General Information
A vital nutrient that is essential for the growth, development, and function of the human body, protein serves as both an energy source and is a basic building block for muscles and tissues. In terms of providing energy and fuel, proteins have 4 kcal per gram. Proteins are comprised of amino acids, which is their most important and defining feature. The amino acids found within proteins create polymer chains, which are lined together through peptide bonds.

Sources of Protein
Protein is found in an abundance of food such as meat, dairy products, legumes, lentils, nuts, eggs, fish, and soy all being complete protein sources. Protein is also found in whole grains and cereals, like buckwheat, rye, oats, corn, wheat, rice, quinoa, however they only contain a smaller amount of protein than other sources. Foods that are poor sources of protein are sweet potatoes, yams, sugary foods, plantains and fruit.

Dietary Requirements
The body needs an ample supply of protein in order to perform well and to aid in the development of muscles and tissues as well as for providing energy. In general, the amount of protein needed within a person’s diet is directly correlated to their energy and carbohydrate intake, individual growth rate, body weight and composition, and level of physical activity.

Commonly, it has been thought that the higher the level of physical activity, as is the thought of for athletes, the higher the amount of protein consumption should be in order to maintain ideal physical performance. The more physical exertion and presence of greater muscle mass also require an increased amount of protein for sustainability. Young children require larger amounts of protein to stimulate normal growth rates and proper development. This should occur both during pregnancy and while a child is breast-feeding to provide proper nourishment.
