Programming the Infant Gut: How Maternal and Early Life Nutrition Shape the Infant Microbiome and Long-term Health-A...

Area of Science:

• Microbiome research
• Nutritional science
• Pediatric health

Background:

• Childhood malnutrition (undernutrition, obesity, deficiencies) is a global health issue.
• The gut microbiome critically mediates the link between early nutrition and long-term health.
• Maternal diet, metabolic state, and environment shape infant microbial colonization.

Purpose of the Study:

• To explore the role of the gut microbiome in childhood malnutrition.
• To understand how maternal and early-life nutrition influence the infant microbiome.
• To identify opportunities for microbiome-targeted interventions.

Main Methods:

• Review of emerging evidence on maternal and infant nutrition and gut microbiome.
• Analysis of factors influencing microbial colonization and maturation (diet, breastfeeding, formula, xenobiotics).
• Examination of the microbiome's impact on immune, metabolic, and neurodevelopmental outcomes.

Main Results:

• Maternal diet, breastfeeding, and complementary feeding shape the infant microbiome.
• Dietary factors like fiber, fermented foods, high-fat/sugar diets, and additives influence microbial balance.
• Infant microbiome composition affects health and may contribute to intergenerational malnutrition.
• Pregnancy dietary interventions show promise for offspring health.

Conclusions:

• The early-life window is crucial for microbiome development and offers intervention opportunities.
• Integrating microbiome science into public health and dietary guidelines can combat malnutrition.
• Targeting maternal and child nutrition can break the cycle of malnutrition and promote lifelong health.
