Cheese Is Just As Addictive As Hard Drugs

A new study done by the author, Alanna Ketler onCollective-Evolution has shown that cheese obtained from animals can be just as addictive as hard drugs.

Cheese is a very popular ingredient in Western cuisine. It is very common in many traditional foods in the Western world. In the United States for example, it is said the average American consumes about 30 pounds of cheese a year.

According to the article revealing how addictive cheese is, Ketler wrote that dairy actually contains a chemical that is similar to morphine. She stated that in 1981, researchers identified a protein known as casein. Casein is said to be present in all mammals, including humans and cows.



When humans eat dairy, and it begins to digest, the casein releases opiates that are known as casomorphins. Casomorphins are said to be similar to morphine, and belong to the opioid family.

Ketler argued further that when we consider the purpose of breast milk from mothers, it is to provide nourishment for rapidly growing infants and to establish a strong connection between mother and child. This, she said, makes the purpose of casomorphins very clear. It causes addiction.

The majority of cheese consumed on a regular basis, is primarily made from cow’s milk. Ketler revealed that cheese produced from cow’s milk has at least 10 times the amount of casomorphins compared to that of humans (breast milk).

According to Ketler, in the process of converting milk into cheese, about 10 pounds of milk is required to make 1 pound of cheese, which means that the presence of casomorphins is highly concentrated in cheese derived from cows.



Therefore, once you start consuming cheese, it becomes very difficult for you to stop. Using the U.S. as an example again, it is said cheese consumption has nearly tripled in the country since the 1950’s. The only difference between hard drugs and cheese, is that the drugs will let you be ‘high’, but cheese will not.

Cheese will give you health problems once you become addicted to it. Researchers have proven that most humans are lactose intolerant. It is said our bodies are not actually capable of properly breaking down and digesting cheese, and other dairy products. Apart from this, there is also plenty of evidence to suggest links between dairy consumption and a number of serious health concerns; various forms of cancer, obesity, gastrointestinal disorders, and osteoporosis.

Common Chemicals Found In Food, Water and Makeup Are Causing Mass Infertility .

Hormone-disrupting chemicals are everywhere — in plastics, pesticides and makeup — and two of them, phthalates and DDE, have been particularly strongly linked with common female reproductive conditions, such as fibroids.

In a new study, researchers estimate that the problems caused by these two chemicals alone could cost the European Union at least 1.41 billion euros a year, the U.S. equivalent of about $1.58 billion.

Hormone-disrupting chemicals are everywhere — in plastics, pesticides and makeup — and two of them, phthalates and DDE, have been particularly strongly linked with common female reproductive conditions, such as fibroids.

In a new study, researchers estimate that the problems caused by these two chemicals alone could cost the European Union at least 1.41 billion euros a year, the U.S. equivalent of about $1.58 billion.
A panel of experts previously estimated the health cost of a range of endocrine-disrupting chemicals — of which bisphenol-A, or BPA, is probably the most infamous — based on a slew of conditions they have been associated with, including obesity, IQ loss and male infertility.
The economic toll attributed to the chemicals in that analysis was 157 billion euros, or $177 billion.
For the current study, the researchers turned their attention toward fibroids and endometriosis, two common conditions that affect an estimated 70% of women and are leading causes of female infertility
The researchers looked at studies of many different endocrine-disrupting chemicals and determined that the strongest evidence, albeit still from only a handful of studies, implicated a role for DDE, or diphenyldichloroethene, and phthalates in fibroids and endometriosis, respectively.
“There are substantial human and toxicological studies (in mice and other lab animals) that suggest that exposure to these endocrine-disrupting chemicals, many of which are increasing in use, are contributing to female reproductive conditions,” said Dr. Leonardo Trasande, associate professor of pediatrics at New York University School of Medicine.
Trasande carried out the earlier study on the economic impact of these chemicals and is the lead author of the new study, published on Tuesday in the Journal of Clinical Endocrinology & Metabolism.
DDE is a breakdown product of the insecticide DDT that, although banned in the United States in 1972 and in Europe starting in the 1970s, still lingers in the environment and enters our body through food. The main exposure to phthalates is through eating food and drink stored in plastic containers that have phthalates.
Trasande and his colleagues determined that 56,700 cases of fibroids among women in Europe were probably due to DDE exposure, and 145,000 cases of endometriosis were probably caused by phthalates. The researchers arrived at these estimates through studies that looked at typical DDE exposures in women of reproductive age in Europe and the association between DDE levels in the blood and fibroid diagnoses.
In a similar way, they relied on a study that linked higher phthalate levels in women who had been diagnosed with endometriosis compared to healthy women.

