Do you think genetically modified food can control human diseases prevention?Genetically modified food seeds through genetic engineering to change in the DNA, and then re-modified compound of these gene transfer to some other plant seeds, and achieve in nature do not automatically grow the plant species. For example, using deep-sea fish genes can help tomatoes, strawberries and other common plants to withstand the cold; to some bacterial genes that access to maize, soybean plants, we can better protect them from pest attack.

The late 80s of last century, scientists have begun to more than 10 years the results of molecular studies into the use of genetically modified food, in 1995 succeeded in producing soybeans resistant weeds, and sold on the market. After another seven years of hard work, and now they have been mass-produced using gene technology, pest-resistant, anti-virus, anti-genetically modified weed corn, soybeans, rapeseed, potatoes, squash and so on. At present, the world has more than 60 kinds of genetically modified crops, mainly in the United States, Canada, South Africa, Argentina and other countries. 

Genetically modified food is a new thing, most people it is poorly understood, combined with inadequate publicity so that people of genetically modified food safety doubts. International community, particularly in Western Europe, the strong emergence of resistance to genetically modified foods trend. EU genetically modified food production and marketing has drawn up regulations to require genetically modified genes may not exceed 1% of the total market for sale of genetically modified food must be labeled, also asked the relevant international agencies to genetically modified food and its right of innocent Environmental impact of scientific examination. 

In June 2001, the State Council issued the "Agricultural Genetically Modified Organism Safety Management Regulations"; in March 2002 the Ministry of Agriculture promulgated the "agricultural genetically modified organisms Identity management approach" to determine the first identity management, agricultural genetically modified organisms: soybean seeds, soybean , soybean meal, soybean oil, soybean meal, corn seeds, corn, corn oil, corn flour, oil.

Pairs of genetically modified foods harmless assessments are mainly the following aspects: whether the toxic, cause allergic reactions, nutritional or toxic properties of proteins injected genetic stability of the genetic changes caused by nutritional effects and other unnecessary functions. On human health, experts say, the main genetically modified foods should be examined whether the toxicity and impact on the environment. 

Experts believe that, due to genetically modified crops to better prevention and control diseases and pests, resist drought, improve yield, nutrient composition high, very broad prospects for development. By 2015, global population will increase to 9 billion, only to increase agricultural productivity to meet human needs for food, while modern biotechnology is undoubtedly an important means to increase agricultural productivity is one. People can also use genetic technology to produce fast-growing fish, and the vaccines required for the pharmaceutical industry, in order to meet the needs of human life. But experts also stressed that the development of genetically modified foods must be strict supervision, scientific testing, international legislation, in order to avoid its damage to human health and the environment.
