The Skin and Protein

Protein contributes to the structure of major organs particularly the largest - the skin.

Collagen is the most abundant form of protein within the skin. In addition to collagen, protein makes up elastin, laminin and fibronectin.

Amino acids are the building blocks of protein that enable collagen's full range of functions:

• Collagen gives structural support as the most abundant form of protein in the skin.
• Elastin gives elasticity to the skin.
• Laminin is the second most abundant in the skin. It supports and anchors the epidermis to the dermis.
• Fibronectin facilitates wound healing.

There are approximately 20 amino acids. Amino acids make up proteins, but not all can be manufactured by the body. Essential amino acids are the variations of amino acids that cannot be produced by the body and must be obtained through a diet containing animal products. Seafood, poultry, dairy products, and red meats are examples of foods that supply essential amino acids. although grains and legumes do not contain all the amino acids, they can be combined to provide complete protein sources.

Moderation is key. Each food group should be proportionately included in a healthful diet.

Benefits and Uses of Protein

Proteins support many of the body's critical functions. Proteins are a key component in muscle tissue, skin, tendons, organs and bones. Proteins affect our thinking and emotions.

Proteins should be consumed with fats and carbohydrates to meet energy requirements to support critical body functions. Diets with too much protein and not enough fats and carbohydrates force the body to burn protein taking it away from the protein available to serve the body.
