Pork skin is a high-collagen food, and eating it is good for the body.

Pork skin contains a large amount of collagen protein, which can be converted into gelatin during the cooking process. Gelatin has a network space structure, which can bind a lot of water and enhance cell physiological metabolism. It is the main component of protein in pig skin. It is collagen, accounting for about 85%, followed by elastin. Biological research has found that collagen protein is related to the ability to bind water. If the human body lacks this kind of collagen, which is a biological macromolecular glue substance, the mechanism of water storage in cells in the body will be disrupted. The amount of water bound to cells is significantly reduced, and the human body will become "dehydrated", which can cause dryness, scaling, loss of elasticity, wrinkles, and life-threatening consequences. Pig skin is sweet in taste, cool in nature, has the functions of nourishing yin and replenishing deficiency, clearing away heat and soothing the throat. In modern times, scientists have discovered that regular consumption of pig skin or pig trotters can delay aging and fight cancer. Because pig skin contains a large amount of collagen, it can slow down the aging of body cells. It is especially suitable for patients with yin deficiency and internal heat, sore throat, low fever and other symptoms.
