What to Eat During Third Trimester of Pregnancy

A mother knows that a proper diet is best for pregnancy. A baby is dependent on his mother for nutrients and it is up to a mother to eat a healthy diet.  His brain, bones, organs, lungs, and eyes are at a developing stage and they have extra nutritional needs. There are so many food items and it becomes difficult to choose any. Some vital items to be eaten during the pregnancy are as follows:

  • Protein-rich food- A baby requires proteins for the development of tissues and muscles. Most protein-rich food has high contents of zinc and iron that helps in preventing preterm delivery and low-birth weight. Such items are beef, turkey, green salads, pork, chicken and beans
  • Eggs- These are very healthy as they aid in cell functions, memory development, and overall growth. Eggs can be eaten as omelets, boiled or scrambled
  • Salmon- Salmon is very healthy as it is rich in Omega-3. It will help in the development of the brain and nervous system.
  • Nuts- This is a good option for snacks and they contain protein, fiber, and fats
  • Fruits- Fresh fruits are always healthy for mother and her baby. Doctors advise against eating papaya and pineapple during pregnancy and besides them, a mother can eat any fruit she desires
  • Fresh vegetables- This is best for a baby especially green ones as they provide necessary nutrients.

Third Trimester of Pregnancy Ultrasound

During a third trimester, a doctor may advise an ultrasound. This scan shows the baby’s heartbeat and heart rate. It also helps in measuring his height so that a doctor can know the rate at which growth is occurring.

At the start of the third trimester, a scan shows a baby with different facial expressions and the baby’s arms and legs. By the end of the third trimester, he looks exactly the same as he would after birth. A scan at this time also shows exact birth position of a baby.

Hi, I’m Stephanie. I graduated college with a business degree and a minor in biology. I met my husband at a business convention and was happily marriage and pregnant within the first two years after saying the words “ I do”.

Jennifer is the eldest of the three. Being pregnant with her, my first, I researched everything pregnancy related and read nearly every book. Giving birth to Anthony and Matty seemed more natural and less stressful the third time around.

I’m happy to share what knowledge I have gathered and learn new things from other mothers. From morning sickness to Anencephaly, or potty training to thumb sucking, I have books and resource guides to share.
