Ingestion of prebiotics during pregnancy and lactation may have immunomodulatory benefits for the developing fetal and infant immune system and provide a potential dietary strategy to reduce the risk of allergic diseases. We sought to determine whether maternal supplementation with dietary prebiotics reduces the risk of allergic outcomes in infants with hereditary risk.
Improving maternal gut health in pregnancy and lactation is a potential strategy to improve immune and metabolic health in offspring and curtail the rising rates of inflammatory diseases linked to alterations in gut microbiota. Here, we investigate the effects of a maternal prebiotic supplement (galacto-oligosaccharides and fructo-oligosaccharides), ingested daily from <21 weeks' gestation to six months' post-partum, in a double-blinded, randomised placebo-controlled trial.
Common food allergens have been detected in breast milk with wide inter-individual variations in concentrations. As maternal factors, such as age, smoking, and body mass index have been associated with breast milk composition, we aimed to identify maternal characteristics associated with the concentration of food allergens in breast milk.
The Australasian Society of Clinical Immunology and Allergy (ASCIA) Guideline: Infant Feeding for Food Allergy Prevention is an update of the 2016 ASCIA guideline. This updated guideline provides recommendations specifically in relation to infant feeding for food allergy prevention.
Little is known about how sun exposure may affect the maternal skin barrier during pregnancy when many hormonal and physiological changes occur. In this longitudinal observational study, 50 pregnant women were recruited at 18-24 weeks' gestation, 25 in summer-autumn, and 25 in winter-spring. At three time points in pregnancy at 18-24, 28-30, and 36-38 weeks' gestation, participants completed a validated sun exposure questionnaire and had skin permeability and surface pH measured on the volar forearm.
Nutrition is a modifiable lifestyle factor that may play a role in allergic disease prevention. This article summarizes current evidence on the antenatal diet as a consideration for strategies to prevent child food allergy. As eczema in early infancy substantially increases the risk of food allergy development, the effects of maternal dietary intakes during pregnancy on infant eczema outcomes will also be discussed.
Pregnant women are advised to take folic acid (FA) supplements before conception and during the first trimester of pregnancy. Many women continue FA supplementation throughout pregnancy, and concerns have been raised about associations between excessive FA intake and adverse maternal and child health outcomes.
Iron deficiency (ID) is the most common nutritional deficiency affecting young children. Serum ferritin concentration is the preferred biomarker for measuring iron status because it reflects iron stores; however, blood collection can be distressing for young children and can be logistically difficult. A noninvasive means to measure iron status would be attractive to either diagnose or screen for ID in young children.
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.
Australia has one of the highest rates of food allergy, anaphylaxis hospital admissions and anaphylaxis fatalities worldwide. These trends and sustained advocacy prompted a 2019 Parliamentary Inquiry into Allergies and Anaphylaxis. Among 250 submissions, the Centre for Food Allergy Research called for a national research-coordinating centre and comprehensive allergy research funding.
