Nutritional support for immune health during infections

Abstract

Infectious diseases are common in underdeveloped and developing countries. Malnutrition plays an important role in disease etiology, remarkably increasing morbidity and mortality risks during the early stages of life, such as infancy and childhood. Nutrients such as glutamine, arginine, omega-3 and omega-6 fatty acids, zinc, selenium, iron, vitamins A, C, E, D and B6, components of breast milk, and adequate energy intake strengthen the immune system, reduce infection risk, and play a key role in combating diseases. This review highlights the importance of nutrition for the treatment of infectious diseases.
