Therefore, under the guidance of traditional ideas, many people only regard meat as an important source of protein. In fact, this is an incomplete view. Because under certain conditions, protein of meat, fish, shrimp and crab can easily cause skin allergy and damage skin health. In addition, in the process of decomposing protein and fat, the human body will produce acidic substances such as sulfuric acid and lactic acid, which will make the blood acidic.

If the skin is rough and the hair follicle keratinized papules are all over the body, you should eat more vegetables rich in vitamins A and D, such as carrots, lotus roots, spinach and soybean sprouts.
