Top Healing Foods That Stop Ovarian Cancer in its Tracks

Ovarian cancer is one of the most deadly diseases out there. It is the fifth leading cause of cancer death among U.S. women — an astounding 14,000 out of 23,000 diagnosed each year, die. Ovarian cancer tends to be aggressive and generally has very few symptoms until it reaches an advanced stage. Fortunately, several natural remedies have proven to be exceptionally useful in both preventing and curing this silent killer. Ginger, ginkgo biloba, green tea and flaxseed are all remarkably effective at destroying ovarian cancer cells and tumors — hindering proliferation and increasing survival rates dramatically. Diet is extremely influential in preventing as well as healing ovarian cancer. Beyond consuming an abundant variety of fresh produce and limiting dairy, meat and sugar, certain foods specifically target ovarian cancer cells — demonstrating extraordinary success in defeating this life-threatening disease.

Scientists: New GMO wheat may 'silence' vital human genes 

Australian scientists are expressing grave concerns over a new type of genetically engineered wheat that may cause major health problems for people that consume it.
University of Canterbury Professor Jack Heinemann announced the results of his genetic research into the wheat, a type developed by Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), at a press conference last month.

"What we found is that the molecules created in this wheat, intended to silence wheat genes, can match human genes, and through ingestion, these molecules can enter human beings and potentially silence our genes," Heinemann stated. "The findings are absolutely assured. There is no doubt that these matches exist."
Flinders University Professor Judy Carman and Safe Food Foundation Director Scott Kinnear concurred with Heinemann's analysis.
"If this silences the same gene in us that it silences in the wheat -- well, children who are born with this enzyme not working tend to die by the age of about five," Carman said.
Digital Journal contacted Heniemann and Kinnear for more information on their research and future actions they may take regarding this issue.
"To date we have not heard from CSIRO, nor are we aware that CSIRO has released any safety studies into the GM wheat," Kinnear said in an email response. "We are in the final stages of drafting a formal letter to CSIRO which will be requesting further information and asking for them to undertake the studies that are recommended in our reports."
According to the researchers, extended testing should be performed before the wheat is put on store shelves. "We firmly believe that long term chronic toxicological feeding studies are required in addition to the detailed requests made by Heinemann for the DNA sequences used," Kinnear stated.
"The industry routinely does feeding studies anyway, so it should not be too much more difficult to do long term (lifetime) studies and include inhalation studies," Heinemann added. "These should be tuned to the way people would be exposed to the product."
The researchers also cautioned consumers against eating the wheat if it is approved prematurely. "I would advise citizens to request that these tests be done and the evidence meet with their standards of scientific rigour if in the end it is approved for use," said Heinemann.
If the concerns surrounding CSIRO's GM wheat are not resolved, the issue could end up in court, according to Kinnear: "If CSIRO was to consider moving towards human feeding trials without conducting these studies, we would be looking at what legal avenues are available to stop them."

US Biofuel Is Consuming Corn While The World Is Facing Food Crisis

The global food crisis is looming while the US ethanol program is pushing up corn prices by up to 21 percent as it is expanded to consume 40 percent of the harvest. The poor countries and the poor are paying the price. Biofuel is increasing hunger. Now is the time to call: “put food before fuel and people before cars.”

Africa is the most afflicted, with six of the seven states are at extreme risk. Fourteen countries are particularly vulnerable to the recent food-price increase. The food crisis reality questions the biofuel production and consumption.

Timothy A Wise, the Policy Research Director, Global Development and Environment Institute, Tufts University, Medford writes in an essay [1]:

“This is the third food price spike in the last five years, and this time the finger is being pointed squarely at biofuels. [T]he loss of a quarter or more of the projected US corn harvest has prompted urgent calls for reform in that country's corn ethanol program.”

Excerpt from the essay:

“As I showed in my recent study, The Costs to Developing Countries of US Ethanol Expansion, the US ethanol program pushed up corn prices by up to 21 percent as it expanded to consume 40 percent of the US harvest. This price premium was passed on to corn importers, adding an estimated $11.6bn to the import bills of the world's corn-importing countries since 2005. More than half of that - $6.6bn - was paid by developing countries between 2005 and 2010. The highest cost was borne by the biggest corn importers. Mexico paid $1.1bn more for its corn, Egypt $727m.

