全天然香蕉也是来自化学

2013年底,我准备高中有机化学课的时候设计下面的全天然香蕉成份信息图形。

这几年,广告上写的三个关键词有全天然」、有机」、无化学成份」。我想通过这张信息图形告诉大家一切都是化学成份做出来的。大自然生产的化学成份比科学家在实验室里能合成的成份复杂多了。为了简洁我写了几十个组成香蕉的重要成份——还有几千个天然有机化学成份没写上。

全天然香蕉里面有一些成份是有毒性的。但是,因为香蕉里面的剂量极少,所以它们对我们的人体是无害的。大自然对剂量的掌握是非常精准的,自然界中,所有的化学成分都有完美的剂量。这个信息图形的意义是告诉大家:

  1. 世界上的一切都是来自化学
  2. 大自然生产的化学成份比合成成份还复杂多了
  3. 大自然生产的产品(如香蕉)并不纯净,因为有上万种成份在其中
  4. 讲毒理学不讲剂量是完全没有道理的

随心分享!

Fighting Chemophobia

Bananas contain unpronounceable ingredients, too. Ingredients of an All-Natural Banana by James Kennedy

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;
  • Chemistry people;
  • People who love reading.

To get your hands on a copy, subscribe to this blog for email updates. Just click ‘Follow’ somewhere on this page (its location depends on which device you’re using).

I promise that throughout 2017, you’ll receive teasers, snippets and discarded book fragments via this blog to get you excited.

ASAP Science Video: This is NOT NATURAL

AsapSCIENCE has made an awesome video called This is NOT NATURAL based on the work I’ve been doing on this site. Watch the video and read the comments thread for some insight into the discussion (and misinformation) that spreads online regarding ‘natural’ and ‘healthy’ products.

One of the most upvoted comments is actually a thinly-veiled advertisement for a book called “The Coconut Oil Secret: Why this tropical treasure is nature’s #1 healing superfood”. Click through to their product page and you’ll see why the natural/organic sector needs more regulation, and why consumers need to be better-informed.

Personal Care Product Ingredients: Are Natural, Chemical Free, and Organic Always Best?

Personal Care Product Ingredients: Are Natural, Chemical Free, and Organic Always Best? Reserach Review Thumbnails

Shaun Holt and I recently co-wrote a paper for Research Review on the ingredients found in personal care products (e.g. shampoos, lotions and cosmetics). We analyse the recent surge in demand for ‘natural’ products and the beliefs that have been driving it.

We’re not saying that natural products don’t work – in fact, quite the opposite. We’re saying that natural products, just like synthetic ones, can be harmful, beneficial or neutral depending on the dose and upon how they’re used. 

Article preview

The terms “natural”, “chemical free” and “organic” are used frequently to market personal care products. However, the exact meaning of these terms is still unclear for consumers, and the use of these terms on labels is still unregulated in some markets. The purpose of this review is to provide clarity on the meanings of these terms and the implications of their application in the marketing of personal care products. The importance of applying a science-based approach to the assessment and recommendation of personal care products is also emphasised. This review is intended as an educational resource for healthcare professionals (HCPs), including nurses, midwives, pharmacists, and pharmacy assistants.

The Ingredients in Food Phenomenon Continues…

Ingredients of an All-Natural Banana went viral back in January 2014 and attracted over 2 million views on various websites worldwide. The posters and t-shirts are now available in 7 different languages.

Since January 2014, I’ve sold almost $8,000 worth of merchandise online, including t-shirts, posters and coffee mugs, and next month, Banana T-shirts will be available in two physical stores in the US and the Netherlands. Other successful bloggers are picking up on the trend as well: here’s a great contribution to the ‘Ingredients’ phenomenon from Compound Chem:

My favourite contribution overall has to be this one (below). it’s simple and artistic and states a very strong message. It’s part of an educational series by Sense About Science, and you can download their groundbreaking report from their website here.

The reality boils down to six points:

  1. You can’t lead a chemical-free life.
  2. Natural isn’t always good for you and man-made chemicals are not inherently dangerous.
  3. Synthetic chemicals are not causing many cancers and other diseases.
  4. ‘Detox’ is a marketing myth.
  5. We need man-made chemicals.
  6. We are not just subjects in an unregulated, uncontrolled environment, there are checks in place.

In the meantime, I’ve been producing educational Chemistry and Physics booklets for VCEasy, which are being released for free to high-school students via the internet. (VCE is the name of our high-school syllabus in Victoria, Australia.)

The VCEasy Visual VCE booklets are designed to give students a concise, visual summary of all the essential knowledge for their VCE course—with nothing superfluous added, and nothing taken away. Just 100% VCE notes.

The design is highly visual, and each page corresponds to one Key Knowledge Point taken directly from the VCAA Study Design. More information (including free downloads) are available here.

“Ingredients” Lesson Plan

People have been asking me for the lesson plan that gave rise to the Banana Posters.

Here it is. Click the image to download it as a PDF. 🙂

It’s a great introduction to Organic Chemistry in the last year of high school or in the first year of university.

All-Natural Banana Has Gone Viral: 2M views

banana collage 2 million jameskennedymonash

This post is a shameless list of newspapers and famous blogs that published articles about the All-Natural Banana, which has now exceeded 2 million views on the internet.

It’s also spawned a successful clothing line and a poster print business. In other words, for what started as a simple teaching aid, “Ingredients” is getting pretty big. 🙂

Here’s the list:

I’m now sending multiple print shipments every day, most of them international.

It now exists in 7 languages. More on that soon.

It has over 120,000 ‘likes’ on Facebook (but I don’t use Facebook)

And it’s been shared widely across social media like Twitter. In other words, it’s gone viral.

Exciting changes to the T-Shirt Store will be announced tomorrow. 🙂 James

Banana/Blueberry/Egg Ingredients Poster PDFs

About these posters: As a Chemistry teacher, I want to erode the fear that many people have of “chemicals”, and demonstrate that nature evolves compounds, mechanisms and structures far more complicated and unpredictable than anything we can produce in the lab.

This visualisation has a short story behind it.

I usually care too much about food labels. If something has monosodium glutamate (E621) or high fructose corn syrup (HFCS) in it, I’m probably not going to buy it no matter how healthy or delicious the food looks as a whole. (Strangely, I’d be willing to eat it, though.)

Some people care about different ingredients such as “E-numbers”. I made this graphic to demonstrate how “natural” products (such as a banana) contain scary-looking ingredients as well. All the ingredients on this list are 100% natural in a non-GM banana. None of them are pesticides, fertilisers, insecticides or other contaminants.

There’s a tendency for advertisers to use the words “pure” and “simple” to describe “natural” products when they couldn’t be more wrong. With this diagram, I want to demonstrate that “natural” products are usually more complicated than anything we can create in the lab. For brevity’s sake, I omitted the thousands of minority ingredients found in a banana, including DNA 😉

Enjoy!
