And I think it is important to note that these are problems when GM foods are 'in' us and I think we will find that there are parallel problems with these foods 'in' nature.

Several recent studies confirm fears that genetically modified (GM) foods damage human health. These studies were released as the World Trade Organization (WTO) moved toward upholding the ruling that the European Union has violated international trade rules by stopping importation of GM foods.

Research by the Russian Academy of Sciences released in December 2005 found that more than half of the offspring of rats fed GM soy died within the first three weeks of life, six times as many as those born to mothers fed on non-modified soy. Six times as many offspring fed GM soy were also severely underweight.
In November 2005, a private research institute in Australia, CSIRO Plant Industry, put a halt to further development of a GM pea cultivator when it was found to cause an immune response in laboratory mice.1
In the summer of 2005, an Italian research team led by a cellular biologist at the University of Urbino published confirmation that absorption of GM soy by mice causes development of misshapen liver cells, as well as other cellular anomalies.
In May of 2005 the review of a highly confidential and controversial Monsanto report on test results of corn modified with Monsanto MON863 was published in The Independent/UK.
Dr. Arpad Pusztai (see Censored 2001, Story #7), one of the few genuinely independent scientists specializing in plant genetics and animal feeding studies, was asked by the German authorities in the autumn of 2004 to examine Monsanto’s 1,139-page report on the feeding of MON863 to laboratory rats over a ninety-day period.

The study found “statistically significant” differences in kidney weights and certain blood parameters in the rats fed the GM corn as compared with the control groups. A number of scientists across Europe who saw the study (and heavily-censored summaries of it) expressed concerns about the health and safety implications if MON863 should ever enter the food chain. There was particular concern in France, where Professor Gilles-Eric Seralini of the University of Caen has been trying (without success) for almost eighteen months to obtain full disclosure of all documents relating to the MON863 study.

Dr. Pusztai was forced by the German authorities to sign a “declaration of secrecy” before he was allowed to see the Monsanto rat feeding study, on the grounds that the document is classified as “CBI” or “confidential business interest.” While Pusztai is still bound by the declaration of secrecy, Monsanto recently declared that it does not object to the widespread dissemination of the “Pusztai Report.”2

Monsanto GM soy and corn are widely consumed by Americans at a time when the United Nations’ Food and Agriculture Organization has concluded, “In several cases, GMOs have been put on the market when safety issues are not clear.”

As GMO research is not encouraged by U.S. or European governments, the vast majority of toxicological studies are conducted by those companies producing and promoting consumption of GMOs. With motive and authenticity of results suspect in corporate testing, independent scientific research into the effects of GM foods is attracting increasing attention.

Comment: In May 2006 the WTO upheld a ruling that European countries broke international trade rules by stopping importation of GM foods. The WTO verdict found that the EU has had an effective ban on biotech foods since 1998 and sided with the U.S., Canada, and Argentina in a decision that the moratorium was illegal under WTO rules.3

All GM foods are not created equal. When considering GM foods for human consumption, one has to look at what featured were added and modified to base possible toxicity or not. A GM modified rose scented rice may not have any adverse effect but plants growing cyanide would.

Use common sense not "no sense"....

Certainly there will be differences between different GM foods. But if I am getting non GM wheat the odds are my body is set up to deal with the chemicals it is made of. If it is something put together to resist Roundup pesticides and has genes from other species, who knows. Oddly enough very smart scientists are creating products as if it was relatively easy to track the consequences of these combinations. It is not. They should remember how it felt looking at their first organic chemistry books and being told this was the simple stuff.

I know little about GM foods, but have the distinct idea that only relatively simple molecules - like amino acid sizes or smaller - can pass thru he intestine walls into the blood stream. I.e. I thought that was what "digestion" was all about. Am I wrong in this belief? I.e. can the longer strings of DNA that make the GM foods different from those that have been developed over the centuries by "selective cross breading" pass in tact thru the intestine walls? I know that some of the species (or even kindom) "cross breading" limitation have been overcome by "genetic enginnering" but does this mean noval compounds, not ever before found in our intestines are now able to cross the walls and enter the blood? (or are only the same old small molecules able to do that, even if "pre-digestion" they were assembled into new compounds? - If that is the case, how could GM food be a new danger?)

But if I am getting non GM wheat the odds are my body is set up to deal with the chemicals it is made of.

Yes and no...even if a body has not seen the chemical, it will use the chemical based on the properties of that Chemical. Otherwise, new drugs would not work on human bodt...it would simply pass through....

Oil extractions made from a GM rapseed, cotton seed etc are exactly same as the non-GM variety. It is the whole plant, like leaves or fruits that produce the toxic chemicals in addition to basic sugar, protein etc....which are the same.
