Pregnancy Diet Plan: 1st Trimester to 3rd Trimester

Much of the preparation for pregnancy and birth is focused on avoiding risks, but did you know that the way you eat throughout your pregnancy can help to boost your baby’s IQ level, lower their future disease and obesity risk, and also make birth easier and less painful and help you to recover faster post-birth?

Why Should I Eat Well During Pregnancy?

An optimal nutritious diet throughout pregnancy is crucial for growing a healthy baby, minimizing complications, and also beyond birth. A healthy diet during pregnancy can reduce the chances of your baby developing obesity, diabetes, and heart disease later in life. Eating well and taking certain probiotics throughout pregnancy can dramatically reduce the chances of your baby developing asthma, eczema, and hay fever after they are born (more on this later).

This pregnancy diet plan gives you key foods to focus on for the baby’s development each month, along with common physical symptoms experienced at this time and nutritional and lifestyle strategies to manage these. First, let’s look at some general guidelines for healthy eating throughout your whole pregnancy.

What Should I Eat Throughout Pregnancy?



Focus on nutrient-dense whole foods: e.g. minimally processed food and as close to the natural form as possible. When you buying packaged foods – a good rule of thumb is if there are ingredients on the packet you don’t recognize – don’t buy it.

Good quality protein: most women during pregnancy require around 80 grams (2.8 oz.) of protein. Good quality proteins are minimally processed and they from high-quality sources e.g. grass-fed/free-range/organic where possible. To calculate your estimated protein requirement during pregnancy, times your pre-pregnancy weight by 1.2 – this is the amount in grams suggested to eat daily. (E.g. 65 kg woman requires ~78g protein per day).

Adequate healthy fats: modern research is demonstrating the importance of healthy fats for all body systems. During pregnancy, adequate fat intake is necessary for the development of the baby’s organs and brain. Healthy sources of fats include olive oil, nuts, avocado, and seeds, eggs, oily fish, meats.

An abundance of fresh vegetables and fruit: These are full of vitamins, minerals, and fiber. Eating varieties of fruit and veg will act as a cover-all in providing your body with many of the nutrients it needs, as well as plenty of fiber to avoid constipation. Eat plenty of leafy green vegetables (spinach, kale, collard greens, parsley, etc) for a good quality source of folate.

During pregnancy at least 10 cups of fluid, a day need to drink. As blood volume increases rapidly during pregnancy, enough amount of fluid is crucial for replenishing the baby’s amniotic fluid and can prevent morning sickness and constipation. Primarily, most of this fluid comes from water, herbal tea, and occasionally juices. And avoid soda/soft drinks, alcohol, and a high intake of tea and coffee.

Steer clear of processed/high sugar foods: processed foods offer very little nutrition and often contain chemicals that can be harmful to you and your baby. Don’t waste space with these types of low nutrient foods – crowd them out with nutritious, satisfying whole and you won’t feel deprived.

Moderate levels of grains/starch: when you eating grains, go for whole grains such as brown rice, whole oats, quinoa, or whole-grain pasta. Nutrient-dense starches include sweet potato, parsnip, pumpkin, and beetroot. The high amount of consumption of carbohydrates (particularly refined carbs and sugars) during pregnancy can imbalance blood sugar levels and contribute to gestational diabetes, so try to include moderate serves each meal.

High-quality pregnancy multivitamin that contains at least 400 mcg folic acid (to help prevent neural tube defects) – it is most important in the very early stages of pregnancy as the spinal cord is developed 4 weeks after conception. It is necessary to start as soon as you know you are pregnant, or ideally before you start trying to conceive. If you already know you have an MTHFR gene mutation (which is responsible for the conversion of folic acid to other compounds required by the body), you may also benefit from supplementing folinic acid and/or 5-MTHF instead.

Lactobacillus Rhamnosus probiotic: If both parents have a history of eczema, the risk of their baby developing eczema is around 60-80%. Probiotics containing Lactobacillus strains have been shown to reduce the risk of the child developing allergies by almost 80%. Lactobacillus rhamnosus when taken in the final trimester of pregnancy (and in some cases postnatally as well), it greatly reduces the risk of the baby developing atopy (asthma, eczema, hay fever). If you or your partner have a history of allergies, talk to your doctor about whether this probiotic might be helpful for you.

Magnesium: It is essential for fetal bone and teeth development and can prevent premature contraction of the uterus. It’s also a great supplement to take throughout your pregnancy as it helps muscles to relax, so it can help with constipation, assist your tissue growth and promote restful sleep.

Fish oil/omega 3’s are essential nutrients for neurological and visual development in your baby, and the production of breast milk. Healthcare experts say that supplementing with omega 3 during pregnancy can increase the cognitive development of your baby and boost future IQ. It is also found that a higher intake of omega 3’s may decrease the risk of allergy development in the baby. Furthermore, it has been shown to reduce premature labor, lower the risk of preeclampsia and the mother’s risk of depression. Consult with your doctor about whether an omega 3 supplement may be beneficial for you but more importantly note – the quality of these supplements varies widely. Choose good quality brands that have proven purity and appropriate storage – not the cheap brand off your chemist’s shelf. 

 1st Trimester Pregnancy Diet Plan – (4 – 13 weeks)

The beginning of 1st trimester of pregnancy is the first day of your last period. And this period continues until 12 weeks of your pregnancy which means the first 3 months of your pregnancy. In biological terms, this period is the first step of pregnancy. In that stage, the fertilized egg rapidly divides into layers of cells and implants in the wall of your womb. The interesting fact is these layers of cells become an embryo, the term we use for the baby in this stage.

Your fetal grows rapidly during the first trimester, and by the end of 3rd month, it grew a tiny human being that is a fetus. And during this fast-developing period, you need to have a disciplined diet.

    • hazelnuts
    • egg yolk

It is important to increase your intake of good-quality proteins like eggs and free-range meats (organic/grass-fed where possible). If you are vegetarian, ensure you are consuming enough iron-rich plant-based foods such as leafy greens and legumes with every meal, along with a source of vitamin C (such as a squeeze of lemon juice or some capsicum/peppers) as this enhances the body’s uptake of iron from plant-based sources. Iron deficiency during pregnancy causes fatigue for the mother and low birth weight in iron-deficient infants so keep on top of your iron intake or consult with your healthcare provider about supplementation of iron if this might be an issue or you have been feeling very fatigued.
  • High Fiber food: whole grains and green vegetables have high fiber content. Fiber-rich foods will help you get rid of constipation during the later stages of pregnancy.

Constipation is common around this time of pregnancy. Constipation commonly occurs during pregnancy as the body is slowing down the speed of digestion to ensure maximum uptake of nutrients to support the growth of your baby. Therefore, focussing on a nutrient-dense whole food, diet will likely prevent constipation as the body’s nutritional needs are being met.
