Why is a starving individual more susceptible to infectious disease than a well-nourished individual?

A starving individual has a weakened immune system due to nutrient deficiencies, which impair the body's ability to produce antibodies and other immune cells essential for fighting infections. Malnutrition can also reduce the production of cytokines and other signaling molecules that coordinate immune responses. Additionally, a lack of essential vitamins and minerals can hinder wound healing and overall health, making it easier for pathogens to invade and thrive. As a result, malnourished individuals are at a higher risk of contracting Infectious Diseases and experiencing severe complications.
