[NaturalNews] A recent study published in the Journal of Toxicology in Vitrohas found that, even at very low levels, Monsanto’s herbicide formula Roundup destroys testosterone and ultimately leads to male infertility. The findings add to the more than 25 other diseases known to be linked to Roundup, which include DNA damage, birth defects, liver dysfunction, and cancer.
For their study, Emilie Clair and her colleagues from the Universite de Caen Basse-Normandie Institute of Biology in France tested the effects of glyphosate, the active ingredient in Roundup, on testicular cells from rats. Ranging in dilution from one part per million (ppm) to 10,000 ppm, which accounts for varying exposure levels in real life situations, each of the tests revealed undeniable cell toxicity caused by Roundup.
Interestingly, the findings revealed that even at one ppm, Roundup was responsible for causing severe endocrine disruption that reduced testosterone levels by 35 percent. And a one ppm exposure level is considered to be extremely low, and much lower than typical exposure levels in everyday environmental situations.
At higher exposure levels, Roundup was shown to induce testicular cell death in a little as one hour, and typically no later than 48 hours after exposure. And this is only acute toxicity, as the study did not analyze the long-term effects of continual and repeated exposure to Roundup, which has already been shown to seep into rivers and groundwater supplies.
A similar study published in the journal Reproductive Toxicology back in 2007 found similar results. In vivo tests with Roundup revealed that the ducks exposed to Roundup exhibited “alterations in the structure of the testis and epididymal (a part of the male reproductive system) region as well as in the serum levels of testosterone and estradiol, with changes in the expression of androgen receptors restricted to the testis.”
So contrary to the claims made by Monsanto, there is truly no safe exposure level to Roundup. At typical exposure levels, it has been proven to destroy human cells and cause serious reproductive harm. And at trace levels, it has been proven to severely disrupt proper hormonal function and lead to low testosterone in men.
“Because it’s a systemic pesticide and sprayed in high doses, produce and fruit and nut trees often take up the poison into the parts of the food we eat,” writes Leah Zerbe in a recent Rodale News piece on Roundup. “Three easy ways to reduce your exposure? Eat organically grown foods … [a]dopt organic lawn care techniques in your yard, and start an organic garden to further reduce your exposure to harmful chemicals.”

[NaturalNews] Circumventing reliance on sugar is something akin to a national pastime as many individuals seek unique ways to lessen their daily intake. This sort of dependence sends food marketers into a frenzy resulting in numerous products boasting “sugar free” or “low calorie” on their labels. For decades, thishas generallybeen achieved through the use of artificial sweeteners; however, the safety of these products is finally gaining appropriate public attention. One interesting if somewhat confusing alternative – “sugar alcohol” – is now offered in an ever-increasing number of products. It warrants a closer look.
What exactly is sugar alcohol?
Truly a misnomer, this sweetener is neither sugar nor alcohol even though it does share the chemical structure of each. Sugar alcohol, also known as polyol, is created by adding hydrogen atoms to sugar. For example, in the case of sorbitol, one of the more widely used sugar alcohols, hydrogen is added to glucose.
Potential benefits and risks
Extracted from chemicals in plants such as berries and fruits, its sweetness is achieved using less calories. While this sounds like an excellent outcome, like all deals that sound too good to be true, a price eventually must be paid. In this particular instance, it is the body’s inability to absorb the sugar alcohol that results in a lower caloric count. The price is paid by your small intestines. Therefore, when the unabsorbed sugar alcohol passes through your intestinal tract it can result in a laxative effect, causing bloating, diarrhea or abdominal pain.
Common sugar alcohols
There are several sugar alcohols being used in products today, each of which should appear on the ingredient list of the specific food or drink. Contained within the list you most commonly will find one of the following, most of which end with the letters “ol”:
Hydrogenated glucose syrups (HGS)
Hydrogenated starch hydrolysis’s (HSH)
Not all sugar alcohols are created equal
Each sugar alcohol occupies a different place on a scale of tolerable to intolerable. For example, mannitol and sorbitol are known to be the worst offenders when it comes to gastric distress. They should be consumed with caution. At the other end of the spectrum is erythritol which can be absorbed in the small intestine and, therefore, does not cause a laxative effect.
The one sugar alcohol which appears to be the most promising appears to be xylitol. Several studies have demonstrated xylitol can positively affect tooth enamel and bone mineral density. This explains why you frequently see it being used in chewing gum. However, although useful in smaller quantities, overconsumption remains a problem.
