Pesticides: Just How Bad Are They?

I think everyone would agree that it would not be a good idea to put pesticides in a saltshaker and add them to our food at the table. But there is little agreement when it comes to their use in agriculture. How much gets into our food? What are the effects on our health? On the environment? Is there a safer alternative?

Where should we look to find science-based answers to those questions? One place we should not look is books written by biased non-scientists to advance their personal agendas. A friend recently sent me a prime example of such a book: Myths of Safe Pesticides, by André Leu, an organic farmer whose opinions preceded his research and whose bias is revealed in the very title.

Phthalates and BPA: Of Mice and Men

Is your soup poisoning you? In a recent study  subjects who ate canned vegetable soup had markedly increased levels of BPA in their urine compared to those who ate freshly prepared soup. We are constantly bombarded with alarmist warnings about the dangerous chemicals in the products we use. Especially BPA (Bisphenol A) and phthalates. Beware plastic bottles! Beware rubber ducks! And now, beware canned soup!   BPA and phthalates are classified as endocrine disruptors. They have been discussed before on SBM here and here.  BPA has been accused of causing everything from obesity to prostate cancer. Phthalates have been accused of causing everything from breast cancer to reduced anogenital distance in baby boys (the significance of this is unknown: there is not even any standard for what the normal distance is).

In the book Slow Death by Rubber Duck

Using a variety of test methods, the authors determined individual “body burdens,” or the toxic chemical load we carry. The innocuous rubber duck, for example, offers a poison soup of phthalates that “permeate the environment and humans.” From other products and food we also have a collection of chemicals shorthanded as PFCs, PFOAs, PSOSs, and PCBs. None of them are good, and they are everywhere…

Is this science or irresponsible fear-mongering? What does the best evidence tell us? Should we be afraid of our canned soup and rubber ducks? (more…)
