Some E. coli Strains May Be Linked to Development of Bowel Cancer

According to a new study in the journal Nature, E. coli infections may be linked to bowel cancer. Some species of the intestinal microbiota, which is the collection of bacteria and viruses that live in the human gut, have been associated with colorectal cancer, but a direct role hasn't been proven. As it turns out, E. coli bacteria carry what is called a pathogenicity island pks, that creates enzymes that synthesize a compound called colibactin. Colibactin causes double-strand breaks in cultured cells. This damage can lead to cancer over time. Colibactin is found more often in fecal samples of people who do have bowel cancer than healthy people. Scientists don't know how many cases of bowel cancer may be linked to the E. coli bacteria, but estimate that as many as 5% of these … [Read more...]

Research Shows Possible Link Between E. coli and Cancer

A new study from the University of Minnesota School of Public Health and Masonic Cancer Center, published in the journal Science, finds a possible association between E. coli and cancer. The scientists have determined how toxins produced by the pathogen interact with and damage DNA on the molecular level. Applications from this study may help doctors understand how toxins affect DNA, and may help them to develop tools to improve chemotherapy treatments. The main researchers are Silvia Balbo, School of Public Health assistant professor, and Peter Villalta, mass spectrometry services coordinator at Masonic Cancer Center. Support was provided by the National Institutes of Health and the National Cancer Institute. The method uses mass spectrometry to study how toxins interact with … [Read more...]

CSPI Wants Cancer Warning Label on Processed Meat

The Center for Science in the Public Interest (CSPI) is calling on the USDA to put a warning label on processed meat and poultry products telling consumers that eating those foods is associated with an increased risk of colorectal cancer. bacon, ham, hot dogs, and other processed products would have that label. The regulatory petition CSPI filed yesterday cites the findings of the International Agency for Research on Cancer, which found in 2015 that processed meat is "carcinogenic to humans." The study found that eating 50 grams per day of processed meat raises the risk of developing that particular kind of cancer by about 18%. A typical serving size of those meats is about 55 grams. Colorectal cancer is the second leading cause of cancer deaths in this country. It will cause … [Read more...]

Use High Heat to Cook Meat? Rethink That Technique

A new study published in the journal Cancer has found that cooking beef at high temperatures may lead to an increased risk of developing kidney cancer. Carcinogenic compounds are created in the meat when grilled, barbecued, and pan-fried. The study was conducted at the University of Texas MD Anderson Cancer Center. Renal cell carcinoma affects 60,000 new patients every year. About 14,000 people die of this illness every year in the Untied States. The incidence of this type of cancer has been increasing for decades. Dr. Stephanie Melkonian, Epidemiology postdoctoral fellow and lead author of the study said, "this study encourages us to look not only at what foods we're eating, but also how we're preparing those foods." When you cook meat with high temperature, causing charring on the … [Read more...]

WHO Finds Glyphosate “Probably Carcinogenic”

In March, scientists organized by the World Health Organization (WHO) found that the herbicide glyphosate, which is an active ingredient in Round-Up, is "probably carcinogenic to humans." Food and Water Watch, along with the Washington Office on Latin America (WOLA) are calling for an end to the U.S. backed program that sprays glyphosate on coca fields in Columbia. Adam Isaacson, senior associate for regional security policy at WOLA¬†said, "there is now proof that the sprayings of glyphosate represent an unacceptable risk to the public. This has critical implications for a program that has been a cornerstone of U.S. drug policy in Colombia." The herbicide has been sprayed over more than 4 million acres in that country over the past 20 years. Glyphosate was considered safe for humans … [Read more...]

Early BPA Exposure Increases Prostate Cancer Risk

Food Poisoning Bulletin has been covering the story of bisphenol A (BPA), a chemical used to harden plastics, for years. Health risks associated with this chemical have been well known for some time. In fact, because of consumer pressure, all manufacturers of baby bottles have removed the chemical from their products. The FDA belatedly finalized a rule banning BPA in infant formula packaging last summer. A new study in the Journal of Endocrinology, published today, finds that BPA exposure early in life increase the risk of prostate cancer. Unfortunately, BPA is found "universally" in the umbilical cord blood of pregnant women, according to a study conducted in California last August. In the latest study, mice were implanted with human prostate stem cells from healthy males. The mice … [Read more...]

CSPI Downgrades Splenda from “Safe” to “Caution”

The Center for Science in the Public Interest (CSPI) is downgrading sucralose, which is the artificial sweetener commonly known as Splenda, from the "safe" category to "caution" after an unpublished Italian study found the chemical caused leukemia in mice. This is the same independent lab that found aspartame caused cancers in mice and rats. All previous long-term feeding studies of sucralose conducted on animals were performed by the chemical's manufacturers. UPDATE: CSPI has now downgraded Splenda from "Caution" to "Avoid." Unlike other artificial sweeteners, sucralose can be used in baking, since the compound doesn't break down at high temperatures. CSPI objected to sucralose from the beginning. In 2008, a study funded by the sugar industry found that Splenda reduces beneficial … [Read more...]

Ingredient in Roundup Weed Killer Found in Food

A peer-reviewed study from the Massachusetts Institute of Technology (MIT), published in Entropy, has found that residues of glyphosate, the main ingredient in the weed killer Roundup, have been found in food. Glyphosate is used on crops that are genetically engineered (GMO foods) to be "Roundup Ready". Monsanto scientists have claimed for years that Roundup is safe and non-toxic because it targets the shikimate pathway in plants, which is absent in animals. But this pathway is present in bacteria that live in human guts, which play an important role in human physiology, from immunity to synthesizing vitamins. The study's authors say that glyphosate does induce disease and is a "textbook example of exogenous semiotic entropy." Glyphosate inhibits detoxification of xenobiotics and … [Read more...]

Ginko Biloba Linked to Cancer in New Study

The dietary supplement Ginko biloba, which some believe helps improve memory (although studies have shown it is ineffective), has been linked to cancer in ratrs and mice. The new study, conducted by scientists at the National Toxicology Program (NTP), found that animals who received the supplement were more likely to develop tumors in the liver and thyroid than animals who were not given the extract. In the study, scientists gave 50 male and female rats corn oil solutions with 100, 300, or 1,000 milligrams of Gingko biloba extract per kilogram of body weight five times a week for two years. Another group received 200, 600, or 2000 mg/kg every day. Those concentrations fall within the range of what is on the market. The supplier of the extract does supply material to companies in the … [Read more...]

Eating Deep Fried Foods Increases Risk of Prostate Cancer

Research published in The Prostate has found that eating deep fried foods regularly is linked to an increased risk of developing prostate cancer. In addition, more aggressive types of the disease are more likely when deep-fried foods are part of a diet. The study was conducted at the Fred Hutchinson Cancer Research Center. The scientists studied 1,549 men who had been diagnosed with prostate cancer and compared them with 1,492 age-matched men who were healthy. They controlled for age, family history of the disease, PSA screening history, and BMI. Dr. Janet L. Stanford, lead author of the study, said, "to the best of our knowledge, this is the first study to look at the association between intake of deep-fried food and the risk of prostate cancer." The problem is most likely … [Read more...]
