Proteins are essentials to keep the body going. They are long chains of amino acids, which are important molecules needed for different body functions. Protein is a component of every cell in your body. The body uses it to build and repair tissue; make enzymes, hormones and other body chemicals; and help build bones, muscles, cartilage, skin and even blood.
1. Sudden muscle weakness or pain can be a sign that your diet lacks the recommended amount of protein.
2. Your hair is comprised mostly of a protein known as keratin, and this mineral is important for hair health.
3. Craving sweets is especially common in people who are not eating the recommended amount of protein. The cravings may suddenly occur more frequently, and even after eating something sweet, you’re never quite satisfied.
4. Protein plays an important role in keeping fluid from accumulating in tissues, especially in the feet and ankles, by holding salt and water in the blood vessels.
5. Protein helps keep your immune system functioning properly, as the immune cells are mostly made from proteins.
