Answer:
Step-by-step explanation:
Amino acids make up proteins. They are also known as the "building blocks" of proteins.
If you eat a food containing protein, the body, specifically the digestive system, can break down the protein into amino acids. Basically, when you eat a food rich in protein, you are also eating amino acids.
A common protein rich food is meat. Since they are good sources of protein, they will provide amino acids as well. Therefore, the best answer choice is meats.
