Pregnancy is an exciting time, but the first trimester is not always the glowing experience people expect. If you thought you would be blooming and instead you have your head over the sink, you are not alone. Nausea and food aversions are incredibly common in early pregnancy, and eating anything at all can feel like a challenge.
It would be lovely to eat a perfectly balanced diet the whole way through, but most women will tell you that is unrealistic in the first trimester. The goal during these weeks is simply to eat what you can keep down, stay hydrated, and cover a few key nutrients. Below, our Accredited Practising Dietitians share gentle, practical ideas to help you through.
Written by the Accredited Practising Dietitians at Body Fusion, who support women through every stage of pregnancy.
In early pregnancy, rising hormones (including hCG and progesterone) slow digestion and can leave you feeling nauseous, bloated or off your food. Progesterone relaxes the muscles of the digestive tract, which can also contribute to reflux and constipation. For most women this eases from around 12 to 14 weeks, though everyone is different and some feel it for longer.
When nausea hits, plain, dry and mildly salty foods are often easiest to tolerate. There is no single right answer, so keep a few options on hand and go with what appeals on the day.
An empty stomach can make nausea worse, so try to eat something small before you even get out of bed. Keep plain crackers or dry cereal on your bedside table and have a few bites before you sit up. From there, aim for small amounts every two to three hours rather than three large meals.
Large or rich meals can sit heavily when digestion has slowed. Small, bland, regular snacks are usually easier to manage and help steady your blood sugar and your stomach through the day.
Protein and iron are important for your baby’s development, but some women find heavier proteins like steak or lamb harder to stomach early on. If that is you, eat protein at the time of day you feel best, and choose gentler options such as minced meat, chicken, eggs, fish (see the safety note below), tofu, legumes, dairy or a smoothie with milk or yoghurt.
Greasy, fried or very strong-smelling foods can trigger nausea for some women, so limit these if they bother you. If bloating is an issue, you may also find large amounts of certain high-fibre or gas-forming vegetables (such as cabbage, cauliflower, broccoli or onion) less comfortable. This is very individual, so only cut back on the foods that actually affect you, and keep including the ones you tolerate well.
Dehydration can make nausea worse, so sip fluids often rather than drinking a large glass at once. Cold or icy water, weak tea, milk, or diluted juice can all help. Some women tolerate fluids better between meals than with them. If plain water is unappealing, try adding a slice of lemon or a little ginger.
Cravings and aversions can change day to day, so keep a variety of easy foods available and do not worry if what worked yesterday does not appeal today. Eating something is better than eating nothing during these weeks.
A pregnancy multivitamin helps cover key nutrients when your eating is limited. Folate (folic acid) is especially important in early pregnancy to support your baby’s neural tube development, and iron supports the extra blood volume you are building. If iron tablets worsen nausea or constipation, talk to your GP or pharmacist about the timing, dose or form that suits you best. Take supplements at the time of day you feel most settled.

Separate from nausea, there are a few foods best limited or avoided in pregnancy for food-safety reasons, because of the risk of listeria and other bacteria, or high mercury or excess vitamin A. As a general guide these include:
For the full, current list and safe-handling advice, follow official Australian food safety guidance, and check with your GP, midwife or dietitian if you are unsure about a particular food.
Some nausea and vomiting is normal, but if you cannot keep any food or fluids down, are losing weight, feel dizzy or are passing very little urine, contact your GP or midwife promptly, as this can be a sign of severe morning sickness (hyperemesis gravidarum) that needs medical care. If you are finding it hard to eat enough or manage a health condition through pregnancy, an Accredited Practising Dietitian can help you build a realistic plan around how you are feeling.
Every pregnancy is different, and what you can eat will change week to week. Our women’s health dietitians can help you meet your nutrition needs when nausea, aversions or a health condition make it hard, without adding pressure or guilt. It is one of the many areas we support through our women’s health nutrition service.
Plain, dry, mildly salty foods like toast, crackers, rice cakes and dry cereal are often easiest to tolerate, along with cold foods that smell less strongly and ginger in drinks or food. Eating small amounts regularly, and having something before you get out of bed, tends to help more than any single food.
During these weeks the priority is simply eating what you can keep down and staying hydrated, rather than a perfect diet. Small, frequent snacks, gentle fluids and a pregnancy supplement help cover the gaps. Your appetite usually improves as nausea settles, often from around 12 to 14 weeks.
For food-safety reasons, it is generally advised to avoid raw or undercooked meat, chicken, eggs and seafood, cold deli meats and soft cheeses unless cooked, unpasteurised dairy, pre-packaged salads and pate, high-mercury fish, liver, and alcohol, and to limit caffeine. Always check current official food safety guidance, as recommendations are updated over time.
Folate (folic acid) is important in the weeks around conception and early pregnancy to support your baby’s neural tube development, which is why it is included in pregnancy supplements. For the recommended amount and how long to take it, follow current Australian guidance and speak with your GP, pharmacist or dietitian.
For many women, nausea eases from around 12 to 14 weeks, but this varies and some experience it for longer. If you cannot keep food or fluids down at any stage, speak with your GP or midwife.
