The protein content in meats is much higher than vegetables and fruits (fruits carrying the least) and this is why the people who want to go on high protein diet tend include a lot of vegetables but the primary point is that they have to be really careful in choosing the right kind of food. Dietary protein has a big role to play in the proper functioning of our body. Protein is needed for the muscle growth, the hair, nails, enzymes and hormones of our body. Our body is capable of producing only 8 kinds of proteins out of the total 22. This calls for getting the same from external sources and that is the dietary protein.
High protein meats are the only sources from where you can gather the adequate amount of protein for the body. It is not at all needed that you include all types of meats in your diet and choosing only the particular kinds can be highly beneficial rather than eating too many types of meats that are low in protein content. For instance, fresh meat is something that has higher protein content than the processed meat which contains much lower percentage of protein.
