Eating more eggs during pregnancy to support fetal brain development

Maternal Intake of Eggs and Infant Neurodevelopment

Not applicable Interventional University of Kansas Medical Center · NCT07583186

This test will see if pregnant women who eat 10–14 eggs per week have better fetal brain development than those who follow a general healthy prenatal diet.

What this trial studies

Pregnant women between 12 and 20 weeks' gestation who typically eat three or fewer eggs per week will be randomized to an egg-focused prenatal diet (encouraged 10–14 eggs weekly) or to a healthy prenatal diet education control. The egg group receives education about choline and other egg nutrients and support to increase egg consumption through delivery, while the control group receives general prenatal diet education. Investigators will monitor maternal nutrient intake and measure fetal neurodevelopment outcomes late in pregnancy to compare groups. The intervention targets increased intake of choline, lutein, zeaxanthin, and related nutrients found in egg yolks that are important for fetal brain development.

Who should consider this trial

Good fit: Pregnant women aged 18 or older with a singleton pregnancy between 12 and 20 weeks' gestation who currently eat three or fewer eggs per week and are willing to increase egg consumption through delivery are eligible.

Not a fit: Women with egg allergy, multiple gestation, serious illnesses likely to confound outcomes, or those already consuming more than three eggs per week are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, this could offer a simple, affordable dietary approach to increase key prenatal nutrients and potentially improve fetal brain development.

How similar studies have performed: Observational studies have linked higher maternal egg and neuroprotective nutrient intake with better fetal neurodevelopment, but randomized trials of prenatal egg supplementation are limited.
