Unexpected dangerous substances may be present in GE foods. This is because the procedure for assessing the safety of GE foods is not designed to detect them. Most of soy and corn products in the US and Canada are GE and labeling is not required there. Organic products are reliably GE-free.
Scientists are being harassed if they tell the truth about GMO hazards. Research on GMO hazards is being suppressed and negative research reports have been destroyed. Scientist who say GMO-foods are safe are not seldom lying out of fear of becoming unemployed and unable to get any new research job. Read the alarming stories.
This is a revealing video interview about the corruption of FDA and dishonest science that made it possible to launch GMOs in spite of warnings of FDAs own scientists. It also covers major hazards including concrete examples of severe damage from GMOs. We recommend Jeffrey M Smith's books: Seeds of Deception, GMO Trilogy, and Genetic Roulette.
American doctors warn: Avoid Genetically Modifed Food
The American Academy of Environmental Medicine (AAEM) has stated,
"Several animal studies indicate serious health risks associated with GM food," including infertility, immune problems, accelerated aging, insulin regulation, and changes in major organs and the gastrointestinal system.
They conclude, "The strength of association and consistency between GM foods and disease is confirmed in several animal studies."
