Effects of Omega-3 Polyunsaturated Fatty Acid Supplementation on Allergic Diseases in Pregnant Women and Infant

Abstract

In Westernized nations, there has been a notable rise in the incidence of allergic diseases, which has been associated with a shortage serving of omega-3 polyunsaturated fatty acids (n-3 PUFAs) in diet. Supplementing with fish oil during pregnancy is being considered as a potential method to prevent allergic diseases in offspring. It may also help modulate allergic inflammation in pregnant women by influencing the synthesis of associated inflammatory mediators. The potential biological mechanisms underlying the allergic response in pregnant women and the potential protection provided to offspring through maternal supplementation of n-3 PUFAs are complex but crucial for understanding medical interventions and trial settings. The objective of this paper is to summarize the proposed mechanisms of allergic response and the anti-inflammatory pathways executed by n-3 PUFAs in both pregnant women and their offspring, drawing from important research findings. However, the efficacy of early intervention in infants through neonatal absorption of n-3 PUFAs is still unclear. The results suggest that n-3 PUFAs-induced protection covers a wide range of allergens, including those from food, house dust, and pets, as well as asthma. Conversely, the consumption of fish oil during childhood appears to have an insignificant effect on immunological disorders.