“Besides Egypt, North African countries saw particularly high ethanol-related losses: Algeria ($329m), Morocco ($236m), Tunisia ($99m) and Libya ($68m). Impacts were also high in other strife-torn countries in the region - Syria ($242m), Iran ($492m) and Yemen ($58m). North Africa impacts totaled $1.4bn. Scaled to population size, these economic losses were at least as severe as those seen in Mexico. The link between high food prices and unrest in the region is by now well documented, and US ethanol is contributing to that instability.

“The debate over biofuels has grown urgent since food prices first spiked in 2007-2008, ushering in a food crisis characterized by repeated jumps in global food prices. Prices for most staple foods doubled, fell when the bubble burst in 2009, then jumped again to their previous high levels in 2010-2011.

“Experts have debated how much of the price increases should be blamed on global biofuels expansion. Few argue now that the contribution is small. A US National Academy of Sciences review attributed 20-40 percent of the 2007-2008 price spikes to global biofuels expansion. Subsequent studies have confirmed this range for the later price increases.

“Why is the impact so large? Because so much food and feed is now diverted to produce fuel, and so much land is now used for biofuels feedstocks - corn and sugar for ethanol, soybeans, palm oil and a variety of other plants for biodiesel. This rapidly growing market was fuelled by a wide range of government incentives and mandates and by the rising price of petroleum.

“Nowhere is the impact clearer than in the diversion of US corn into ethanol production. Ethanol now consumes roughly 40 percent of the US corn crop, up from just 5 percent a decade ago. The biggest jump came after the US Congress enacted the RFS in 2005 then expanded it dramatically in 2007.

“A blending allowance of 10 percent for domestic gasoline added to the demand, a level now potentially being raised to 15 percent. These mandates for rising corn ethanol production combined with tax incentives to gasoline blenders and tariff protection against cheaper imports to create today's massive ethanol demand for corn.

“As corn prices rose farmers increased production, but not enough to accommodate the increased ethanol demand. So prices just kept rising and corn stocks just kept getting thinner and thinner. They were at dangerously low levels - about 15 percent of global use - when the first price spikes happened in 2007-2008. They are at 14 percent now.

“Corn is probably the most problematic feedstock for biofuels. In many parts of the world it is grown as food for human consumption, serving as the staple grain for some one billion people worldwide. It is also a key feed for livestock, giving it another direct link to the human food supply through meat, dairy and egg prices.

“US corn ethanol is particularly disruptive to international markets. The United States is by far the largest producer and exporter of corn in the world. That 40 percent of the US corn crop being put into US cars represents an astonishing 15 percent of global corn production. The diversion of so much corn from food and feed markets has produced a ‘demand shock’ in international markets since 2004.

“For our study of the impacts on corn importers, we relied on estimates of how much lower corn prices would have been if ethanol production had not grown past its 2004 levels. The impacts rose with ethanol demand, reaching an estimated 21 percent in 2009. We took those annual estimates and calculated the added cost each year, 2005-10, to the world's net corn-importing countries based on their net import volumes.

“The largest importer by far is Japan and the ethanol premium cost Japan an estimated $2.2bn. But our interest was developing countries because of their vulnerability to food price increases.

“Over the last 50 years, and particularly since the 1980s, the world's least developed countries have gone from being small net exporters of agricultural goods to huge net importers. The shift came when structural reforms in the 1980s forced indebted developing country governments to open their economies to agricultural imports while reducing their support for domestic farmers. The result: a flood of cheap and often-subsidised imports from rich countries, forcing local farmers out of business and off the land.

“In the price spike of 2008, the world's least developed countries imported $26.6bn in agricultural goods and exported only $9.1bn, leaving an agricultural trade deficit for these overwhelmingly agricultural countries of $17.5bn, more than three times the deficit recorded in 2000 ($4.9bn). This squeezes government budgets, strains limited foreign exchange reserves and leaves the poor more exposed to food price increases.

“Guatemala, for example, saw its import dependence in corn grow from 9 percent in the early 1990s to around 40 percent today. This in a corn-producing country, the birthplace of domesticated corn. According to our estimates, Guatemala saw $91bn in ethanol-related impacts, $28m in 2010 alone. How big an impact is that? It represents six times the level of US agricultural aid that year and nearly as much as US food aid to Guatemala. It is equivalent to over 10 percent of the government's annual expenditure on agricultural development. It is devastating for a country in which nearly half of children under five are malnourished.

