A new health scare erupted over soft drinks last night amid evidence they may cause serious cell damage. Research from a British university suggests a common preservative found in drinks such as Fanta and Pepsi Max has the ability to switch off vital parts of DNA.The problem - more usually associated with ageing and alcohol abuse - can eventually lead to cirrhosis of the liver and degenerative diseases such as Parkinson's.
The findings could have serious consequences for the hundreds of millions of people worldwide who consume fizzy drinks. They will also intensify the controversy about food additives, which have been linked to hyperactivity in children.
Now, an expert in ageing at Sheffield University, who has been working on sodium benzoate since publishing a research paper in 1999, has decided to speak out about another danger. Professor Peter Piper, a professor of molecular biology and biotechnology, tested the impact of sodium benzoate on living yeast cells in his laboratory. What he found alarmed him: the benzoate was damaging an important area of DNA in the "power station" of cells known as the mitochondria.
He told The Independent on Sunday: "These chemicals have the ability to cause severe damage to DNA in the mitochondria to the point that they totally inactivate it: they knock it out altogether.
"The mitochondria consumes the oxygen to give you energy and if you damage it - as happens in a number if diseased states - then the cell starts to malfunction very seriously. And there is a whole array of diseases that are now being tied to damage to this DNA - Parkinson's and quite a lot of neuro-degenerative diseases, but above all the whole process of ageing."
"The food industry will say these compounds have been tested and they are complete safe," he said. "By the criteria of modern safety testing, the safety tests were inadequate. Like all things, safety testing moves forward and you can conduct a much more rigorous safety test than you could 50 years ago."
He advised parents to think carefully about buying drinks with preservatives until the quantities in products were proved safe by new tests. "My concern is for children who are drinking large amounts," he said.
Coca-Cola and Britvic's Pepsi Max and Diet Pepsi all contain sodium benzoate. Their makers and the British Soft Drinks Association said they entrusted the safety of additives to the Government.
