from their livers. For example, If you take the Tylenol, it will go through your liver and have some residues left. If you take a few Tylenols in one day, your AST and ALT (轉肝酶) will go up the next day. Eating liver will likely increase the burden of your liver (增加肝功能負擔) and is the LAST thing you want to do if you have a liver problem.
