The most widely used cooking oils for home use are soybean, canola, corn, sunflower, olive, and peanut. Other specialty oils are sold but aren’t widely used (e.g. grapeseed oil). Of the major cooking oils, olive, sunflower, and peanut oil come from crops where no GMO technology is used. In addition, any organic versions of soy or canola oil would not make use of any GM technology. However, through processing, one cannot tell the difference between GM and non-GM soy and canola cooking oils. They are chemically the same.
