Brief Summary

Human milk is not a uniform body fluid, but quite the opposite, its composition changes continuously adapting to the requirements of the newborn. It can be considered as the gold standard for infants' nutrition and exclusive breastfeeding is recommended by the WHO during the first months of life. Additionally, its composition should be used as reference or guidance for defining optimal nutrient intakes for infants that cannot be fully breastfed. In that connection, the nutritional status and dietary habits/patterns of the mother, along with certain genetic traits, exert also influence over breast milk. Considering all these facts, and their great impact on (present and future) infant health, detailed information of breast milk composition is required for specific populations, covering as many factors, elements and nutrients as possible. In the present observational study, research is focused on breast milk in northwestern Spain, more precisely Galicia. In this context, the obtained data will serve to define the nutritional characteristics of breast milk from Galician women (interindividual variation), while at the same time evaluating the existence of specific features related to their particular diet (dietary factors), the Southern European Atlantic Diet (SEAD). All the variables measured in this research project will be related with breast milk composition. Expected primary outcomes can be divided as follows: fatty acid profiles, mineral composition, essential amino acid profiles, microbiota and steroid hormones. The key influencing factors taken into account are: lactation characteristics and maternal diet. Recruitment of participants is based on all the following criteria, with no exceptions: female, living in Galicia, lactating, \> 18 years old, volunteer participation, written informed consent and agreement to complete questionnaires about lactation, diet and other socio-demographic factors. Samples are collected by participants, and stored at the University of Santiago de Compostela under a coded system so that it is impossible to identify the donor from whom the sample comes, with the exception of the investigators. The project is adhered to the principles of the Helsinki Declaration. Participants are allowed to withdraw their consent at any moment of the study.
