Not that it really matters; genetic engineering has little to do with prescription drugs.</i> Genetically altered food has hidden abilities to alter genes or functions of a person who eats it. I will try to explain it on an example: If the immune system do not recognize an agent - a "panic attack" is happened. We call it allergies. For instance, the immune system of the majority people recognizes dust and they have no allergy to dust. The immune system of minority people does not recognize dust and they have hyperreaction on dust. The simplest method to cure - insert dust information into memory bank of the immune system. It stops allergy in minutes and forever. Bolded it: in stage of dust allergy - dust but not the immune system manage the situation. No problems if only the body manages own environment. The same mechanism is for a food allergy. The immune system does not recognize certain ingredients or nutrients/chemicals of food. Transfer this mechanism to genetically altered food. Changed chromosomes create changed bio-metabolism and changed 3-D structure (and more) of molecules. They are become different from those the body (the immune system) recognizes well. It means that the body does not metabolize genetically altered food properly. It means that genetically altered compounds will take over normal functions and structures of the body and will change them as soon as it possible. Although, this mechanism is the same as typical allergy - but because alteration is going on a deeper level (genes) - consequences will come not in hours as with typical allergy but in years. And the worse is because it takes over the base of the body functions (genetically determined reactions) - it could unpredictably alter not only its eaters but also his/her children the person could have. If our mind does not understand things that drive our DNA, …, life - it does not mean they do not work and we will be free from the consequences of our "smart" decisions. P.S. If you would know a little bit the base of the theory - I would give you 100% checkable proof, in all other respects - you won't believe it and, therefore, won't test it (because it is too unusual approach).
