The tomato is the edible fruit of Solanum lycopersicum, commonly known as a tomato plant, which belongs to the nightshade family, Solanaceae. The species originated in Central and South America. The Nahuatl word tomatl gave rise to the Spanish word "tomate", from which the English word tomato originates. Wikipedia
Tomatoes are known for their high levels of lycopene, a potent antioxidant, but lycopene levels jump through the roof when tomatoes are cooked. Cornell University conducted a study in which the ability to absorb lycopene cooked at varying temperatures was measured; tomatoes were heated for 2 minutes, 15 minutes, and 30 minutes. Levels of these disease-fighting warriors went up with each incremental increase in heating.
