I’ve been working on some exciting things in the last few months. Watch this space for teasers.
There exists a myth that organic fruits and vegetables are healthier because they’re free from harmful pesticides. Bruce Ames, one of the key founders of the field of toxicology back in the 1970s, wrote a landmark paper in 1990 called Dietary pesticides (99.99% all natural), in which, he showcased some of the many naturally-occurring pesticides we ingest every day.
Because plants can’t run away, they attack predators with chemical weapons instead. All plants produce natural pesticides called secondary metabolites that deter predators to varying extents. The production of these secondary metabolites is upregulated during predatory attack.
Some of the natural pesticides that plants produce are toxic. Some are carcinogenic. Some studies have even suggested that if synthetic pesticides are not sprayed onto the surface of the crops, as might be the case in some types of organic farming, plants increase their production of natural pesticides to compensate for the resulting increase in herbivory attack.
Proponents of organic food fail to realise that everything we touch, eat and breathe contains miniscule traces of toxins. Our bodies evolved in a pretty dirty environment and can cope with low levels of toxins being ingested. Some studies even suggest that ingesting these tiny amounts of harmful substances might not only be harmless but beneficial to our health.
Contrary to popular belief, natural foods (wild varieties) are not safer, more nutritious nor more delicious than conventionally-farmed foods. Organic farming is an unsustainable luxury that offers no benefit to consumers’ health.
For more information on organic food, check out my latest book, Fighting Chemophobia, which is available by clicking the link below.
It’s been a while since I posted. I’ve been working on some things that will be revealed in the next few months.
The second batch of Fighting Chemophobia books are finished! After a long search, we have finally found two great companies for printing and distribution in China. Dianzan design and printing company has laid the book out with great care and precision and turned Fighting Chemophobia into an excellent-quality product in both hardback and paperback editions. The 80 gsm Dowling paper feels great, and there are even some full-page colour images scattered throughout the book. Shunfeng Express is handling cheap, quick shipping and is currently achieving 2-day deliveries within China. They predict 7-day delivery times internationally.
This second batch is higher quality than the first. I’m sure you’ll love what these people have produced.
Working with a publisher could have saved me the search for an editor, a printer, a distributor, a marketer and a translator. Self-publishing has been more rewarding in this regard: not only have I selected the people I’ve worked with to bring this book to completion but I’ve probably learned more this way about the process of writing, editing, printing, binding, marketing and distributing a book than if a publisher had handled the entire process on my behalf.

Chemophobia is an irrational fear of chemicals. It includes the fear of sugar in food, formaldehyde in shampoo and aluminium in vaccines. Fitness bloggers, quack doctors and even small cosmetic companies take advantage of these quirks to sell fake-natural products at elevated prices. Almost always, the same people who spread a fear of ‘chemicals’ also have ‘chemical-free’ products for sale.
Some companies sell “natural”, “organic” and “chemical-free” products to combat the supposed onslaught of chemical pollution in conventional consumer products. Most of these alternative products are no less synthetic, and no safer, than conventional versions despite commanding much higher prices.
Chemophobia is spreading despite our world becoming a cleaner, safer place. People are becoming healthier, and product safety regulations are becoming stricter. The supposed onslaught of chemicals that these special interest groups describe simply isn’t happening.
Perpetrators of chemophobia create unnecessary guilt, stress and anxiety as consumers worry about making the right choices for their family. Consumers are the victims in this battle as pro-natural and anti-natural businesses spread fear about each other’s products.
This book analyses psychological quirks, evolved millennia ago, that prime us to fall victim to chemophobic ways of thinking such anorexia, a fear of vaccines, a fear of fluoridation or a dangerous fear of synthetic medicines. It explores how consumers, teachers, doctors, lawmakers and journalists can fight chemophobia by tackling the social issues that underpin it.

Unlike purple and pink pigments, which were rare and expensive enough to be reserved for royalty and high-ranking clergy, yellow pigments were abundant throughout ancient history. Yellow ochre, a powdery mixture of iron oxides, has been used in cave paintings around the world for up to 80,000 years and was still being used by artists in the early nineteenth century. Saffron and turmeric were also used as yellow dyes throughout ancient history. Vincent van Gogh was using mineral yellow pigments such as cadmium yellow and chrome yellow in his mid-nineteenth century paintings. By the mid-nineteenth century, people looking for yellow pigments already had plenty of options. Despite there being no pressure from consumers for a new yellow dye, chemists trying to replicate the fame and fortune that mauveine brought to William Perkin in 1856 were experimenting eagerly in pursuit of that goal.
