The role of nutrition in immune response
• Nutrition has essential role to maintain immune-competence
• Nutrition factor is required by all kinds of immune system, specific as
well as nonspecific
• Disruption of a balance between intake and requirement of energy
and nutrients → Malnutrition
↓ immune-competence ↓
