An alarming 90% of pregnant women do not get the minimum recommended amount of choline, a nutrient vital for fetal brain formation. This widespread deficiency is largely due to a lack of public health messaging, not a lack of access to choline-rich foods like eggs.

In clinical trials, babies whose mothers took a choline supplement during pregnancy exhibited faster reaction times to visual stimuli. This is a significant early marker, as faster infant reaction time is correlated with higher IQ in adulthood.

Unlike other mammals, human infants are born with significant fat stores. This fat provides essential nutrients like DHA and a source for ketones, which are the preferred fuel for the developing brain, especially in the first few weeks of life.

A mother's protein requirements peak during breastfeeding, not pregnancy, reaching up to 1.9 grams per kilogram of body mass. This is because she is continuously creating and transferring high-quality protein to the baby via breast milk, which can deplete her own muscle mass if intake is inadequate.

Choline is crucial for forming a baby's brain in the womb, particularly areas for memory, learning, and attention. Yet, 90% of mothers don't get enough. Eating four eggs per day provides the recommended 450mg, a simple and inexpensive way to support lifelong brain development.

By the time a baby is born, all the neurons—brain cells that process information—they will have for life are already in place. Unlike other cells, neurons do not get replaced, making the prenatal period a critical, one-time window for building the brain's fundamental architecture.

Diet during pregnancy doesn't just build a baby; it actively programs their DNA by placing epigenetic "switches" on genes. These switches influence the baby's future risk for diseases like diabetes, obesity, and even psychiatric disorders, shaping their health for life.

A baby's exposure to high glucose levels in the womb can switch on genes related to diabetes. This epigenetic programming significantly increases their risk of developing the disease as an adult, independent of their later lifestyle or genetics.

Animal studies suggest that when a mother's protein intake is low, it sends an epigenetic signal to the baby to "keep your muscles small" in anticipation of a nutrient-scarce world. This programming can result in smaller muscle mass throughout the child's life.
