What should you eat and avoid in pregnancy?

Face it: In pregnancy, you need only an extra 100 to 300 calories each day to grow a healthy baby. That’s as simple as a sliced apple with peanut butter or low-fat yogurt with fresh fruit. Use the latest research and our suggestions for healthy eating by trimester:

1st Trimester 2nd Trimester 3rd Trimester
Morning Sickness Relief
Morning sickness can be miserable. And a review of the latest research shows that all of the common remedies—from ginger tea to vitamin B6—failed for most to cure nausea and vomiting during the first weeks of pregnancy. Combat any loss in nutrition with daily prenatal vitamins. Start the day by munching on a few saltine crackers before rising, and wait until after breakfast before brushing your teeth.
Emphasize Healthy Eating
What’s great nutrition for all Americans also works for you and your baby. New dietary guidelines recommend filling half of your plate with fruits and veggies at every meal or snack. Not only will you get the essential vitamins, nutrients and fiber your body craves in pregnancy, you’ll have more energy.
Ramping Up for Birth
The latest headlines are exploring a link between eating more fish and reducing early birth risks—including preterm birth. Experts recommend 8-12 ounces a week of low-mercury fish—or about 2 meals—a week. In research, women who ate fish up to three times weekly reduced their preterm birth risks. Choose safer fishes high in omega 3 fatty acids, like wild caught salmon.
