Lunch meat mainly refers to some canned compressed minced meat. The main raw materials are pork and beef, and there are a lot of food additives. The nutritional value of lunch meat is still relatively rich, with a lot of water, protein, amino acids, fat, carbohydrates and some cholesterol. In addition, it contains a lot of sodium ions and potassium ions, and eating some lunch meat in moderation can effectively improve immunity, strengthen spleen and stimulate appetite, and promote intestinal peristalsis. But it is not recommended to eat too much, because the content of sodium ion is too high, which may increase the risk of hypertension.
