Abstract

Background: Non-specific elevated IgE and allergies are common in children, and their prevalence is increasing. Dietary changes could be an explanation for this increase. Zinc, iron, vitamins A, C and E, and polyunsaturated fatty acids all play possible roles in the etiology and possible treatment of allergies due to their numerous immunomodulating properties. Objectives: To investigate the immunomodulating effect of recommending a nutrient-rich diet consisting of green vegetables, beef, whole milk and full-fat butter. Methods: We conducted a case-controlled, non-randomized, retrospective study. Children between the ages of 1 and 18 years with non-specific elevated IgE were included. Baseline and follow-up measurements of serum total IgE and clinical outcomes were retrospectively collected and compared for 49 children who received the dietary advice (to eat green vegetables, beef, whole milk and full-fat butter) and 56 children who did not. Results: The initial analysis showed a significantly greater decrease in IgE in the intervention group compared to the control group; a 9.2 kU/l versus a 0.1 kU/l decrease, respectively (P = 0.02). When supplement (vitamin D) use was taken into account, however, no significant difference was produced by the dietary effect alone (unstandardized coefficient = 71.3 kU/l, P = 0.16). 53.2 % of participants in the intervention group reported considerable improvement in symptoms versus 28.6 % in the control group (P < 0.001). Conclusion: Overall, the effects of nutrients and vitamins on the decrease in IgE are promising. The separate contributions of dietary advice and/or supplements need to be investigated in the future.
