Eating well
During pregnancy, it is important to make sure that your diet provides you with enough energy and nutrients for your baby to grow and develop. It is just as important to help keep you healthy and help your body to deal with all the changes taking place.
You are probably already wondering what you should and shouldn’t be eating now that you are pregnant. The good news is that there is not much to avoid and lots of things you enjoy already are good for you and your growing baby.
Healthy weight
Eating a healthy diet will provide your baby with all she needs to develop as well as helping you to keep in the best of health during your pregnancy. Your body makes various adjustments during pregnancy and so you do not need to ‘eat for two’. There are substantial risks to both you and your baby of too much weight gain in pregnancy including maternal diabetes and premature birth. If you are already over weight or obese when you become pregnant please speak to your midwife or GP for advice about weight gain. It is important not to ‘diet’ or try to lose weight while you are pregnant as this can harm both you and your baby. See the section on weight gain and body changes for more information.
Healthy drinks
It’s essential to keep your fluid levels up by drinking plenty of water and fruit juices. Often we think we are hungry when in fact what we actually need is water. Some experts suggest that the reason we retain water (and get puffy and bloated) is because we are not drinking enough of it. Drinking lots of water can also help with constipation.
It is important that fruit juice is consumed only along with meals to prevent tooth decay. See Oral Health in Pregnancy for more information.
Caffeine
If you are a regular coffee or tea drinker it’s a good idea to try and cut back. High levels of caffeine can affect your baby’s birthweight. For this reason it is important not to have more than 200mg of caffeine a day.
To give you an idea:
- an average cup of instant coffee has 75mg of caffeine
- regular brewed coffee has 100mg caffeine
- regular tea has 50mg caffeine.
Cola and some ‘energy drinks’ also contain caffeine:
- 40mg caffeine in a regular can of cola
- up to 80mg in some energy drinks.
You can substitute these with decaffeinated tea or coffee and look for drinks that are caffeine free, such as fruit juices.
As there isn’t a lot of information about the safety of herbal products, it is best to limit these while you’re pregnant. During pregnancy it is recommended that women drink herbal or green teas in moderation – around 4 cups a day. As little is known about the effects of Ginseng and Echinacea, it is best to avoid these when pregnant and breastfeeding. Speak to your midwife if you are unsure about using any herbal products.
Caffeine can also reduce iron absorption. Eating vitamin C rich food with a meal increases iron absorption.
What to eat
Eating a balanced and varied diet is the best way to be healthy and also help your baby to grow and develop. This means eating a range of things from the different food groups including:
- lots of fruit and vegetables
- plenty of starches like potatoes, pasta and wholegrain bread
- protein-rich food including at least two portions of fish and one portion of oily fish a week
- plenty of fibre which you’ll find in fruit and vegetables as well as rice and wholegrain bread; eating fibre-rich foods will help you deal with constipation
- dairy products like plain yoghurt, semi-skimmed milk and hard cheeses, which will help you get enough calcium.
If you feel sick there are various ways you can help to reduce your symptoms. You should take small, frequent healthy snacks and try to avoid large meals as these put a strain on your digestive system. You should not let your stomach remain empty for more than a couple of hours to keep your digestive system ticking over. A dry cracker or crisp bread may help. It is a good idea to keep these by your bed to snack on before you get up in the morning.
