Although tomatoes are often closely associated with Italian cuisine, they are actually originally native to the western side of South America, in the region occupied by Columbia, Ecuador, Peru, Chile, and the western half of Bolivia. The Galapagos Islands off the coast of Ecuador are also believed to be part of tomatoes' native area. The first type of tomato grown is thought to have more resembled the smaller-sized cherry tomato than the larger varieties.
Tomatoes are a rich source of several nutrients. They are well known for their high vitamin C content, but also contain significant amount of vitamin A, B vitamins including niacin
and riboflavin, magnesium, phosphorous and calcium.
Tomatoes are also a good source of chromium, folate and fiber.
In recent years a particular nutrient found in abundance in tomatoes, lycopene, has made many headlines for its disease fighting abilities. It is a powerful antioxidant and as such helps to protect the cells in our bodies from damage.
The fiber in tomatoes also helps lower cholesterol levels, helps prevent colon cancer and helps to keep blood sugars at a low level.
Tomatoes are a source of riboflavin which has been shown to be helpful for migraine sufferers by reducing the frequency of their headaches.
Unlike many foods, some aspects of the nutritional value of tomatoes actually improve with cooking.
Tomatoes are widely known for their outstanding antioxidant content.
Bone health is another area of growing interest in tomato research. Interestingly, the connection of tomato intake to bone health involves the rich supply of antioxidant in tomatoes. We don't always think about antioxidant protection as being important for bone health, but it is; and tomato lycopene (and other tomato antioxidants) may have a special role to play in this area.
While not well researched for all cancer types, tomatoes have repeatedly been show to provide us with anti-cancer benefits. The track record for tomatoes as a cancer-protective food should not be surprising, since there is a very large amount of research on tomato antioxidants and a more limited but still important amount of research on tomato anti-inflammatory nutrients.
