Many people think that eating pig trotters is a good choice, as it can supplement collagen and beautify the skin. What effect does collagen have on the skin? Can eating pig trotters really replenish collagen? How should we supplement it?

Collagen is a very important protein in the human body, mainly found in the hoof tissue. , the main component of ligaments and tendons. The function of collagen on the skin is to fill in the space between the dermis and support the skin tissue, increase the tightness of the skin, shrink the pores, and make the skin tight and elastic. Collagen is very hydrophilic, which means it can retain the skin's moisture without evaporating, and it also absorbs water to keep the skin hydrated. Seeing this, everyone feels the need to supplement collagen.

Beef tendons, pig trotters, chicken feet, fish skin, pig skin, etc. all contain collagen. It seems that eating pig trotters to supplement collagen is a good choice. However, collagen is an incomplete protein. After being eaten, it will be broken down into small amino acids in the body and then re-synthesized into the proteins needed by the human body after entering the liver. Therefore, even if you eat pig trotters, it is not guaranteed to synthesize collagen in the body. It may synthesize other proteins needed by the body. In addition, pig trotters contain collagen, as well as a large amount of fat and cholesterol. "Fat is more likely to cause obesity than carbohydrates and protein, and obesity is an important factor in all chronic diseases. Excessive cholesterol intake will increase the risk of hyperlipidemia, and excessive protein intake will increase the burden on the liver and kidneys. In order to supplement collagen, Ingesting a large amount of fat and cholesterol at the same time is obviously not worth the gain. People with chronic diseases such as hypertension, hyperlipidemia, arteriosclerosis, and liver disease must eat it with caution.

Healthy people can eat pig trotters. Make soybeans and pig's trotters together (soybeans are rich in lysine and proline), such as soybean stewed pig's trotters, peanut pig's trotters, etc. Because when the body has sufficient protein, it also needs rich lysine and proline. Amino acid undergoes a hydroxylation reaction with the help of vitamin C and becomes hydroxylysine and hydroxyproline, so that collagen can be synthesized. "When there is a lack of vitamin C, the body's collagen synthesis will be blocked, which will cause a lot of trouble. Problems can occur anywhere that collagen is needed, including bones, tendons, skin, and blood vessels. The skin is almost not fatal, but the leakage of blood vessels will be a big trouble - because the outer wall of blood vessels is connective tissue, the main component of which is also collagen. Once there is a problem with blood vessel maintenance, from subcutaneous bleeding to internal bleeding, they are all symptoms of "scurvy". Vitamin C is also called ascorbic acid, which means it can prevent this disease. "[2] Talking about the importance of vitamin C, here are some common foods rich in vitamin C: wild dates, 100g edible part contains 900mg vitamin C; fresh dates, 100g edible part contains 243mg vitamin C; Kale, 100g of edible part contains 76mg of vitamin C; guava, 100g of edible part contains 68mg of vitamin C; Chinese kiwi fruit, 100g of edible part contains 62mg of vitamin C.

Understand the process of synthesizing collagen. , everyone knows that as long as there is sufficient protein and vitamin C and other nutrients in the body, the human body can automatically synthesize collagen. In contrast, using pig trotters to supplement protein is much weaker, because many foods are high-quality protein. Sources, such as milk, eggs, fish and lean meat, etc. In short, if you want to take good care of your skin, it is not enough to do just one thing. You also need to do the following: 1. Drink more water. 2\\3 of the human body is water. Every 24 hours, the human body excretes about 1.5 liters of water through urine, and evaporates about 750 ml of water through the skin, so you must drink 1200 ml of water every day. 2. Eat a balanced diet every day. 200-400 grams of fruits and 300-500 grams of vegetables. 3. Moderate exercise. Life lies in exercise. Exercise can speed up metabolism and help eliminate toxins in the body. Exercise can improve body shape and reduce excess fat in the body. 4. Reduce skin damage under the hot sun. When exposed to the sun, use sun protection.
