Transgenic foods are genetically modified foods that contain ingredients from organisms whose genes have been altered. While large companies claim GM foods are safe and can help address hunger issues, critics argue they pose unknown health and environmental risks and go against natural order. Studies show GM foods do not deliver on promises and could increase hunger by encouraging corporate control of small farms. Spain is unique in Europe for large-scale GM farming, but critics say consumers see no benefit given risks and profits have gone to American, not Spanish, farmers.
