Good nutrition during pregnancy supports your health and your baby's development. Here's what to eat—and what to avoid—for a healthy pregnancy.
Calories Don't Double
"Eating for two" doesn't mean doubling your intake. Most pregnant women only need about 300 extra calories daily during the second and third trimesters. Quality matters more than quantity. Focus on nutrient-dense foods rather than empty calories.
Weight gain during pregnancy varies based on pre-pregnancy BMI, but most women should gain 25-35 pounds. Your healthcare provider can guide you on appropriate weight gain goals. Slow, steady weight gain is healthier than rapid gains or restrictions.
Key Nutrients
Folic acid prevents neural tube defects—aim for 400-800 mcg daily from supplements and foods. Iron supports increased blood volume; pregnant women need nearly double the iron of non-pregnant women. Calcium builds baby's bones and teeth while protecting yours. Omega-3 fatty acids support brain and eye development.
Other important nutrients include vitamin D, iodine, and choline. A quality prenatal vitamin helps fill gaps, but shouldn't replace a healthy diet. Whole foods provide nutrients in forms your body can use better than supplements alone.
What to Eat
Focus on variety: lean proteins, whole grains, colorful fruits and vegetables, and healthy fats. Protein is crucial for baby's growth—aim for 75-100 grams daily. Include iron-rich foods like lean meats, beans, and fortified cereals, paired with vitamin C to enhance absorption.
Stay hydrated—aim for 8-10 glasses of water daily. Limit caffeine to 200mg (about one 12oz coffee) and avoid herbal teas unless approved by your provider.
Foods to Avoid
Certain foods pose risks during pregnancy. Raw or undercooked meat, eggs, and seafood can harbor harmful bacteria. Unpasteurized dairy and juices may contain listeria. High-mercury fish (shark, swordfish, king mackerel, tilefish) can damage baby's nervous system.
Deli meats and hot dogs should be heated to steaming before eating due to listeria risk. Avoid raw sprouts, which can harbor bacteria. No amount of alcohol is proven safe during pregnancy—skip it entirely.
Managing Common Issues
Morning sickness may make eating difficult. Focus on small, frequent meals. Cold foods like yogurt, smoothies, and sandwiches are often better tolerated than hot meals. Ginger and vitamin B6 can help.
Heartburn is common in later pregnancy. Eat smaller meals, avoid lying down after eating, and limit spicy or acidic foods. Constipation responds well to fiber, water, and physical activity.
