Background and Aim
Background: The composition of breast milk (BM) is dynamic and can be influenced by maternal variables like diet and nutritional status. This study examined the association of maternal adherence to the MedDiet and total antioxidant content of BM and infant urine.
Background: The composition of breast milk (BM) is dynamic and can be influenced by maternal variables like diet and nutritional status. This study examined the association of maternal adherence to the MedDiet and total antioxidant content of BM and infant urine. Methods: We collected 350 BM samples and urine samples from their infants. The dietary intakes of the subjects were recorded using a validated 65 items-food frequency questionnaire (FFQ). The total antioxidant status of the samples was assessed using the ferric reducing/antioxidant power (FRAP), the 1, 1-diphenyl-2-picrylhydrazyl (DPPH), thiobarbituric acid reactive substances (TBARS), and thiol quantification assays. Milk protein, calcium, and triglyceride (TG) were also determined using standard biochemical kits.
Results: Subjects with the highest MedDiet scores are included in the highest tertile due to more consumption of dietary fiber, fruits, vegetables, nuts, legumes, and seeds, low-fat dairy, whole grains, and less consumption of red meat, sweetened beverages, and sodium than those in the first tertile with the lowest MedDiet scores. BM from mothers with the highest tertile of MedDiet contained significantly higher values of DPPH, FRAP, calcium and protein as well as lower TG concentration in BM compared to those in the first tertile.
Conclusion: Our findings revealed that high maternal adherence to the MedDiet can improve BM quality in breastfeeding mothers and thus promote better neonatal development.
