Evidence-based nutrition guidance for each trimester to support your health and your baby's development.
The Truth About "Eating for Two"
While you are growing a whole new human, you do not actually need to double your food intake. In the first trimester, no extra calories are needed. Second trimester requires only about 340 extra calories daily — roughly a yogurt and banana. Third trimester needs about 450 extra calories. Quality matters more than quantity.
Essential Nutrients for Pregnancy
Folate/Folic Acid
Critical for preventing neural tube defects. Find it in leafy greens, legumes, fortified cereals, and prenatal vitamins.
Iron
Your blood volume increases 50% during pregnancy. Sources include lean meats, spinach, beans, and fortified cereals. Pair with vitamin C for better absorption.
Calcium
Baby builds bones using your calcium stores. Dairy, fortified plant milks, leafy greens, and sardines are excellent sources.
DHA (Omega-3)
Supports baby's brain and eye development. Safe fish options include salmon, sardines, and trout. Limit to 2-3 servings weekly.
Protein
Aim for 75-100 grams daily from varied sources: lean meats, fish, eggs, dairy, legumes, nuts, and tofu.
Foods to Limit or Avoid
- Raw/undercooked meats and eggs
- High-mercury fish (shark, swordfish, king mackerel)
- Unpasteurized dairy and juices
- Deli meats (unless heated until steaming)
- Excessive caffeine (limit to 200mg daily)
- Alcohol — no safe amount during pregnancy
Nutrition by Trimester
Use our third trimester checklist to ensure you have meal prep completed before baby arrives. During nesting, stock your freezer with nutritious postpartum meals.
Managing Common Challenges
Nausea: Eat small, frequent meals. Ginger and vitamin B6 can help. Avoid empty stomach — especially important in early pregnancy when watching for signs of labor.
Heartburn: Eat smaller portions, avoid lying down after meals, limit spicy and acidic foods.
Constipation: Increase fiber, drink plenty of water, and stay active with prenatal yoga or walking.
Hydration
Aim for 10-12 cups of fluid daily. Water is best, but milk, 100% fruit juice, and herbal teas count too. Proper hydration is especially important for breastfeeding success.
Postpartum Nutrition
Good nutrition does not stop at delivery. During the fourth trimester, your body needs extra nourishment for recovery and milk production.