Calculating the economic toll

The researchers estimated the economic burden of these extra cases of fibroids and endometriosis based on the typical cost of treating these conditions, such as by surgery, in European countries. The cost for fibroids was 163 million euros, or $183 million, while endometriosis cases racked up a bill of 1.25 billion euros, or $1.4 billion.
However, as the researchers noted in the study, the costs would be even greater if they had factored in infertility associated with fibroids and endometriosis, and the other health problems those conditions can lead to. For example, endometriosis can increase the risk of cancer and autoimmune disorders.
“In so far as Europe is actively considering criteria for endocrine-disrupting chemicals and they are about to pursue action to limit exposure to chemicals in that category, this work is likely to be extremely important in shaping European policy,” Trasande said.
The European Union and the U.S. Food and Drug Administration have already banned the use of certain endocrine disruptors, such as BPA, in baby bottles, though research suggestsalternatives to BPA might not be safe.
Although the United States is not as far along in considering restrictions on these chemicals, it could get a jumpstart from European legislation.
“Potentially some of the progress in European activity could actually bring the key stakeholders, such as environmental public health groups and industry, to the table in considering U.S. legislation,” Trasande said.
A study by Trasande and his colleagues estimating the health and economic burden of endocrine disruptors on fibroids and other conditions among women in the United States is slated to be published this summer.

Reducing exposure to endocrine disruptors

The health burden — and healthcare cost — of endocrine-disrupting chemicals could far exceed what the current study captured looking at only two chemical groups. As Trasande and his colleagues point out in the study, several other chemicals, such as PCBs, or polychlorinated biphenyls, have been linked with female reproductive health problems.
Some of these chemicals, including PCBs and dioxins, have already been restricted through a treaty called the Stockholm Convention on Persistent Organic Pollutants, which went into effect in 2004, said Linda S. Birnbaum, director of the National Institute of Environmental Health Sciences and the National Toxicology Program.
The current study is important because it focused on chemicals that have not been restricted, and in the case of DDE — which persists in the environment — are not able to be restricted, Birnbaum said. However, she said she was surprised the researchers did not include an analysis of chemicals such as BPA, which has also been linked to endometriosis risk.

“This study is kind of a wake-up to say endocrine disruptors impact the female reproductive system, and we have some evidence they are associated with an increase in endometriosis and fibroids and it costs a lot of money,” Birnbaum said.
However, Birnbaum added that despite the research linking endocrine disruptors with these health problems, “studies are not great and are mostly in animals and experiments on cells (in Petri dishes).”
More studies need to be carried out to look at exposure to endocrine disruptors over a lifetime, from womb through adulthood, because the chemicals could be affecting people differently at different stages of their lives, Birnbaum said.
Although current thinking is that the chemicals are dangerous to girls in the womb because they affect their developing reproductive system, studies have not been done to address this possibility.
Even with all the questions that remain, and few regulations in place, “there are safe and simple steps that families and women can take to reduce exposure to endocrine-disrupting chemicals,” Trasande said.
“They can eat organic, reduce canned food consumption, which reduces exposure to BPA, and avoid packaged or highly processed food, which is a major route for phthalates to enter food. They can also open windows to allow chemical dust, which accumulates on the carpet and electronics, to circulate out of homes.”

Alert! Research Links Fluoridated Water to ADHD

Fluoride, a questionable chemical added to drinking water and toothpaste for the oft-repeated goal of preventing tooth decay, may actually be responsible for certain childhood mental disorders, according to new study Neurobehavioural effects of developmental toxicity from the Harvard School of Public Health. The researchers looked at various chemicals that children are regularly exposed to and found that several, including fluoride, are directly related to attention deficit hyperactivity disorder (ADHD) and other mental issues.

