Pregnancy Diet Plan for Each Trimester

Updated on 24 November 2025

Pregnancy is a life-altering experience that, though wonderful, brings with it a feeling of acceptance of responsibility. One essential part of a healthy pregnancy is nutrition. The food you eat plays a role in your baby's development and your overall well-being. Your nutritional needs will change as you change and your baby grows. So, it is essential that you have a pregnancy diet for each trimester.

Why is diet important during pregnancy?

A healthy diet during pregnancy can help you:

Fetal development
Help the placenta and tissues grow
Amniotic fluid will be sufficient
Maternal overall health
Less risk of birth defects and complications

Key nutrients during pregnancy, such as folic acid, iron, calcium, protein, DHA, and vitamins, play an important role in supporting fetal organ formation, brain development, and the immune system.

First Trimester Pregnancy Nutrition Guide (Weeks 1–12)

In the first trimester, the baby's brain, spinal cord, and major organs begin to develop. Many women also have morning sickness and food associations during this period.

Necessary Nutrients Required:

Folic Acid: Reduces the risk of neural tube defects.
Vitamin B6: It might help with nausea.
Iron: Helps the amount of blood in the body develop.
Protein: Helps tissues grow.

How to Consume:

If you can manage it, attempt to eat small amounts more often.
Eat a lot of leafy greens, citrus fruits, legumes, and cereals that have been fortified.
Drink a lot of water.
If you're not feeling well, eat foods that are bland and easy to digest.

Pregnancy Nutrition in the Second Trimester (Weeks 13–26)

The baby grows swiftly during the second trimester. Its bones are stronger, its muscles get bigger, and its nervous system gets stronger. You might feel less sick and more hungry.

Necessary Nutrients:

Vitamin D and calcium are good for your bones.
Fatty acids like omega-3 help the brain and eyes grow.
Iron and vitamin C to stop anaemia from occurring and to help the body use the iron it gets.
Fibre helps you not get constipated.

Nutrition Tips:

Eat a variety of foods, such as whole grains, dairy, tofu, almonds, salmon, and eggs.
Keep eating fruits and vegetables that are vibrant in colour.
You should eat roughly 60 to 70 more grams of protein every day.
To stay hydrated, drink a lot of water.

Diet During Pregnancy While in the Third Trimester (Weeks 27–40)

During the third and last trimester, the baby grows quickly, and the brain, lungs, and other organs are getting stronger. The mother may also start to have indigestion, problems digesting, or oedema.

Key Nutrients Required:

Protein to make tissues and organs grow.
Iron to assist in keeping babies from being too tiny or being born too early.
Vitamin K is very crucial for helping your blood coagulate!
Healthy lipids are important for brain growth.

Dietary Recommendations:

It's better for your digestion to eat smaller meals more often.
Try to consume lean protein, whole carbohydrates, and lots of green leafy vegetables.
To avoid bloating, don't eat foods that are high in sodium.
Instead, eat healthy fats like nuts, olives, and avocados.
