Undereating and malnutrition
Protein deficiency or hypo-proteinemia can link directly to what a person eats especially if a person is not having enough calories or is avoiding certain food groups. The protein deficiency due to diet-related cause might develop in the following situations:
As women require much more protein during pregnancy as compared to the normal person to support the development of the fetus, some women might develop protein deficiency. Those women are unluckily unable to get enough calories from protein sources of foods due to extreme vomiting and nausea face a higher risk of developing protein deficiency.
If a person is suffering financially and is unable to buy decent foods might suffer from the risk of protein deficiency. The consumption of low calories than the required dietary allowance (RDA) for a longer time can lead to protein deficiency as well.
Individuals who are following a restrictive diet such as the one that restricts nearly all plant and animal sources of proteins might be at a risk of developing protein deficiency.
A person having an eating disorder such as nervosa, anorexia, and bulimia nervosa can often lead to a diet that does not give the body enough protein.
