Can Diet During Pregnancy Change Your Gut Bacteria? Mediterranean Diet Shows Promise
Can what you eat during pregnancy really change your intestinal bacteria? New research reveals how the Mediterranean diet stimulates beneficial microbes for pregnant women, while stress reduction through mindfulness may not be enough.

In a recent study published in The American Journal of Clinical Nutrition, researchers conducted a clinical sub-analysis to investigate the impacts of maternal diet and stress levels on the maternal microbiome. Utilizing data from the randomized BCN Impact trial, the study revealed that a Mediterranean diet intervention significantly modified the composition of the maternal gut microbiota, promoting an increase in beneficial bacteria that produce short-chain fatty acids.
A mindfulness-based stress reduction program had more modest effects on the maternal gut microbiome, with some increases in bacteria associated with health, but did not significantly alter the overall microbiome structure (p = 0.094). These results highlight the maternal gut as a potential therapeutic target to improve both maternal health and perhaps influence long-term childhood health. It’s important to note that microbiome outcomes were measured as exploratory evaluation criteria, and further research is needed to determine how these changes translate into clinical outcomes for mothers and infants.
Background
Pregnancy represents a period of ample physiological changes, extending beyond the mother and developing fetus to include their resident microbial communities.Research has shown that maternal gut and vaginal microbiomes are primary sources for seeding the infant microbiota, a critical process for the infant’s immune system development and later metabolic health.
Parallel studies have established a link between diet and stress and the composition and function of the microbiome in non-pregnant adults. However, there is limited evidence from randomized trials on whether structured lifestyle interventions, such as diet and stress interventions, can deliberately shape these crucial microbial ecosystems, especially during pregnancy.
Understanding these associations would empower expectant mothers and their caregivers to optimize maternal and fetal health outcomes.
about the Study
This study aims to address this knowledge gap by conducting a sub-analysis of the Improvement of Mothers for a Better Prenatal care test in Barcelona (BCN Impact), a randomized controlled trial (parallel design) conducted at Clínic Hospital and Sant Joan deu Hospital (BCNATAL) in Barcelona, Spain. The BCN Impact trial aimed to determine if lifestyle interventions could reduce the incidence of small-for-gestational-age (SGA) newborns.
