Tomatoes are also on the list of toxic foods we love. Tomatoes are members of the nightshade family along with eggplants, potatoes, and belladonna. The plant parts of all contain solanine, an alkaloid that in high enough doses can cause gastrointestinal symptoms, hallucinations, paralysis and death.
Don’t eat the leaves and stems of tomato, potato or eggplants. Some people who are sensitive to solanine should avoid eating produce in the nightshade family. Green potatoes contain elevated levels of solanine, so avoid those.
