The History Of Food Modification L-Istorja Ta Modifika Ikel

Food is essential to human survival. Ikel huwa essenzjali għas-sopravivenza tal-bniedem. It provides the proteins, carbohydrates, fat, fiber, vitamins, and minerals needed to stay alive, grow, and stay healthy. Huwa jipprovdi l-proteini, karboidrati, xaħam, fibra, vitamini, u minerali meħtieġa li jibqgħu ħajjin, jikbru, u jibqgħu b'saħħithom. Food also serves other social and religious functions. Ikel jservi wkoll funzjonijiet oħra soċjali u reliġjużi. Seder meals, birthday dinners, awards banquets, wake buffets, and other food-related functions bring people together for a host of cultural purposes. Ikliet Seder, ikliet, ikliet birthday premjijiet, buffets riattivazzjoni, u oħrajn relatati mal-ikel funzjonijiet tressaq flimkien nies għal għadd ta 'għanijiet kulturali. In some fundamental ways, the role of food in human society has probably not changed very much in thousands of years. F'xi metodi fundamentali, ir-rwol ta 'ikel fis-soċjetà umana probabbilment ma nbidlitx ħafna fl-eluf ta' snin.

People seldom eat foods taken directly from nature—an apple picked from the tree or a raw piece of tuna pulled from the ocean. Nies rari jieklu ikel meħuda direttament minn natura 'tuffieħa qabad mill-siġra jew biċċa prima ta' tonn jinġibed mill-oċean. Instead, they peel, chop, steam, salt, cook, or otherwise modify foods before they eat them. Minflok, dawn qoxra, CHOP, fwar, melħ, kok, jew inkella jimmodifikaw l-ikel qabel ma tiekol minnhom. Processed foods have been part of the human diet from the beginning of human culture and still are, but to a much greater extent and in far more sophisticated ways. Ikel ipproċessat kienu parti mid-dieta tal-bniedem mill-bidu tal-kultura tal-bniedem u għadhom, iżda, fi grad wisq akbar u b'modi ferm aktar sofistikati. Food today is still treated by some very old processes, such as salting and drying, but it is also modified in ways resulting in products that barely resemble natural foods. Illum l-Ikel għadu ttrattat minn xi proċessi antika ħafna, bħal tmelliħ u tnixxif, iżda huwa wkoll modifikat modi li jirriżultaw fi prodotti li bilkemm jixbħu ikel naturali. Probably the most important single factor in the way food processing has changed over the past 2,000 years is chemical science. Probabbilment l-iktar fattur importanti fl-ipproċessar tal-ikel mod inbidlet matul l-aħħar 2,000 sena huwa xjenza kimika. Researchers have found ways of adding chemicals to foods to change their flavor, color, texture, or other properties. Riċerkaturi sabu modi ta 'żżid kimiċi għall-ikel għall-bidla togħma tagħhom, kulur, konsistenza, jew proprjetajiet oħra. They have developed methods for changing the physical and chemical Huma żviluppaw metodi biex ibiddlu t-fiżika u kimika

composition of foods to make them more nutritious or palatable. kompożizzjoni ta 'ikel li jagħmluhom aktar nutrittivi jew togħma. They have even invented new foods that do not exist in nature. Huma għandhom saħansitra vvinta ikel ġodda li ma jeżistux fin-natura.

Modern techniques of food modification have both benefits and risks. Tekniki moderni ta 'modifika ikel għandhom kemm benefiċċji u riskji. They make it possible, for example, for people to enjoy foods year round that were once available for only limited times of the year. Huma jagħmluha possibbli, per eżempju, għall-persuni li jgawdu l-ikel sena kollha li darba kienu disponibbli biss għal żminijiet limitati tas-sena. These techniques enable people in all parts of the world to have nutritious foods that extend their lives and reduce the risk of disease. Dawn it-tekniki jippermettu lin-nies fil-partijiet kollha tad-dinja li jkollhom ikel nutrittivi li jestendu ħajjithom u jitnaqqas ir-riskju ta 'mard. They present a range of new kinds of foods that earlier generations could hardly have imagined. Huma jippreżentaw firxa ta 'tipi ġodda ta' ikel li l-ġenerazzjonijiet preċedenti setgħu tantx immaġina.

But the modified foods produced by chemical research also have their downside. Iżda l-ikel modifikat prodotti minn riċerka kimika ukoll negattivi tagħhom. Some new products may contain additives that are harmful to human health. Xi prodotti ġodda jista 'jkun fihom addittivi li huma ta' ħsara għas-saħħa umana. The development of these foods may create hazards for the physical and biological environment. L-iżvilupp ta l-ikel jistgħu joħolqu perikli għall-ambjent fiżiku u bijoloġiku. And the development of new foods may be driven by concerns other than people's best interests—by the desire to make an economic profit, for example—that may not justify the effort. U l-iżvilupp ta 'ikel ġodda tista' titħaddem minn tħassib li mhumiex tan-nies aħjar interessi 'mill-xewqa li jagħmlu qligħ, per eżempju' li ma tista 'tiġġustifika l-isforz.

Questions about the value of modified foods arise frequently in today's world. Mistoqsijiet dwar il-valur ta 'ikel modifikat jinqalgħu spiss fid-dinja tal-lum. What constitutes a "good" food versus a "bad" food? Dak li jikkostitwixxi "tajba" ikel versus "ħażina" ikel? Are natural foods always and inherently better for people than processed foods? Huma ikel naturali dejjem u kwalitajiet intrinsiċi superjuri għal nies minn ikel ipproċessat? When does the use of chemical substances or chemical technologies improve the value of food, and when are they likely to reduce its nutritional value or create other kinds of problems for the consumer? Meta ma l-użu ta 'sustanzi kimiċi jew teknoloġiji kimiċi itejbu l-valur ta' ikel, u meta dawn huma probabbli li jnaqqsu l-valur nutrittiv tiegħu jew joħolqu tipi oħra ta 'problemi għall-konsumatur? Consumers often do not know the answers to these questions. Konsumaturi spiss ma jafux it-tweġibiet għal dawn il-mistoqsijiet.
