Nanotechnology in Food? WTF!

I don't usually post such alarmist headlines, but when I read the following sentence in Food Navigator USA, a business-to-business publication, my eyes nearly popped out of my head. The article in which it appears is about the emerging use of nanotechnology to create stronger flavors and colorings in food and to serve other functions in food development and production. Here's the offending sentence:

One of the major safety worries about nanotechnology has been the suggestion that such small particles could feasibly cross cellular membrane barriers, meaning that an ingredient that is currently GRAS (generally recognized as safe) could become dangerous if it is nano-sized.

My first thought: Nanotechnology?! By George, 2010 is the future!
My second thought: "Cross cellular membrane barriers"? WTF?!
Apparently, it is rather cheap and easy for food producers to get into nanotech, in contrast to genetic engineering, a surprising fact that leads me back to thought number one.
The unknown impacts of these micro-particles, however, leads toxicologist Dr. George Burdock of the Burdock Group to state that this technology has the potential to become "the new asbestos," which brings me back to thought number two.
Burdock says that food manufacturers are on the hook to test the safety of all the ingredients they use, even tiny ones. What we have to worry about is those companies that decide to put us all at risk by cutting corners. “Manufacturers have a moral and ethical responsibility to test," he said. "Eighty percent of people play by the rules but you still have the bottom feeders."
Dear, oh, dear. Friends, I fear 2010 is indeed the future. WTF?

Yes, nanotech has been in our food for several years now! That's why deli meat can be dangerous. Nanotech makes the shelf life longer.

Legally I can't post and entire article on this link, but there is some alarming info here: New Lab Findings Point To Silicone/Silica and High Density Polyethlyene Fibers Causing Morgellons Disease

Also: Health Freedom Threats: Codex, FDA, Vaccinations, GMOs :: HealthFreedomUSA.org

The government can not stop nanotechnology because they have no way to regulate it or monitor it. It is just too small to detect.

As I have said before, read the ingredients on food labels, stay away from foods with long shelf life (they contain preservatives that our bodies do not recognize), don't eat at fast food or chain restaurants, and try to buy organic foods (milk, meat, thin skinned vegetables) as much as possible.

haha SS! WTF? I soooo agree.

Jonsi -

That title - "Nanotechnology in Food? WTF!" Is actually the name of the article, copied and pasted in its entirety from a blog that appeared yesterday.

I've posted other articles in the past about food in nanotech. Yes, it is not new...I am just trying to keep up the awareness about nanotechnology so that it might really sink in.

I read another article today about how unaware the general public remains, even today, after all these years. This year marks the FIFTIETH anniversary of nanotechnology, and it remains an almost unheard of word!

Nano? No, no, no! A leading expert on organic farming warns against 'grey goo' technology

Healthy option: Organic and home-grown foods are more and more popular in Britain

