Eat less meat. Protein is the main component of body cells. Once protein is lacking for a long time, people's skin will lose its elasticity, become rough and look particularly old, indicating that protein is an essential nutrient for human beings. 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. These acidic substances have a strong stimulating effect on the skin and internal organs, hinder the normal metabolism of the skin and affect the bodybuilding of the skin. It is generally believed that rough skin is often caused by the increase of creatine content in blood. Therefore, many people advocate a reasonable mix of meat and vegetables. Adjust the proportion of meat and vegetables according to the different stages of human growth and development. Generally speaking, eating vegetarian food after adulthood, getting as much cystine and tryptophan as possible from plant protein to prevent skin roughness and keep skin moisture content at around 10% can delay skin aging and change the condition of skin roughness.
