Abstract:

Background: The intrauterine environment plays a critical role in shaping the long-term health and cognitive potential of the offspring. Maternal nutrition is perhaps the most significant modifiable factor influencing fetal brain development. During gestation, the rapid proliferation of neurons, synaptogenesis, and myelination require a continuous and balanced supply of specific macro and micronutrients.

Objective: This comprehensive review aims to synthesize current clinical evidence regarding the correlation between maternal dietary patterns and fetal neurodevelopmental outcomes, highlighting the critical windows of brain vulnerability.

Methods: A systematic search of peer-reviewed literature from PubMed, Scopus, and Google Scholar was conducted, focusing on longitudinal studies and randomized controlled trials (RCTs) published between 2018 and 2025.

Discussion: The review identifies key nutrients essential for neurological integrity. Docosahexaenoic acid (DHA) and Choline are found to be pivotal for hippocampal development and memory function. Folate (Vitamin B9) remains the gold standard for preventing neural tube defects (NTDs), while Iron and Iodine deficiencies are linked to significant deficits in IQ and motor skills. Furthermore, the role of the maternal gut microbiome and its metabolic byproducts in the "gut-brain axis" of the fetus is explored as an emerging area of research.

Conclusion: Suboptimal maternal nutrition, characterized by both undernutrition and the "hidden hunger" of micronutrient deficiencies in obese mothers, can lead to irreversible neurodevelopmental delays and increased risk of neurodevelopmental disorders such as ADHD and Autism Spectrum Disorder (ASD). Integrating personalized nutritional counseling into routine prenatal care is imperative to optimize the cognitive capital of the next generation.
