Stunted growth
Protein not only aids in maintaining bone and muscle mass, but it also plays a key role in promoting body growth. Therefore, the insufficiency or deficiency of proteins is potentially harmful to the children whose bodies require an adequate supply of protein for steady growth. Stunting is another classic symptom of protein deficiency and malnutrition in children. According to a 2013 study, almost 161 million children suffer from stunted growth due to malnourishment. There is a strong relationship between impaired growth and low protein intake especially in children. Moreover, stunted growth is also one of the major signs of kwashiorkor in children.
