The trouble with health news is that it's often confusing and hardly ever actionable. Like this for example. One ingredient in cramberry juice prevents dental plaque, but another ingredient can soften enamel and still another can cause cavities.
"A team at Rochester University in New York found that two daily doses of fruit drink containing 25 per cent cranberry juice inhibited bacteria-binding and further accumulation to an artificial tooth surface by 67 to 85 per cent.
"It does seem that cranberries are good news for teeth, but it is important to be aware of the negatives," says Nigel Carter, chief executive of the BDHF. "Cranberry juice is very acidic. Every time you drink something acidic, the enamel on your teeth is softened temporarily which can lead to tooth erosion."
Another problem is that many popular cranberry juice drinks contain high levels of added sugar."
So drink more cranberry juice. Or less.