In 1861, Mêne was reacting aniline with cold nitrous acid to produce a diazonium salt solution. He then added more aniline to the resulting salt solution and shook the flask vigorously and noticed a yellow precipitate formed at the bottom of the flask, which would later become known as ‘aniline yellow’ – the first ‘azo dye’. 
The reaction mixture must be kept cool (at around 5 °C) because different temperatures cause different products to form. If the same reactants are mixed warm, then smelly liquid phenol and inert nitrogen gas are formed, both of which are colourless, and neither of which are useful as pigments!
At the time, the ‘aniline yellow’ powder he discovered was considered useless because it didn’t dissolve in water. However, it did dissolve very well in oil. The dye eventually gained some niche uses as a microscopy stain (like fuchsine) but was never utilised by the garment or pigment industry.
After staying relatively unused for over a hundred years, aniline yellow left an unfortunate legacy for itself by becoming the culprit molecule in the Spanish ‘Toxic Oil scandal’ of 1981. A batch of Spanish rapeseed oil had been denatured (deliberately adulterated) with 2% aniline yellow so the company could report it as “machine oil” and take advantage of certain tax breaks. One local refinery obtained the denatured rapeseed oil and attempted to remove the aniline yellow dye so they could sell it on as “pure olive oil” on the market for profit. They sold the oil around much of north-western Spain in unlabelled 5-litre plastic containers.
The first casualty was an eight-year-old boy who died upon arrival at a hospital in Madrid on May 1st, 1981. The rest of his family then presented with an unusual set of symptoms: headache, fever, itchy scalp, lethargy and interstitial lung disease. The hospital diagnosed the family with “atypical pneumonia” and treated them all with antibiotics but they showed little improvement. 
Across Spain, 20,000 patients presented with similar symptoms within one month of the incident. Thinking that an unexplained pneumonia outbreak was unfolding, a children’s hospital in Madrid conducted a randomised, double-blind controlled clinical trial on the effectiveness of the antibiotic erythromycin, which is particularly effective on infections of the respiratory system.  Unfortunately, they found no difference in recovery or mortality rates between the treated group and the control group and decided to keep looking for potential treatments.
Attempting all avenues, the researchers conducted lifestyle surveys on many patients, which included (among many other things) questions about cooking oil. Sadly, even though the source of the problem was staring them in the face, the results of the oil usage survey questions came back “inconclusive”. 
A baby ultimately solved the puzzle. Prognosis for young children was generally worse than for adults after they contracted the strange set of symptoms. Oddly, babies under six months were unaffected even if the entire rest of the family had presented with the pneumonia-like symptoms. Their infants were completely symptom-free. When one baby did get sick, however, this prompted deep and urgent questioning of the parents involved to find out what they did differently from others. One unusual aspect of the baby’s upbringing was that the baby’s grandmother had been ‘supplementing’ baby’s formula powder with cooking oil that was sold in an unlabelled 5-litre plastic container. 
Spanish government agencies acted quickly. The Ministry of Health and Consumer Affairs issued a recall of all oil sold in unlabelled plastic bottles within 40 days of the first casualty reporting with symptoms (the 8-year-old boy). Rates of patients presenting with symptoms of Toxic Oil Syndrome, as it would later be called, plummeted after the recall was announced on June 10th, 1981.
The aniline yellow had all been removed. The problem was a side-reaction, completely unknown to the scientists who were purifying the “machine oil”, that formed a new, harmful molecule that was large enough to escape their detection methods.
The molecule responsible for Toxic Oil Syndrome is called “OO PAP” in scientific literature. Visual inspection of OO PAP’s structure reveals that it’s quite simply an olive oil triglyceride molecule (triolein) with one of its three fatty acid tails replaced with a large aniline group.  When the rapeseed oil was adulterated with 2% aniline yellow to disguise it as “machine oil”, some of the aniline yellow molecules didn’t just blend in with the oil but reacted chemically with it to make OO PAP molecules. ITH, the company who sold the de-adulterated product as “pure olive oil”, was likely unaware of this chemical reaction, and therefore (we assume) also unaware of the poisonous OO PAP that had formed in the oil. While ITH successfully removed the aniline yellow, they failed to remove the OO PAP molecules, which escaped their filtration techniques.  Sadly, hundreds of people died and 20,000 more were made ill from OO PAP poisoning, and financial damage was estimated by El País newspaper to be 2 billion pesetas (around 16 million US dollars today).  Just like the scandal of the pink fuchsine socks, government and industry were forced to work together to respond quickly to a growing public crisis.
