Nutritional stresses include both high and low intakes of many nutrients. Both types of stress affect mucosal immunity and IgE production. IgA secretion into mucosal fluids is decreased by protein/calorie malnutrition. The effects of malnutrition on IgE production may result in elevation of IgE levels. T-cell regulation is critical for IgE and IgA antibody synthesis. Malnutrition suppresses T-cell function. High intakes of vitamin A and E can also alter T-cell action, cancer resistance, and perhaps IgE and IgA production.