“Of course, poor consumers are the ones most hurt by ethanol-related price increases, especially those in urban areas. Even in a net corn exporting country like Uganda, domestic corn prices spiked as international prices transmitted to local markets. Ugandans spend on average 65 percent of their cash income on food, with poor urban consumers getting 20 percent of their calories from corn purchased in the marketplace. More than half of Ugandans were considered "food insecure" in 2007, and the price spikes have only made that worse.

“US ethanol expansion has accounted for 21 percent of corn prices in recent years, so it has forced thousands of Ugandans deeper into poverty and hunger.

“The US and other Northern governments can stop fuelling the food crisis with reckless biofuels expansion. The US can waive the RFS mandates to allow tight markets to adjust in a year of drought. It can join the European Union in reconsidering its mandates. It can halt the increase in blending targets to 15 percent.

“On World Food Day, October 16, the FAO will convene an emergency meeting on the food crisis in Rome. Disgracefully, the G-20 group of economically powerful nations declined to convene its own emergency meeting, with a US spokesperson saying that ‘agricultural commodity markets are functioning’.

“Global leaders should take a strong stand in Rome against biofuels expansion, endorse the use of food reserves to cushion markets in times of drought, demand rules to end financial speculation on food commodities and restrict the land grabs that are driven largely by global demand for biofuels.”

Timothy A Wise concludes his essay with the following call:

“It's time we put food before fuel and people before cars.”

Citing global risk analysis firm Maplecroft’s food security index for 2013 Joshua Berlinger writes [2] in Business Insider on Oct. 10, 2012:

Africa is clearly the most afflicted, with six of the seven states at "extreme risk." Afghanistan was the only nation outside of Africa at extreme risk.

Food insecurity could also become yet another factor fueling the already tense relations and civil unrest in the Middle East.

At the current rate, Rabobank, a financial specialist in agro-commodities, estimates that prices of food staples could rise by as much as 15 percent by June 2013.

Another report [3] adds:

Sub-Saharan Africa, a region that depends largely on food imports, appears to be on the verge of a serious food crisis.

Food-price hikes have been witnessed across the globe. Indeed, the Food and Agricultural Organisation announced last week that food prices rose slightly in September, approaching levels reached during the global food crisis in 2008.

The World Bank has also said that its Food Price Index soared by 10 percent in July compared to a month earlier. Over the same period, prices of maize increased by almost 25 percent and wheat prices surged by around 30 percent.

The high proportion of expenditures on food, high rates of malnutrition and the recurrent crisis and insecurity -- particularly in the Sahel region -- are enough reason for increased concern and monitoring, the bank said.

Aside from the external factors, the presence of desert locusts and ongoing conflict in the Sahel region of West Africa have also been linked to the risk of a food crisis in the region.

In its April issue of Africa’s Pulse, the World Bank mentioned countries like Mali and Niger as already suffering from locust infestation and said there is potential for the swarm to move to neighboring countries such as Mauritania and Chad.

“The impact of this latest food-price increase in local markets across Africa is difficult to determine as current trends show significant variation in domestic prices across the region. In West and Central Africa, prices of cereals are still at record high levels owing to low production in 2011. However, better rains in 2012 have caused prices in the coastal countries to decline...” the bank said in the October edition of Africa’s Pulse.

A recent report by the FAO and USAID’s Famine Early Warning System Network lists 14 countries as being particularly vulnerable to the recent food-price increase. In many of these countries, maize and wheat provide 20% or more of the average household’s caloric intake. For Lesotho, the figure is as high as 69% and for Malawi it is 52%.

In Ghana, rice remains a major staple in particularly urban households which have a taste for imported rice. The country’s own self-sufficiency rate of rice is estimated at 33%. A huge chunk of the rice the country consumes is imported.

Information on the National Rice Development Strategy for Ghana reveals that the per capita rice consumption in Ghana is currently 38 kg, and this is expected to rise to 63kg in 2015 -- giving an aggregate demand of 1.68mn metric tones.

Ghana's demand for rice hovers around 700,000 metric tones, but the local Ghanaian rice farmer is able to produce only 150,000, leaving a deficit of 550,000 metric tones.

According to the Alliance for a Green Revolution in Africa, despite overall strong economic growth over the past decade, the agricultural sector in Ghana has declined from 51 percent to 36 percent of GDP.

The rural poor now account for almost three-quarters of all Ghanaians who live below the poverty line. Smallholder farmers, whose farms average just 1.2 ha, currently have limited opportunities to prosper.

