Companies make a fortune selling detox products that are supposedly 'free' from chemicals.

But in reality chemicals are in everything we eat - unhealthy or not. Now a pair of scientists has created a video explaining why these claims are bogus and misleading.

It shows how bananas, for example, contain more chemicals than some sweets and explains that it is the dosage of chemical, rather than the chemical itself, which often causes problems.

Chemical cocktail: The video shows how bananas, for example, contain more chemicals than some sweets (listed above) and it is the dosage of chemical, rather than the chemical itself, which often causes problems

The ‘This is NOT natural’ video was produced by Toronto-based Mitchell Moffit and Gregory Brown from ASAPScience.

They say that many people will advise against eating food which contains chemicals that are hard to pronounce, yet a single blueberry contains methylbutyrate, oleic acid benzaldehyde among many more.

And in some cases, healthy foods contain more chemicals than processed sweets.

Harmless? The video explains that even non-harmful chemicals in food have the potential to become harmful at higher doses. ‘Foods are complex things and a little perspective can go a long way,’ the video concludes

In an example, a banana is shown containing more than 50 chemicals from riboflavin to histidine, yet a Love Heart has just 13, including paprika.

‘Everything around us is made up of chemicals from the water you drink to the air you breathe,’ said the pair.

‘Literally water is a chemical substance, which is why it's frustrating when companies consistently tout their foods as chemical-free.

‘Seriously, we can break down any food to look like a confusing a long list of foreign ingredients.’

The video continues that even non-harmful chemicals in food have the potential to become harmful at higher doses.

MUM WAS RIGHT! EATING SLOWLY HELPS YOU FEEL FULLER Your mother was right when she told you not to wolf down your food, research suggests. People who eat more slowly feel fuller and think they have eaten more than those who eat quickly, tests showed. Previous studies have found that slower eaters have lower BMIs – body mass index - than those who gobble down their grub. But the reason why eating slowly is linked to being thinner has, so far, been poorly understood. To investigate whether how quickly we eat influences how hungry we feel afterwards, researchers from the University of Bristol fed volunteers Sainsbury’s tomato soup through a tube into their mouths. This set-up prevented the researchers from judging visually how much soup had been eaten. The participants then had 400ml of soup pumped into their mouths at two rates. One was at a fast rate of 11.8ml for two seconds, followed by a four second pause. The other, the slow rate, was 5.4ml of soup for one second followed by a ten-second pause. The 40 volunteers, who were paid £15, were then asked how full they felt at the end of the meal and two hours after. Those who took the soup more slowly said they felt fuller than the fast eaters both immediately after the test and two hours later. Advertisement

For example, apple seeds have roughly the same toxicity levels as sodium thiopental used in lethal injections, with both becoming toxic at around 1000mg per kilogram.

But apples aren’t lethal because they contain so little of this chemical.

‘The truth is almost everything is poison at a high enough dose,’ continued the pair.

The scientists also use the examples of melons and sweetcorn.

Both are significantly larger and come in more varieties than when the foods were first grown, suggesting that neither are ‘natural’ in the traditional sense of the word.

Last year James Kennedy, a high school chemistry teacher from Melbourne, Australia, created a series of images to hammer a similar message home. His ingredient list posters for everyday foods such as eggs and bananas aimed to dispel the fear that has become associated with the word 'chemicals'

It doesn’t mean either of them are harmful or bad for people to eat, it just means the situation shouldn't be seen in ‘black and white,’

‘Foods are complex things and a little perspective can go a long way,’ the video concludes.

‘You simply can't leave a chemical-free life like some brands would like you to think and the word detox is strictly a marketing myth.’

ASAPScience advises researching foods to understand their relative health benefits rather than buying into the claims of companies blindly.

Last year James Kennedy, a high school chemistry teacher from Melbourne, Australia, created a series of images to hammer a similar message home.

His ingredient list posters for everyday foods such as eggs and bananas aimed to dispel the fear that has become associated with the word 'chemicals'.

He told MailOnline: 'As a high-school chemistry teacher, I made these posters for my students as a visual introduction to our Organic Chemistry course.

'I wanted 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.
