Healthy pregnancy nutrition: not “eating for two”
Nutrition during pregnancy should provide the energy, protein, vitamins, and minerals needed for maternal health and fetal growth. Pregnancy does not require doubling the amount of food. The focus is variety, safe preparation, and weight gain appropriate to your starting health.
What should you eat?
- A variety of well-washed fruit and vegetables;
- Protein from thoroughly cooked meat, poultry, eggs, lower-mercury fish, pulses, nuts, and seeds;
- Whole grains and fibre-rich carbohydrates;
- Pasteurised dairy or suitable alternatives for calcium and protein;
- Healthy fats such as olive oil, avocado, nuts, and seeds;
- Water regularly throughout the day.
Smaller, more frequent meals may be easier if nausea or heartburn is present.
Folic acid, iron, and other key nutrients
Folic acid is especially important before conception and in early pregnancy to reduce neural tube defect risk. Iron requirements rise as maternal blood volume increases. Iodine, calcium, vitamin D, choline, and omega-3 fatty acids are also important.
Take a prenatal vitamin according to professional advice. Combining supplements can result in excessive doses; “natural” does not automatically mean safe.
What should be avoided?
- Alcohol—no safe amount has been established during pregnancy;
- Raw or undercooked meat, seafood, fish, and eggs;
- Unpasteurised milk and products made from it;
- High-mercury large predatory fish;
- Unwashed produce and food stored or prepared unhygienically;
- Liver and high-dose vitamin A supplements unless specifically prescribed;
- Excess caffeine—commonly recommended total intake is no more than 200 mg daily.
Should fish be excluded?
No. Fish can be a useful source of protein and omega-3. Choose lower-mercury species and cook them thoroughly. Follow official local food-safety advice for locally caught fish.
Vegetarian and special diets
A well-planned vegetarian diet can be suitable, but protein, iron, vitamin B12, iodine, calcium, and omega-3 need particular attention. Seek individual advice for diabetes, coeliac disease, anaemia, hyperemesis, or significant weight concerns.
When should you contact a clinician?
Seek help if you cannot keep food or fluids down, are rapidly losing weight, have dehydration, severe weakness, fever, or diarrhoea after risky food exposure. Read more in Nausea and vomiting during pregnancy.
Pregnancy monitoring with Lana Ezieshvili
Healthy nutrition supports development, while ultrasound monitors growth against gestational age. Radiologist Lana Ezieshvili assesses fetal biometry, estimated weight, amniotic fluid, and the placenta.
For scheduled monitoring, book an appointment with Lana Ezieshvili. If you have gestational diabetes, anaemia, severe vomiting, or a weight concern, agree on nutrition with your obstetric clinician and an appropriately qualified dietitian.
