Abstract
Background: The gut microbiota plays a critical role in maintaining health, influencing nutrient metabolism, immune function, and disease susceptibility. During pregnancy, maternal diet can significantly alter gut microbiota composition and diversity, potentially impacting maternal and fetal health.
Methods: This mini-review aims to answer whether maternal diet during pregnancy is associated with the composition and diversity of maternal gut microbiota. A comprehensive literature search was conducted in Embase, Scopus, PubMed, Web of Science, and Cochrane databases in May 2024. A risk of bias assessment was done.
Results: Twenty articles were selected, including randomized controlled trials, cohort, cross-sectional, and case-control studies. Which revealed that increased dietary fiber intake was consistently associated with higher gut microbiota richness and diversity. Conversely, high-fat diets were linked to reduced microbial diversity and pro-inflammatory profiles. Dietary interventions such as vegetarian and Mediterranean diets promoted a more diverse and beneficial gut microbiota composition.
Conclusion: Maternal diet during pregnancy is closely associated with changes in gut microbiota composition and diversity. These findings underscore the importance of dietary interventions in managing gut microbiota and improving pregnancy outcomes. Future research should focus on personalized nutrition strategies to optimize maternal and fetal health.
