Meat is not a good source of protein because it does not provide the body with all the essential amino acids.
tankabanditka [31]

Answer: False.

Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.

These are-  Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.

Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.
