For women, the collagen content in the skin directly determines the speed of aging. After the age of 27, the collagen in women's body began to lose a lot, so timely replenishment of collagen plays a particularly important role in delaying aging. If you don't want to buy collagen products to replenish, you can actually replenish it through some collagen rich foods in daily life. So which foods are rich in collagen?
The best effect of frozen pig skin
Pig skin is one of the most popular foods, and the most classic way for people to eat is pig skin jelly. As long as the meat skin is clean, cut into shreds, put in cooking wine and material bag and boil for about 2 hours until the meat skin is fully cooked and the soup is thick, then add salt and sugar to taste, pour into the container and cool and solidify.
You can also cut the pigskin into small dices for filling. The secret of filling the soup with fragrant and thick soup is it. Animal skin is rich in collagen, so it has the effect of moistening and nourishing skin. The pigskin can moisten the lung, and the lung is the main skin, so the pigskin has the best skin beauty effect.
Low nutritional cholesterol in fish skin
The nutritional value and nourishing effect of fish skin are similar to other skin, but the cholesterol content is the lowest. People who dare not eat other skin because of high blood fat need not worry about eating fish skin. There are many ways to eat fish skin, and the most popular one is cold fish skin. In addition, braised fish skin, spicy fish skin and garlic fish skin are also good attempts.
When making fish skin, pay attention to blanching time not too long, so as not to affect its crisp taste. People with bad stomach should not eat more fish skin, which is more difficult to absorb. If you add some vinegar, you can improve it.
In order to reduce the damage of free radicals to collagen, we should also eat more orange, carrot, tomato, grape and other foods with antioxidant function.
At the same time, animal skin contains more fat, which is better with onion, cauliflower, celery and pumpkin.
Shrimp skin Soup for shrimp sauce
The content of calcium in shrimp skin is very high, but the absorption rate is not high. The shrimp skin also contains chitin, which is the only dietary fiber in animal food. But it's not easy to eat the shrimp skin and let its nutrition be used by us. If the shrimp is small or small, it can be mashed in a blender with a shell to make shrimp paste, which is good for frying, steaming and stewing.
It is often said that the shrimp skin sold in the market is made of dried shrimp. This kind of shrimp skin is more convenient to eat. It can be used to cook soup or stir fry yellow and stir fry until fragrant. It can be used as a good seasoning with rich nutrition.

The simplest way to eat chicken skin is "fried chicken skin". First, marinate it with onion, ginger and seasoning, and then dip it in salt and pepper. Chicken skin can also be used as a separate dish, such as' mustard skin 'in Shandong,' steamed chicken skin with flour 'in Sichuan,' bamboo shoot skin with chicken skin 'in Guangdong,' preserved crab skin with chicken skin 'in Hunan,' sliced chicken skin soup with bamboo fungus' in Hunan, and 'mushroom skin soup' in Fujian.
