What are the advantages and disadvantages of genetically modified food?

First, the benefits of genetically modified food:

(1) Improve the nutritional value of agricultural products and produce food more quickly and efficiently.

(2) Using transgenic method to change the genetic information of organisms and assemble new genes, so that the future crops have the characteristics of high nutrition, storage resistance, pest resistance and herbicide resistance.

Second, the shortcomings of genetically modified food:

(1) Exogenous genes introduced by transgenic organisms can often express protein, which may cause changes in the metabolism and nutritional composition of organisms.

(2) Genetically modified crops themselves may become weeds.

(3) Related wild species of transgenic crops become weeds or super weeds.

(4) Transgenic crops may produce new virus diseases.

(5) The harm of transgenic crops to non-target organisms.

(6) Destroy biodiversity.

(7) Effects of genetically modified crops on ecosystems and ecological processes.

(8) Other unforeseeable risks.

Extended data

As of 20 13, all countries engaged in the research and development of genetically modified animals and plants have formulated corresponding policies and regulations to ensure the safety of genetically modified foods. For example, the United States has established a perfect management organization and strict safety standards for food safety and environmental testing, and strictly managed and effectively controlled the research, development, testing and production of genetically modified animals and plants. Before each genetically modified organism is released into environmental test and transferred to commercial production, it is necessary to evaluate and review its own biology and production process for safety and risk, and then pass its relevant standards for approval.

In order to unify the standards for evaluating the safety of genetically modified foods, the International Food Law Committee under FAO and WHO also decided to formulate international safety standards for genetically modified foods.

In China, the former State Science and Technology Commission first formulated the Measures for the Safety Management of Genetic Engineering, and then the Ministry of Agriculture formulated the Measures for the Implementation of the Safety Management of Agricultural Genetic Engineering on this basis, and at the same time established the Agricultural Bioengineering Safety Committee, which was responsible for the safety examination and approval of the main body of agricultural bio-genetic engineering in China.