'Miracle grass' encourages longevity while dispelling disease

 More potent than ginseng, jiaogulan is a powerful antidote to aging, cancer, cardiovascular disease, stress and fatigue. It even helps to maintain proper weight. Known as an immortality elixir, this herb has been used for centuries throughout Asia. Jiaogulan is a top notch tonic for modern life too -- a true herbal champion for healthy and dynamic living.

First recorded in the Materia Medica for the Salvation of Starvation during the Ming Dynasty in China, jiaogulan (Gynostemma pentaphyllum) was the go-to herb for a variety of ailments. Often referred to as 'miracle grass,' jiaogulan has a long history of use. Containing four times the amount of saponins compared to ginseng, jiaogulan is an extraordinary adaptogen. American scientists have found it to be one of the top 10 most effective anti-aging herbs in the world.

The secret to longevity and absence of disease

The Chinese mountainous region of Guizhou is famous for its sheer number of centenarians. After 10 years of research, scientists discovered a common link among these long-lived people: daily consumption of sweet tasting jiaogulan tea. The centenarians also had very low incidences of Alzheimer's, cancer, diabetes and high blood pressure. Researchers believe such disease-free longevity is due to the abundance of antioxidants and saponins found in the herb.

Jiaogulan is also recognized as a general health elixir that supports endurance and strength while alleviating fatigue. Furthermore, it has been used with great success in treating the common cold and other infectious diseases.

Formidable anti-cancer tonic

Jiaogulan works on several levels to prevent and heal cancer. As an exceptional source of antioxidants, jiaogulan scavenges free radicals within the body -- minimizing DNA mutations that lead to tumors. The saponins present in jiaogulan also limit the growth of cancer by reacting with the cholesterol rich membranes surrounding rogue cells. Jiaogulan increases white blood cell counts too. In a Chinese study, cancer patients who had suppressed white blood cell activity due to radiation therapy, were given either jiaogulan, an herbal blend or a generic health tonic. Those who took jiaogulan, more than doubled their white blood cell count in an average of five days with almost 94 percent effectiveness.

Incomparable adaptogen

Adaptogens by their very nature have no side effects and only restore balance where needed. Jiaogulan may be the most powerful adaptogen of all as it contains over 100 saponins. Keep in mind the important influence saponins have on health -- regulating cholesterol, reducing cancer risk while enhancing immunity.

Through its adaptogenic properties, jiaogulan supports equilibrium within the body. If an individual needs to shed extra pounds, jiaogulan can help. Interestingly, the reverse is also true. If someone is underweight, the herb will assist in correcting that imbalance as well. Additionally, jiaogulan will regulate cholesterol and blood pressure whether too high or low. The nervous system is similar -- if anxiety ridden, jiaogulan has a calming effect; if dullness is present, the herb is energizing.

It is important to note that jiaogulan grown in Southeast Asia is often contaminated with heavy metals. Always chose organic, sustainably grown varieties to avoid potential toxins.

For those seeking youthfulness, health and vibrancy, jiaogulan might just be the answer. As an unbeatable adaptogen and supreme source of antioxidants as well as saponins, jiaogulan is a tasty way to enjoy the sweet life.

If America Only Knew How Much Arsenic Ends Up on the Average Dinner Plate

The American right wing loves to hate Big Government, but does size matter? Perhaps the problem is not Big Government, but Dumb Government, Inefficient Government or even Corrupt, Sold-Out, or Inept Government. The recent bombshell Consumers Union, publisher of Consumer Reports, dropped – that rice contains dangerous levels of arsenic [3] – illustrates how good, effective government can save lives by keeping deadly toxins out of the food supply whereas our federal bureaucracy (aided, abetted and cajoled by industry) has instead let us down.

Arsenic [4] “is considered the number one environmental chemical of concern for human health effects both in the U.S. and worldwide,” according to information published by Darmouth Toxic Metals Superfund Research Program. It can be divided into two categories: organic and inorganic. While organic arsenic is itself a probable human carcinogen, inorganic arsenic is a definite human carcinogen that is linked to liver, lung, kidney, bladder, and skin cancer as well as “increased risk of vascular and heart disease, type 2 diabetes, reproductive and developmental disorders, low birth weights in babies, neurological and cognitive problems, immunodeficiencies, metabolic disorders, and a growing list of other serious outcomes.”

In short: you don’t want this in your food.

