Protein is a vital component of a healthy diet, because every single cell in your body contains proteins. Protein is a major component of muscles, skin and organs, and proteins play crucial roles in all of the biochemical reactions necessary for life. When a person does not eat enough protein, a form of malnutrition called Kwashiorkor develops. Dietary protein deficiency is rare in developed countries, but in developing countries, famine or scarce access to food can result in widespread cases of Kwashiorkor. Several symptoms commonly result from Kwashiorkor.
Decreased Immune Function
Several other symptoms can result from not eating enough protein. Long-term dietary protein deficiency can cause a person to go into shock, which may lead to a coma. Diarrhea is also a frequent symptom of not enough protein. Increased irritability and anxiety may also occur. The liver can also become enlarged, and levels of enzymes produced by the liver may be altered.
