While we've always known that the likes of white bread, cakes and biscuits are bad for our waistlines, new research by the World Health Organisation has confirmed they're also rubbish for our teeth, too.

After reviewing 33 studies on the link between starchy foods (aka carbs) and oral health, researchers concluded that eating more processed carbohydrates is linked to cavities.

The reason is actually pretty obvious when you think about it: carbs are broken down into sugars in your mouth – and sugar, as we're sure your granny told you, equals bad news for your pearly whites.

But it's not all bad news for carb lovers: the researchers also found that consuming wholegrain varieties, including wholemeal bread and pasta, may offer some protection from gum disease and may even help lower your risk of developing oral cancer.

Professor Moynihan, whose work has been published in the Journal of Dental Research, continued: 'Despite an ill-advised fashion for eliminating carbohydrates from the diet, a carbohydrate-rich diet is shown to be fine for oral health, so long as it is low in sugars and is based on whole grain varieties of carbs such as pasta, couscous and wholemeal bread. 

'They key for shoppers is to look for wholemeal and wholegrain on the labels.'