On the other end of the scale, sorbitol poses a unique health challenge for diabetics. Our bodies are capable of converting glucose into sorbitol within the body. However, this conversion process is greatly accelerated in diabetics. Because the accumulation of sorbitol has a hard time exiting the body, it causes the cells to swell, thus increasing the risk of nerve, kidney, and blood vessel damage as well as the development of cataracts. For that reason, it would be advisable to avoid sorbitol if you are diabetic.
As always, if your food carries any sort of health claim, you should carefully scrutinize the ingredients contained therein. The bottom line is that even though sugar alcohols may be safer than other artificial sweeteners, you will still want to limit their consumption or avoid them altogether if you are prone to gastric distress.

[NaturalNews] People that have suffered a traumatic injury face an uphill battle as they attempt to regain their health and fight the risk of depression as a long term consequence of the event. British researchers from Queen Mary at the University of London have published the result of a study in the Journal of Neuroscience that explains how omega-3 fatty acids play a significant role in preventing and protecting nerves from injury. The research focused on peripheral nerve cells which transmit signals between the brain and the spinal cord to the rest of the body. Omega-3 fats from food sources including sardines, salmon, walnuts and flax seeds provide for decreased cell death from injury and may offer significant protection against future damage.
Current research indicates that our nerves do have a limited capacity to regenerate, but recovery is severely limited depending on the extent of the injury. Omega-3 fatty acids are essential for the body’s normal growth and development and have been well researched for their health benefits, largely focused on brain and heart health. The body is unable to manufacture its own Omega-3 fat supply, so it is necessary to obtain sufficient intake from foods such as oily fish, nuts and seeds or through supplementation.
Omega-3 fats help prevent nerve damage and assist the repair process
Researchers studied the effect of omega-3 fats on isolated mice nerve cells, known to parallel human nerve responses. They simulated nerve damage caused from an accident or injury by either stretching the cells or starving them of oxygen. Both types of damage can kill a significant portion of nerve cells, but enrichment with omega-3 fatty acids in cells gave them significant protection and decreased cell death.
The study also examined sciatic nerve damage in the mice. They found that a high level of omega-3 fatty acids helped mice to recover from sciatic nerve injury more quickly and more fully, and that their muscles were less likely to waste following nerve damage. The team leader, Dr. Adina Michael-Titus, Professor of Neuroscience concluded “Our previous research has shown that these fatty acids could have beneficial effects in a number of neurological conditions. This new study suggests that they could also have a role in treating peripheral nerve injuries.”
The findings from this research should come as no surprise to integrative health followers. The omega-3 fats EPA and DHA are essential building blocks to all cellular structures in the body and are particularly dominant in the brain and nervous system. A healthy supply of omega-3 fatty acids allows for natural cell repair and the effective chemical and electrical communications that are important to optimal nerve function. Consuming fatty fish three to four times a week or supplementing with molecularly distilled fish oil (1 to 2.4 grams total EPA/DHA) supports the nervous system and regeneration process after injury.

[NaturalNews] Curcumin, the active anti-inflammatory compound found in the Indian spice tumeric, has gained an impressive reputation in the fight against many deadly forms of cancer. New evidence released in the journal Cancer Research finds that the natural phenol can slow prostate tumor growth by blocking receptors used to propagate cell tissue growth.
Additional research published in the journal PLoS Onee xplains the precise mechanism exerted by curcumin molecules to target the amyloid fibrils associated with the unnatural progression of protein-like plaque tangles that are characteristic in Alzheimer’s disease patients. Adding curry spice to your healthy diet or supplementing daily with a standardized curcumin capsule will help win your individual war against cancerous proliferation and Alzheimer’s dementia.
Prostate cancer is one of the most common forms of the disease, with more than 250,000 diagnoses in the US each year. Any natural compound that targets the proliferation of prostate cancer cells would provide a significant remedy compared with the allopathic methods of radiation, surgery and chemical agents. To conduct the study, researchers subjected prostate cancer cells to hormone deprivation in the presence and absence of curcumin with ‘physiologically attainable’ doses.
Curcumin blocks prostate cell receptors to thwart cancer progression
The researchers found that curcumin blocked two genetic receptors necessary for prostate cancer advancement. These receptors have been shown is past studies to predict cancer incidence and rate of growth of existing tumors. They noted that the spice extract was “a potent inhibitor of both cell cycle and survival in prostate cancer cells.”
The lead study author, Dr. Karen Knudsen and her team found that other cancer cell lines multiply by a similar receptor mechanism and may also be inhibited by the curry compound. She commented that curcumin “also has implications beyond prostate cancer… in other malignancies, like breast cancer. In tumors where these play an important function, curcumin may prove to be a promising therapeutic agent.”
