Gender bending chemicals in food packaging, drink cans and baby bottles may double the risk of heart disease, researchers have found.
They have shown that people with higher than normal levels of bisphenol A (BPA) in their blood are more likely to suffer from heart problems.
BPA is used to make linings of food and drink cans. It is also found in plastic bottles, CD cases, plastic knives and forks and dental sealants.
Although some animal studies have suggested that it is safe, others have raised serious concerns.
BPA, which mimics the female sex hormone oestrogen, has been linked in animals to breast cancer, liver damage, obesity, diabetes, fertility problems in males and developmental disorders in the young.
Professor David Melzer, of the Peninsula Medical School, Exeter, who led the research, said: ‘Our study has revealed for the first time an association between raised BPA loads and two common diseases in adults.
At the moment we can’t be absolutely sure that BPA is the direct cause of the extra cases of heart disease and diabetes – if it is, some causes of these serious conditions could prevented by reducing BPA exposure.’
The study, published today in the Journal of the American Medical Association, looked at blood and urine samples of 1,455 adults aged between 18 and 74 years.
The levels of BPA in the study were well below official safety standards, but the 25 per cent of people with the highest levels of BPA were twice as likely to suffer heart disease or diabetes than the bottom 25 per cent.
Higher levels were also linked to abnormal concentrations of liver enzymes, a possible sign of liver damage. The links were strongest for young people.
Comments from Daily Mail’s website:
“…the people in the study were consuming around 20 micrograms of the chemical a day. The minimum safety level is around 3,000 micrograms a day.”
But what about the cumulative effects in the body???

“The levels were well below official safety standards”
So the official safety standards are probably far too high. Logically, this finding would now call for a review of the official safety standards. But since the manufactureres themselves can choose which research to submit to the authorities which set the standards, then we should not hold our breath.

Its about time we switch back to inert natural products like glass for packaging which incidentally is 100% recyclable as well. At least glass doesn’t pollute or poison your internal systems over periods of time. Why in America are baby feeder bottles reverting to glass ones instead of plastic? This is a time-bomb for all of us. We need to change now for the sake of our children and our children’s children before its too late.
