Nutrients in our diet are the essential substrate for all cellular function of our body. Modern dietary habits are main causative factors for many non-transmissible chronic diseases (such as allergy, autoimmunity, obesity, cardiovascular diseases and cancer), and could facilitate the occurrence of infectious diseases. Just as particular nutrients make us sick, proper nutrition is one of the most effective and least costly ways to decrease the burden of numerous diseases and associated co-morbidities modulating the immune response.
The potential to modulate the activity of the immune system by interventions with specific nutrients is termed “Immunonutrition” . This concept may be applied to any situation in which an nutrients are used to modulate the immune system functions.
Thus, “Immunonutrition” is an emerging and multidisciplinary research area comprising several aspects related to nutrition, immunity, inflammation, infection, and body health with several interactions with microbiome, endocrine, nervous and immune systems.
