First Trimester
Foundation Building (Weeks 1-12)
The first trimester is a critical period of fetal development. Your baby's neural tube, heart, and major organs begin forming, making adequate nutrition essential from the very start. While you may not need many extra calories yet, the quality of nutrients is paramount.
Key Nutrients
- Folate (600-800 mcg/day): Critical for neural tube development and preventing birth defects
- Iron (27 mg/day): Supports increased blood volume and prevents anemia
- B12: Works with folate for healthy fetal development
- Protein: Essential for tissue growth and development
Common Challenges
- Morning sickness and food aversions
- Fatigue and decreased appetite
- Nausea management strategies
- Food safety considerations