In a separate research body, scientists found that curcumin prolongs life and enhances activity of brain neurons, acting as a neuroprotective shield against Alzheimer’s disease advancement. The research team determined that curcumin acted to prevent the damaging accumulation of amyloid fibrils around the nerve synapse. Amyloid tangles are known to prevent normal electrical and chemical transmissions required to form memories and maintain cognition.
Scientific research models continue to extol the virtues of natural spice and herbal extracts such as curcumin to help prevent and treat many deadly diseases that kill countless millions each year. Incorporate curry spices as part of your healthy diet or include a daily supplement (250 mg to 500 mg standardized curcumin extract) to significantly lower cancer risk and support healthy brain function.

Adult stem cells (as opposed to embryonic stem cells, which are at the heart of the stem cell controversy) are a truly exciting part of the future of medicine, with seemingly limitless potential for anti-aging, arthritis and far more…
But the U.S. Food and Drug Administration (FDA) is attempting to regulate stem cell procedures at a Colorado clinic, stating that stem cells are drugs that fall under FDA jurisdiction.
Outrageously, the FDA is making this claim even though the stem cells being used in the procedure come from the patient’s own body, which means they are essentially claiming that they can regulate a part of your body.
What Makes Stem Cell Treatments so Exciting?
What makes stem cells so special is their potential to develop into many different cell types.
When a stem cell divides, it either becomes another type of cell, such as a muscle cell or cartilage, or it remains a stem cell.
Furthermore, these cells act as an internal repair system in many types of tissues, dividing a seemingly indefinite number of times to replenish other cells.
As you age, your stem cells diminish in quality and quantity, so just when you require strong stem cells the most, you’re becoming increasingly deficient. Hence your organs and tissues eventually wear out and need to be restored or replaced.
The procedure in question by the FDA is known as Regenexx-C™. It involves taking a sample of your blood and bone marrow, and using a centrifuge machine to separate out the stem cells. The cells are then cultured to create more cells before they are injected back into your body to help with tissue repair. It is the fact that the cells are cultured that the FDA has attacked, saying this makes them “unregulated drugs.”
As a result the clinic now only offers the procedure outside of the United States, whereas within U.S. borders they use a similar procedure that is done in one day and does not involve culturing. This, reportedly, is less effective because fewer stem cells are delivered to the injury site. As for the promise of stem cell treatments in treating osteoarthritis pain, the positive results appear to be significant, including:
- Increases in cartilage volume in joints
- Up to 75 percent pain reduction in osteoarthritis
- Avoidance of surgery among patients previously told they would require total knee replacement surgery
Can the FDA Regulate Your Own Stem Cells?
While it would seem impossible for the FDA to claim authority over cells that come from your own body, the FDA has used the culturing process to gain a foothold in their attempts to label stem cells as unregulated drugs. In what the Alliance for Natural Health has called an “outrageous power-grab,” the FDA has claimed that the stem cells used for the Regenexx-C™ procedure are subject to their regulation because they are cultured to increase their numbers.
Furthermore, they also claim the clinic is engaging in interstate commerce because some of the components for the procedure are shipped in from out of state. This, the FDA claims, also makes it subject to FDA approval (the FDA has used a similar interstate commerce strategy to crack down on raw milk). According to the FDA:i
“FDA cautions consumers to make sure that any stem cell treatment they are considering has been approved by FDA or is being studied under a clinical investigation that has been submitted to and allowed to proceed by FDA. FDA has approved only one stem cell product, Hemacord, a cord blood-derived product manufactured by the New York Blood Center and used for specified indications in patients with disorders affecting the body’s blood-forming system.”
Stem cell treatments likely represent one of the exciting promises for the future of medicine. If stems cells can be directed to turn into specific cell types, they could offer an ongoing source of replacement cells and tissues, and be used to treat diseases above and beyond arthritis and joint pain, including spinal cord injuries, Alzheimer’s disease, diabetes and stroke, just to name several.
There’s little risk of rejection when using your own adult stem cells and side effects appear to be minimal. The largest safety concern is the possibility that the cells could migrate from their injection site and possibly change into inappropriate cell types or grow excessively, leading to tumors. As stem cell treatment is still being developed, this concern needs to be researched further. Whether the FDA should be able to weigh in on the matter is another issue entirely, as again adult stem cells from your own body are your own property. As Alliance for Natural Health reported, it seems once again the FDA is seeking to regulate a product more for its own financial gain, and to protect the drug industry, than for public health. In court documents it’s stated:
“Moreover, interstate commerce is substantially affected because individuals traveling to Colorado to have the Regenexx procedure would ‘depress the market for out-of-state drugs that are approved by FDA.’“
Is the FDA Really Looking Out for Your Health?