“When you're talking about a carcinogen [like arsenic], there is no safe level,” Consumers Union’s senior scientist Michael Hansen explains. Instead of eliminating all risk, one looks at carcinogens in terms of levels of risk. For example, Consumers Union provides a table explaining how much rice one can eat [5] to achieve a 1 in 1,000 lifetime risk of cancer. The federal government does not limit the amount of arsenic allowed in food, so Consumers Union based its standard on the EPA’s initial recommendation for arsenic limits in drinking water (five parts per billion).

In fact, the drinking water standard – which is now set at 10 parts per billion (ppb) – is a fine place to begin the story of how government, industry and arsenic fit together. Arsenic is a naturally occurring element, but the U.S. has increased the amount of arsenic in our environment and our farmland over the past century by using 1.6 million tons of it in agricultural and industrial uses. About half of that amount has been used since the mid-1960s.

Once in the environment, arsenic – a chemical element and a heavy metal – does not break down and go away as do some toxins. Once so much arsenic was sprayed on farms, it was in the environment for good – and it could find its way into our food and water. U.S. limits on arsenic in drinking water were set at 50 ppb [6] in 1942, before arsenic was classified as a carcinogen. But a 1999 report by the National Academy of Sciences showed that this level failed to protect Americans from an unacceptably high risk of cancer.

The EPA then proposed lowering the limit for arsenic from 50 ppb to just 5 ppb in 2000. Industry complained, and the Clinton-era EPA settled upon lowering the limit to just 10 ppb instead. Once George W. Bush took office, he initially attempted to block the change [7], thus keeping the World War II-era limit of 50 ppb. By November 2001, the Bush administration gave in to allowing the 10 ppb limit to go forward. Even still, Sen. Barbara Boxer noted that this 10 ppb limit would allow three times as much cancer risk as the EPA’s usual goal.

Arsenic in food deserves some special concern, and yet there are no regulations limiting it. In addition to arsenic used in industry that finds its way onto farms, there is arsenic used in agriculture that the farmers themselves bring to their farms, a practice almost dating back to the Civil War.

Long before the days of DDT, the first synthetic pesticides were arsenicals. An arsenical paint pigment called Paris green was first used against Colorado potato beetles in 1867. Even then, arsenic’s deadly toxicity was well known – Will Allen tells in his book, The War on Bugs, how farmers lost cattle after they ate potato plants treated with Paris green. Other arsenic pesticides, London purple and lead arsenic, soon followed Paris green onto the market. By the 1930s, “well over a hundred million people in the United States suffered from mild to severe arsenic and lead poisoning,” writes Allen.

Yet the end of arsenic as a favored pesticide did not come from government – it came from nature and from the chemical companies. As pests evolved resistance to arsenical pesticides and as chemical companies supplanted arsenicals with newer products, arsenicals fell out of favor. Only then did the government begin canceling some of the registrations of arsenical pesticides.

And yet, even after arsenicals were displaced by other pesticides for most uses, half of the arsenic used in the U.S. has been in the last half century. Recent uses of arsenic fall into two categories: livestock drugs and pesticides.

Until recently, the arsenical livestock drugs roxarsone, nitarsone, carbarsone and arsanilic acid were all used in chickens, turkeys and swine. Roxarsone [8] was widely used for disease prevention, weight gain, feed efficiency and improved pigmentation in chickens from 1944 until it was voluntarily removed from the market by Pfizer in 2011 following the revelation that chickens fed roxarsone had inorganic arsenic in their livers. The latter three are all still legal, regulated by the Food and Drug Administration.

Once used in chickens, the arsenic in roxarsone remained in the chickens’ litter, which consists of bedding, droppings, feathers, and dropped feed. Poultry litter, in turn, served as fertilizer on farms and – believe it or not – cattle feed. And, as it turns out, the top rice-producing state in the U.S., Arkansas [9], is in second place behind Georgia for broiler production. (Of the six rice-producing states, all rank among the nation’s top broiler producers, with Mississippi and Texas among the top five, and California and Missouri among the top 10.)

As pesticides, many arsenicals were phased out over the years, but some uses remain. In 2006, the EPA attempted to essentially ban the remaining uses of organic arsenicals [10], because "following application, these pesticides convert over time to a more toxic form in soil, inorganic arsenic, and potentially contaminate drinking water through soil runoff." Following outcry from industry, EPA backed away from its initial decision.

