    Health ALERT: Titanium dioxide in our food supply increases the risk of cancer and dementia, scientists report

    by: Lori Alton, staff writer | June 12, 2019

    Titanium dioxide, a common food additive, has traditionally been viewed as an ‘inert and safe’ substance. But the widespread use of E171 – titanium dioxide nanoparticles – has added a scary new wrinkle.

    A recent, headline-making Australian study shows that E171 can affect the balance of gut bacteria – promoting inflammation and setting the stage for conditions such as intestinal bowel disease (IBD) and colon cancer.

    This is particularly disturbing news, as manufacturers use E171 abundantly as a whitening agent in processed foods, personal care products and medicines. In fact, close to a thousand popular products – from powdered doughnuts to breath mints to sunscreen – contain E171.

    Warning about titanium dioxide in our food supply and the risk of cancer

    Titanium dioxide nanoparticles – also called ultrafine titanium dioxide or nanocrystalline titanium dioxide – typically have diameters measuring under 100 nanometers. And, just to give an idea of their infinitesimal size, a single nanometer is one million times smaller than a millimeter.

    These nanoparticles are capable of penetrating cells and interfering with cell mechanisms – and can even make it to cell nuclei – where they directly interfere with the structure and function of DNA.

    E171 is, by far, the most common of the titanium dioxide-containing materials. And, it’s a very persistent substance in the environment.

    Did you know? The liver is the most important detoxifying organ in the body. When the liver can’t effectively neutralize and dispose of toxins, they accumulate in the body. Two essential nutrients for healthy liver function are milk thistle and glutathione. These two ingredients - plus much more – are now available in an advanced liver support formula. Click here to learn more.

    Research has shown that E171 can enter rivers and streams as treated effluent from wastewater treatment plants – a matter that raises concern from natural health experts and environmentalists.

    By the way, the International Agency for Research on Cancer has already classified titanium dioxide as a possible carcinogen. And, there’s more bad news about titanium dioxide nanoparticles.

    According to a scholarly review published in 2012 in Environmental Science and Technology, titanium dioxide exposure from consumption of foods and medicines has been linked to Crohn’s disease.

    Other diseases linked to exposure to nanoparticles include cancer, dementia, autoimmune conditions, eczema, asthma and autism.

    Plus, here’s an infuriating fact:

    While the use of titanium dioxide nanoparticles has soared over the last decade, only a limited number of products actually list them as ingredients.

    In fact, the U.S. Food and Drug Administration (FDA) says that manufacturers can use up to 1 percent food-grade titanium dioxide – without declaring it on labels.

    Study says: E171 triggers inflammation, cancer and IBD

    In an animal study conducted at the University of Sydney and published in Frontiers in Nutrition, researchers found that consumption of food containing E171 affects the trillions of bacteria that constitute the gut microbiome (the community of microbes which plays an indispensable role in immune health).

    This interference, noted the team, could potentially set the stage for inflammation, cancer and intestinal disease.

    “Gut flora community is a ‘gate-keeper’ of our health,” commented a study co-leader, “so any changes can impact overall health.”

    Although E171 didn’t change the composition of the bacteria, it affected their activity, promoting the growth of harmful biofilms (layers of adhesive, difficult-to-dislodge bacteria).

    The formation of biofilms has been reported in diseases such as colorectal cancer, noted study co-author Professor Laurence Macia, an immunologist and expert on the impact of gut microbiota on health.

    The gut microbiome has a powerful impact on physical and emotional health
    Research has shown that the balance between “friendly” and pathogenic (disease-causing) bacteria can affect immunity, brain health and even emotional well-being.

    And, let’s not forget, about 70 – 80 percent of the immune system is actually located in the gut.

    In addition, the microbiome is vital in breaking down and absorbing nutrients from food, and also assists with the production of neurotransmitters, the brain’s “chemical messengers.”

    Experts say that disturbances in the proper balance of gut bacteria – a state also known as dysbiosis – are associated with Parkinson’s disease, IBD, obesity, heart disease and diabetes.

