Protein – The Entrance to a Healthier Life

by September 22, 2013

Protein is essential to human health. Our bodies—hair, muscles, fingernails, and so on—are made up mostly of protein. As suggested by the differences between our muscles and our fingernails, not all proteins are alike. This is because differing combinations of any number of the 20 amino acids may constitute a protein. The importance of protein intake for humans has been known for a very long time.  Without it you would lack the building blocks needed for all tissue repair, critical enzymes and hormones you need for all of your metabolic functions, and antibodies that help your body defend against infections.

Proteins are vital to all living processes and undertake a wide range of functions quintessential to sustain life. Thus, proteins are one of the most important nutrients required by your body and must be consumed in adequate quantity and quality in your diet.

Protein and Our Bodies

Most of our bodies’ proteins are structural. The most obvious proteins that most of us would recognize are muscles.  Muscle tissue attaches to bone, and when they contract they allow us to move.  There is also specialized muscle that controls organ functions such as your heart contractions, digestive movements, and elimination functions.  Although bone is predominantly calcium, the mineral is held together with protein. Nerves are mostly fatty compounds, but protein is the framework that holds nerves together.  Blood vessels, our organs, and our skin all have structural proteins.

While just about every whole food contains some protein, the soybean deserves special mention for it contains all the essential amino acids and surpasses all other food plants in the amount of protein that it can deliver to the human system. In this regard, it is nearly equal to meat.

It’s important to note that most nutritionists, dieticians, and official sources agree that we need only 2.5%-10% of our calories from protein and ALL vegetables offer us more than that.
