Sipping acidic fruit teas can wear away teeth

Sipping acidic drinks such as fruit teas and flavoured water can wear away teeth and damage the enamel, an investigation by scientists has shown.

The King's College London team found that drinking them between meals and savouring them for too long increased the risk of tooth erosion from acid. The research, in the British Dental Journal, looked at the diets of 300 people with severe erosive tooth wear.

It said the problem was increasing as people snacked more. Fruit squashes, cordials, fruit teas, diet drinks, sugared drinks and flavoured water are all acidic and can cause wear and tear to teeth, the researchers said. And continuously sipping or holding these drinks in the mouth before swallowing increased the risk of tooth erosion.

Dr Saoirse O'Toole, the lead study author, from King's College London Dental Institute, said: "If you drink things for long periods of time, greater than five minutes, or if you play with things in your mouth or if you nibble on fruit over a few minutes rather than eating them as a whole fruit - these are things that can really damage your teeth. If you're going to have an apple as a snack at lunchtime, then try not to have anything acidic later on in the evening. If you are going to have a glass of wine in the evening, then don't have your fruit tea in the morning."

Folic acid will be added to flour to prevent birth defects

Folic acid will be added to all flour to stop thousands of children being born with birth defects, such as spina bifida, it was reported last night.

The government is expected to announce a u-turn within weeks after resisting the move for 
26 years. In 1991 the largest trial of its type at the time established a link between the diseases, known collectively as neural tube defects (NTD), and low levels of folic acid in mothers during the early part of pregnancy.

Eighty-one countries, including the US, subsequently introduced the mandatory fortification of flour with folic acid because only approximately one third of women follow advice to supplement their diet. Britain did not follow suit, partly on the basis of a study by the American Institute of Medicine which indicated a risk of neurological damage if folic acid levels become too high.

However following pressure from scientists, and ongoing recommendations from the Scientific Advisory Committee on Nutrition (SACN), Downing Street is to make fortification mandatory, according to The Guardian.  The Royal Society of Medicine also said that the decision was ‘long overdue’ while charities said it was ‘gamechanging.’