Every chemical – regardless of whether it’s found naturally or created synthetically – has the potential to be beneficial, harmful or harmless depending on the dosage and the way that it’s used. Aniline yellow, like all other chemicals, is incredibly useful when used correctly. It’s a fantastic microscopy stain but totally unsuitable for culinary use.
Today, people use aniline yellow to dye specimens for viewing under a light microscope. Aniline yellow’s dangers are stated clearly on its safety data sheets: handling it today requires training, permits, safety glasses, gloves and a lab coat to avoid all contact with skin and eyes. Now that chemistry has given us a better understanding of the aniline yellow, nobody dare use it to dye foodstuffs. 
The “deficit model” is a widely criticized theory that suggests that people who harbor attitudes of negativity or indifference towards science (in this case, chemistry) do so because they are uninformed about the topic (Chinese: 无知).
People’s misinformation might come from a lack of interest, a lack of exposure or an experience of poor science outreach in the past, where incorrect messages were delivered.
The “deficit model” stipulates that if people knew more about science, they’d naturally become more interested in it. Unfortunately, it doesn’t always seem to work, and the ‘model’ is subjected to routine criticism.
Criticisms of the “deficit model”
It is patronizing to the public, which alienates them further from science
It implies that there is only one coherent, correct narrative of ‘science’
It implies that people who don’t like science are misinformed about it
Learning science isn’t always fun
Being forced to learn something they’re not interested in could reinforce negative attitudes towards science
The public is too varied to attempt to give a “one size fits all” theory of science outreach
It ignores the fact that members of the public have individual preconceived ideas about science before they’re introduced to new science information
It relies too much on monologue/lecturing the public rather than engaging them in dialogues
Employ alternatives to the “deficit model”
Critics of the “deficit model” tend to advocate solutions that involve dialogue (rather than monologue) with the public. Dialogue works better when the particular public audience in question has pre-existing views about the scientific topic being discussed (called ‘affected/partisan’ public groups).
There are four main types of ‘public’ audiences. The table below summarizes each of these types and how to engage with them, and is adapted from Canek Phillips report from 2013.
The general public consists of people with diverse views that represent a cross-section of society. In a group, these views cancel out somewhat, hiding the deviation of views. The “deficit model” of monologue delivery is an effective way to engage such a group.
The pure public is a group of people who have no pre-existing ideas about the topic being discussed. The “deficit model” can engage these audiences as well.
The affected public can only be engaged if their pre-existing views are acknowledged and respected beforehand. Dialogue is an excellent way of doing this. Examples of dialogue-based approaches include science shops, public hearings, citizen judies, stakeholder consultations and focus groups.
The partisan public is sometimes led by charismatic leaders or lobby groups. Their views might have been shaped by influential figures (e.g. Mercola, Food Babe) and the pre-existing views (misconceptions) delivered in this way need to be debunked through respectful dialogue rather than monologue.
In short, before telling your audience something, find out whether they have any pre-existing ideas about that topic. If they don’t, then go ahead with a monologue delivery. If they do, then launch a two-way discussion with them, in which you listen and respect their views. Only then, will they respect your opinion as well. ♦
Humans are irrational beings. Smoking kills 480,000 people per year in the United States, while an average of 170 lives are lost to terrorism each year in the same country. Counterintuitively, terrorism receives more media attention than smoking despite having a relatively tiny risk because we’re predisposed to fear dangers imposed by other people more than dangers with which we choose to engage ourselves.
Another great example is aeroplane crashes. Airlines today have an excellent safety record and flying is usually the safest mode of transport (safer than making the same journey by road or rail). We overestimate the dangers of flying on an aeroplane because someone else is in control.
Conversely, because summer heat waves are a natural phenomenon, we’re prone to underestimating their danger: tens of thousands of people die from excessive summer heat each year in the United States alone.
