Final answer:
Protein blends are beneficial when different types of proteins complement each other by providing missing amino acids. This helps ensure that the body gets all the essential amino acids it needs.
Step-by-step explanation:
Protein blends can be beneficial in certain situations. A protein blend is a combination of different types of protein that complement each other by providing the missing amino acid(s) found in one type of protein with the amino acid(s) found in another type of protein. This can help ensure that you are getting all the essential amino acids your body needs. For example, if a grain is consumed at one meal, a legume could be consumed at a later meal, and the proteins would still complement each other.
