Proteins are a part of every cell, tissue, and organ in our bodies. The protein we eat is broken down by amino acids that are later used to replace proteins in our bodies. These proteins include meats, poultry, fish, eggs, nuts, seeds, milk and milk products.

In small children a pure protein deficiency can occur. This is called protein-energy malnutrition (PEM) also can refer to a continuum of conditions ranging from pure protein deficiency called kwashiorkor, to an energy deficiency called marasmus. Both of these deficiencies can affect the growth of the body and skin cells because structural proteins are not available to build on. An overconsumption can lead to kidney problems, high blood pressure, and sometimes even cancer.