Irrational: we worry about terrorist attacks more than summer heat waves
Our ‘perceived risk’ almost never matches the ‘actual risk’. In the bubble chart below, the area of the circles above the line represent how much we worry about each risk. The area of the circles below the line represents the actual size of the risk in terms of how many people are harmed each year. In many cases, there is a huge disparity between ‘perceived risk’ and ‘actual risk’.
The table below shows the factors that increase and decrease our perceptions of risk.
Let’s evaluate two examples. First, smoking:
Conclusion: people are predisposed to underestimate the risks of smoking (9:1)
Second example: azodicarbonamide (dough improver) added to bread
Conclusion: people are predisposed to overestimate the risks of adding azodicarbonamide to bread (1:9)
This strange psychological quirk is one of the roots of chemophobia that I discuss much further in my upcoming book, Fighting Chemophobia (coming out late 2017).
Try it yourselves: use the table to find out whether we’re likely to over-fear or under-fear aeroplane crashes, climate change and parabens in cosmetics. You’ll find that we overestimate the risks of chemical ingredients in our food and products not because they necessarily pose any danger, but because we have this strangely irrational way of assessing risk in the world around us. ♦
The wines your great-grandchildren might one day drink on Mars will soon be coming to a bottle near you. Ava Winery is a San Francisco-based startup creating wines molecule by molecule, without the need for grapes or fermentation. With complete control over the chemical profile of the product, Ava’s wines can be created safely, sustainably, and affordably, joining the food technology revolution in creating the foods of the future.
For Ava, foods in the future will be scanned and printed as easily as photographs today. These digital recreations will be more than mere projections; they will be true chemical copies of the originals, capturing the same nutritional profiles, flavors, and textures of their “natural” counterparts. Our canvas will be macronutrients like starches and proteins; our pixels will be flavor molecules. Future generations won’t distinguish “natural” from “synthetic” because both will simply be considered food.
Consider ethyl hexanoate, although scary-sounding it is the very chemical that gives pineapples their characteristic smell and also fruity wines a tropical note. From pineapples, or indeed other organisms, ethyl hexanoate can be extracted much more efficiently. By sourcing more efficient producers of each of hundreds of different components, wines can be recreated as their originals.
Future generations won’t distinguish “natural” from “synthetic” because both will simply be considered food.
In fact, by eliminating the variability of natural systems as well as potential environmental contamination, this digitized future of food can increase the safety, consistency, and nutritional profile of foods. Such food products can reduce overall land and resource use and be less susceptible to climate fluctuations. Indeed this future will see significant reductions in the costs of food production as the cost of the raw ingredients shifts to more efficient sources of each molecule.
So why wine?
We knew there would be a controversial love/hate relationship with our mission to build wine molecule by molecule. To the elite who value the high-end wine experience, our molecularly identical creation of the $10,000+ bottle of 1973 Chateau Montelena will be a mockery; but to the public, the $10,000 turned $20 bottle will be a sensation. To the purists who still believe organic is the only way to eat or drink healthily, our wine will get “some knickers in knots”; but to the nonconformists, our wine will be a contemporary luxury made by contemporary technology.
In short, wine is just the beginning. Soon, Ava hopes to build more food products molecule by molecule further blurring these lines between natural vs. synthetic while simultaneously making luxury items available for all. With our groundwork, the Star Trek future of food might be closer than we thought.
There’s an interesting psychological quirk that makes us yearn for a benevolent, caring Mother Nature that can cure our ailments without any side effects. Academics call it the “naturalness preference” or “biophilia”, and the Norwegians call it “friluftsliv” (literally: free-air-life).
Friluftsliv began in 18th century Scandanavia as part of a romantic “back-to-nature” movement for the upper classes. Urbanisation and industrialisation in the 19th century disconnected Norwegians from a natural landscape to which they’d been so interconnected for over five thousand years.
Norway’s sparse population, vast landscapes and midnight sun (in the summer months, at least) make it an excellent place for hunting and exploration. These ideal conditoins produced some of the greatest trekkers and hikers the world has ever seen. I’ll show you two heart-warming examples.
