Protein Use
- Your body uses protein from food like chicken breast by breaking it down into amino acids.
- Nine essential amino acids must be consumed daily, while the body can produce the other eleven.
Protein's Role
- Protein builds various tissues in the body, not just muscle, requiring continuous replacement.
- Adults must synthesize 250-300 grams of new protein daily to maintain tissues and organs.
Muscle Protein Synthesis
- Consuming protein helps build muscle tissue through a process known as muscle protein synthesis.
- This process involves converting consumed amino acids into muscle tissue.
