What are GMO foods?
GMO foods, or genetically modified organisms, refer to crops and organisms that have had their DNA altered using genetic engineering techniques. This modification is done to introduce new traits to the organism, such as increased resistance to pests, enhanced nutritional content, or improved shelf life. Common examples of GMO foods include corn, soybeans, and cotton, which have been engineered for traits like herbicide tolerance and pest resistance.
The process of creating GMO foods involves isolating and transferring genes from one organism to another, which can include genes from different species. This technology allows for more precise changes than traditional breeding methods, which can involve the mixing of large sets of genes. GMOs are subject to regulatory approvals in many countries, as their safety and environmental impact are assessed before they are released to the market.