The typical cigarette filter is made of glass “wool” fibers that cut your lungs to shreds over time

Image: The typical cigarette filter is made of glass “wool” fibers that cut your lungs to shreds over time

Why do you think the cigarette filters or “butts” that you find on the ground outside take up to 15 years to disintegrate? Do you know why? That’s not just some sponge wrapped tightly in paper, no, that little heat screen is made from glass wool that is VERY SIMILAR to the fiberglass insulation used for your attic. Ever get that stuff on your skin?

Imagine what these fibers do to the epithelial (soft) tissues inside the lungs. MDs don’t talk about the pool of glass shards at the bottom of your lungs that looks like a ground up glass pile–when they light up those x-ray boards, now do they? We here at don’t wonder why. We KNOW why. The reason these fibers are used in a cigarette filter is because they keep your fingers cool so you can suck back all that nicotine, good ’til the last drop.

It’s the ultimate nicotine delivery addiction machine–that little bleached white cancer stick engineered with ammonia-cooked nicotine so juiced up it HITS the BRAIN and HEART within three seconds, coming in as a vapor and the third most addictive DRUG on planet earth.

Fiber glass shards shred your lung tissue, fueling emphysema and chronic congestion

Chronic obstructive pulmonary disease (COPD) is the same thing as chronic obstructive lung disease or “airway” disease or chronic bronchitis–heck–they’ve got all kinds of names for when tiny shards of glass rip apart your membrane, then get charred with toxic chemicals, including insecticide and herbicide weed-killer, and then stick to the scar tissue inside little tar sacs that contribute to poor airflow, which worsens over time and includes shortness of breath, extreme coughing “hack” fits and SPUTUM production.

Even Yahoo “answers” admits the fact that all cigarettes made today that have filters have fiberglass in them. Oops: here’s that:

tiny shards of glass

tiny shards of glass packed tight

Fiberglass insulation is what insulates most attics and keeps them warm in the winter and cool in the summer. It’s made by grouping millions of tiny glass fibers, which are tiny rods of glass nearly too small to see individually, like glass wool. There is a reason why cigarette filters (butts) take up to fifteen years to disintegrate. They are made of glass wool, and that is why a smoker’s fingers and/or thumb stay cool, even when they smoke the cigarette right down to the nub/filter.

When these tiny “shards of glass” escape into the mouth, throat, esophagus and lungs, they rip apart the epithelial tissue, the soft tissue lining the inside of those parts of the body. This creates damage not only on the surface but on the cellular level. Then the chemicals creep into the wounds, and that leads to cancer.

Notice part 12 stretched out in the diagram below:

cig parts map

When viewing X-rays of people exposed to asbestos or fiberglass, and even smokers lungs, ground glass opacity (glass fibers sitting in lungs) looks as if someone breathed in glass fibers and a pile of them are just sitting at the bottom of the lungs, like ground glass in a busted light bulb. Can this be filtered out of the lungs, ever? Can a person detoxify themselves from ground glass “syndrome”? (

Here’s what a COPD lung slab looks like after being ripped apart by glass wool and tar-n-feathered with chemicals, ammonia, bleach and formaldehyde from the cigarettes:

CDC refuses to surrender incriminating documents linking MMR vaccines to autism

Image: CDC refuses to surrender incriminating documents linking MMR vaccines to autism

Everyone (or, at least, everyone not blinded by the government’s propaganda) probably knows the scandal by now: Despite the fact that the Centers for Disease Control and Prevention’s (CDC) own research discovered that MMR vaccines caused autism among African American children, the agency chose to bury the evidence to hide it from public scrutiny.

This scientific conspiracy involved even the CDC’s top honchos, including Dr. Julie Gerberding — former CDC director, and now Merck executive.

CDC refuses to release evidence to Congress

Despite all the evidence and testimonies pointing to the fact that there was, indeed, a huge cover-up, the CDC still refuses to surrender the relevant documents to the U.S. Congress. Congressman Bill Posey (8th District, Florida) requested certain documents from the CDC in a congressional hearing, but the CDC failed to budge.

