Human milk is a rich source of immunomodulatory factors that influence the development of the infant immune system, including susceptibility to allergic diseases. Among these components, milk antibodies have been extensively studied for their role in protecting against infections; however, their potential contribution to allergy prevention may be equally important. The mechanisms of protection include allergen exclusion, enhanced and targeted antigen presentation, immune modulation via shaping of the infant gut microbiome, and direct regulation of gut immune responses.
The vision of the Nutrition in Early Life team is to work together with the community to produce quality research, for improving our knowledge of how a mother’s diet during pregnancy and breastfeeding can improve both her and her child’s health.
The predisposition to food allergy development and the induction of allergen-specific immune responses appears to be initiated early in infancy. Early exposure to food allergens, such as peanut and cashew nut, via human milk is likely important in initiating oral tolerance and reducing risk of food allergy development. This trial aims to determine if the risk of developing peanut and cashew nut allergy during infancy can be reduced by a high peanut and cashew nut maternal diet during lactation.
The dramatic rise in allergic disease has occurred in tandem with recent environmental changes and increasing indoor lifestyle culture. While multifactorial, one consistent allergy risk factor has been reduced sunlight exposure. However, vitamin D supplementation studies have been disappointing in preventing allergy, raising possible independent effects of ultraviolet (UV) light exposure.
