The vast majority of scientific research has found genetically engineered foods to be generally safe. An Italian scientist’s review of 10 years of research, published in 2013, concluded that the scientific research conducted so far has not detected “any significant hazard directly connected with the use of GM crops.” The Center for Science in the Public Interest, a well-known critic of food companies and artificial and unhealthy ingredients in foods, has not opposed genetically modified foods, on the basis that there’s no evidence they are harmful.
