Products appeared in stores, which include collagen. For example, peanut paste, sweets, drinks with collagen. However, collagen is also natural in many natural protein products, although this component is not listed among the ingredients. What is it and for what?
We lose after 30
“Collagen is the most common protein in our body, it accounts for from a quarter to almost half of all the proteins of the body,” said Aif.ru A dietitian, candidate of medical sciences, senior researcher at the FIC of food and biotechnology Natalya Denisova. – It is in the muscles, skin, bones, cartilage and tendons, hair, as well as the walls of blood vessels and heart valves. It is from collagen fibrils that a frame is formed, on the basis of which our skeleton and muscles are built, almost all organs and systems of the body. Collagen formations hold cells and tissues together, give them strength. With a lack of collagen, painful changes develop in the joints, the bones are made fragile, the nails lose their shine and density, grow worse, the hair becomes thin and falls out more. ”
With age, the production of collagen decreases, which leads to the first signs of aging – the skin loses elasticity, wrinkles appear, muscles become less strong and elastic. Collagen is no coincidence called a “beauty protein.” “By the age of 30, the level of collagen is 90% of the original, since the collapse of collagen fibers begins to prevail over its formation. After 40 years, its natural loss is 1% annually. Plus, collagen fibers damage and destroys active ultraviolet radiation, ”the doctor says.
Tan and sugar kill collagen
According to studies, even with a single exposure to UV rays, when only slight redness appears on the skin (for example, the first tan at sea), the production of collagen is blocked for 48-72 hours. And after repeated exposure to the Sun, say, in two weeks in the resort, for a much longer period. Unfortunately, it is impossible to restore the synthesis of collagen in the body in an adult to the initial level – such changes are called photographs of the skin.
Also, with age, collagen is glycated (joining sugars to it). This leads to a change in the physicochemical properties of collagen fibers: their elasticity, strength and ability to absorb moisture are reduced, and the update is difficult. So too much sweet in the diet also negatively affects collagen and leads to the progression of aging processes.
How to make up for a collagen with food?
Collagen is found in various types of meat (beef, chicken), fish, fish and meat broths, egg white, gelatin. Daily use of these products in sufficient quantities will help the body get it.
However, the assimilation of collagen is affected by the duration of heat treatment (for example, the longer the meat and the higher the treatment temperature, the faster the collagen is destroyed), diseases of the gastrointestinal tract, bad habits and other causes.
“In order for the body to produce collagen in the right amount, it is important to receive a sufficient amount of vitamin C. Its sources with the diet are fresh vegetables and fruits, primarily citrus fruits, sweet pepper, rosehip, kiwi, currants and other berries. It is recommended to consume at least 300-400 g of fruits, vegetables and berries per day, ”the doctor said.
