Final answer:
Including a protein source in every meal and snack ensures a continuous supply of protein in the body, providing essential amino acids for various bodily functions. So, the correct answer is option 1.
Step-by-step explanation:
The result of including a protein source in every meal and snack is that protein is available in the body continuously throughout the day. Proteins from food are essential nutrients, as they are broken down into amino acids during digestion, which the body uses to build new proteins, among other vital functions.
Adequate protein intake throughout the day ensures that essential amino acids, which need to be obtained from our diet, are available for cellular function, supporting the body's metabolic reactions, and providing a continuous energy source.
