Everyone needs protein to build new cells and repair any damaged tissues. Without protein the body cannot function well and muscles in particular suffer.
Generally people think about protein coming from animal meat, but milk, eggs, fish, cheese are all good forms of protein. This is because the body can use most of the protein absorbed from these sources.
Plant proteins such as that from grains, cereals, fruit etc are all incomplete proteins and so they need to be supplemented with foods which have a more complete protien source.
Food which are high in amino acids are the best protein source, since amino acids determine how much of the protein can be used by the body. Half of amino acids need to be supplied in the food, the other half can be synthesized within the body from the acids already eaten. Those richest in amino acids are meat, fish, eggs and milk, so at least some of these should be eaten daily.

• Protein is necessary for building and repair of body tissues.
• It produces enzymes, hormones, and other substances the body uses.
• It regulates body processes, such as water balancing, transporting nutrients, and making muscles contract.
• Protein keeps the body healthy by resisting diseases that are common to malnourished people.
• Prevents one from becoming easily fatigued by producing stamina and energy.

Protein is found in muscles, bone, haemoglobin, hormones, antibodies, and enzymes, and makes up about 45% of the human body. Muscle is approximately 70% water and only about 20% protein. Therefore, increasing muscle mass requires extra water, extra energy in the form of carbohydrates (to maintain the needs of that extra muscle), and a little extra protein
