What is the purpose of protein in the human body?

Protein is a very important nutrient that has many functions:

Protein is critical in the production of hormones and enzymes. Enzymes are forms of protein that catalyze all chemical reactions in the body. Antibodies are made of proteins, which fight diseases and clean up foreign bodies. The carrier agents that transport oxygen in the blood are made of protein. And, of course, as we all know, protein is essential for the structure, growth, repair, and function of all the cells that make up our tissues, organs, and glands.

Protein is made from the building blocks called amino acids, some of which the body makes and some of which the body must get from outside sources. And this is the sticking point for most of us. What are the best, most nutritious outside food sources of protein? We have all been lead to believe that our best sources of protein are animal products.

We have all been duped.

Our best sources of outside protein do not come from animal products. If you research the journals and the books by experts such as John McDougall, M.D., Neal Bernard, M.D., Joel Fuhrman, M.D., T. Colin Campbell, PhD., and many others, you will discover that the best sources of protein for human health, without the excess fat, cholesterol, chemicals, animal protein and calories, come from plant foods.
