What to eat in your third trimester?

Maintaining healthy nutrition during your final stretch of pregnancy is important for your growing baby—and your ever-changing body! To cross the finish line feeling strong, follow these tips.

You may gain around 400 grams per week this trimesteri. As you and the baby get bigger, it’s important to continue eating sufficiently and healthily. Try to eat 3 small to moderate-sized meals at regular intervals, and 2-3 nutritious light snacks spread throughout the day. Continue to aim for a healthy diet, including a variety of vegetables and fruits, protein-rich foods which include milk, beans, whole grains and nuts, to ensure your baby gets a balanced nutrient intake crucial for his or her overall development.

Don’t forget your nutrients, including calcium, protein, iron and DHA

Don’t forget your nutrients, including calcium, protein, iron and DHA

Your baby’s need for calcium is especially great in this last trimester, where most of his or her bone development occurs. Continue to consume dairy products like low fat milk and yoghurt, as they are rich in calcium and also magnesium and phosphorus important for bone development. Try to have sufficient vitamin D from sun exposure or your diet as it helps in calcium absorption.

His or her growing muscles and tissues also need proteins. During the third trimester of your pregnancy, you need extra protein of around 30 grams dailyii which you can get from a variety of sources such as poultry, fish, milk, and eggs. Poultry and red meat are not only a good source of protein, they are also rich in zinc which supports both your and your baby’s immune function.iii Also continue to include iron-rich foods like spinach, poultry and red meat in your daily meals to help your little one with his or her red blood cell production.

DHA remains very important for baby’s brain development, so make sure your diet includes fatty fish, a great source of this brain-boosting nutrient. As a building block of your baby’s brain, DHA accumulates most rapidly in his or her brain during this last trimester until the first year of life.iv Continue to consume around 200 milligrams of DHA dailyv

Healthy diet for 3rd Trimester

Remember to also take your supplements which may include iron, folic acid and calcium as directed by your doctor.

Eating well now can also help your body recover and repair itself after you give birth. So fill your plate with lean meats, legumes, soybeans, fish, fruits and vegetables, milk, as well as other healthy foods. These nutrients will also help you produce the breast milk your baby needs after birth.

If you have nutrition questions, be sure to speak with your doctor for expert help in creating a pregnancy diet tailored to your personal third trimester needs.

Drink plenty of water

Drink plenty of water!

It may feel like you're spending your life in the restroom these days. At this stage of the pregnancy, your baby is large enough to be pressing rather steadily on your bladder, making those trips to the bathroom much more urgent, no matter the time of day (or night!) But that doesn't make proper hydration any less important. You would need at least 300ml of additional fluid intake.vi Adequate hydration is especially important during pregnancy to support amniotic fluid and the increase in blood volume.vii It can even help alleviate constipation and may also keep the leg cramps in check.

Maintain your exercise routine

Maintain your exercise routine

Even a little exercise during pregnancy can help you stay fit for birth and beyond, as well as helping to prepare your body for labor and delivery. So don't give up now, even if getting physical is the last thing you want to be doing. Do what you can, and what your doctor says is OK.
