Why?
Despite much research and the experiences of millions of mums-to-be, it is still unclear exactly why we crave certain foods or even non foods – called pica – during pregnancy (Davina McCall had an urge to chew on bath sponges…). Some say hormonal changes are responsible, or a need for certain nutrients. There’s no scientific evidence to back these theories up though, so we know cravings happen but don’t know the reason for them.
When?
Pregnancy cravings can strike at any stage, but are common in the early weeks and can change throughout your pregnancy. They may even be a sign you’re expecting.
What?
Sour and spicy foods are popular craves, along with pickles, red meat, dairy products and chocolate.

How?
Cravings can be mild or intense, but however they strike you, try and keep the rest of your diet as well-balanced as you can to help keep you and your baby healthy. You only need about another 300 calories a day when you’re pregnant, so make them as healthy as possible. Take a look at the Bounty Your Pregnancy guide for healthy eating information.
Who says?
Doctors and health experts advise that as long as what you really, really want isn’t harmful and is in moderation, pregnancy cravings are not a problem: ‘As long as you stick to a healthy food intake and don’t eat too much of something unsuitable, like foods that are high in fat or sugar, don’t worry: you’ll find that your craving will pass,’ says paediatric dietician, Lucy Findlay. But always discuss it with your midwife or doctor if you are in any way concerned.
