The title of the segment on the Dr. Oz Show was “The Secret Ingredient Companies are Hiding in Your Food.” What could that be? Some opiate to keep you coming back for more? Tetrahydrocannabinol to increase appetite? No. The segment was all about chemicals called phthalates. And companies are not hiding their presence any more than they are “hiding” the presence of numerous substances that are not added to our food supply on purpose but can be detected through sophisticated analytical methods. These include pesticide residues, corrosion inhibitors, PCBs, detergents, chloroform, cadmium, radium, mercury, aflatoxins, bacteria and a host of others. Some of these are man-made, some occur naturally, but all are potentially toxic if present in a high enough dose. Real more.
