When is the last time you had some eggplant? Chances are not recently, as it is considered a delicacy and an unorthodox vegetable by many people. However, the eggplant is actually a fruit, known in some places as an aubergine. Eggplant is a good source of fiber, vitamins B1, B6 and K, copper, manganese, niacin, potassium and folate. Eggplant also contains phytonutrients such as chlorogenic acid and nasunin.
