Natural pesticides in a cabbage


natural pesticides in cabbage

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.

It’s been a while since I posted. I’ve been working on some things that will be revealed in the next few months.

  1. Excellent article!

    We have not forgotten our discussion, but it is vacation season here so getting everyone rounded up has been difficult,

  2. This is kind of worrying. Your chemistry blog is reputable but with so much misinformation or blind journalism what can we really believe?

  3. I am willing to believe that pesticides are not that harmful to the amazing human body but what about their effect on the ecosystems that surround farms? Wouldn’t be better to research how to support a cabbage to manufacture its own secondary metabolites that only cabbage moth worms eat rather than spraying pesticides that can kill pollinators and other beneficial insects. When we spray pesticides they end up in places that they don’t belong. That’s why we should steer research and funding into helping plants defend themselves.

  4. Hi,
    Being a science teacher myself, involved as much as I can in promoting critical thinking, I must confess that I was a bit disappointed when I realized I couldn’t find any piece of evidence that allyl cyanide is carcinogenic as stated above…
    As you are well aware, our detractors will use any vulnerability to disqualify our arguments…
    I simply hope being wrong…
    Congratulations for this beautiful site!
