Complementary Feeding in Developed Countries: The 3 Ws (When, What, and Why?)

Area of Science:

• Pediatrics
• Nutrition Science
• Public Health

Background:

• Exclusive breastfeeding is recommended for 4-6 months.
• Complementary feeding (CF) introduction and practices require further attention.
• Understanding CF's impact on infant health is vital.

Purpose of the Study:

• Review current recommendations for complementary feeding (CF) in European infants.
• Discuss the health implications of CF practices.
• Highlight the importance of CF for long-term health outcomes.

Main Methods:

• Literature review of current recommendations and evidence on complementary feeding.
• Analysis of the impact of CF on infant growth, development, and disease risk.
• Synthesis of expert opinions on optimal CF strategies.

Main Results:

• Exclusive breastfeeding for 4-6 months is recommended, followed by CF alongside breast milk.
• Healthy CF practices positively influence growth, neurodevelopment, and gut microbiota.
• Adequate CF may reduce risks of infections, allergies, type 1 diabetes, celiac disease, and non-communicable diseases.

Conclusions:

• Nutritional strategies should encourage healthy CF for long-term offspring well-being.
• Future research should focus on optimizing CF timing, content, and methods.
• CF-targeted strategies are essential for preventing future health issues like obesity and chronic diseases.
