Protein and amino acids are the main components of our muscles, bones, skin, tissues, and organs. When we eat protein, our body breaks it down into individual amino acids during digestion and then uses these amino acids to create new proteins where needed. Protein promotes satiety, or the feeling of fullness, more than both carbohydrates and fat. This can be beneficial for athletes who are often fueling their bodies for long stretches of time. Along with reducing appetite, eating protein temporarily boosts metabolism.
The body uses energy to digest and make use of the nutrients in food. Since protein is the building block of your muscles, eating adequate amounts of protein helps maintain your muscle mass and prevents muscle wasting. So if you walk a lot, enjoy cycling, or do any sort of exercise to stay active, you need to eat protein. Athletes and individuals with more muscle need to eat larger amounts of protein daily to maintain their higher muscle mass.
Not only does eating protein help prevent muscle breakdown, but it can also help build and strengthen muscles. Combining regular activity and exercise with high protein intake promotes muscle growth and strengthening. High-quality proteins contain all of the essential amino acids and are rich in branched-chain amino acids BCAAs.

Nutritional value of protein The nutritional value of a protein is measured by the quantity of essential amino acids it contains. Different foods contain different amounts of essential amino acids. Generally: Animal products such as chicken, beef or fish and dairy products have all of the essential amino acids and are known as 'complete' protein or ideal or high-quality protein.
Soy products, quinoa and the seed of a leafy green called amaranth consumed in Asia and the Mediterranean also have all of the essential amino acids.
Plant proteins beans, lentils, nuts and whole grains usually lack at least one of the essential amino acids and are considered 'incomplete' proteins.