The FDA has a sordid history of attacking natural products and procedures that threaten to interfere with big business, including pharmaceuticals, agriculture and more, while allowing obviously harmful products to remain on the market. Here are but a few examples:
- In December 2011, the FDA reneged on its plan to withdrawal approval of penicillin and tetracycline antibiotics intended for use in food-producing animal feed – a measure it had been planning since 1977.
- In September 2011, the FDA issued a proposed draft policy on dietary supplements that could effectively kill your right to purchase nearly all of your favorite natural vitamins and supplements; the proposed policy treats vitamins and other supplements as if they are drugs but many manufacturers will not be able to afford the FDA drug trial process. This could either force supplement companies out of business or make supplements so expensive you won’t be able to afford them.
- The FDA has been fighting a war against raw milk, which is really an unconstitutional assault on one of your most basic rights, i.e. your right to choose what you want to eat and drink; they have stated that Americans have “no absolute right to consume or feed children any particular food.”
- The FDA has long been the world’s number one supporter of mercury fillings (amalgams), despite the evidence showing the health hazards of mercury; after making repeated promises to make an announcement about dental amalgam by the end of 2011, they let the deadline pass by unmet.
- The FDA sent a warning letter to Diamond Food for making truthful, scientifically backed health claims about the health benefits of omega-3 fats in walnuts. Because the research cited health claims that omega-3 fats in walnuts may prevent or protect against disease, the FDA said walnuts would be considered “new drugs” and as such would require a new drug application to become FDA-approved.
Knowledge truly is power, so the more you know about the real motives behind the FDA approval process, the better you’ll be able to make informed health care decisions, especially if you’re looking for alternatives to drugs and surgery. The FDA has gone after vitamin C. They’ve gone after raw milk, supplements, cherries and walnuts. And now they’re going after your own cells in an effort to protect drug industry profits…
Stay tuned for more on this topic as the events unfold. The reality is that as people become more educated stem cell therapy and other forms of regenerative medicine are only going to continue to grow.

[NaturalNews] Colon cancer is the third leading cause of cancer deaths annually, a statistic that remains constant despite increased awareness of the deadly disease. Researchers from the Science and Technology Institute of Food and Nutrition in Spain have published the result of a study in the journal Molecular Nutrition & Food Research detailing the potent anti-carcinogenic effect of the natural chocolate compound, cocoa. Scientists determined for the first time that regular consumption of cocoa negates the inflammatory effect of digestive oxidative stress that results in intestinal complaints and is a precursor to the genesis of colon cancer. Cocoa is now considered a superfood as it has been shown to improve blood lipids and help prevent cardiovascular disease in past research. The result of this current study demonstrates that a daily dose of the compound can help prevent colon cancer progression.
Researchers studied rats that had been fed a cocoa-rich diet consisting of twelve percent cocoa, as compared to a control group that received the same diet with the chocolate compound enrichment. Both groups were exposed to a chemical known to induce colon cancer. Animals such as mice and rats have been used for decades to conduct this type of research because they exhibit a similar line of carcinogenesis that is comparable to humans.
Cocoa polyphenols from dark chocolate significantly lower colon cancer risk
The study leader, Dr. Maria Angeles Martin Arribas noted “Being exposed to different poisons in the diet like toxins, mutagens and pro-carcinogens, the intestinal mucus is very susceptible to pathologies…foods like cocoa, which is rich in polyphenols, seems to play an important role in protecting against disease.” After a period of eight weeks, the scientists were able to confirm the protective effect of cocoa polyphenols in protecting against this insidious form of digestive cancer.
The study results showed a marked decrease in the number of pre-malignant neoplastic crypts in the lining of the colon in the cocoa-treated group as compared to the control animals. Further, the researchers found a rise in antioxidant defenses in the supplemented rats and a decrease in oxidative stress biomarkers that are known to be protective against chemical exposure and the prevention of colorectal cancer.
The team concluded that the protective effect of the bioactive compounds in cocoa stopped cell-signaling pathways that typically promote cell proliferation and lead to tumor development. The treated animals also exhibited a much higher degree of apoptosis, or normal programmed cell death of potentially cancerous tissues. It is important to note that milk chocolate is not a good source of cocoa due to its low concentration of the polyphenol and high sugar content, known to promote cancer. Choose a dark chocolate with a minimum 70 percent cocoa content to significantly lower the risk associated with colorectal cancer.
