1, foods rich in collagen
1, pig's feet, pig's skin and bones all have a thick layer of colloid, so the taste is very soft, and at the same time it tastes very elastic and quite sticky. This is collagen. Collagen should belong to the protein family, and it is a kind of biological polymer, which is composed of 18 amino acids except tryptophan and cysteine and has a high content. Collagen is the main component of human skin, bones, tendons, cartilage and blood vessels, among which the proportion of collagen in skin is as high as 70%-80%, so collagen has good functions of moisturizing, nourishing, brightening, firming, anti-wrinkle and repairing the skin.
2. There are many foods rich in collagen, such as chicken feet, pig tails, pigskin, pig's trotters, soft-shelled turtles and fish. Especially in animal skin and cartilage, the content of collagen is higher.
3. In addition to common pig's trotters and skin, collagen-rich foods include beef tendon, chicken feet, chicken wings, chicken skin, fish skin, shark's fin and cartilage. The "aspic" and "fish jelly" formed by cooking and cooling these foods are gels formed by boiling collagen into sol with water and then cooling.
4. Of course, foods rich in collagen also include the most important fish. The structural composition of fish collagen is the closest to human body, and it is the most suitable collagen with the highest absorption rate. The cartilage of deep-sea fish is also rich in fish collagen, so it makes sense that shark fin is used by ladies and gentlemen to nourish the skin.
2. How to slow down the loss of collagen?
It is necessary and effective to start with "prevention" and slow down the loss and degeneration of collagen. We can also supplement and repair collagen by improving the metabolism of skin cells.
The first is sun protection. Dermatologists believe that more than 90% of premature skin aging is caused by improper sun exposure.
Secondly, we should pay attention to a balanced diet, especially take more fruits and vegetables containing antioxidants, such as carrots, tomatoes, grapes, etc., and drink some red wine and tea in moderation to protect collagen in the skin. Try to eat three different colors of fresh vegetables and two different fruits every day. The more colorful the food, the more different kinds of antioxidants you eat. In addition, don't forget to drink some red wine and tea, which are rich in antioxidants and can protect collagen in the skin.
Finally, don't forget to avoid eating high-fat foods. High-calorie, high-fat foods, especially fried foods, are prone to produce free radicals, which will accelerate skin aging. If you eat less of these foods, it will reduce the chance of being hurt by free radicals and the risk of dark spots and wrinkles on your skin.

1, can prevent cardiovascular disease. Studies have shown that collagen can reduce blood triglycerides and cholesterol, and increase some essential trace elements in the body, so as to keep them in a relatively normal range. It is an ideal food for reducing weight and blood fat. In addition, collagen is unique in assisting the body to excrete aluminum and reducing aluminum accumulation in the body. Aluminum is harmful to human body. Studies show that the increasing number of Alzheimer's disease is related to the intake of aluminum. At the same time, collagen can accelerate the production of hemoglobin and red blood cells. It can improve circulation and is beneficial to coronary heart disease and ischemic encephalopathy.
2. It can be used as a calcium supplement food. Hydroxyproline, the characteristic amino acid of collagen, is the carrier of transporting calcium from plasma to bone cells. Collagen in bone cells is the adhesive of hydroxyapatite, which is isomorphic with hydroxyapatite to form the main body of bone. Therefore, as long as enough collagen is ingested, the normal body's calcium intake can be guaranteed, and collagen can be made into health food for supplementing calcium.
3. It can be used by special people. The root of gynecological diseases comes from endocrine disorders. Collagen can improve the troubles of gynecological diseases, and menopausal women need collagen to supply their bodies, so that menopausal women can face various discomforts more easily.

Collagen contains a lot of glycine, which not only participates in the synthesis of collagen in human body, but also acts as a central nervous system inhibitory transmitter in brain cells, so as to have a sedative effect on the central nervous system, and has a good therapeutic effect on anxiety and neurasthenia. Collagen food can inhibit protein's coagulation caused by gastric acid in the stomach, which is beneficial to the digestion of food, and also inhibits the secretion of gastric acid and pepsinogenase, which can relieve the pain of patients with gastric ulcer and promote the healing of gastric ulcer.
5. Collagen is a sensor for amoeba cells, which are responsible for important functions in body immunity, to clean up foreign bodies, so it is very helpful to prevent diseases. It can improve immune function, inhibit cancer cells, activate cell function, activate bones and muscles, and treat arthritis and soreness.
6. Prevent skin aging and remove wrinkles. With the increase of age, collagen will gradually lose, which will lead to the rupture of collagen peptide bonds and elastic nets that support the skin, and its spiral network structure will be destroyed immediately, and the skin tissue will be oxidized, shrunk and collapsed, and the skin will be dry, wrinkled, slack and inelastic. Therefore, it is necessary for women to supplement collagen.
