What are carbohydrates?
Carbohydrates are the main source of energy in your diet. They are broken down into simple sugars like glucose, which pass easily across the placenta and provide energy to support your growing baby during pregnancy.
The different types of carbohydrates include starches, sugars and fibre. For a steady supply of energy, starchy foods such as bread, potatoes, pasta, rice and cereal should make up about a third of the food you eat. Many starchy foods also provide other important nutrients for your baby’s development, including calcium, iron and B vitamins.
Choosing healthy carbohydrates during pregnancy
Some carbohydrates, especially sugars, are broken down quickly by the body and can cause a rapid increase in blood glucose and insulin levels. These are known as high GI foods, scoring highly on the glycaemic index – the rating system that indicates how quickly food affects your blood sugar.
High GI foods include many refined foods like white bread, white rice, sugary foods such as cakes and biscuits, and potatoes.
Foods that are broken down more slowly are categorised as low GI foods – these keep blood sugar levels more stable. Low GI starchy foods are considered to be healthier and should be selected
Examples of low GI carbohydrates include:
- Sweet potatoes
- Porridge made from rolled oats
- Chickpeas and other pulses
breads, cereals and pastas
A diet based on these healthier starches can help you ensure your blood sugar levels remain steady, reducing your risk of gestational diabetes as well as other pregnancy complications.
A sensible approach is to eat a wide variety of slow-release, fibre-rich low GI carbohydrates, balanced with some higher GI foods to provide an energy boost
The importance of fibre
Fruit and vegetables, wholegrain foods, and potatoes, particularly when eaten with their skin on, are all sources of fibre. Also a carbohydrate, fibre helps to keep your digestive system healthy and regular. This is especially important during

A note about hygiene with rice and grains
Cooked rice and grains left at room temperature can be a breeding ground for bacteria that can make you ill. To minimise any risk, cook these foods ready for when you need them, rather than preparing them ahead of time.
If you do need to prepare rice or grains in advance, or if you have leftovers you’d like to use, make sure you refrigerate them within an hour of cooking and eat them within 24 hours. You should throw away any rice and grains that have been left at room temperature overnight and never reheat them more than once.
Always follow best before dates and storage guidelines on pre-prepared foods made with rice and grains.

- Wholemeal bread
- Potato/sweet potato/yams
- Bulgur wheat
