BPA spikes 1,200 percent after eating canned soup

WASHINGTON — People who ate canned soup for five days straight saw their urinary levels of the chemical bisphenol A spike 1,200 percent compared to those who ate fresh soup, US researchers said on Tuesday.
The randomized study, described as “one of the first to quantify BPA levels in humans after ingestion of canned foods,” was done by Harvard University researchers and appears in the Journal of the American Medical Association’s November 23 issue.
“We’ve known for a while that drinking beverages that have been stored in certain hard plastics can increase the amount of BPA in your body,” said lead author Jenny Carwile, a doctoral student in the Department of Epidemiology at Harvard School of Public Health.
“This study suggests that canned foods may be an even greater concern, especially given their wide use.”
The chemical BPA is an endocrine disruptor that has been shown to interfere with reproductive development in animal studies at levels of 50 micrograms per kilogram of body weight and higher, though it remains uncertain if the same effects cross over to humans, according to the Environmental Protection Agency.
This study did not measure BPA levels by micrograms per kilogram of body weight, but rather by micrograms per liter of urine, so a direct comparison to the EPA-cited danger level in animals was not possible.
However, previous studies have linked BPA at lower levels than those found in the Harvard study to cardiovascular disease, diabetes and obesity in humans, Carwile told AFP in an email.
BPA is found in the lining of canned foods, cash register receipts, dental fillings, some plastics and polycarbonate bottles marked with the number 7.
Seventy-five people took part in the study, eating a 12-ounce serving of either fresh or canned soup for five days in a row. They were advised not to otherwise alter their regular eating habits.
After a two-day break, the groups switched and ate the opposite type of canned soup.
A urine analysis showed the canned soup eaters had 1,221 percent higher levels of BPA than those who ate the fresh soup.
BPA is typically eliminated in the urine and so any spike is usually considered temporary. The researchers did not measure how long elevated BPA stayed in the body, saying more study would be needed to examine that question.
The US government’s health and environmental agencies are considering whether “further action is needed to address human health risks resulting from non-food-packaging uses of BPA,” according to the EPA.
France’s Agency for Food Health Safety (Anses) in September called for tougher preventive measures, warning that even “low doses” of the chemical had had a “confirmed” effect on lab animals and a “suspected” effect on humans.
Preventing exposure to BPA among infants, pregnant or nursing women was a “priority goal,” Anses said.
Meanwhile, the Harvard study authors said their findings should encourage people who eat a lot of canned foods to opt for fresh instead, and should serve as a red flag to manufacturers who use BPA to make cans.
“The magnitude of the rise in urinary BPA we observed after just one serving of soup was unexpected and may be of concern among individuals who regularly consume foods from cans or drink several canned beverages daily,” said senior author Karin Michels.
“It may be advisable for manufacturers to consider eliminating BPA from can linings.”

Study: Common Herbicide Causes Menstrual Trouble
While the EPA looks the other way, epidemiological evidence yet again implicates atrazine.
By Tom Philpott | Tue Nov. 29, 2011 4:00 AM PST
Yet again, scientists have looked at populations routinely exposed to the widely used herbicide atrazine and found trouble.
The latest: In a study [1] published by Envionmental Research (summarized here [2]), researchers found evidence that atrazine could be causing menstrual irregularities and low estrogen levels in women, even when it appears in drinking water at levels far below the EPA's limit of 3 parts per billion.
The study showed that women in ag-intensive areas of Illinois, where atrazine has been shown to leach into drinking water from farm fields, were significantly more likely to experience menstrual irregularities and low estrogen levels than women in ag-intensive areas of Vermont, where atrazine use is much lower.
The Vermont/Illinois paper comes on the heels of an analysis [3] of the Agricultural Health Study [4]—an ongoing look at people who regularly apply pesticides and their spouses—that found similar trends among women exposed to atrazine, as well as a 2009 study [5]finding that atrazine levels in drinking water tracked with low-weight birth incidences in Indiana.
Meanwhile, as I reported three weeks ago [6], an independent scientific panel convened by the EPA found "strong" evidence linking atrazine to thyroid cancer and "suggestive" evidence linking it to ovarian cancer, also based on studies of human populations exposed to the poison through drinking water. The panel declared that the EPA had been seriously underestimating the cancer risk posed by atrazine in drinking water.
Now, assessing the danger of a toxic chemical like atrazine, the second-most-used pesticide on US farm fields, is tricky. You can't ethically feed a suspected poison to people and see what happens.
You can use animals to gauge its effects, but it isn't perfectly clear how the results apply to humans. And you can find human populations known to be exposed to it and see if any health concerns turn up—a practice known as epidemiology, and exemplified by the studies I cite above. But here, too, results are uncertain, because real-world situations contain infinite variables that can't be controlled for.
But the absence of definitive proof that exposure to atrazine causes health trouble does not exonerate the lucrative agrichemical [7], as its maker, Syngenta, would have us believe. Until company execs volunteer to start quaffing the stuff and feeding it to their kids, animal studies and epidemiology are all we have. And for atrazine, both point to danger. (A recent University of California-Berkeley study [8] found that low-level exposure to the chemical emasculates male frogs).
After the EPA publicized the findings of its cancer panel earlier this month, an agency spokesperson told me that the EPA would not even consider banning the chemical until 2013, at the earliest. That decision looks more dubious than ever as troubling new evidence emerges about Syngenta's blockbuster herbicide.