    Conversely, there is some evidence that regulating and balancing the microbiome can lead to improvements in mood and emotional state. In fact, there is exciting news on that front, courtesy of just-published research in General Psychiatry.

    After conducting a review of 21 studies involving over 1500 participants, the authors concluded that people who experience anxiety symptoms could be helped by regulating gut flora.

    The team examined the use of both probiotic and non-probiotic methods – including foods, supplements and adjustments to daily diet – and concluded that regulating gut flora helped to regulate brain function.

    Overall, over half the studies were found to show a positive effect on anxiety symptoms.

    Interestingly, the non-probiotic methods of regulating gut flora were more successful than supplementation with probiotics. The team noted that dietary changes could have more of an effect on gut bacterial growth than introducing specific strains in a supplement – and called for more study.

    Warning: E171 can threaten brain health

    Studies have shown that E171 may affect more than just the gut microbiome. Titanium dioxide nanoparticles have been shown to have damaging effects on the survival and function of brain cells.

    Specifically, nanoparticles were found to harm astrocyte cells, which regulate the neurotransmitters – such as serotonin and dopamine – needed for stable mood, proper digestion and restful sleep.

    In one study, researchers found that astrocytes that were not killed outright were damaged in such a way that they became unable to absorb the neurotransmitter glutamate. This led to accumulation outside the cell – a phenomenon that has been implicated in both Alzheimer’s and Parkinson’s disease.

    And, an animal study published in Cancer Research showed that titanium dioxide nanoparticles could cause breaks in chromosomes, oxidative damage to DNA, and inflammation.

    Not only that – but researchers pointed out the harm occurred after only 5 days of administration of titanium dioxide in drinking water.

    So, how do you avoid these ubiquitous, tiny particles?

    While not all titanium dioxide used in food and medicine is in the form of ultramicroscopic nanoparticles, much of it is. So, avoiding processed foods is your first line of defense in minimizing exposure.

    It’s ironic that the very substances used to create clean-looking, snowy-white products can cause such an array of toxic effects. Clearly, titanium dioxide nanoparticles are “bad news” – in a very small package.

    Interesting.. I know when you make natural sunscreen with titanium dioxide, they say specifically to get "non-nano" titanium dioxide.

    Better lay off the powder sugar donuts and quit eating sunscreen.

    https://scienceandfooducla.wordpress...oxide-in-food/

    Titanium dioxide is marketed by DuPont as an inert chemical, meaning it shouldn’t react with other chemicals. Given the fact that powdered donuts include 100 mg per serving of titanium dioxide and the lethal dosage, measured as the LD50 or the amount needed for 50% of the population to perish from consuming the chemical, was measured in rats to be 5,000 mg/kg, A 200 lb human (90.7kg) would need to eat 4,535 powdered donuts and have a 50% chance of survival. (5000)X90.7= 453500 mg. Although it is impossible for a human to consume this many donuts at once, Dunkin Donuts recently stopped using titanium dioxide in their powdered sugar donuts after being pressured by the public to do so.

    Are larger grains of the substance passed through the body?

    The OP seems to indicate the ultra fine particles are the problem here.

    They found it only at over 50 micrograms per kg of weight for the rats in their experiment (they also looked at smaller amounts as low as two mg/ kg body weight).

    Given the fact that powdered donuts include 100 mg per serving of titanium dioxide
    (from my previous post and link).

    150 pound person is about 70 kg so they can eat 35 donuts a day and be OK according to their data. (a couple of assumptions: 1) rats digestive system is the same as humans and 2) all of the titanium oxide in donuts is the micro type). If you eat 35 donuts a day, you won't be 150 pounds for very long though.

