Is the vat salad oil used in bigger and more upscale hotels genetically modified? Is there any harm to the human body by eating genetically modified food?

Genetically modified, not that thing, right? Potatoes and tomatoes are different in genes, so they are two things, but whether they are poisonous or not depends on a lot of experiments. Potatoes and tomatoes are not poisonous, but the first potato is poisonous. Don't say it must be poisonous or not. Through a lot of experiments. The experiment is being done now. The people who eat it are mice, and the descendants will know.