Listening to Lord Krebs speak of 'low-calorie chocolate and beer that would never go flat' last week, one could be forgiven for feeling a sense of déjà vu.
These were just some of the wonders that the former head of the Food Standards Agency informed us one could look forward to with the 'explosive growth' of the use of nanotechnology - dubbed 'grey goo' when it was first condemned by Prince Charles - in our food industry.
Not that the average consumer will be aware of the presence of these nanoparticles. Delivering the House of Lords' Select Committee on Science and Technology's report on nanotechnology, Lord Krebs said he and other peers see no requirement for products containing these microscopic compounds to be labelled.
Nanotechnology involves whittling common materials down to the size of microscopic particles, allowing them to acquire unusual properties. Nanofood is food in which nanotechnology is used during its cultivation, production, processing or packaging. The techniques can be employed to reduce fat, salt or sugar levels, enrich food with supplements or sometimes extend a product's shelf-life.
We have stood on the brink of this 'brave new world' of food technology before, when turkey twizzlers seemed the last word in sophistication and the future was full of the endless, still unfulfilled promises of the GM industry.
And it is a vision that has been rejected - vociferously - before, not least by leading scientists who advised the Government that the release of nanoparticles should be, 'avoided as far as possible'.
As consumers we have already made our feelings known. Thanks in part to this paper's campaigning, GM has been kept out of British food. As a nation, our whole approach to food has moved steadily away from the laboratory to the allotment.
There is growing support for local and seasonal food; food with no, or fewer, pesticides and additives; a desire to know who produced our food, how it was grown or reared and what, if anything, artificial it contains through clear labelling.
Yet still Lord Krebs believes that nanotech has a vital role to play in making our food 'healthier and tastier' and that the food industry's job is to make sure the public accepts a 'technology that is coming down the tracks'.
The truth is that there is little scientific understanding about how these substances affect living organisms, and initial studies show negative effects. Which is precisely why the select committee's report must be used as a chance to review what we do, and what we do not, know about it.
That alone should be enough to convince most people that there is no place for nanoparticles in health and beauty products or food.
Giving evidence to the Lords committee, Vyvyan Howard, Professor of Bio-imaging at the University of Ulster, said that when materials are converted into artificially-small, mobile nanoparticles, they become more mobile within the body. Nanoparticles can get through cell walls in the same way viruses do.
Most worryingly, research has demonstrated that if you expose animals or humans to nanoparticles, the particles can travel through the body, crossing things such as the blood-brain barrier which has evolved to keep molecules that we do not want out of our brains. In this way, Professor Howard says, nanoparticles can act as a Trojan horse, allowing potentially damaging chemicals into vulnerable areas of our bodies.
It is not too alarmist to suggest that the consequences could be fatal. There is a series of diseases called 'protein misfolding diseases', mostly occurring in the central nervous system, including Alzheimer's, Parkinson's and spongiform encephalopathy.
If we are exposed to large doses of nanomaterials, and they are able to get into areas like the brain, Prof Howard believes they might be able to increase the rate of protein misfolding diseases.
There is now, he says, 'firm evidence that some engineered nanoparticles entering intravenously or via lungs can reach the brains of small animals'. That alone should be enough to convince us that there is no place for nanoparticles in health and beauty products or food.
Indeed, last year we learned that nanoparticles added to sun creams are being investigated for just such links. Of the £5.5billion invested in nanotechnology globally each year, much goes into the development of cosmetics and health products.
In spite of this danger, we are being asked to accept their use in our foods. It should be quite clear, as Prof Howard stated, that 'when something is brand new. . . like some of the chemicals that we have created that bio-accumulate and persist and that have hormone-disrupting capabilities - you have to take a precautionary stance'.
The Government's failure to follow scientific advice and regulate nanotech products is inexcusably negligent.
While the UK Government turns a blind eye to the risks, the European Commission is reviewing EU laws that control the use of nanoparticles to ensure regulations are strong enough to cope with their unusual properties.
But although the risks are known, and have been widely acknowledged by the most eminent scientific bodies, the Washington-based Project on Emerging Nanotechnologies has found that there are currently 84 foods or food-related products that use nanotechnology.
The food industry says none is manufactured in the UK, but with no labelling required, we simply cannot know. We may already be eating them - as the Lords committee admits, 'we are not clear what is out there in use at the moment'.
Five years ago, when top scientists advised in the strongest possible terms to avoid the use of nanoparticles, the Government acknowledged the risk but took no action.
Two years ago, the Soil Association banned the use of man-made nanomaterials from all our certified organic health and beauty products and textiles, as well as organic food. We are the first organisation in the world to take this action to safeguard public health.
I am well aware that the usual reaction to pleas for caution, for putting public safety first, is that public interest groups are anti-technology Luddites. But it isn't progress that we are against, nor science. The very basis for our opposition is science.
It is the continued drive towards nanotechnology that is outdated. Scientists working for big food companies started developing their nanotech ideas many years ago. Then it was still possible to believe that the future of food would be high-tech, that fast food would soon simply involve swallowing a little pink pill.
Nanotech food was part of a nightmarish vision for the future of global farming and food. Some thought that GM and nanotechnology were the keys to overcoming the multiple problems of falling yields from artificial fertiliser and pesticide-laden crops, continuing hunger and starvation, obesity and an increasing scarcity of the raw materials, such as oil, on which nonorganic food depends.
Food would be brewed in vast vats using GM ingredients, with added nanotech nutrients and vitamins. Scientists believed that the world could continue dramatic increases in dairy and meat consumption, even if the milk and steaks of the future actually came from laboratories, not cows.
Indeed, this vision relies on the greatest possible disconnection between farming and the public. That is why GM companies like Monsanto consistently oppose labelling of GM food, and why the Lords' report says that while consumers can expect to have access to information about the food they eat, 'blanket labelling of nanomaterials on packages is not, in our view, the right approach to providing information about the application of nanotechnologies'.
Thankfully, over the 20 years in which nanotech food has been on the drawing board, our food culture has started to change. No one wants a pharmaceutical approach to meals; that has been replaced by a desire for Fairtrade coffee, cereal and toast for breakfast. Most people value food that we grow or buy fresh, prepare ourselves and take time to eat with our friends of family. Nanotechnology is no longer a bold step forward, it is entirely retrograde.
The Soil Association is proud of its record for speaking up for the public good. We banned feeding cows' brains to other cows because it felt wrong to us, even though there was no scientific evidence to back our concern at the time. Many years later Mad Cow Disease was identified. We banned GM because of clear scientific uncertainties and risks and because it conflicts with organic values. All the recent evidence shows that there is a much greater health risk with GM foods than some scientist originally claimed.
We already know that this is the case with nanotechnology. In this the public's gut instincts are right and should be heeded.
