GM foods are fairly new to the market, first commercialized and marketed in the early 1990s. The first commercial GM produce was the tomato, genetically engineered to be more resistant to rotting. Then, in 1996, soybeans genetically modified to be more resistant to herbicides were released for commercial sale. Currently, GM ingredients make up the majority of all processed foods in the US. However, there are no laws in the US requiring companies to label their foods as genetically modified.
