Can You Go Vegetarian During Pregnancy or Breastfeeding? A Careful Transition Guide
Vegetarianism isn't off-limits during pregnancy or breastfeeding, but this isn't the time to overhaul your diet on your own.
The Basic Principle
Mainstream nutritional science holds that a well-planned vegetarian diet—especially an ovo-lacto vegetarian one—can meet nutritional needs during pregnancy and breastfeeding. But “well-planned” is the key phrase: this is not the time to experiment with major dietary changes on your own.
Nutrients That Deserve Extra Attention
- Iron: needs rise significantly during pregnancy, and plant-based sources are absorbed less efficiently, so this often requires extra attention
- Vitamin B12: directly affects fetal neurological development; anyone eating vegan must supplement it regularly
- Protein and calories: total needs rise during pregnancy and breastfeeding, so it's not enough to simply “eat less meat”
- DHA: plant-based sources are limited, and doctors may recommend an algae-oil supplement
Recommended Approach
If you want to start or adjust a vegetarian diet during pregnancy or breastfeeding, be sure to consult an obstetrician or clinical dietitian in advance for an individualized assessment, rather than relying on generic advice found online.
A Word for Expectant Mothers
If you're already eating vegetarian and in good health, there's no need to panic and overhaul your diet just because you're pregnant—but any major change is worth confirming with a professional first. During prenatal checkups, it's worth proactively telling your doctor about your eating habits, so they can combine that with your blood test results to give you more precise nutritional advice. That's far more reliable than researching it yourself online.
