What are G.M.O.'s
A genetically modified organism (GMO) or genetically engineered organism (GEO) is anorganism whose genetic material has been altered using genetic engineering techniques. These techniques, generally known asrecombinant DNA technology, use DNAmolecules from different sources, which are combined into one molecule to create a new set of genes. This DNA is then transferred into an organism, giving it modified or novel genes.Transgenic organisms, a subset of GMOs, are organisms that have inserted DNA from a different species. GMOs are the constituents of genetically modified foods. Um! Genetically Modified food lets take a closer look at this.
Genetically modified foods or biotech foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise[1] thanmutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective breeding; plant breeding, and animal breeding, and somaclonal variation. Since genetically modified food has been introduced into supermarkets, there has been much controversy as to whether it is actually safe.
Genetically Modified foods (GM foods) were first put on the market in 1996. Typically, genetically modified foods are transgenic plant products: soybean, corn, canola, rice, andcotton seed oil. Animal products have also been developed, although as of July 2010 none are currently on the market. In 2006 a pig was engineered to produce omega-3 fatty acidsthrough the expression of a roundworm gene. Researchers have also developed a genetically-modified breed of pigs that are able to absorb plant phosphorus more efficiently, and as a consequence the phosphorus content of their manure is reduced by as much as 60%.
Critics have objected to GM foods on several grounds, including safety issues, ecologicalconcerns, and economic concerns raised by the fact these organisms are subject tointellectual property law.Follow this link to see the method, modified crops, modified animals, health risks they will tell you about anyway. http://en.wikipedia.org/wiki/Genetically_modified_food

What are Genetically Modified (GM) Foods?Although "biotechnology" and "genetic modification" commonly are used interchangeably, GM is a special set of technologies that alter the geneticmakeup of organisms such as animals, plants, or bacteria. Biotechnology, a more general term, refers to using organisms or their components, such as enzymes, to make products that include wine, cheese, beer, and yogurt.
Combining genes from different organisms is known as recombinant DNA technology, and the resulting organism is said to be "genetically modified," "geneticall_y engineered," or "transgenic." GM products (current or those in development) include medicines and vaccines, foods and food ingredients, feeds, and fibers.
Locating genes for important traits—such as those conferring insect resistance or desired nutrients—is one of the most limiting steps in the process. However, genome sequencing and discovery programs for hundreds of organisms are generating detailed maps along with data-analyzing technologies to understand and use them.
In 2006, 252 million acres of transgenic crops were planted in 22 countries by 10.3 million farmers. The majority of these crops were herbicide- and insect-resistant soybeans, corn, cotton, canola, and alfalfa. Other crops grown commercially or field-tested are a sweet potato resistant to a virus that could decimate most of the African harvest, rice with increased iron and vitamins that may alleviate chronic malnutrition in Asian countries, and a variety of plants able to survive weather extremes.
On the horizon are bananas that produce human vaccines against infectious diseases such as hepatitis B; fish that mature more quickly; cows that are resistant to bovine spongiform encephalopathy (mad cow disease); fruit and nut trees that yield years earlier, and plants that produce new plastics with unique properties.
In 2006, countries that grew 97% of the global transgenic crops were the United States (53%), Argentina (17%), Brazil (11%), Canada (6%), India (4%), China (3%), Paraguay (2%) and South Africa (1%). Although growth is expected to plateau in industrialized nations, it is increasing in developing countries. The next decade will see exponential progress in GM product development as researchers gain increasing and unprecedentedaccess to genomic resources that are applicable to organisms beyond the scope of individual projects.
Technologies for genetically modifying foods offer dramatic promise for meeting some of the 21st Century's greatest challenges. Like all new technologies, they also pose some risks, both known and unknown. Controversies surrounding GM foods and crops commonly focus on human and environmental safety, labeling and consumer choice, intellectual property rights, ethics, food security, poverty reduction, and environmental conservation (see GM Products: Benefits and Controversies, below).
