The Relationship between Nutrition and Infectious Diseases: A Review by Sedigheh Farhadi, Roman S. Ovchinnikov

Description

This academic review paper examines the multifaceted relationship between nutrition and infectious diseases, synthesising evidence from various studies. The authors explore five key aspects: the effect of nutrition on the development of the human immune system from the embryonic stage through breastfeeding; the role of nutrition in the emergence of infections through microbial contamination of food and water, leading to diseases like cholera, typhoid, and brucellosis; the bidirectional synergy between malnutrition and infection, where each exacerbates the other through mechanisms like anorexia, reduced nutrient absorption, and metabolic disturbances; specific nutritional considerations for patients with severe immune deficiencies; and the potential link between overeating, obesity, and increased infection risk. The document details how factors such as deficiencies in protein, Vitamin A, iron, zinc, and copper can weaken immunity, while infections can concurrently induce or worsen malnutrition. It references global studies, particularly on children in developing regions, highlighting the strong association between malnutrition, diarrheal diseases, and pneumonia mortality. The review also mentions interventions like antibiotics, probiotics, and prebiotics in managing severe acute malnutrition. This comprehensive resource is highly relevant for tertiary students in public health, nutrition, microbiology, and biomedical sciences programmes, providing an authoritative overview of a critical global health interaction. It serves as excellent material for exam preparation and research, offering insights into the physiological and epidemiological connections that underpin disease burden in vulnerable populations.
