Eggplant
Approach raw eggplant with caution. Raw eggplant contains solanine, the same toxin that makes raw potatoes problematic. “Young eggplants” in particular, or eggplants that were harvested early in their plant lives, contain the most of this toxin. You would have to eat a whole lot of raw eggplant to experience the unpleasant gastrointestinal effects of solanine poisoning, but you might want to go ahead and cook your eggplant anyway. Plus, some people may have allergic reactions to even small amounts of raw eggplant
Lima beans
Similarly to kidney beans, lima beans should always be cooked thoroughly. Lima beans contain cyanogenic glycosides, a compound created to protect plants by releasing deadly hydrogen cyanide when chewed raw, according to National Geographic.