“The CDC can’t be trusted regarding investigating vaccine safety,” Posey said. “Huge conflict of interest. I think the CDC should be investigated.”

What’s abundantly clear to everyone is the fact that the CDC is operating what can only be called a “criminal racket” that’s rife with scientific fraud, a major purpose of which is to hide the truth about MMR vaccines. In 2002, the CDC possessed evidence showing that MMR vaccines increase the risk of autism in African American babies by 340%, yet instead of warning the public, the agency’s top scientists and executives actively conspired to bury, and even destroy, that evidence. Now that Congressman Posey is attempting to get some answers, the CDC is also stonewalling his office. In the quest for truth, Mike Adams, the Health Ranger, contacted Posey’s office to obtain some clarifications regarding the matter. Posey’s media contact relayed the following statement coming from the congressman himself: “When it comes to our children, we must make sure that any intervention is as safe as possible, including vaccinations. Scientific integrity is a key component to giving that assurance. I will continue to press for a full understanding of the evidence in this situation. The CDC has refused for more than six months to hand over documents I requested concerning this issue. That is not the type of response we expect from our government.”

When asked for further clarification, Congressman Posey’s spokesperson explained, “We want to see the truth come out, and ultimately we want to see proper studies done so families can have assurances… and so the public knows the proper course of action regarding vaccinating their children.”

The CDC, of course, absolutely does not want the truth to come out.

Mainstream media covers up for the CDC

In a bid to protect its interests, the CDC has even conspired with the mainstream media (what’s new?) to censor the story. How many headlines or news stories blasting the CDC have you seen? This case is obviously such a huge scandal in the community, yet there’s little to no mainstream media coverage on it at all.

Fortunately, it doesn’t matter if The New York Times or The Washington Post covers up the whole issue. Concerned citizens now have the “truth media” to thank for no-holds-barred commentaries on today’s most pressing issues.

Truth seekers out there, remember: Don’t be fooled by government and mainstream media propaganda. Not all hope is lost, because the alternative media will always find a way to bring out the truth.

Airlander 10: Meet the World’s Largest Aircraft

New photographs of the world’s longest aircraft were made public yesterday ahead of its official unveiling and first UK test flight. They show the Airlander 10 — part plane, part airship and part helicopter. The aircraft is 302ft (92m) long, which is about 60ft (18m) longer than the biggest airliners. The British firm Hybrid Air vehicles (HAV) have designed the craft to stay airborne for up to three weeks using helium and the vessel is able to travel at a speed of 92mph.

Airlander 10: Meet the World’s Largest Aircraft

HAV will unveil the Airlander 10, standing at 26m high and 44m wide, in a First World War aircraft hangar in Bedfordshire today and it will undergo its first test flight in a few weeks’ time. It was first developed in 2009 for the US government as a long-endurance surveillance aircraft but its manufacture was hindered by defence cut-backs. HAV says the vessel, which is silent and emits no pollution, could be the future for air travel.

HAV believe the airship, which cost £25m to build, could be used for a host of functions including surveillance, communications, delivering aid and even passenger travel. It is hoped the Airlander 10 will eventually be developed to be able to transport 50 tonnes of freight. As it is heavier than air, the aircraft is able to land without tethers on a variety of surfaces, including water and ice. The firm is hoping to build 12 Airlanders a year by 2018, some as passenger aircraft that will carry up to 48 people at a time.

Chris Daniels, Head of Partnerships at HAV, said: “We will not compete with a 747 flying across the Atlantic, but we can offer the ultimate flight experience for tourism and leisure purposes. “It’s perfect for sightseeing because we can have floor to ceiling clear panels, and we can open the windows because we are not flying as high or as fast as traditional planes, but we will not be offering a service to get from A to B as quickly as possible.”

Researcher improves crop performance with new biotechnology

ASU researcher improves crop performance with new biotechnology
Researchers with ASU School of Life Sciences discovered a way to enhance a plant’s tolerance to stress, which in turn improves how it uses water and nutrients from the soil. These improvements increase plant biomass and yield. This discovery could be instrumental in agriculture and food security by improving crop sustainability and performance. By increasing the expression of the enzyme H+PPase, plants can more effectively move sugar, water and nutrients to the places they need them to grow better roots, fruits, seeds and young leaves. 

