Foods to Eat When Pregnant according to Principal Dietitian, Wong Hui Xin

In this chapter of the ‘Ask the Expert’ series, a principal dietitian, Wong Hui Xin gives us some pregnancy diet tips for proper nutrition.

When you’re pregnant, the food you eat is most important, especially because it will support the healthy growth and development of your baby. Your pregnancy diet can also minimize health risks, and help you achieve appropriate weight gain for you and your baby.

To help expectant mothers navigate their dietary needs, Principal Dietitian Wong Hui Xin shares expert advice on common pregnancy nutrition concerns. See this thread for more information.


Q: What foods should I eat during pregnancy?

Hui Xin: Mummy will need to follow a healthy balanced diet throughout the pregnancy. Include:

  • Wholegrains
  • Protein foods like fish/chicken/lean meat, eggs, beans, and legumes 
  • Fruits and vegetables

High-protein snacks like toast with peanut butter, soybean curd, and yogurt with muesli are helpful to boost protein and calorie intake.


Q: What makes up a healthy meal for pregnant women? Any snack ideas?

Hui Xin: A healthy balanced diet should include carbohydrates, proteins, fruits, and vegetables or the 4 food groups. Follow the portions as stated in my “My Healthy Plate.”

For snacks, try:

  • Nuts
  • Yogurt
  • Toast with peanut butter

Q: Are there foods I should avoid during pregnancy?

Hui Xin: Yes, avoid:

  • Raw foods (e.g., sushi or undercooked meats)
  • Alcohol
  • High-mercury fish (e.g., shark, swordfish)

Limit caffeine to 200mg per day—about one cup of brewed coffee or two cups of instant coffee.


Q: Can I eat junk foods during pregnancy?

Hui Xin: Junk foods like fries and chips are not healthy. They provide you calories without much nutrients that your body needs. You and your baby need adequate nutrition to ensure optimal health.


Q: Can I eat spicy foods during pregnancy?

Hui Xin: Yes, as long as you can tolerate them.


Q: How can I gain weight in my first trimester despite nausea?

Hui Xin: Eat small, frequent meals and focus on eating your largest meal when nausea is minimal. Adding 1–2 servings of maternal milk daily can also help boost calorie intake.


Q: I’ve lost my appetite in the first trimester and feel repulsed by chicken and green vegetables. I’m also allergic to eggs. How can I get enough protein on a vegetarian diet?

Hui Xin: You may try plant protein sources like tofu, taukua, soy milk, beans, and legumes. If possible, consider including fish or lean meat.

During pregnancy, you’ll need about 1 gram of protein per kilogram of your weight, plus an additional 9 grams. For example, a 50kg person needs about 59g of protein daily.


Q: I’m in my second trimester but haven’t gained much weight or regained my appetite. How can I ensure my baby gets enough nutrients?

Hui Xin: Eat small, frequent meals and add calorie-dense foods like:

  • Healthy fats in cooking
  • Thicker spreads (e.g., peanut butter) on toast
  • Higher-energy maternal milk

Q: Should I focus on calories or nutritious food during pregnancy?

Hui Xin: Both are important. Aim to consume enough calories to support weight gain while prioritizing nutritious foods.


Q: What nutrients are most important in the third trimester?

Hui Xin: Your calorie needs increase by 480kcal daily in the third trimester. Stick to a balanced diet, increase portions slightly, and include 1–2 extra snacks per day.


Q: Should I take supplements during pregnancy? What are the best ones?
