FRUIT VS VEGETABLE
Botanically, a tomato is a fruit, a berry, consisting of the ovary, together with its seeds, of a flowering plant. However, the tomato has a much lower sugar content than other edible fruits, and is therefore not as sweet. Typically served as part of a salad or main course of a meal, rather than at dessert, it is, in the US, considered a "culinary vegetable". One exception is that tomatoes are treated as a fruit in home canning practices: they are acidic enough to process in a water bath rather than a pressure cooker as vegetables require. Tomatoes are not the only food source with this ambiguity: bell peppers, cucumbers, green beans, eggplants, avocados, and squashes of all kinds (such as zucchini and pumpkins) are all botanically fruits, yet cooked as vegetables. This has led to legal dispute in the United States. In 1887, US tariff laws that imposed a duty on vegetables, but not on fruits, caused the tomato's status to become a matter of legal importance. The US Supreme Court settled this controversy on 10 May 1893, by declaring that the tomato is a vegetable, based on the popular definition that classifies vegetables by use, that they are generally served with dinner and not dessert (Nix v. Hedden (149 U.S. 304)). The holding of this case applies only to the interpretation of the Tariff Act of 3 March 1883, and the court did not purport to reclassify the tomato for botanical or other purposes.
The tomato is native to western South America.[2] Wild versions were small, like cherry tomatoes, and most likely yellow rather than red.[2] A member of the deadly nightshade family, tomatoes were erroneously thought to be poisonous by Europeans who were suspicious of their bright, shiny fruit.[3] This was exacerbated by the interaction of the tomato's acidic juice with pewter plates.[21] The leaves and immature fruit in fact contain trace amounts of solanine, which in larger quantity would be toxic, although the ripe fruit does not.[22]
Mesoamerica
Aztecs and other peoples in Mesoamerica used the fruit in their cooking. The exact date of domestication is unknown: by 500 BC, it was already being cultivated in southern Mexico and probably other areas.[23]:13 The Pueblo people are thought to have believed that those who witnessed the ingestion of tomato seeds were blessed with powers of divination.[24] The large, lumpy variety of tomato, a mutation from a smoother, smaller fruit, originated in Mesoamerica, and may be the direct ancestor of some modern cultivated tomatoes.[23]:15Spanish distribution
Spanish conquistador Hernán Cortés may have been the first to transfer the small yellow tomato to Europe after he captured the Aztec city of Tenochtitlan, now Mexico City, in 1521, although Christopher Columbus may have taken them back as early as 1493. The earliest discussion of the tomato in European literature appeared in a herbal written in 1544 by Pietro Andrea Mattioli, an Italian physician and botanist, who suggested that a new type of eggplant had been brought to Italy that was blood red or golden color when mature and could be divided into segments and eaten like an eggplant—that is, cooked and seasoned with salt, black pepper, and oil. It was not until ten years later that tomatoes were named in print by Mattioli as pomi d’oro, or "golden apples".[23]:13After the Spanish colonization of the Americas, the Spanish distributed the tomato throughout their colonies in the Caribbean. They also took it to the Philippines, from where it spread to southeast Asia and then the entire Asian continent. The Spanish also brought the tomato to Europe. It grew easily in Mediterranean climates, and cultivation began in the 1540s. It was probably eaten shortly after it was introduced, and was certainly being used as food by the early 17th century in Spain.
TABACO
HISTORIA
In their first voyage to the New World, Christopher Columbus and his expedition were introduced to a plant whose smoke was called tobacco by the natives of Hispaniola. In 1560, Jean Nicot de Villemain, then French ambassador to Portugal, brought tobacco seeds and leaves as a "wonder drug" to the French court. In 1586 the botanist Jaques Dalechamps gave the plant the name of Herba nicotiana, which was also adopted by Linné. It was considered a decorative plant at first, then a panacea, before it became a common snuff and tobacco plant. Tobacco arrived in Africa at the beginning of the 17th century. The leaf extract was a popular pest control method up to the beginning of the 20th century. In 1851, the Belgian chemist Jean Stas documented the use of tobacco extract as a murder poison. The Belgian count Hippolyte Visart de Bocarmé had poisoned his brother-in-law with tobacco leaf extract in order to acquire some urgently needed money. This was the first exact proof of alkaloids in forensic medicine.[2]
ME DÁ GRACIAS ORQUE EL DR LUIS MEDINA,ERA MAESTRO DE MATEMÁTICAS Y DEMOSTRABA LOS PELIGROS DEL TABACO,INYECTANDOLE EXTRACTOS DE CIGARRILLOS A LAS LAGARTIJAS,SE MORÍAN
HOY EN DIA HAY TANTOS ANUNCIOS,QUE NOS DICEN NO FUMAR. EL ABUELO DE MI ESPOSA USO LA MASCADURA DE TABACO,NUNCA TUVO CARIES EN LOS DIENTES
CREO QUE DE LA FLOR SE EXTRAE UN PERFUME CARÍSIMO
