Nutrition During Pregnancy and Breastfeeding
Pregnancy and breastfeeding significantly increase your nutritional needs. Your body requires additional calories, protein, vitamins, and minerals to support your baby's growth and development while maintaining your own health. Understanding these increased needs helps ensure optimal outcomes for both mother and baby.

|---|---|---|---|
| First | 1-12 | 0 (focus on quality) | Folate, iron, prenatal vitamins |
| Second | 13-27 | +340 per day | Protein, calcium, healthy fats |
| Third | 28-40 | +450 per day | Iron, protein, omega-3s |
Breastfeeding Nutrition Needs
- Exclusive Breastfeeding: +500 calories per day
- Partial Breastfeeding: +300 calories per day
- Additional Protein: +25g per day
- Hydration: Minimum 3.8L total fluids daily

Breastfeeding and Weight Loss
Breastfeeding burns approximately 300-500 calories per day. While this can support gradual weight loss, rapid weight loss (more than 0.5 kg/week) should be avoided as it can affect milk supply and quality. Focus on nutrient-dense foods and avoid restrictive dieting while breastfeeding.
Foods to Limit or Avoid
During Pregnancy
- Alcohol: Completely avoid
- High-mercury fish: Shark, swordfish, king mackerel, tilefish
- Raw/undercooked foods: Sushi, raw eggs, undercooked meat
- Caffeine: Limit to 200mg per day (about 1 cup coffee)
- Soft cheeses: Unpasteurized cheeses like brie, camembert
During Breastfeeding
- Alcohol: Limit and time carefully around feeding
- Caffeine: Moderate intake (1-2 cups coffee daily)
- Allergenic foods: Only avoid if baby shows sensitivity