All organic arsenicals except one herbicide, monosodium methanearsonate (MSMA), were banned as of 2009. After that time, MSMA could still be used on sod farms, golf courses and highway rights of way until the end of 2013. After that, only one remaining us of any organic arsenical would be permitted: MSMA on cotton.

As luck would have it, the six rice-growing states are among the top cotton-growing states [11]: Texas, Mississippi and Arkansas top the list, with California, Louisiana and Missouri each growing significant cotton acreage as well. Rice is so susceptible to taking up arsenic because it is often grown in fields flooded with water. In fact, a 2008 study [12] found that growers can reduce the amount of total and inorganic arsenic in rice by growing it under “aerobic” (not flooded) conditions. And yet the same states that grow rice are also the cotton-growing states where MSMA is still used.

So why does the EPA still allow MSMA on cotton if arsenicals are so bad that they are banned on absolutely everything else? Two words: Palmer amaranth. Despite years of warnings, biotech and chemical companies and cotton growers have created the perfect weed. Palmer amaranth has evolved resistance to both ALS inhibitor herbicides and to glyphosate, the active ingredient in Monsanto’s Roundup, and one plant can produce half a million seeds.

Weeds commonly evolve resistance to ALS inhibitors [13], much more so than for any other class of herbicides. But resistance to glyphosate was almost unheard of before Monsanto first introduced its Roundup Ready genetically engineered crops to the market in 1996. Glyphosate use shot up, giving weeds the evolutionary force needed to develop resistance. Nowhere was this truer than on fields that rotated between two Roundup Ready crops, soybeans and cotton.

Glyphosate-resistant Palmer amaranth first turned up in GE soybeans and cotton in Georgia in 2005 [14] and before long it was documented across the U.S. including in the rice-growing states of Arkansas, Mississippi, Missouri, Louisiana, and California. In some case, resistance to both types of herbicides was found in the same Palmer amaranth plant. The weed has caused growers to turn to more toxic herbicides, hand-weeding, and even entirely abandoning their fields.

One last direct outlet for arsenic into agricultural lands comes from sewage sludge. Under current EPA regulations, sewage sludge containing 41 parts per million – 41,000 parts per billion – total arsenic can be applied to agricultural land and even sold to consumers for home garden and lawn use. (Full disclosure: I recently worked on the Center for Media & Democracy’s sewage sludge campaign [15], which opposed the use of sewage sludge in agriculture.) Under existing law [16], farmers can apply sewage sludge containing up to 41 kilograms of arsenic per hectare of land.

As you can see, between them, the USDA, FDA and EPA have allowed pesticides, pharmaceuticals and practices that led to the toxic load of arsenic Consumers Union found in rice. The EPA regulated pesticides, the FDA regulated drugs, and the USDA worked with farmers in many aspects of agriculture and gave the green light to Roundup Ready crops. It was no secret that arsenic was going into farms and fields where our food is grown, and yet the question of where the arsenic went was mostly ignored. The FDA recently released its own tests [17], confirming Consumers’ Union’s findings. As their data shows, even organic rice contains arsenic. (Organic farmers cannot use arsenical pesticides, but they can use manure from chickens fed roxarsone and other arsenical drugs.)

So is the government to blame for this massive oversight and public health risk? Michael Hansen doesn’t think so. “The issue in the larger context isn't so much that it's bad government,” he says. “If you put it in the proper context, it's not only the gutting of the regulatory agency but also the control by industry and outside forces. I think there are definitely people within the agency who would like to take action on a number of things but they can't because of the reaction by industry… The power of industry is so strong, you can't expect the government to take action when they are trashed left and right.”

Consumers Union recently sent and published three letters, one to the EPA [18], one to the FDA [19] and one to the USDA [20], asking them to rectify all of the problems named in this article so that no more arsenic finds its way into U.S. farms and so that standards are set for how much arsenic is allowed into our food supply. They also commend Congress for introducing the R.I.C.E. Act (Reducing Food-Based Inorganic and Organic Compounds Exposure Act) and they advocate its speedy passage (which is not likely in the current politically charged environment).

When citizens reflect on the size of their government, surely most would agree that it ought to be “big” enough to keep arsenic out of the food supply. But the comedy of errors between three different agencies that allowed so much arsenic onto our farms and then our dinner tables is exactly the sort of disaster that causes voters to throw up their hands and wish the government would go away altogether. Yet, if Hansen is correct, the incompetence shown in this case was not a matter of bureaucratic ineptness but one of industry’s capture over the agencies charged with regulating it. Voters going to the polls need to recognize the problem. Instead of voting for candidates who vow to get government out of our lives we should be voting for leaders willing to take a stand against undue corporate influence.

