Healthy eating tips

Now you're pregnant, people may tell you to have second helpings or to eat more treats '...because you're eating for two'. It’s not true and is likely to lead to extra weight gain.

You may be surprised to hear that you don't need any extra calories for the first six months of your pregnancy, unless you were underweight to start with.

In the last three months, you may need around 200 extra calories a day, which isn't very much - around two slices of wholemeal toast and butter.

Not all calories are equal, though. If you choose healthy options, such as plain, low-fat yoghurt with banana, it will provide you with around 200 calories of food containing nutrients for you and your baby. However, 200 calories worth of crisps (40g bag) will give very few nutrients.

When such a small amount of food can add so many calories, it's important to keep an eye on the amount of food on your plate. Family and friends might offer you large portions, but it is important to eat in moderation, eat regularly and avoid skipping meals.

What is a balanced diet in pregnancy?

Everything you eat and drink reaches your baby in some way and influences their health, so you need a good range of healthy foods. Having a balanced diet means making sure you include foods from the four main food groups, which will give you and your baby the nutrients you need.

The Eatwell plate shows the main food groups and your diet should have most foods from the biggest groups, medium portions from the middle size groups and only a very small amount from the smallest group.

The main food groups are:

  • Fruits and vegetables - aim for five portions a day and choose a variety from fresh, frozen, canned (without sugar or salt) dried and pure fruit juice (choose only one portion of juice daily).
  • Starchy carbohydrate foods, such as bread, potatoes, rice and pasta and low sugar breakfast cereals (wholegrain versions are best) - try to have these at every meal.
  • Foods that are high in protein, such as meat, fish, eggs and pulses (beans, peas and lentils) - aim to eat these twice a day.
  • Dairy foods, such as milk, cheese and yoghurt - aim to have three portions a day – lower-fat versions have the same amount of calcium as regular.                          
  • There is a fifth group, which consists of fatty, sugary foods such as spreads and cooking fats, biscuits, sweets, cakes, crisps and fizzy drinks. Try not to have them too often, and if you do choose them, have small portions.

Eating to keep your blood sugar levels stable in pregnancy

It's important to eat regular meals and snacks if you can. This will help keep your blood sugar levels stable.  It is also wise to choose foods that release their energy slowly, rather than foods that convert quickly to sugar in the blood. This may help you feel fuller for longer. It should help control your appetite and may be useful if you’re trying to manage your weight.

Foods that release their energy slowly include:

  • wholemeal bread, such as multigrain or granary
  • basmati rice
  • boiled potatoes, including the skin
  • broccoli, cauliflower, carrots and sweet potatoes
  • foods made from oats – porridge, oatcakes and oatbreads
  • Peas, beans and lentils
  • Plums, peaches and apples

Avoid foods that release their energy quickly, such as:

  • sugar and sugary foods
  • sugary soft drinks
  • white bread
  • white rice

Start right with breakfast now you're pregnant

Lots of people skip breakfast because they think they don’t have time for it, but studies have shown that women who have breakfast are more likely to be able to control their weight than those who don’t.

Your body has been fasting while you've been asleep and if you don’t eat in the morning you'll feel tired and hungry and be more likely to overeat later.

If you’re not used to having breakfast, have a look at these 5 easy breakfast ideas.

If you feel too sick to eat first thing in the morning, or you’re really pushed for time, try making a packed breakfast the night before to take to work.

Be smart with food shopping during pregnancy

Whatever you do, don't go shopping when you're hungry. Instead, go to the shops after you've had a meal or snack. If you're in the supermarket and you haven't eaten, you're more likely to reach for biscuits, chocolate or crisps. If you have them in the cupboard at home, they can be an easy, quick option so avoid temptation and don't put them in your shopping trolley in the first place.

Try to plan your meals and go shopping with a list. If you shop online rather than going to the supermarket you may be less likely to be tempted by junk food.

Healthy eating when you have morning sickness

Listen to your body and eat when you can manage it. Pregnancy sickness, or morning sickness, doesn't last forever.  There is no scientific evidence to back any of the following suggestions but they have helped some women so you could try them:

  • eating a little as soon as you wake up, before getting out of bed
  • eating ginger or foods containing ginger
  • not eating and drinking at the same time
  • getting more rest
