A quote from Gary Mannion, "Indigo Child" and all-round New Age crackpot:

"I am finding a lot with working with kids that although they may not of had addatives before their problems started their parents have had addatives and this has passed on in dna..."

Is there are truth behind this? An internet trawl turned up this article:

Soft drink additive damages DNA: report
Monday May 28 05:00 AEST
By ninemsn staff

A common preservative found in many soft drinks can cause serious cell damage and fatal illness, according to a UK study revealed last night.

Research indicates that sodium benzoate, an ingredient in many soft drinks and sauces, has the ability to deactivate parts of DNA and eventually cause diseases such as Parkinson's and cirrhosis of the liver.

HEALTH: the truth about soft drinks and your body
Sodium benzoate is indicated in Australia as "Preservative (211)" on ingredients lists, and is included in Sunkist, Diet Coke, Sprite, Pepsi Max and many other drinks and condiments.

Peter Piper, a professor of molecular biology and biotechnology who has been studying sodium benzoate for eight years at Sheffield University, found that the preservative seriously damages living cells.

"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," Prof Piper told The Independent on Sunday.

The findings came from laboratory tests conducted with sodium benzoate on living yeast cells. Prof Piper was alarmed by the chemical's destructive impact on the "power station" of the cells known as the mitochondria.

"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," Prof Piper continued.

"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."

Sodium benzoate occurs in small amounts naturally in berries, but is used in large quantities to prevent mould in soft drinks.

The additive has been the subject of controversy for some time. Last year it was revealed that a chemical reaction between sodium benzoate and vitamin C creates benzene, a carcinogenic chemical.

"The food industry will say these compounds have been tested and they are complete safe," Prof Piper 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 twice about letting their children drink products containing the chemical.

"My concern is for children who are drinking large amounts," he said.


What do you think - scaremongering or a legitimate cause for concern?
 
Dosage used in the study?

I suspect that the yeast was submerged in a fluid that contained 100's of time the amounts found in soft drinks. Of course it's bad for yeast in submergence- it is SUPPOSED to kill molds within the drinks.

Any discussion of what happens to the sb after ingestion? I suspect that in the stomach, it breaks down into sodium ions, and baking soda? ersomthin.

SO, do NOT allow children to bathe in a tub of sodium benzoate, and they won't get such a large dose of it.
 
Hard to say without knowing the concentrations used in the original paper. I think I found it at PubMed but the whole paper is behind a pay wall.

<rant>Personally think that researchers should be banned from giving quotes to reporters unless they make all their research available to the public who have usually paid for it already.</rant>

A little more info in an Independentarticle.

Faintly reassuring was :-
A review of sodium benzoate by the World Health Organisation in 2000 concluded that it was safe, but it noted that the available science supporting its safety was "limited".

But definitely worrying was :-
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
 
I am amazed that McDonalds hasn't sued somebody. Their meals have been labled as both artery clogging and carcinogenic. A Big Mac, fries and a coke now sounds like a last meal instead of a happy meal. Why not just toss in pack of Camels for dessert!But doctors would be in the red without them.
