Nutrition for pregnant women

During pregnancy, high-quality nutrition supports fetal development, organ formation and brain growth. Energy, protein and micronutrient needs progressively increase across trimesters.

Essential vitamins and minerals

  • Recommended intakes include: folic acid (400 µg/day min) to prevent neural tube defects
  • iron (30–60 mg/day) to prevent anemia
  • calcium (~1000 mg/day) for bone formation
  • vitamin D (15 µg/day or sunlight exposure) and DHA (200–300 mg/day) for neurological development.

Foods to limit or avoid

Avoid alcohol (strictly prohibited), raw products (meat, fish, eggs) due to infection risk, and limit caffeine to ~200 mg/day. Follow local recommendations and medical advice regarding supplements.

Nutrition for breastfeeding women

  • During breastfeeding, energy needs increase by roughly 500 kcal/day to support milk production, depending on nursing frequency and duration
  • Adequate intakes of protein, calcium, iron, iodine and vitamins (D, B12) are important
  • hydration is essential

Exclusive breastfeeding (0–6 months)

WHO recommends exclusive breastfeeding for the first 6 months, with no other liquids or foods. Breast milk covers the infant’s nutritional needs and provides protective antibodies.

Complementary feeding after 6 months

  • Around 6 months, infants require energy and micronutrients (iron, zinc, essential fatty acids) that milk alone no longer provides
  • Foods should be introduced gradually, adapted to chewing ability, and rich in energy and protein

Conclusion

Nutrition in pregnancy and lactation, and appropriate complementary feeding, are pillars of pediatric health. Personalized nutritional follow-up by a professional is recommended to meet individual needs.
