Pig liver is rich in protein, lecithin and trace elements, which are beneficial to intellectual development and physical development. Pig liver is rich in vitamin A. Regular consumption of pig liver can gradually eliminate eye diseases. Pig liver also has a variety of anti-cancer substances, such as vitamin C and selenium, and the liver has a strong ability to inhibit cancer, as well as special substances to fight fatigue. The liver is an organ for storing nutrients and at the same time an organ for detoxification, constantly playing its detoxifying role. After being metabolized by the liver, toxic substances and detoxification products can be excreted from the body with the secretion of bile. So the normal liver itself is non-toxic and can be used safely, and a small amount can be used during a cold.
