The immune system protects the host against pathogenic organisms and acts to ensure tolerance
to self, to food and environmental components. Bovine milk, micronutrients and many nutrients
beneficially affect the host immunity. Bovine milk has many components that improve the
body immune functions. In addition, a significant mass of research now exists investigating
the role of probiotic and prebiotic in ameliorating immunity during various intestinal diseases.
Vitamins and minerals boost immunity. Micronutrient deficiency suppresses immune function
by affecting the innate T-cell mediated immune response and adoptive antibody response.
Moreover essential fatty acids, and some amino acids have numerous important influences
on immune responses. Besides, glutathione and nucleotides are important components of
immunonutrient mixes. Also, in this article, an overview of how nutrient-nutrient interaction
may affect host immunity, was discussed.
