Foods To Eat When Pregnant: First Trimester Diet

You need not have to eat for two during pregnancy. But you need to eat healthy and wholesome food to make sure you are gaining weight at the right rate and your baby is growing healthily. While your dietary requirements may be the same throughout pregnancy, you may want to know the various foods to eat during the first trimester, when you could be having morning sickness and nausea.

Here, MomJunction tells you about the foods you may include in your first-trimester diet.

Healthy Foods For Your First Trimester

You require all the essential vitamins and minerals from a varied diet in the first trimester. Folate, vitamin A, and beta-carotene are essential in the early stage of fetal development. So, here is the list of foods you can incorporate into your diet in the first trimester.

1. Spinach

Why it works: Spinach is rich in folate, which helps prevent neural tube defects such as spina bifida in the baby. Folate helps your baby’s neural tube to fuse correctly in the first month of conception (1). Spinach is also high in fiber, iron, vitamins A, C, E, and K, and manganese (2).

Tips to take it in your diet: You can add a handful of spinach in scrambled eggs, or combine it with any other vegetables in soups, stews, or curries. Eat it raw by adding it to smoothies or salads.

2. Lentils (pulses)

Why they work: They are a great source of protein and fiber that help in the development of the baby’s muscle and tissue (3). Fiber help in treating constipation, which is common in the first trimester. Make sure you stay hydrated when increasing your fiber intake.

Tips to take them in your diet: Lentil soup is a simple way to consume them. You can also add them to salads, ground meat, burgers, and more.

3. Citrus fruit

Why it works: Citrus fruits such as lemon, oranges, limes, kiwifruit, and grapefruit are rich in folic acid too, which is helpful in baby’s neural tube development (4).

Tips to take them in your diet: Eat oranges and grapefruits whole or make fresh juices. You can infuse water with citrus juice to stay hydrated. Try a simple citrus marinade on mushrooms or other proteins and roast, bake, or grill it.

4. Cottage cheese

Why it works: Cottage cheese provides calcium and protein needed for bone and muscle development of the baby (5).

Tips to take it in your diet: Top it with fruit, mix in smoothies, or spread it on bread or toast.

5. Nuts

Why they work: Nuts are an excellent source of protein and beneficial fats needed for the baby’s growth and development. Walnuts, almonds, cashews, and pistachios have a good amount of protein, healthy fats and fiber (6).

Tips to take them in your diet: You can have a few of them at any time of the day. Sprinkle them on any hot or cold cereal, yogurt or ice cream.

6. Eggs

Why they work: Eggs are an excellent source of protein, calcium, and vitamin D, all of which are essential for bone and muscle development in the baby. Choline present in egg yolk plays a vital role in fetal brain development (7). Soybeans are an alternative source for vegans.

Tips to take them in your diet: Have hard-boiled eggs, scrambled eggs, egg bakes, or omelet for breakfast. You can also add diced, boiled or sliced eggs to a salad or as a sandwich stuffing.

7. Yogurt:

Why it works: Yogurt is rich in calcium and vitamin D, which are required for bone development in the baby (8).

Tips to take it in your diet: Top plain unsweetened yogurt with it fresh, diced fruit or add to a smoothie. Mix with chocolate chips and freeze it for a sweet treat. Use it as a salad dressing.

8. Broccoli

Why it works: Rich in iron and folate, it is highly required for the formation of red blood cells and neural tube development (9).

Tips to take it in your diet: You can add it to salads, smoothies, and soups. For a different spin, you can also add to quinoa, grill on barbecue or eat raw.

9. Asparagus

Why it works: Asparagus is rich in folic acid that helps prevent birth defects of the fetal brain and spinal cord (10).

Tips to take it in your diet: Like spinach, it can be diced and tossed with scrambled eggs, added to salad, soups, omelet, pasta, and stir-fries. Drizzle it with oil and salt and grill.

10. Collard greens

Why it works: An excellent source of iron, which is essential during pregnancy for making red blood cells (11).

Tips to take it in your diet: Dice and add collard to salads, sandwich stuffing and wraps, or soups and casseroles. Blanch the leaves and use them as a “wrap” instead of the traditional wheat/flour based wraps.

11. Chicken

Why it works: Chicken contains iron, which helps in making red blood cells, thereby providing both the mom and baby with sufficient oxygen supply (12).

Tips to take it in your diet: Marinate and grill chicken and add it to casseroles, salads, sandwiches, soups and stews. Ground chicken works great in tacos or pasta sauces..

12. Salmon

Why it works: Salmon is rich in calcium and vitamin D (13).

Tips to take it in your diet: Do not consume raw or partially cooked seafood when pregnant. Season and grill a salmon filet and serve it with vegetables is classic. Top your salad or pasta for a protein punch.

13. Lean beef

Why it works: Beef is a rich source of iron which helps in the production of red blood cells, thus supplying enough oxygen to the mother and the baby (14). Grass-fed, hormone-free and organic are the best choices.

Tips to take it in your diet: Can be formed into burgers, loafs, or meatballs.  Use ground meat to add to salads, pizza and pasta. Toss with scrambled eggs and vegetables to make a lunch or dinner dish. Cook your ground beef to at least 160F/ 71C.

14. Bananas

Why it works: They are a rich source of vitamin B6 that helps curb morning sickness and nausea you experience during early pregnancy. They also contain fiber, potassium, and vitamin C (15).

Tips to take it in your diet: Eat it whole, slice it over yogurt, or freeze it and add to smoothies in place of ice.

15. Red bell peppers

Why it works: Vitamin C in red bell peppers is two times more than that in green bell peppers. The vitamin helps in iron absorption and is responsible for tissue growth and repair (16).

Tips to take them in your diet: You can add them to stir fries, sandwiches, burgers, salads. Casseroles and stuffed peppers with rice are other ideal options.

16. Avocados

Why they work: Avocados are nutrient-rich fruits with high levels of folate, fiber, protein, and antioxidants. They contain monosaturated fats that protect against heart ailments. They are also known to curb morning sickness and assist in the fetal brain and tissue development (17).

Tips to take them in your diet: Bake it along with egg, sandwich or toast filling, dip, salad dressing, and salsa.