With the world’s population exploding to well over 7 billion, feeding the human race is getting even more challenging. Increasing the yield from crops such as wheat, maize, rice and barley, is paramount to growing enough food.

In addition, is now affected by stressors such as drought, climate change and the salinization of fields—presenting obstacles to our future food supply.

Researchers with Arizona State University’s School of Life Sciences, University of Arizona, University of North Texas and with the USDA/ARS Children’s Nutrition Research Center, Baylor College of Medicine, have discovered a way to enhance a plant’s tolerance to stress, which in turn improves how it uses water and nutrients from the soil. These improvements increase plant biomass and yield.

The study’s findings are published in the scientific journal Trends in Biotechnology.

Associate professor Roberto Gaxiola with ASU School of Life Sciences said this discovery could be instrumental in agriculture and food security by improving crop sustainability and performance.

“‘We have learned how to modify the expression of a gene that codes for a plant proton pump,” said Gaxiola, lead author of the study. “This gene helps to move photosynthates—or molecules made by photosynthesis in the leaves—to the places plants need them in order to grow better roots, fruits, young leaves and seeds. This gene is called type 1 H+-PPase and is found naturally in all plants.”

Current agricultural methods often overuse fertilizer, causing environmental problems by polluting water with phosphates and creating dead zones in oceans downstream. Over-fertilization can also cause plants to have small roots—something that was not anticipated when fertilizers were developed in the early 1900s.

By changing how effectively a plant uses water and nutrients, famers would be able to use fewer resources to grow their crops.

“Larger roots allow plants to more efficiently acquire both nutrients and water. We can optimize inputs while minimizing environmental impacts. This is advantageous for our environment and for all consumers,” said Gaxiola.

Altering the expression of this gene in rice, corn, barley, wheat, tomato, lettuce, cotton and finger millet caused better growth in roots and shoots, and also improve how the plants absorbed nutrients. These crops also saw improved water use and tolerance to salt. In finger millet, researchers also discovered an increase in antioxidants, but further studies would be needed to know whether this is the case with other crops as well.

Gaxiola suggested the next step is to further study this simple biotechnology in order to maximize its agricultural potential.


Scientists observe self-impregnating female fish

According to a study by British researchers, a female Cichlid hybrid fish was observed to have grown male reproductive organs and impregnated itself. Researchers called the process ‘selfing’ and suggested that it is rare in vertebrates. It was revealed that the fish discharged sperm into the water and sucked it back into its mouth to fertilize the eggs present there.

female cichlid hybrid fish has been observed to have grown male reproductive organs, impregnate itself and then to have offspring, a team of researchers in the U.K. are reporting in a paper published in the journal Royal Society Open Science. They call the process ‘selfing’ and suggest it is very rare in vertebrates

The team reports that they were studying chichlid and at one point bred two different species of the fish, resulting in the of several offspring, only one of which later developed . Such fish, they note reproduce by mixing sperm and egg sin the mouth. In this instance, it appeared that the hybrid ejected sperm into the water and then sucked it into its mouth where it fertilized the eggs that were waiting there. The fish shortly thereafter gave birth to several offspring. Also, the team reports, it was not a onetime occurrence, the fish self fertilized itself many times over the course of a year, giving birth to 42 offspring (both male and female) of which it was both the mother and father. The all appeared normal and reproduced without any of them resorting to selfing. They did all suffer, however, from what scientists call inbreeding depression, where there is minimal , which can lead to birth defects in subsequent generations. Having two genders it is believed was an evolutionary development that came about to allow for genetic diversity, after all.

Selfing is not unheard of in the animal kingdom, other species such as mangrove killifish engage in it as part of their normal reproductive habits—but in their case, it is one born of necessity when there are no potential mates around—it is also an adaption that came about out of necessity. The researchers believe the selfing observed in the cichlid female likely came about due to its parents having different sex-determining genes, and that it was almost certainly an oddity, and thus not likely to happen again anytime soon. They note also that it is not likely that this was the first occurrence of selfig in the species, such instances have likely gone underreported due to its rarity.