The first is Norway’s infamous explorer Fritjof Nansen, who (very nearly) reached the north pole in 1896 as part of a three-year expedition by ship, dog-sled and foot. When world war one broke out, Nansen put his trekking knowledge into practice by helping European civilians escape the perils of war and move to safer places. He facilitated several logistical operations in the early 20th century that saw the movements of millions of civilians across Europe. When famine broke out in Russia in 1921, he arranged the transportation of enough food to save 22 million people from starvation in Russia’s remotest regions. Deservedly, he was awarded the Nobel Peace Prize in 1922 for his efforts.
The second example is Norway’s Roald Amundsen, who was the first person to reach the south pole in 1911. Nansen lent his ship, Fram, to Amundsen for a north pole expedition in 1909. Before Amundsen set sail, however, he learned that two rival American explorers – each accompanied by groups of native Inuit men – had already reached the north pole and were disputing the title of “first discoverer” among themselves. When Amundsen finally did set sail, he took Nansen’s Fram vessel to Antarctica instead, where he and his team disembarked and trekked a successful round-trip to the south pole. While Amundsen admits he was inspired by Nansen’s successful polar expeditions, I’m sure that Norway’s vast landscapes, summer sun and long-standing tradition of “Allemansrätten” (the right to traverse other people’s private land) also contributed to Amundsen’s yearning for friluftsliv: the obsessive search for a truly untouched wilderness. (Amundsen 1927)
The world’s first tourist organisations were founded in Norway (1868), Sweden (1885) with the goal of helping Scandinavian elites in their search for true nature. When the Industrial Revolution brought many indoor, sedentary factory jobs to Scandinavia, workers craved the outdoors that their culture had been in harmony with for thousands of years. Elites in the late 19th century signed up to go on expeditions to escape encroaching urbanisation. Later, in 1892, a group of Swedish soldiers founded the non-profit organisation Friluftsfrämjandet, which provided outdoor recreational activities to the labouring classes with a particular emphasis on giving free skiing lessons to children. Thanks to Friluftsfrämjandet, and the working-time legislations that came into play in the early 20th century, the middle and lower classes were finally able to pursue their obsession with finding nature, or friluftsliv.
“…[W]e arrange activities to win great experiences, together. We hike, bike, walk, climb, paddle, ski and skate together. We train the best outdoor guides and instructors in Sweden. And we have fun together!” (Friluftsfrämjandet 2017)
Hans Gelter, Associate Professor at Luleå University of Technology, writes that even friluftsliv has become commodified in the age of consumerism. He claims that the high prices commanded for outdoor equipment and transportation to remote places act as a barrier between hikers and the nature they claim to be seeking. (Gelter 2000) In Deep Ecology: Living as if Nature Mattered (1985), Timothy Luke argues that outdoor pursuits are now more about testing fancy equipment than finding a deep connection with Mother Nature. Snowboarding is now more about testing the latest boards and wearing eye-catching outfits than it is about enjoying pristine mountain vistas. Golf is now as much about donning luxury clothing brands and using expensive golf clubs as it is about enjoying the outdoors. Even many shower gels and body washes now contain a drop of lemon essence or avocado oil – for which you pay an extra dollar – that adds nothing to the utility of the product. We do this because we crave nature in an industrialised world.
My book Fighting Chemophobia (coming at the end of 2017) is approaching 60,000 words in length. Copious reading and lively discussions with many colleagues and academics is helping to shape the stories in the book.

It’s been exactly three years since I uploaded the original banana poster.
In 2014, I soon followed up with podcasts, radio appearances, press interviews, a T-shirt Store and twelve more fruit ingredient labels. I’ve done six more customised fruit ingredients labels for private clients. The images have since appeared in textbooks, corporate promotional material, YouTube videos, T-shirts, mugs and aprons.
Momentum built in 2015. Parodies emerged online, and a copycat image appeared in one Chemistry textbook. I started writing about chemophobia and consulting with experts on how to address the issue. In short, it’s very, very complicated, and has deep evolutionary origins. I set a goal to understand chemophobia and provide a roadmap to tackle it effectively.
In 2016, my voluminous OneNote scribblings turned into a book. I have a first draft saved on OneDrive (thank you for keeping it safe, Microsoft) and I’ll be proofreading it on an long-haul intercontinental flight for you later today.
My next book, tentatively titled “Fighting Chemophobia”, will be published in late 2017.
