Introduction
Nutrition is a critical determinant of immune responses and
malnutrition the most common cause of immunodeficiency
worldwide. Protein-energy malnutrition is associated with a
significant impairment of cell-mediated immunity, phagocyte
function, complement system, secretory immunoglobulin A antibody
concentrations, and cytokine production. Deficiency of single
nutrients also results in altered immune responses: this is observed
even when the deficiency state is relatively mild. Of the
micronutrients, zinc; selenium; iron; copper; vitamins A, C, E, and B-
6; and folic acid have important influences on immune responses.
Overnutrition and obesity also reduce immunity. Low-birth-weight
infants have a prolonged impairment of cell-mediated immunity that
can be partly restored by providing extra amounts of dietary zinc. In
the elderly, impaired immunity can be enhanced by modest amounts
of a combination of micronutrients. These findings have considerable
practical and public health significance.
, Definitions
Food
is that which nourishes the body. Food may also be defined as
anything eaten or drunk, which meets the needs for energy, building,
regulation and protection of the body. Intake of the right kinds and
amounts of food can ensure good nutrition and health
Nutrition
“Nutrition is the science that interprets the interaction of nutrients
and other substances in food in relation to maintenance of growth,
reproduction, health and disease of an organism. It includes food
intake, absorption, assimilation, biosynthesis, catabolism, and
excretion”.
Nutritional status
is the state of our body as a result of the foods consumed and their
use by the body. Nutritional status can be good, fair or poor.
