As well as your free vitamins, you could be eligible for a Best Start Foods payment card to help you buy some food basics, including milk and fruit and vegetables.
More about Best Start Foods
Dieting to lose weight in pregnancy isn't recommended, even if you're overweight to begin with.
Some weight gain in pregnancy is normal and includes the weight of your baby, the placenta and amniotic fluid.
Some foods taste different as your sense of taste can change when you’re pregnant. This is caused by hormonal changes in your body.
You might find you can’t eat foods you used to enjoy or crave them if they start to taste better. If you're craving high-fat or high-sugar foods, try to limit them and eat regular balanced meals and healthy snacks instead.
Food to avoid
To reduce the chance of harming yourself or your baby, you should avoid certain foods.
You should avoid eating:
- unpasteurised semi-hard and soft cheeses (unless cooked until steaming hot)
- all mould-ripened soft cheeses with a white coating on the outside, such as brie, camembert and chèvre (unless cooked until steaming hot)
- soft blue cheeses such as Danish Blue, Gorgonzola and Roquefort (unless cooked until steaming hot)
- any unpasteurised cow’s, goat’s or sheep’s milk or cream
Liver and pâté
Liver and liver products such as pâté or liver sausage can have large amounts of vitamin A. This can be harmful for your baby. All types of pâté, including vegetable versions, can have listeria in them. It’s best to avoid them.
Do not eat swordfish, marlin, shark or raw shellfish.
Do not eat smoked fish products, including smoked salmon and smoked trout, unless thoroughly cooked as they can present a risk of Listeria. This includes in sushi.
You should not eat game meat, such as hare, partridge or pheasant due to the presence of lead. You should also not eat raw or rare meat as this can cause food poisoning.
Always make sure any meat you eat is well cooked and steaming hot all the way through. You should not be able to see any pink meat and the juices should run clear.
Too much oily fish or tuna
Try not to have more than two portions of oily fish a week. Oily fish includes mackerel, sardines and trout.
Tuna is not classed as an oily fish, but do not eat more than two tuna steaks (about 140g cooked or 170g when raw) or four medium-size cans of tuna (about 140g when drained) per week.
These need to be cooked well until they are hot throughout to make sure they do not make you ill.
Unwashed fruit and vegetables
Be careful with fruits, vegetables and salads as they can have soil on them, which can make you unwell. Make sure to thoroughly wash all fruits, vegetables and salad ingredients.
During pregnancy it's safe to eat:
- cooked fish
- sushi, but only if the fish has been cooked thoroughly
- seafood/shellfish as long as it has been cooked, for example mussels, lobster, crab, oysters, scallops, clams and cold, pre-cooked prawns
- Peanuts and other nuts (unless you're allergic) - eating nuts when pregnant will not affect whether or not your baby has a peanut allergy
- spicy food - there's no reason to avoid spicy foods
- honey - it's ok for you to eat honey, but you should not give it to your baby until they're over a year old
You're safe to eat some milk and dairy foods, including:
- All hard cheeses, such as cheddar, Parmesan or Gruyere
- Pasteurised semi-hard and soft cheeses, such as cottage cheese, mozzarella, feta, paneer, ricotta, halloumi, cream cheese, cheese spreads, or goat's cheese without a white coating on the outside (rind)
- Any cheese that has been thoroughly cooked until steaming hot
- Pasteurised milk and yoghurt
Cream and ice cream are safe, but are not considered 'dairy' by The Eatwell Guide and have high sugar and fat content.
You can eat runny or even raw eggs as long as they are pasteurised, or have the British Lion Code mark on them, or are Laid in Britain (LIB) eggs.
Foods made with these eggs are also safe to eat. This includes:
- ice cream
- salad dressing
Make sure that duck, goose and quail eggs are thoroughly cooked.
If you’re eating out and not sure if they use British Lion Code or Laid in Britain eggs, ask the staff to find out for you.
Aim to have 6 to 8 200ml glasses of water or other fluids every day, and:
- try different kinds of drinks, such as sugar-free squash, decaf tea and coffee, fizzy water, fruit juice or smoothies
- limit fruit juice or smoothies to 150 ml per day with meals to help to prevent damage to your teeth
Decaffeinated coffee and tea are safe to drink during pregnancy.
Do not drink alcohol during pregnancy.
Drink plenty of water when you’re pregnant to keep hydrated and stop you getting constipated, especially in your last 3 months.
You should boil water before you drink it if you get your drinking water from a private supply, such as a well, borehole or spring. The quality of water from private supplies can vary a lot and when it’s poor it can cause health problems.
During pregnancy you should:
- have no more than 4 cups of herbal or green tea a day as there isn't enough evidence about their effect on developing babies
- avoid teas that contain ginseng or echinacea as doctors aren’t sure what effects they might have when you’re pregnant or breastfeeding
Talk to your midwife if you’re unsure about using any herbal products.
Caffeine's found naturally in chocolate, coffee and tea (including green tea). It’s also added to some:
- soft drinks
- energy drinks
- cold and flu remedies
Having too much caffeine when you’re pregnant can:
- increase your risk of miscarriage
- affect how your baby grows
- cause your baby to be small and underweight - this can lead to health problems later in life
If you have too much caffeine, your baby can start to withdraw from it when they're born. This makes them irritable.
How much caffeine's safe?
While you’re pregnant it’s important to have no more than 200mg of caffeine a day.
