Known scientifically as Solanum lycopersicum, the tomato is the berry of a plant from the nightshade family, native to South America.
Despite technically being a fruit, the tomato is generally categorized as a vegetable.
Tomatoes are the major dietary source of the antioxidant lycopene, which has been linked to many health benefits, including reduced risk of heart disease and cancer.
They are also a great source of vitamin C, potassium, folate and vitamin K.
They are usually red when mature, but can come in a variety of colors, including yellow, orange, green and purple.