    Titanium dioxide (TiO2) is considered as an inert and safe material and has been used in many applications for decades. However, with the development of nanotechnologies TiO2 nanoparticles, with numerous novel and useful properties, are increasingly manufactured and used. Therefore increased human and environmental exposure can be expected, which has put TiO2 nanoparticles under toxicological scrutiny. Mechanistic toxicological studies show that TiO2 nanoparticles predominantly cause adverse effects via induction of oxidative stress resulting in cell damage, genotoxicity, inflammation, immune response etc. The extent and type of damage strongly depends on physical and chemical characteristics of TiO2 nanoparticles, which govern their bioavailability and reactivity. Based on the experimental evidence from animal inhalation studies TiO2 nanoparticles are classified as “possible carcinogenic to humans” by the International Agency for Research on Cancer and as occupational carcinogen by the National Institute for Occupational Safety and Health. The studies on dermal exposure to TiO2 nanoparticles, which is in humans substantial through the use of sunscreens, generally indicate negligible transdermal penetration; however data are needed on long-term exposure and potential adverse effects of photo-oxidation products. Although TiO2 is permitted as an additive (E171) in food and pharmaceutical products we do not have reliable data on its absorption, distribution, excretion and toxicity on oral exposure. TiO2 may also enter environment, and while it exerts low acute toxicity to aquatic organisms, upon long-term exposure it induces a range of sub-lethal effects.

    Conclusions
    Until relevant toxicological and human exposure data that would enable reliable risk assessment are obtained, TiO2 nanoparticles should be used with great care.

    Is that nano-Titanium dioxide or titanium dioxide? Your quote just says titanium dioxide.

    Like I said, all the naturals out there like to use organic sunscreen with natural ingredients, including titanium dioxide. However, they warn specifically against using nano-titanium dioxide. Thus, you can find on amazon and ebay sellers of products called non-nano titanium dioxide, so their customers can be sure it is not nano-titanium dioxide.

    Donuts probably don't need the additional expense of producing and using nano particles. I would assume not nano. My source didn't say.

    https://phys.org/news/2015-03-dunkin...m-dioxide.html

    The titanium dioxide used by Dunkin' Brands and many other food producers is not a new material, and it's not really a "nanomaterial" either. Nanoparticles are typically smaller than 100 nanometers in diameter. Yet most of the particles in food grade titanium dioxide are larger than this. They have to be for the powder to be of any use in food products.

    Admittedly food grade titanium dioxide does contain a few nanoparticles, and this shouldn't be dismissed. A 2012 study out of Paul Westerhoff's lab at Arizona State University tested 89 off-the-shelf food products for the presence of titanium dioxide. The list included everything from gum and soy milk, to Twinkies and mayonnaise. As well as finding evidence for the substance in every product, the research also indicated that up to 5% of the titanium dioxide in some of these products could be in the form of nanoparticles.

    Yet there is little evidence that this small quantity of nanoparticles skews the safety of food grade titanium dioxide. In 2004 the European Food Safety Agency carried out a comprehensive safety review of the material. After considering the available evidence on the same materials that are currently being used in products like Dunkin' Donuts, the review panel concluded that there no evidence for safety concerns.

    Most research on titanium dioxide nanoparticles has been carried out on ones that are inhaled, not ones we eat. Yet nanoparticles in the gut are a very different proposition to those that are breathed in.

    Studies into the impacts of ingested nanoparticles are still in their infancy, and more research is definitely needed. Early indications are that the gastrointestinal tract is pretty good at handling small quantities of these fine particles. This stands to reason given the naturally occurring nanoparticles we inadvertently eat every day, from charred foods and soil residue on veggies and salad, to more esoteric products such as clay-baked potatoes. There's even evidence that nanoparticles occur naturally inside the gastrointestinal tract.
    If five percent of the titanium oxide is nano you can eat 20 times as many donuts so now you can have up to 700 powdered sugar donuts a day.

    @dannno

    In 2008, a peer reviewed study found that nano anatase titanium dioxide in sunscreen was reacting with sunlight and breaking down the coating on steel roofing in a matter of weeks. This study was prompted by reports that coatings on roofs were breaking down in places where workers had inadvertently transferred sunscreen to roofs via skin contact. Researchers from the 2008 study found that this sunscreen ingredient increased the normal rate of sun damage to the roofs by 100 times. (note 2) The study raised serious concerns about the impact these ingredients may be having on our skin. In 2010, Italian scientists warned that anatase titanium dioxide is “capable of destroying virtually any organic matter.” (note 3)