Jason Mark -- Whoa, Is Organic Food No Healthier Than Non-Organic? Controversy Erupts Over Study

I had barely drank my first cup of coffee when I heard the news yesterday morning on NPR [3] – organic food, it turns out, may not be that much healthier for you than industrial food.

The NPR story was based on a new study published in the Annals of Internal Medicine [4] which concluded, based on a review of existing studies, that there is no “strong evidence that organic foods are significantly more nutritious than conventional foods.” The study, written by researchers at the Stanford School of Medicine, also found that eating organic foods “may reduce exposure to pesticide residues and antibiotic-resistant bacteria.”

The interwebs were soon full of headlines talking down the benefits of organic foods. “Stanford Scientists Cast Doubt on Advantages of Organic Meat and Produce,” the NY Times [5] announced, as reporter Kenneth Chang pointed out that pesticide residues on industrially grown fruits and vegetables are “almost always under the allowed safety limits.”CBS news [6], running the AP story on the Stanford study, informed readers: “Organic food hardly healthier, study suggests.”

Organic agriculture advocates were quick with their rebuttals. The Environmental Working Group [7] put out a press release playing up the researchers’ findings that organic produce has less pesticide residue. Charles Benbrook, a professor of agriculture at Washington State University and former chief scientist at The Organic Center [8], wrote a detailed critique you can find here [9]. Benbrook noted that the Stanford study didn’t include data from the USDA and US EPA about pesticide residue levels. He also pointed out that the researchers’ definition of “significantly more nutritious” was a little squishy.

Is this the last word on the nutritional benefits of organic foods? Hardly. As Benbrook said, in the coming years improved measurement methods will hopefully allow for better comparisons of food nutritional quality. (You can find an Earth Island Journal cover story on this very issue here [10].)

I’ll leave it to the PhDs and MDs to fight this out among themselves. As they do, I’ll keep buying (and growing [11]) organic foods. Why? Because even if organic foods are not demonstrably better for my health than industrial foods, I know that organics are better for the health of other people – the people who grow our nation’s food.

To his credit, NPR’s new ag reporter, Dan Charles, was careful to note that organic agriculture “can bring environmental benefit[s].” One of the most important environmental benefits organic agriculture delivers is a boost to public health and safety.

Let’s say you’re not worried about the relatively small amounts of pesticides that end up on the industrial foods at the supermarket. (Though you should read this [12] Tom Philpott dissection of the Stanford report when considering your risk of eating pesticide residue.) Well, you should still be concerned about the huge amounts of pesticides that end up in the air and water of farming communities – chemicals that can lead to birth defects, endocrine disruption, and neurological and respiratory problems.

When pesticides are sprayed onto farm fields, they don’t just stay in that one place. They seep into the water and waft through the air and accumulate on the shoes and clothes of farm workers. In recent years in California (the country’s top ag producer) an average of 37 pesticide drift incidents [13] a year have made people sick. Pesticides also find their way into the homes of farm workers. A study by researchers at the University of Washington found that the children of farm workers have higher exposure to pesticides [14] than other children in the same community. When researchers in Mexico looked into pesticide exposure of farm workers there, they found that 20 percent of field hands “showed acute poisoning. [15]

The health impacts on those workers were serious and included “diverse alterations of the digestive, neurological, respiratory, circulatory, dermatological, renal, and reproductive system.” The researchers concluded: “there exist health hazards for those farm workers exposed to pesticides, at organic and cellular levels.”

There are shelves’ worth of studies [16] documenting the health dangers of pesticide exposure. A study published last year found that prenatal exposure to organophosphate pesticides [17] – which are often sprayed on crops and in urban areas to control insects – can lower children’s IQ. A follow-up investigation into prenatal pesticide exposure concluded that boys’ developing brains appear to be more vulnerable [18] than girls’ brains. A study by Colorado State University epidemiologist Lori Cragin found that women who drink water containing low levels of the herbicide atrazine are more likely to have low estrogen levels [19] and irregular menstrual cycles; about three-quarters of all US corn fields are treated with atrazine annually. British scientists who examined the health effects of fungicides sprayed on fruits and vegetable crops discovered that 30 out of 37 chemicals studied altered males’ hormone production [20].

