(Almost) Nothing is Truly ‘Natural’ – Part 4

Corn isn’t ‘natural’

In 2014, I created a series of infographics to help convey this message. Corn, for example, used to be a spindly grass-like plant called teosinte, which Native Americans farmed and bred through artificial selection until it resembled the yellow corn of today.

In 9000 years, sweetcorn has become 1000 times larger, 3.5 times sweeter, much easier to peel and much easier to grow than its wild ancestor. In the 15th century, when European settlers placed new selection pressures on the crop to suit their exotic taste buds, the corn evolved even further to become larger and multi-coloured. Corn no longer resembles the original teosinte plant at all.

Watermelon isn’t ‘natural’

Watermelon began as a hard, bitter fruit the size of a walnut. It caused inflammation and had an unpalatable bitter taste. Thousands of years of artificial selection (unintentional genetic engineering) have resulted in a modern watermelon that bears no resemblance to its African ancestor. Modern (artificial) watermelons are sweeter, juicier, more colourful and easier to grow than their ancestral varieties.

Peaches aren’t natural, either

Peaches used to be hard, cherry-sized fruits with giant pips. Like corn and watermelon, peaches became larger, sweeter and juicier over thousands of years of inadvertent genetic engineering.

Bananas, wheat, pigs and all farmed animals and plants are not natural

Before agriculture, carrots were white and spindly. Wheat was tall and scrawny with little calorific value. Apples were tiny and sour with giant pips (like crab-apples today). Strawberries were tiny, bananas had stones in them, and pigs were viscous creatures with tiny backsides that made for a not-so-delicious ham. Cows didn’t produce much milk (just enough for their own calves) and chickens were skinny little creatures that laid eggs weekly rather than daily. Every species that’s ever been farmed by humans has been genetically modified over time as a result.

I keep making this point because our ancestors deserve credit for their hard work: they toiled in the fields for thousands of years to breed plants and animals that are suited to our modern tastes and lifestyles. For modern humans to call the results of our ancestors’ hard work ‘natural’ is an insult to the millions of ancient farmers who worked so hard to produce them.

Engineers (including genetic engineers) know that humans have toiled for millennia to change nature and suit it to our own needs – animals became tamer and meatier, and plants started producing more edible portions. I want to counteract the misconception that humans encountered nature in a ‘pristine’ state.

Great documentary snippet – Animal Pharm

[ancient humans] toiled in the fields for thousands of years to breed plants and animals that are suited to our modern tastes and lifestyles. For modern humans to call the results of their hard work ‘natural’ is an insult to our ancestors.

I show the above documentary my Year 10 Science students to demonstrate what is currently being produced using genetic engineering techniques. The video explains all the concepts mentioned in this article and is accessible for and educated audience of any age.

This post is part 4 in a weekly series on chemophobia. Next week, we’ll look at the psychology behind chemophobia.

All-Natural Banana Poster Series PDFs

Ingredients of an All-Natural Banana and other fruits set $99
New for 2016: Click to download free PDFs of all twelve All-Natural Posters

It’s been two years since I posted the All-Natural Banana. Motivation behind this poster was to dispel the myth that “natural = good” and “artificial = bad”. It’s been a very successful project. It’s spawned 11 more “Ingredients” posters, a successful clothing line, and has sold thousands of print copies worldwide via this website.

Online news portal io9 then published a news story about the All-Natural Banana, which was followed in quick succession by articles in Vox, Forbes, Business Insider, the New York Times and more.

The All-Natural Banana has now received over 700,000 views via this website and millions more views via social media.

From today onwards, you can download the original PDF artworks for free. They come with a Attribution-NonCommercial 4.0 International Creative Commons License, which means that you can share them, print them and modify them as much as you like for non-commercial purposes only.

I’ll be following this up with an article on the ‘Origins of Chemophobia’ next week. Subscribe to this website below or subscribe via my Apple News channel here.

Ingredients of All-Natural Cherries

Cherries are extremely sweet, and are unusual in that they contain more glucose (52%) than fructose (42%). Their bright red colour comes from the carotenes and capsanthin (the E160 colourings) that are present in high quantities throughout the fruit.

Cherry flavour comes from a huge collection of aroma compounds produced naturally by the cherry. To make all of these compounds in the lab, then mix them together in the correct proportions would be ridiculously time-consuming and expensive.

When making artificial cherry flavourings, only the first two compounds are usually added: (Z)-3-hexenol and 2-heptanone. Artificial cherry flavouring thus tastes absolutely nothing like real cherries: it lacks most of the ingredients that give real cherries their delicious flavour.

It’s quite a different story with oranges and lemons, though. Most of the flavour of oranges and lemons comes from (+)-limonene and (-)-limonene, which, by themselves, smell like orange and lemon, respectively.

Just 10 days after it was created, the Ingredients of an All-Natural Banana was already the third most Reddited post of all time on Reddit Chemistry.

They were downloaded 7,000 times last week from this website alone.

I didn’t intend to make any more of these images. Three was enough. But I decided to take this Ingredients theme a bit further after I saw how widely they’d been circulated on Tumblr, Twitter, Facebook, and various other social media sites—many of which are in foreign languages—and none of which, I use.

So welcome to the Store. There’ll be more products coming soon if people like what’s already up there. I welcome your feedback as always. James 🙂
