What foods to eat to supplement collagen

A very important protein for the human body is collagen. Collagen is in the connective tissue. Collagen has strong tensile force and is an important part of human ligaments and tendons. The main component of the human extracellular matrix is ​​collagen. Collagen makes the skin look elastic and anti-aging. We need to supplement enough collagen to make the skin look young. I usually have a lot of foods that contain collagen. In addition to the well-known collagen soup, what other foods can supplement collagen?

1. Pig’s feet

Pig skin and bones have a sticky gelatinous layer

Therefore, the taste is very soft, yet it is very elastic and sticky. This is collagen. To be precise, collagen belongs to the protein family. It is a biological macromolecular substance composed of 18 kinds of 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. The proportion of collagen in the skin is as high as 70%-80%. Therefore, collagen has excellent moisturizing, nourishing, brightening, firming, anti-wrinkle, and repair effects on the skin.

2. Meat

In addition to common pig trotters and pork skin, foods rich in collagen include: beef tendon, chicken feet, chicken wings, chicken skin, fish skin, shark fins and cartilage. The "meat jelly" and "fish jelly" formed after these foods are cooked and cooled are actually gels formed after collagen is boiled into a sol with water and then cooled.

3. Fish

Of course, foods rich in collagen also include fish. The structural composition of fish collagen is closest to that of the human body, and it is the most suitable and most highly absorbed collagen. The cartilage of deep-sea fish is also rich in fish collagen, so it makes sense that shark fins are used by celebrities to nourish their skin. In order to better release the collagen in food, the best cooking methods are stewing, boiling, roasting and making soup. It should be noted that when obtaining collagen through dietary supplements.
