Collagen is a tough protein that comprises approximately 30 percent of your body protein, according to the National Institutes of Health. This protein contributes to the structure and strength of your tendons, bones and connective tissues. Collagen supplies your skin with firmness, elasticity and tone. As you age, collagen production in your body declines, and your skin may lose its firmness and tone. Eating foods that contain collagen or promote collagen production may help you maintain healthy skin and tissues.
Lysine-Rich Foods
Lysine is an amino acid in your body that is essential for the production of collagen. Including lysine-rich foods in your diet may contribute to the production of collagen, according to the University of Maryland Medical Center. Protein-rich foods are particularly good sources of lysine, including meat such as red meat, poultry and pork. Other good protein-rich sources include Parmesan cheese, cod, sardines, nuts and eggs.
Plant-Based Protein Foods
Several vegetarian forms of protein can also contribute to the formation of collagen. Vegetarian products may contain lysine, which contributes to collagen formation. According to the University of Maryland Medical Center, soy products such as tofu and soybeans can contribute to collagen formation in your skin, tendons and ligaments. Other good vegetarian protein sources that help in collagen production include legumes, beans, nuts and seeds.
Foods Rich In Vitamin C
Vitamin C is an important vitamin in the production of collagen, according to the Linus Pauling Institute. A diet rich in vitamin C-containing foods may help you to maintain firm and healthy skin. Good sources of vitamin C include fruits such as oranges, grapefruits, strawberries and tomatoes. Other good sources include vegetables such as sweet potatoes, broccoli and red peppers.
