Surprising Benefits of the Humble Eggplant

9. Not-So-Deadly Nightshade

Eggplants contain solanine because they belong to the Solanaceae, or nightshade, family. A belief that eggplants caused insanity was widespread during the European Renaissance period. The fruits were called "mad apples" or "mala insana." The poison belladonna is part of the nightshade family, but so are tomatoes and potatoes. Miniscule amounts of solanine in eggplants are usually harmless, though concentrations may be higher in unripe fruits. Consult your doctor if you experience discomfort or suspect solanine sensitivity.
