Convenient, readily available and helping create a close and loving bond between baby and mother, breastfeeding is highly regarded for optimising infant health and preventing chronic disease in adulthood.
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.
Human milk oligosaccharides (HMOs) are bioactive carbohydrates abundant in human milk that shape the infant gut microbiome, yet their influence on the oral microbiome remains poorly understood. This study investigated associations between HMO concentrations and infant HMO intakes and the composition of the oral microbiome in predominantly and exclusively breastfed infants.
Food allergy affects families' quality of life, can be lifelong and life-threatening, urging the identification of early modifiable risk factors. Formula feeding in the first days of life may increase the risk of cow's milk allergy, a risk often attributed to cow's milk allergens exposure. Early formula feeding also reduces the colostrum intake, the first 3 days' milk, which is rich in bioactive compounds critical for immune and gut health. This study investigates whether partial colostrum feeding increases the risk of food allergy beyond cow's milk.
This study investigated adherence to Indonesia's Dietary Guidelines (IDG) among lactating women, examining related factors and association with nutrient intake adequacy, maternal and infant biomarkers, body mass index, and growth. Participants were lactating women (n = 220) from urban and rural West Java, Indonesia. Dietary intake (via 3-day weighed food records), anthropometry and blood samples were assessed. Adherence was evaluated using a scoring system tailored for IDG and adapted from the Healthy Eating Index to assess intake of food groups, sugar, salt, fat, water, coffee, and breakfast habits.
Human milk bacteria contribute to gut microbiome establishment in breastfed infants. Although breastfeeding is recommended throughout infancy, temporal variation in the milk microbiome-particularly beyond solid food introduction-remains understudied. We analyzed 539 milk samples from 83 mother-infant dyads between 1 week and 12 months postpartum using full-length 16S rRNA gene sequencing.
Developing dietary guidelines for lactating women presents significant challenges, due to limited evidence being available on their specific nutrient needs and the biological impacts of various dietary dimensions. Current dietary recommendations often rely on data from nonlactating women, leading to potential inaccuracies.
Although many mothers initiate breastfeeding, supplementation with human-milk substitutes (formula) during the birth hospitalization is common and has been associated with early breastfeeding cessation. Colostrum hand expressed in the last few weeks before birth, known as antenatal colostrum expression (ACE), can be used instead of human-milk substitutes. However, evidence is lacking on the efficacy of ACE on breastfeeding outcomes and in non-diabetic mothers.
Cow's milk allergy is rare in exclusively breastfed infants. To support the continuation of breastfeeding an infant after diagnosis with a cow's milk allergy, it is critical to examine the evidence for and against any form of cow's milk elimination diet for lactating mothers. In this narrative review, we highlight the lack of high-quality evidence, hence subsequent controversy, regarding whether the minuscule quantities of cow's milk proteins detectable in human milk cause infant cow's milk allergy symptoms.
