Pig's trotters are nutritious and delicious. It is not only commonly used dishes, but also a good tonic. According to food and nutrition experts analyze, every 100 grams of pig's feet containing 15.8 grams of protein, 26.3 grams of fat, carbohydrates 1.7 grams. Pig's feet also contain vitamin A, B, C and calcium, phosphorus, iron and other nutrients, especially after the hydrolysis of protein in pig's feet, produced by cystine, arginine and other 11 kinds of amino acid content with the bear's paw is not the same.
From the medical point of view, pig's trotters are multi-purpose medicine. Pig's feet are rich in collagen, which is a kind of biological macromolecules composed of gel-like substances, is the composition of tendons, ligaments and connective tissue in the most important protein components. In the human body, collagen accounts for about one-third of protein. If collagen synthesis is abnormal, it can cause "collagen disease".
When bones are created, it is necessary to synthesize enough collagen fibers to form the framework of the bones, so collagen is also the "bones of the bones".
In addition, the collagen in the pig's feet is absorbed by the body, can promote the skin cells to absorb and store water, to prevent the skin from drying wrinkles, so that the facial skin appears plump and shiny. Han Dynasty famous doctor Zhang Zhongjing has a "pig skin formula", pointed out that the skin on the pig's hooves have "and blood, moisturize the skin" role. British beauty guru observation found that often eat pig's feet, can make the face long proportional, plump.
Collagen can also promote the growth of hair, nails, to keep the skin soft, delicate, shiny nails. Regular consumption of pig's trotters can also effectively prevent progressive nutritional disorders, gastrointestinal bleeding, hemorrhagic shock has a certain efficacy, and can improve the microcirculation of the whole body, which can prevent or alleviate coronary heart disease and ischemic encephalopathy. For surgery and serious illness recovery period of the elderly, is conducive to the recovery of normal physiological function of tissue cells, accelerate metabolism, delay the aging of the body.
Pig's trotters soup also has a lactation effect, for lactating women can play the double role of lactation and beauty.
However, the fat content of pig's feet is high, chronic hepatitis, cholecystitis, gallstones and other patients are best not to eat.
Every time you eat out, someone will point to the plate of pig's feet attentively to the lady at the table, said: "Girls eat more good, can beauty." Many people know that pig's feet contain a substance called collagen, but what is collagen, really as people say, eat it, you can make the skin tender and smooth, firm and elastic? Recently, an article in Taiwan's Kang Jian magazine answered these questions.
Collagen holds up the skin
One of the reasons young skin looks smooth and full, soft and supple, is that there are two substances in the human dermis -- collagen and elastin fibers -- that are kept in optimal condition when a person is young. However, about 25 years of age, the loss of collagen in the human body began to accelerate the speed of supply than depletion, coupled with ultraviolet radiation and oxidation in the body, may damage the structure of collagen, so that it loses its original elasticity, which is the wrinkles and facial skin laxity early appearance of the reason.
Collagen has a very important role to play in human skin. It has good supportive power, like the steel structure that holds up the skin tissue, and can make the skin look very plump. In addition, it has a strong ability to absorb moisture from around the environment; when it covers the skin, it prevents water from evaporating from the surface, making the moisturizing effect very significant.
No need to intentionally eat more gelatinous foods
In some gelatinous foods, like beef trotters, pig's hooves, chicken wings, chicken skin, fish skin and cartilage, contain collagen, which is definitely helpful for absorbing and replenishing this substance. However, it should be noted that most of these foods are also high in fat content and are not suitable for regular consumption.
In fact, most of the amino acids that make up collagen are non-essential and can be synthesized by the body itself. Experts suggest that people don't need to intentionally eat more of this type of food, and it's more important to eat a normal, balanced diet.
Some skin care products claim to contain collagen, saying that rubbing it in can "replenish" the skin's loss of that part of the collagen, but most dermatologists believe that they exaggerate their effect. Collagen is a large protein molecule that is difficult to pass through the surface layer of the skin, let alone reach the dermis to "replenish" the lost collagen.
How to slow down the loss of collagen
Since the existing methods of replenishing collagen, whether it is external or internal, the effect is not very good, experts believe that the "prevention" to start, that is, to slow down the loss of collagen and denaturation more effective.
The first step is to protect yourself from the sun. According to dermatology, more than 90 percent of premature skin aging is caused by improper sun exposure. Second, eat a balanced diet, especially more fruits and vegetables containing antioxidants, such as carrots, tomatoes, grapes, etc., but also more red wine and tea, which can protect the collagen in the skin.
Finally, don't forget to avoid high-fat foods. High-calorie, high-fat, and especially fried foods are all prone to producing free radicals that accelerate aging. If you can eat less of this type of food, you are reducing your body's chances of being harmed by free radicals and the risk of dark spots, wrinkles, etc. on your skin
