The tomato is the world's most popular fruit. And yes,just like the eggplant and the pumpkin,botanically speaking it is a fruit,not a vegetable. More than 60 million tons of tomatoes are produced per year,16 million tons more than the second most popular fruit,the banana. Apples are the third most popular (36 million tons) ,then oranges (34 million tons) and watermelons (22 million tons) .
Tomatoes were first cultivated in 700 AD by Aztecs and Incas. Explorers returning from Mexico introduced the tomato into Europe,where it was first mentioned in 1556. The French called it "the apple of love",the Germans "the apple of paradise".
Tomatoes are rich in vitamins A and C and fibre,and are cholesterol (胆固醇) free. An average size tomato (148 gram,or 5 oz = ounce) boasts only 35 calories. Furthermore,new medical research suggests that the consumption of lycopene―the stuff that makes tomatoes red―may prevent cancer. As with essential amino acids (氨基酸) ,they are not produced by the human body. Lycopene is the most powerful part in the carotenoid (类胡萝卜素) family and,with vitamins C and E,protect us from the free radicals that degrade many parts of the body.
The scientific term for the common tomato is lycopersicon lycopersicum,which mean "wolf peach". It is a cousin of the eggplant,red pepper,ground cherry,and potato,also known as the nightshade (颠茄) or solanaccae. There are more than 10 ,000 varieties of tomatoes.
