A good diet may deliver micronutrients such as vitamins A, B6, B12, C,
and D and minerals such as iron, copper, zinc, and selenium that have been
implicated to have key roles for supporting immunity with reducing host infections.
Most studies have shown that once the subject was infected, the immune system will
be enhanced, which will require high levels of metabolic rate, energy requirements,
different biosynthesis substances and regulatory molecules, which are obtained from
dietary sources. Consequently, a healthy diet will result in a healthy gut by achieving
well-balanced gut microbiota which enhances the immune system. The human gut
microbiota consists of two major two groups: Firmicutes and Bacteroidetes. Some of
these can beneficial, some can be detrimental to the host. Their composition can be
modified by small changes in diet when beneficially supports the body’s repair,
growth, and immunity. Dietary sources can be converted into beneficial metabolic
end-products such as short chain fatty acids, i.e., acetate, propionate, and butyrate,
fermented by the beneficial gut microbiota such as Lactobacillus and
Bifidobacterium. This is achieved by an indirect nutrient strategy using
pro/prebiotic. The gut microbiota cooperates with their hosts for metabolic and
nervous systems development, in addition to the function of the immune system
regulation via dynamic bidirectional communication known as the gut–brain axis.
Indeed, studies have shown a correlation with anxiety, pain, cognition, and mood
regulation in animal models studies, related to gut microbiota due to dietary CLICK TO VIEW
