Health Update: Fruitful fizz

FRUIT juice may be worse for children's teeth than fizzy drinks such as cola, according to researchers from Guy's Hospital Dental School. Fruit juice, they point out in General Practitioner, not only contains almost as much sugar as carbonated drinks, but also has a high acid content that can erode enamel. Pure citrus juice contains most acid, followed by orange and blackcurrant squashes. Cola is low in acid and rich in phosphorous, which could strengthen tooth enamel.