Dave Gutknecht -- Farmers Fight Monsanto's Threats and Intimidation

A major lawsuit against Monsanto was denied in at the district court and has been appealed. On July 5, 2012, seventy-five family farmers, seed businesses, and agricultural organizations representing over 300,000 individuals and 4,500 farms filed a brief with the United States Court of Appeals for the Federal Circuit in Washington, D.C., asking the appellate court to reverse a lower court's decision from February dismissing their protective legal action against agricultural giant Monsanto's patents on genetically engineered seed.

The plaintiffs brought the pre-emptive case against Monsanto in March 2011 in the Southern District of New York (Organic Seed Growers and Trade Association et al. v Monsanto) and specifically seek to defend themselves from nearly two dozen of Monsanto's most aggressively asserted patents on GMO seed. They were forced to act pre-emptively to protect themselves from Monsanto's abusive lawsuits, fearing that if GMO seed contaminates their property despite their efforts to prevent such contamination, Monsanto will sue them for patent infringement.

Lead plaintiff in the suit (and the main source for this report) is the Organic Seed Growers and Trade Association (www.osgata.org), a not-for-profit agricultural organization made up of organic farmers, seed growers, seed businesses and supporters. OSGATA is committed to developing and protecting organic seed and its growers in order to ensure the organic community has access to excellent quality organic seed – seed that is free of contaminants and adapted to the diverse needs of local organic agriculture.

Dangerous Drift

Seed and pollen can drift great distances, in some cases as far as 10-15 miles, increasing the likelihood of contamination of organic crops with genetics from Monsanto's laboratories. The latter seeds and crops are referred to as "transgenic," and have had DNA of foreign organisms inserted into their DNA through human engineered processes. The suit plaintiffs use and sell non-transgenic seed, more commonly referred to as heirloom, organic, or conventional seed.

Ethical Dilemmas Contribute to 'Critical Weaknesses' in FDA Postmarket Oversight, Experts Say

 Ethical challenges are central to persistent "critical weaknesses" in the national system for ensuring drug safety, according to a commentary by former Institute of Medicine (IOM) committee members published August 22 in the New England Journal of Medicine.

With a caution against "reactive policymaking," committee co-chairs Ruth Faden, Ph.D., M.P.H., and Steven Goodman, M.D., M.H.S., Ph.D., with fellow committee member Michelle Mello, J.D., Ph.D., revisit the controversy over the antidiabetic drug Avandia that led to the formation of their IOM committee on monitoring drug safety after approval.

The Avandia postmarket trial, halted in September 2010, was "a lesson in how our current approach to the oversight of drug-safety and postmarketing research can fail both the public and the research participants," the authors write. With those lessons in mind, their independent commentary follows the May 2012 IOM report with a focus on the ethical challenges ahead.

The authors detail the IOM report's recommendations for maintaining the delicate balance of drug innovation and drug safety. Increased "fast-tracking" of drug approval for medical conditions with no effective treatment necessitates a counterbalance of increased postmarket oversight, the authors argue. They echo the IOM report's call for an independent ethics advisory board to the Food and Drug Administration (FDA), focused on postmarket research and safety surveillance.

"As the pace of the translation of discoveries from bench to bedside continues to intensify, so too does the imperative for thoughtful ethical governance throughout the lifecycle of a drug," the authors write.

The authors also amplify one of the IOM report's key ethics points -- the responsibility of the FDA to participants in postmarket research, particularly in randomized trials that determine which treatment they receive. The FDA has a unique ethical obligation to the welfare of research participants when requiring a postmarket study, the authors assert, which "cannot be handed off to contractors or the industry sponsor."

"Mitchell J. Rabin" - The Morphogenetic Fields, They Are A'Changin' 

Bob Dylan might not have had that idea exactly when he wrote his folk song that described a movement kicked up in the famous '60's but in effect, he did. British biologist Rupert Sheldrake hadn't yet updated his version of the concept by then, but the notion still existed. And now, as when Dylan was most vocal, there is much afoot. It doesn't always look so pretty, in fact, it rarely does--what with wars raging sponsored by the USA, Big Pharma doing all it can with its government agents, the FDA, to squash our access to nutritional supplements or Monsanto's attempt to control all seed and food production across the globe with governmental cooperation, nation-to-nation. Yes, things don't look good when you see it only through these lenses.
