Are grape tomatoes organic or natural, or are they a genetically modified food?
Just prior to answering your question, I would like to address some of the terms you have used in your question. Natural has no useful application in technical terms and it is really just a term used by people in the marketing business. Something that is natural is generally perceived to have come from nature, and a plant that is genetically modified could still be described this way. Grape tomatos are just a variety of smaller tomatos, no GM involved. Whether they are organic depends on the classification of the farm they were grown on. Certified organic product usually has a label saying so on the packaging.
