Introduction

Definition:
Genetically engineered (GE) food refers to any product containing or derived from GMOs. Most recently, biotech companies have inserted herbicide-resistance genes into wheat, fish genes into strawberries, human genes into fish and pharmaceuticals like birth control into corn. Genetically modified food refers to the origin of food from genetically modified organisms, produced by genetic engineer. History:

Scientists first discovered that DNA can transfer between organisms in 1946.The first genetically modified plant was produced in 1983, using an antibiotic-resistant tobacco plant. In 1994, the transgenic Flavr Savr tomato was approved by the FDA for marketing in the US - the modification allowed the tomato to delay ripening afterScientist experimenting food picking.In the early 1990s, recombinant chymosin was approved for use in several countries, replacing rennet in cheese-making. In the US in 1995, the following transgenic crops received marketing approval: canola with modified oil composition (Calgene), Bacillus thuringiensis (Bt) corn/maize (Ciba-Geigy), cotton resistant to the herbicide bromoxynil (Calgene), Bt cotton (Monsanto), Bt potatoes (Monsanto), soybeans resistant to the herbicide glyphosate (Monsanto), virus-resistant squash (Monsanto-Asgrow), and additional delayed ripening tomatoes (DNAP, Zeneca/Peto, and Monsanto). In 2000, with the creation of golden rice, scientists genetically modified food to increase its nutrient value for the first time.

Advantages of Genetically Modified Food

Figure - Naturally grown food
Genetic modification can produce larger, hardier, tastier, and more nutritious foods. For example, Strawberries are sweeter, less acidic flavor; Soybeans have higher protein content, making them more nutritious for livestock and humans. Better production in lesser time, thereby providing food for more people. Have an increased resistance to spoilage with a better shelf life thus can be transported long distances better shelf life. They are potentially non-allergenic. Provides medicine and vitamin deficiency. For instance, scientists have discovered Golden rice containing to support deficiency of vitamin A causing blindness for half of the world population who live on rice.

Provide more resistance to diseases. Nowadays, plants can be genetically modified to be better able to survive abiotic extremes, such as frosty temperatures, heat waves, droughts, and poor soil chemistries. Provides an increased production of eggs, milk and meat. More economical to the farmer in terms of production of food. Provides improved health of the population and thereby reduces the economic burden. GE Saves the wild animals.

Disadvantages of Genetically Modified Food
Environmental activists, religious organizations, public interest groups, professional associations and other scientists and government officials have all raised concerns about GM foods most concerns about GM foods fall into three categories: environmental hazards, human health risks, and economic...
