Pregnancy and breastfeeding nutrition
Pregnancy and breastfeeding are periods with specific nutritional needs — iodine, iron, folates, omega-3, vitamin D — where tailored support safeguards both maternal health and baby development.

Increased micronutrient needs
Some micronutrients become critical during pregnancy and breastfeeding. A varied diet covers most needs; some supplementation (folates before conception, vitamin D, sometimes iron) is prescribed by the doctor or midwife.
- Folates (B9): 400 µg/day from planning through week 12
- Iron: needs double — lean meats, legumes, paired with vitamin C
- Iodine: 200 µg/day (fish, dairy, iodised salt)
- DHA omega-3: 250 mg/day (oily fish twice a week, mercury excluded)
- Calcium and vitamin D: dairy, vitamin D supplement in winter
Weight loss after delivery
Sudden weight loss during breastfeeding can reduce milk supply and release pollutants stored in fat tissue. The goal is instead a gradual loss of 0.5 to 1 kg per month, while preserving the elevated energy and protein needs of lactation.
What belongs to your physician
Diagnosis, tests and medical treatment remain your doctor's responsibility. Dietetic support adapts to them and, with your agreement, a report is sent to your doctor.
Your first consultation, in practical terms
The initial assessment consultation (anamnesis) lasts 60 minutes, both within the CNS-covered pathway and as a private consultation. Here is what is useful to bring and what is covered.
Useful to bring
- Your pregnancy follow-up documents and recent lab tests (iron, ferritin, vitamin D, blood sugar).
- Supplements prescribed or taken on your own initiative, with their composition.
- Foods that have become difficult: nausea, aversions, reflux, new dislikes.
- Your medical prescription and social security card if CNS coverage is intended.
What is explored
- Coverage of the critical micronutrients: folate, iron, iodine, DHA, calcium and vitamin D.
- Everyday food safety: listeriosis, toxoplasmosis, high-mercury fish, alcohol.
- Digestive tolerance in the current trimester: nausea, reflux, constipation.
- While breastfeeding: energy needs, hydration and a gradual rate of weight loss.
What you may receive
- When a personalised eating plan is drawn up, it is adapted to the current trimester or to breastfeeding and presented during the 45-minute consultation dedicated to it.
- Concrete markers on which foods to avoid and what to replace them with without losing intake.
How progress is assessed
- Weight gain tracked against the pace indicated by your physician or midwife.
- Digestive tolerance and energy level from one consultation to the next.
- Lab tests remain prescribed and interpreted by your physician or midwife.
If the recommendations are hard to follow
Nausea, aversions and fatigue shift from one trimester to the next: the plan is meant to be revised, not endured. When a food no longer goes down, it is replaced by an equivalent source of the same nutrient, and coverage of needs is checked before adding any new instruction.