A recent study has found that Monsanto’s Roundup pesticide may be responsible for causing infertility. After reviewing the many already well-documented negative impacts Roundup has on the environment and living creatures, it is no surprise to add yet another item to the list.
Monsanto’s Best-Selling Herbicide Roundup Linked to Infertility
Researchers tested roundup on mature male rats at a concentration range between 1 and 10,000 parts per million (ppm), and found that within 1 to 48 hours of exposure, testicular cells of the mature rats were either damaged or killed. According to the study, even at a concentration of 1 ppm, the Roundup was able to affect the test subjects by decreasing their testosterone concentrations by as much as 35%.
How can such small levels of exposure have such a profound effect on the reproductive system?
Roundup, being a glyphosate-based herbicide is also known to have endocrine disrupting properties.
Much like BPA, glyphosate-based herbicides have the ability to interfere with the natural hormonal balance in the human body, thereby introducing a number of health risks along with even the smallest levels of exposure. These chemicals are strong enough to affect your metabolism, behavior and mood, reproductive organs, and even provoke cancer.
As a result, any plants that are sprayed with Roundup carry with them a chemical effect similar to that of other endocrine disruptors, offsetting the hormonal balance and causing adverse effects, despite even the smallest levels of exposure. This in part contributes to the number of males with increased fertility issues in more recent times.
It is no surprise that Monsanto, a company already infamous for a whole slew of dangerous concoctions, would also be responsible for affecting another major aspect of human health on a large scale.
Ultimately it is highly important to avoid any products sprayed with pesticides or herbicides for the many associated health risks – now fertility included. In addition to avoiding food which has been tarnished by this pesticide, you may also want to consider investing in a water filter. Glyphosate, the carcinogenic chemical Roundup contains, has been found to be contaminating the groundwater in areas where it is being applied.
Being aware of the hormonal disruptors you face in your daily life such as BPA and now Roundup is a must. Even the smallest levels of exposure can have large negative effects.

So the USDA is being scaled down, thus by definition consolidating more power in the hands of the FDA. Phew.
Wouldnt it be simply fascinating to run a survey of 100 Western "joes" (who have actually heard of the FDA ),and ask them who does the testing of standards for food and Pharmecuticals ?
Im assuming we all know here of course, right ?

http://www.organicconsumersfund.org/donate/moneybomb.cfmBy midnight tomorrow, May 26, we need to raise $1 million for the California right to Know GMO labeling Campaign so we don't miss out on a $1 million matching gift.
Please join the thousands who have already donated to this historic campaign by donating online, by mail or by phone before midnight Saturday.
Time is running out, so I'll keep this short.
If we all pitch in to help California pass this historic law to require mandatory GMO labeling, it's only a matter of time before all of us, in every state in the US, will finally be able to know if the food we buy contains genetically engineered ingredients.
Big Biotech and Big Food oppose this law. And they are backed by Big Money. Lots of it. Money they've accumulated by poisoning our food and our planet. They've already promised to spend $60 million to convince consumers not to pass this GMO labeling law.
With public opinion on our side, we don't need $60 million. But we need at least several million dollars to stand our ground.
Several million honest dollars, raised by honest organizations, honest companies and honest people like you who are fed up with being fed junk.
We can do this - with your help. With just one day left, we need about $100,000. We're counting on small donations of $5, $10, $20 to get us there.
Every dollar counts! Please donate today and tell Monsanto: We have the right to know if our food contains GMOs. Thank you!
For an Organic Future,
Ronnie Cummins
