Tomatoes are actually fruits and not vegetables. A fruit is the edible part of the plant that contains the seeds, while a vegetable is the edible stems, leaves, and roots of the plant.
History
Tomatoes first grew as wild cherry sized fruits in the South American Andes. They were grown by the Aztecs and the Incas as far back as 700 AD. But the tomato, as we know it today, originates from Mexico. Explorers coming back from Mexico introduced tomatoes to Europe in the mid 1500's. Tomato seeds were taken to the Mediterranean countries where they quickly became popular. There are now more than 7,000 varieties of tomatoes. The most widely available groups of tomatoes are cherry tomatoes, plum tomatoes and the larger, more common, slicing tomato. China is now the largest producer of tomatoes.
Nutritional and health information
Eating tomatoes at least twice a week is now believed to reduce the risk of prostate cancer and to be beneficial in fighting other forms of cancer. The key ingredient in tomatoes is Lycopene which is a carotenoid. In fact it is the most powerful of all the anti oxidants in the carotenoid family. Cooking tomatoes, most especially in oil, releases the Lycopene making it more available to the body. Tomato puree and tomato paste are more concentrated forms of tomato so they contain more lycopene then the equivalent weight of fresh tomatoes. Some brands of tomato sauce (tomato ketchup) contain as much as five times the lycopene contained in the equivalent weight of fresh tomatoes.
Tomatoes are also said to be good for the eyes. Lycopene is the key antioxidant that guards against ARMD (Age-Related Macular Degeneration), a condition that may cause blindness.
Tomatoes also contain calcium, potassium, Vitamins A and C. Recent studies are showing a link between eating concentrated tomatoes, as in tomato paste, and an increase in the bodies capacity to protect itself against sunburn.
Tomatoes that are ripened on the vine have far more vitamin C than those that are picked green. And as if that isn't enough, tomatoes contain very few calories, they are fat-free and they contain heaps of fibre.
Uses of Tomatoes
Although they are really a fruit we tend to use tomatoes in savoury dishes. Tomatoes are used in various processed forms such as tomato paste, tomato puree and of course tinned tomatoes in juice. They are the most popular salad ingredient after lettuce and they are used in pasta sauces and tomato sauce (tomato ketchup).
Important facts
Tomatoes should never been kept in the fridge. The flavour is far better when they are kept at room temperature. Consequently it is not advisable to buy tomatoes that have been stored in the shop in a chiller.
