Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute to this Special Issue dedicated to the critical and multifaceted topic of “Early Life Nutrition and Neurocognitive Development”.

The first 1000 days of life—from gestation to the end of the second postnatal year—represent a window of vulnerability and plasticity in the development of the central nervous system. During this period, nutrition plays a key role in influencing neurobiological processes that govern neuronal proliferation, cell migration, myelination, synaptogenesis, and synaptic pruning. An adequate intake of both micronutrients and macronutrients—particularly long-chain polyunsaturated fatty acids (LC-PUFAs), iron, iodine, zinc, choline, vitamin D, and B-complex vitamins—is essential to support proper neurocognitive development.

Nutritional deficiencies during pregnancy or early infancy have been associated with an increased risk of neurodevelopmental disorders, such as autism spectrum disorders (ASDs), attention-deficit/hyperactivity disorder (ADHD), and cognitive delay. Furthermore, early nutrition modulates epigenetic mechanisms and the gut–brain axis, exerting lasting effects on gene expression and neurobehavioral trajectories. A deeper understanding of early nutritional determinants could clarify the biological foundations of brain development and support the identification of early biomarkers and intervention targets for primary prevention of neurodevelopmental disorders in pediatric populations.  

This Special Issue welcomes original research articles and review articles. We hope that this Special Issue serves as a valuable resource for clinicians, researchers, policymakers, and anyone interested in understanding the role of early life nutrition and neurocognitive development.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Background/Objectives: The first 1000 days of life represent a critical window for growth and neurodevelopment, during which nutrition strongly influences brain development and metabolic programming. In phenylketonuria (PKU), dietary management is essential to prevent neurological impairment and later-life risk of non-communicable diseases (NCDs). This review examines current evidence on PKU from pregnancy through complementary feeding, highlighting the impact of nutritional strategies on neurodevelopmental and metabolic outcomes. Methods: This narrative review, following PRISMA guidelines, used a systematic search of PubMed and Scopus with defined PICO questions. Original research, reviews, and guidelines on PKU nutrition during the first 1000 days were included, emphasizing neurological and metabolic outcomes. Results: Articles addressed prenatal and postnatal factors in PKU. Optimised metabolic control in women with PKU is critical to prevent maternal PKU syndrome, reducing risks of miscarriage, congenital heart defects, microcephaly, and neurocognitive impairment. Pre-conception dietary management, frequent blood Phe monitoring, supplementation with Phe-free protein substitutes (PSs), micronutrients, and emerging pharmacological therapies support maternal and foetal health. Following newborn screening, early dietary treatment in infants with PKU maintains plasma Phe within safe ranges, promoting growth and neurodevelopment. Breastfeeding, combined with Phe-free infant PSs, is feasible, and complementary feeding should be introduced carefully. Frequent monitoring and tailored dietary adjustments, including second-stage PSs, support metabolic control, while data on gut microbiota remain limited. Conclusions: Early multidisciplinary interventions are crucial to optimise metabolic and neurodevelopmental outcomes during this window of opportunity. Further research is needed to address remaining gaps and optimise PKU management across the first 1000 days. Full article