I promise that my book “Fighting Chemophobia” will contain the following:
Stories you can share on a first date;
Maths – but just a little;
Chemistry – but not too much;
A deep exploration of chemophobia’s roots;
Tangible solutions to chemophobia;
More stories. Lots of true stories.
This “Fighting Chemophobia” book is for:
Educated people who are interested in a fascinating, growing social phenomenon;
People who want to settle the ‘natural’ vs ‘artificial’ debate;
People who love reading.

This post concludes the Periodic Table Smoothie experiment.
Recall that we’ve just finished adding one mole of nitrogen gas and created a bizarre boron polymer at the bottom of our vessel. The temperature was 350 °C and the pressure in our vessel was 891 kPa.
Today, we’re going to add 1.00 mole of oxygen gas, stand back and observe.
This is disappointing news.
Many of the substances in our vessel react (more accurately, explode) in the presence of oxygen but the ignition temperature for all of those explosions to take place is at least 500 °C. The temperature of our vessel is set at just 350 °C. At this temperature, nothing would actually happen.
There’s not enough activation energy to break bonds in the reactant particles in order to get the reaction started. We call this activation energy (EA) in chemistry. If we were to add a source of excessive heat (e.g. a matchstick), the vessel would explode.
Should we heat up the vessel to 500 °C and blow up the experiment right here?
If we did, the following reactions would happen:
Enough of these reactions – particularly the first three – are sufficiently exothermic to trigger a chain reaction – at least up to the reaction of oxygen with beryllium carbide. The vessel would bang, explode, and shatter. The helium would float away, dangerous lithium amide would fly out sideways, and polyborazine powder, whatever that is, would land on the floor.
Let’s not ignite our experiment – not yet.
Conclusion after adding 1.00 mole of oxygen gas
Amount in mol
Pressure: 891 kPa (higher than before due to the addition of nitrogen gas) Temperature: 350 °C (vessel is still being maintained at constant temperature)
Oxygen was relatively uneventful. Let’s add fluorine and see what happens.
Let’s add fluorine gas
The following three reactions would all occur as 1.00 mole of fluorine gas is added:
These two products are quite interesting:
HF, hydrogen fluoride, an aqueous solution of which was used by Breaking Bad’s Walter White to dissolve evidence (his victims)
NF3, nitrogen trifluoride, is used as an etching agent when making printed circuit boards (PCBs)
Let’s add neon gas
When 1.00 mole of neon gas is added, the total pressure inside the vessel increases but no reaction occurs. The concentrations of all the other gases present are unaffected.
That concludes our Periodic Table Smoothie experiment. The most interesting conclusion was the discovery of polyborazine, the bizarre solid that collected at the bottom of the vessel.
Also of interest was how easily we created ammonia, one of the simplest of biological compounds, just by mixing elements together. Could the compounds necessary for life be so easy to create that their existence is an inevitable consequence of the Big Bang? Is life inevitable? If the Big Bang were to happen all over again, would life occur? And would it look any different?
This book contains 50 lies taught in the VCE Chemistry course.
These lies include well-meaning simplifications of the truth, mistakes in the textbook, and, in a few extreme cases, blatant falsehoods.
This book isn’t a criticism of the VCE Chemistry course at all. In fact, I just want to highlight the sheer complexity of Chemistry and the need to make sweeping generalisations at every level so it can be comprehensible to our students. This is a legitimate practice called constructivism in pedagogical circles. (Look that up.)
Many of these ‘lies’ taught at VCE level will be debunked by your first-year chemistry lecturers at university.
Here’s a preview of some of the lies mentioned in the book. Check out all 50 by clicking the download link at the bottom of the page.
The content you’re learning now is probably not as true as it seems. Chemistry is a set of models that explain the macro level sometimes at the expense of detail. The more you study Chemistry, the more precise these models become, and they’ll gradually enlighten you with a newfound clarity about the inner workings of our universe. It’s profound.
Rules taught as ‘true’ usually work 90% of the time in this subject. Chemistry has rules, exceptions, exceptions to exceptions, and exceptions to those – you’ll need to peel pack these layers of rules and exceptions like an onion until you reach the core, where you’ll find Physics and Specialist Maths.
Enjoy this book. I hope it emboldens you to question everything you’re told, and encourages you to read beyond the courses you’re taught in school.
