foods with collagen

Collagen is a type of protein that is abundant in our body but whose presence decreases as we age. Formed by different combinations of amino acids such as glycine, arginine or proline, this fibrous protein is essential for the maintenance of connective tissue and plays a fundamental role in the good condition of our basic structures: bones, ligaments, skin… As the years go by, the capacity for collagen production is reduced, favoring the onset of cell deterioration, something that can be delayed with healthy lifestyle habits and also with a balanced diet, which includes foods that provide it or help increase its production. Do you want to know what are the foods with collagen? Discover them in this OneHOWTO article and make them part of the healthiest menus that help you stay young for longer.

Natural gelatin , which is obtained mainly from animal bones and cartilage, is a common ingredient in different food preparations, especially traditional gelatin desserts, which are actually pure protein essential for the formation of collagen.

In this other article we explain more about what gelatin is made of .

There are three components present in green asparagus that make them an ideal food to increase collagen levels, favoring its synthesis: magnesium, vitamin C and arginine, which contains its vegetable protein. The latter is one of the amino acids that cannot be missing to maintain collagen synthesis and the health of our skin.
