Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism.enetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism.
When food-crops are genetically modified, (genetically modified food is a misnomer!) one or more genes are incorporated into the crop's genome using a vector containing several other genes, including as a minimum, viral promoters, transcription terminators, antibiotic resistance marker genes and reporter genes. Publications on GM food toxicity are scarce. 2  An article in Science magazine said it all: Health Risks of Genetically Modified Foods: Many Opinions but Few Data.1 In fact, no peer-reviewed publications of clinical studies on the human health effects of GM food exist. 3  Even animal studies are few and far between.
