This randomized controlled trial in Ecuador examined the impact of a maternal diet based on ancestral patterns on fetal brain development. Pregnant women (n = 215) were assigned to either a control group or the Mikhuna intervention, which provided a diverse diet. The Mikhuna group showed a significantly higher percentage of women meeting dietary diversity thresholds (74.5% vs 55.8%, P = 0.004) and improved growth in fetal brain structures.
Key findings
- 74.5% of Mikhuna participants met the minimum dietary diversity threshold compared to 55.8% in the control group (P = 0.004).
- Mikhuna intervention resulted in a 0.19 cm increase in corpus callosum length compared to control.
- Gangliothalamic ovoid height increased by 0.15 cm in the Mikhuna group.
- At 35 weeks, corpus callosum Z score was 0.56 higher in the Mikhuna group.
Why it matters
This study highlights the importance of maternal nutrition on fetal brain development, suggesting that dietary interventions during pregnancy can enhance neurodevelopmental outcomes. Understanding these effects can inform prenatal care practices.
