Objective: This study was carried out to determine the effects of fermented food in maternal diet during pregnancy on neonatal and infant health. Introduction: Fermented food consumption positively affects microbiota development. It is widely acknowledged that maternal microbiota is a crucial component in the microbiota formation of the newborn. However, the short-term and long-term effects of fermented food consumption during pregnancy on newborns/infants have not been fully investigated so far. Inclusion criteria: The study included studies that were randomized controlled, quasi-experimental, pre-test and post-test controlled, cohort, descriptive and qualitative studies published in English with full-text access and with “moderate” or “strong” scores in quality assessment. Methods: The researchers conducted research on Pubmed, Google Scholar, Web of Science, Scopus, Clinical Keys, Cochrane and Ebsco-Host databases without any time limitation. Results: As a result, 1419 articles were reviewed and five studies were selected among which two studies demonstrated that fermented food consumption during pregnancy may reduce the risk of atopic dermatitis in the infant, and another study indicated that it may reduce the risk of food protein-induced allergic proctocolitis. One cohort study also reported that fermented food consumption during pregnancy improved sleep duration while another cohort study pointed out that it increased the birth weight of infants. Conclusion: Evidence supports the positive effects of including fermented foods in pregnancy nutrition on neonatal and infant health. Fermented products can be added to the daily diet as an alternative to probiotic supplements. By adding these foods to the nutritional guidelines, awareness of pregnant women can be raised. |
