Genetically modified soybean oil can be eaten, no harm to the human body.
Generally in the supermarket to buy the transgenic corn oil and soybean oil is extracted, genetically modified soybean in the process of extracting the oil is genetically modified components such as proteins and DNA excluded, there is no genetically modified components in the oil, so it is safe.
For cooking oil, its main component is triglycerides, and the function of the gene transferred from GM soybeans is to allow plants to produce more EPSPS enzymes, which has nothing to do with the composition of vegetable fats and oils, so the subject matter of the composition of soybean oil has nothing to do with whether or not it is produced from GM plants.
Background
In the spring of 1996, many farmers in western Illinois, USA, planted a new variety of soybean that was transplanted with a gene from Petunia. This new soybean variety is resistant to the herbicide, glyphosate (toxic drop mix). Glyphosate kills regular soybean plants along with weeds.
Genetic engineering holds the promise of making food healthier for people, more predictable harvests, less use of synthetic pesticides and more efficient use of water. The fruits of genetic engineering are called "genetically modified" products, and the first to hit the market are small commodities, such as fresh tomatoes from supermarkets and an enzyme produced by a bacterium used in cheese production.
The enzyme previously had to be extracted from the stomachs of cattle. Genetically modified technology is finally moving out of labs and test plots and into everyday farming of crops like corn, soybeans and cotton.
