And you thought processed foods were checked for cancer causing chemicals ?
By Dr. Alan Kadish NMD
Although it seems repetitive here is another good reason to ditch the processed foods and move forward with a more natural approach to foods. In this study done at Georgia State, two of the common food emulsifiers used in a ton of foods have been found to be associated with cancer, obesity and bowel disease, when tested in mice.
The short story; the two emulsifiers, polysorbate 80 and carboxymethylcellulose influence the bacterial families in our guts which cause a change in our immune system leading to inflammation that over times can cause cancer, in the susceptible group and the other disorders in all of the groups.
The author’s conclusions are alarming. “The team notes that the results of their study suggest that current means of testing and approving food additives may not be adequate to prevent the use of chemicals that promote diseases…”. Certainly not what you want to hear.
So where would you encounter these common food additives ? Think many foods with a smooth texture or those with the need to mix oil and water components such as: puddings, ice cream, dressing, cheese, icing, toppings, gelatinous desserts, infant/baby formula,(yes you read that correctly), candy, , bar B Q sauces, whipped dressings and even some cheeses and cheese spreads. By the way, have you checked your cheap and not so inexpensive vitamins ?
The take-away is to eat real food, not processed stuff. Check the labels on what you consume and avoid the emulsifiers when possible. Want to know more or get a good look at your health ? Call us at the Center of Health 541.773.3191
Widely Used Food Additive Promotes Colitis, Obesity, and Metabolic Syndrome, Research Shows
FEBRUARY 26, 2015
ATLANTA—Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome, new research shows.
The research, published Feb. 25 in Nature, was led by Georgia State University Institute for Biomedical Sciences’ researchers Drs. Benoit Chassaing and Andrew T. Gewirtz, and included contributions from Emory University, Cornell University and Bar-Ilan University in Israel.
Inflammatory bowel disease (IBD), which includes Crohn’s disease and ulcerative colitis, afflicts millions of people and is often severe and debilitating. Metabolic syndrome is a group of very common obesity-related disorders that can lead to type-2 diabetes, cardiovascular and/or liver diseases. Incidence of IBD and metabolic syndrome has been markedly increasing since the mid-20th century.
The term “gut microbiota” refers to the diverse population of 100 trillion bacteria that inhabit the intestinal tract. Gut microbiota are disturbed in IBD and metabolic syndrome. Chassaing and Gewirtz’s findings suggest emulsifiers might be partially responsible for this disturbance and the increased incidence of these diseases.
“A key feature of these modern plagues is alteration of the gut microbiota in a manner that promotes inflammation,” says Gewirtz.
“The dramatic increase in these diseases has occurred despite consistent human genetics, suggesting a pivotal role for an environmental factor,” says Chassaing. “Food interacts intimately with the microbiota so we considered what modern additions to the food supply might possibly make gut bacteria more pro-inflammatory.”
Addition of emulsifiers to food seemed to fit the time frame and had been shown to promote bacterial translocation across epithelial cells. Chassaing and Gewirtz hypothesized that emulsifiers might affect the gut microbiota to promote these inflammatory diseases and designed experiments in mice to test this possibility.
The team fed mice two very commonly used emulsifiers, polysorbate 80 and carboxymethylcellulsose, at doses seeking to model the broad consumption of the numerous emulsifiers that are incorporated into almost all processed foods. They observed that emulsifier consumption changed the species composition of the gut microbiota and did so in a manner that made it more pro-inflammatory. The altered microbiota had enhanced capacity to digest and infiltrate the dense mucus layer that lines the intestine, which is normally, largely devoid of bacteria. Alterations in bacterial species resulted in bacteria expressing more flagellin and lipopolysaccharide, which can activate pro-inflammatory gene expression by the immune system.
Such changes in bacteria triggered chronic colitis in mice genetically prone to this disorder, due to abnormal immune systems. In contrast, in mice with normal immune systems, emulsifiers induced low-grade or mild intestinal inflammation and metabolic syndrome, characterized by increased levels of food consumption, obesity, hyperglycemia and insulin resistance.
The effects of emulsifier consumption were eliminated in germ-free mice, which lack a microbiota. Transplant of microbiota from emulsifiers-treated mice to germ-free mice was sufficient to transfer some parameters of low-grade inflammation and metabolic syndrome, indicating a central role for the microbiota in mediating the adverse effect of emulsifiers.
The team is now testing additional emulsifiers and designing experiments to investigate how emulsifiers affect humans. If similar results are obtained, it would indicate a role for this class of food additive in driving the epidemic of obesity, its inter-related consequences and a range of diseases associated with chronic gut inflammation.
While detailed mechanisms underlying the effect of emulsifiers on metabolism remain under study, the team points out that avoiding excess food consumption is of paramount importance.
“We do not disagree with the commonly held assumption that over-eating is a central cause of obesity and metabolic syndrome,” Gewirtz says. “Rather, our findings reinforce the concept suggested by earlier work that low-grade inflammation resulting from an altered microbiota can be an underlying cause of excess eating.”
The team notes that the results of their study suggest that current means of testing and approving food additives may not be adequate to prevent use of chemicals that promote diseases driven by low-grade inflammation and/or which will cause disease primarily in susceptible hosts.
This study was funded by the National Institutes of Health and Crohn’s & Colitis Foundation of America.
