Pregnancy Nutrition: Complete Guide for Healthy Baby
Discover complete pregnancy nutrition with trimester-specific guidance, essential nutrients for baby development, safe foods vs foods to avoid, weight gain recommendations, and meal plans for a healthy pregnancy.
Understanding Pregnancy Nutrition Needs
Pregnancy nutrition is critical for baby's healthy development and mother's well-being. During pregnancy, nutrient needs dramatically increase - your body is building an entire human being! Key nutrients include folic acid (prevents neural tube defects), iron (supports increased blood volume and prevents anemia), calcium (builds baby's bones and teeth), protein (tissue growth), DHA omega-3 (brain and eye development), and vitamin D (bone health and immune function). Contrary to myth, you're not "eating for two" in terms of doubling calories - you need only 300-450 extra calories in 2nd and 3rd trimesters (equivalent to a yogurt and fruit). Quality matters far more than quantity. Proper pregnancy nutrition reduces risks of birth defects, preterm birth, low birth weight, gestational diabetes, and pre-eclampsia while supporting healthy weight gain, energy levels, and postpartum recovery.
Why Pregnancy Nutrition Matters
- • Prevents neural tube defects (folic acid)
- • Supports baby's brain and organ development
- • Reduces risk of preterm birth
- • Prevents maternal anemia and fatigue
- • Supports healthy birth weight
- • Aids postpartum recovery and breastfeeding
Healthy Pregnancy Weight Gain
- • Underweight (BMI <18.5): 28-40 lbs
- • Normal weight (BMI 18.5-24.9): 25-35 lbs
- • Overweight (BMI 25-29.9): 15-25 lbs
- • Obese (BMI ≥30): 11-20 lbs
- • Twins: Add 10-15 lbs to normal range
