Abstract

Abstract: Malnutrition is a leading cause of immunodeficiency worldwide; in particular, vitamin A and protein malnutrition seem to wreak devastating effects on various types of white blood cells. This research paper undertakes a primarily qualitative approach, curating and summarizing the most cited published findings on the effects of vitamin A and protein deprivation on leukocytes, neutrophils, eosinophils, lymphocytes, monocytes, macrophages, B cells, and T cells. All were found to be decreased in serum levels and/or have diminished efficacy in those that were malnourished, statistically significant to a p  0.05. This research is relevant as it may provide another compounding variable when regarding why those of lower socioeconomic class – especially those living in food deserts and food swamps – seem to experience disease at a greater incidence and burden than their more affluent age and sex matched counterparts.
