Eating leafy green vegetables may be good for health, but if roasted they may cause dental erosion, according to scientists in Scotland.

Fruits and vegetables tend to be quite acidic in nature and when they are roasted, they become more acidic like fizzy drinks, the online edition of the Daily Mail reported.

The study by researchers at the University of Dundee, Scotland, found that oven-roasting aubergines, green peppers, courgettes and ratatouille - a traditional French stewed vegetable dish - significantly increased its acidity as compared to stewing.

The study, published in the current edition of the European Journal of Prosthodontics and Restorative Dentistry, also says that the acidity caused by oven-roasting these vegetables amounts to the acidity resulting from certain carbonated drinks, when consumed in excess, and is believed to cause dental erosion.

However, they found the cooking method had no impact on the acidity of tomatoes or onions.