Compared with other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes. Here we report observing one F1-hybrid individual that developed into a functional hermaphrodite after crossing two closely-related sexually reproducing species of cichlids. Microsatellite alleles segregated consistent with selfing and Mendelian inheritance and we could rule out different modes of parthenogenesis including automixis. We discuss why selfing is not more commonly observed in vertebrates in nature, and the role of hybridization in the evolution of novel traits.

Nonlinear rotational Doppler effect observed

In a first, University of Birmingham scientists have experimentally demonstrated the nonlinear rotational Doppler effect of light, which was first theorized in 1968. The theory points to the wavelength shift of light while passing through a rotating object. Notably, the Doppler effect is the change in frequency of a periodic wave for an observer when moving relative to the source.


Experimental physicist Prof. Thomas Zentgraf and his two colleagues from the University of Birmingham, Dr. Guixin Li and Prof. Shuang Zhang, have for the first time proved experimentally the nonlinear rotational Doppler effect of light—nearly 50 years after its theoretical prediction by the Dutch Nobel Laureate Nicolaas Bloembergen.

 Rotational Doppler Effect in Nonlinear Optics

The acoustic Doppler effect can be experienced day in the real world every: An ambulance siren sounds sharper closer to the emergency vehicle; when the vehicle pulls away, the siren sound descends. This is due to the change of wavelength of the sound waves, which are compressed or stretched during the movement of the sound source, thus changing its pitch. The effect applies to all kinds of waves, including light waves. Similarly, as a star moves away from Earth, its emitted light wave is stretched, creating the so-called red-shift, i.e. a longer wavelength of light.

Conversely, a light wave emitted from a star approaching Earth will be compressed, which causes a blue shift. In 1842, the Austrian physicist Christian Andreas Doppler predicted this in his paper “On the colored light of the double stars and certain other stars of heaven,” and presented this phenomenon to the Royal Bohemian Society of Sciences in Prague. Three years later, the Dutch physicist Christoph H. D. Buys-Ballot observed the acoustic Doppler effect in a spectacular experiment. He used the fastest transportation tool at that time—the railway. A musician was playing trumpet on a moving rail car while musicians standing next to the track listened to the tones he played. The displacement of the pitch in the tones they heard as the train passed by is equivalent to the predictions for Doppler’s color shift of light.

Today, the Doppler effect has made possible a number of technological achievements in fields such as speed measurement via traffic cameras, GPS, and the ultrasound measurement of blood flow velocity in the human body. In addition, the Doppler effect plays a key role in such important quantum phenomena as the broadening of spectral lines and the trapping and cooling of atoms with laser light.

In addition to the well-known Doppler effect for translational movements, there is also a rotational Doppler effect for rotary motion of objects. This effect leads to a shift of wavelength depending on the , and can be used in the measurement of rotational frequencies of air turbulence, molecules and astronomical objects.

In 1968, a few years after the invention of the laser, a new rotational Doppler effect was predicted by Nobel laureate Nicolaas Bloembergen for rotating objects under the high intensities of illumination of laser light—a nonlinear rotational Doppler effect. Nearly 50 years later, this effect was demonstrated for the first time in the laboratory.

“Due to the small wavelength shift for this non-linear effect, it is extremely difficult to observe it directly in an experiment,” explained Prof. Thomas Zentgraf. This is due to the low rotational speed of objects compared to the speed of light. This means that the wavelength shift of light as it passes through a rotating object is in the range of a few trillionths of the wavelength itself. Even in the laboratory, such a small wavelength shift cannot be measured directly. “We have used a special superposition between two light waves, called interference,” explains Prof. Zentgraf. The change of this superposition was detected; from this, the wavelength shift was determined.

This poof of a fundamental effect of physics represents an important step in the examination of current theories. With the experiments at the University of Paderborn and the University of Birmingham, one further prediction has now been confirmed. In the future, this effect could find broad application in the study of turbulence, laser plasmas and the rotational property of molecules.
