Chii chatinoziva nezvegamu? Akanaka "namozolila" maziso edu mune zvekutengeswa, anoda vana vedu uye dzimwe nguva tinozvitsvaga kana pane musangano wakakomba. Asi chii chaizvoizvo ichi chirwere chekucheka, zvibatsiro zvayo uye zvinokuvadza kwatiri isu nevana vedu tinoramba tichibvunza mibvunzo. Asi izvi hazvirevi kuratidzika zvisina kufanira.
Kucheka gum munzvimbo dzevanhu zvinonyatsopesana nekutaura kwakanaka, asi dzimwe nguva zvinongodiwa. Kutaura zvazviri, kudzora gum kunogona kupa zvakawanda kupfuura mweya mutsva uye kunakidza kufara. Asi usati wataura chimwe chinhu pamusoro pekubatsira kwechigadzirwa ichi, chirevo chinotevera chinofanira kuitwa: cheku gum inogona kubatsira chete kana isina shuga uye kana kushandiswa kwayo kusingapfuuri nemaminitsi makumi matatu pazuva.
Nhoroondo ye chewing gum
Iyo inofungirwa zvepamutemo kuti chewing gum yakagadzirwa pakati pezana remakore rechi19. Muna 1869, William Example kubva kuOhio akagamuchira patent yezvigadzirwa zvake, iyo chekutu mashoma nenzira yeplasine. Iyi cheku gum yakanga ine unhu hwakasiyana-siyana hunofanana nehuni. Yakakurumbira yakadaro chewing gum yakafara zvishoma nezvishoma, kusvikira zvishoma gare gare haina kuve yakanaka uye yakasvibiswa nezvimwe zvinonakidza uye zvakajairika zvinowedzera. Makore makumi matanhatu chete gare gare gum gum yakawana kutaridzika kwemazuva ano. American Walter Dimar akakwanisa kuwana muyero wakakwana pakati pezvikamu zvayo: 20% rubber, 60% shuga kana nzvimbo inotsiva, 19% yehusi yehusi uye 1% flavorings. Chiratidzo chikuru chehutano chegamu, hongu, chakanga chiri uye chinoramba chichiwedzera.
Kutaura zvazviri, kudzora gum kwakauya kuvanhu kare kare. Kana kuti-panzvimbo-mumaNeolithic ekutanga. Vanochera matongo vakawana mapepa emeno muzvidimbu zveasin. VaGiriki vekare vaisarudza resin yemiti coniferous, kusiyana neMaya, uyo akashandisa sapodil wood resin.
Mazuva ano, mauto eUnited States akagadzira rudzi rutsva rwekucheka gum rine zvinhu zvinorwisa antibacterial zvinobvumira masoja kuti 'asvute' mazino avo apo pahondo. Kubatsira kwechirongwa ichi kwakajeka - zvingave zvinobatsira kune vakawanda vasiri vanhu vanoita basa rakabatikana. Imwe mhando yekugadzirwa kwevasayendisiti veAmerica ndiyo chewing gum ine zvinyorwa zve caffeine, izvo zvinokwanisa kuchengetedza masoja pamirairo kwenguva yakareba kuitira kuti varege kuziva kuneta kana kurara.
Utsanana hwehuwandu hwemuromo
Kudzingisa gum ndiyo yakanaka yekudzivirira kukanganisa caries. Kushandiswa kwezuva nezuva kwekofi newaini tsvuku, pamwe nekusvuta kunoshandura mararamiro eefelamendi mazhinji. Asi isu tose tinoziva kuti mazino kuchena chinhu chinonyanya kukosha chemuviri wavo. Ichokwadi kuti hapana cheku gum inogona "kurarama" chete nematope pameno, asi ichi ndicho chimwe chimwe chikonzero chakanaka chekurwa navo.
chewing gum inotsigira muromo unonyorovesa, inokurudzira salivation, nokudaro ichibatsira kubhadhara kuipa kweAidhi pazinoo mazino mushure mekudya. Pamwechete, mazino anocheneswa nokugadzirisa "kusungira" zvigadziro zvezvokudya kusvika kune bhanhire rakasununguka. Vanongonamatira pazviri, uye chaizvoizvo matsimba akadaro chimwe chezvikonzero zvinokonzera caries, izvo zvinopedzisa kuparadza nzvimbo yekudzivirira yezino. Hatifaniri kukanganwa pamusoro pemhepo inofema. Chewing gum inozorodza - izvi ndezvechokwadi. Ichokwadi, izvi zvinogumira munguva.
Tinofanira kungwarira pakusarudza chewing gum kuvana vedu, kuitira kuti tisavakuvadza. Mazino evana anonyanya kunetseka nehuga (dzimwe nguva inogona kuonekwa ichitonhora uye kunyange kuora kwemeno emukaka, izvo zvinogona kutungamirira kumatambudziko akakura nemazino anogara nokusingaperi). Zvinenge zvichibatsira kana cheku gum yatinotenga kune vana haina shuga uye inowedzerwa ne fluoride uye xylitol. Iko xylitol iyo inobudirira inodzivirira kuumbwa kweplate uye caries. kushandiswa kwaro kwemeno kwakaoma kurondedzera.
Zvakakosha kuyeuka kuti hakuna cheku gum inogona kutora nzvimbo yekusvina mazino uye mazino emasuo - maitiro ayo nekukuvadza zvinogona kukonzera kukakavara, asi chimwe chinhu chisingatenderwi - unoda kusveta mazino ako chero. Karoti nemaapuro, zvakare, hazvina basa munyaya iyi.
Kurara kwekuzvidzivirira mukati memuromo
Kunhuwirira kunofadza, hongu, haisi chinhu chinonakidza chinogona kuitika kwatiri. Asi, neruremekedzo, mint chewing gum inobudirira kurwisana nechinetso ichi, kukanganisa uye kupedza kunhuhwira kubva mumuromo. Zvingave zvinobatsira, zvisinei, kana chewing gum iri ne lactic acid bacteria, kutarisira kuenzana kwemabhakitiriya aripo mumuromo wemuromo. Masangano akadaro akaiswapo uye anowanikwa mune dzimwe nyika. Mukuwedzera, imwe cheku gum inoshandiswa ne aluminium lactate, iyo inonyanya kuderedza kubuda ropa kubva mumasamu uye inoderedza kupisa. Iyi inokosha yekurapa chewing gum - iyo inobatsira kune vanhu vanotambura nedzimwe nguva dzechirwere, kuongororwa uye kusimbiswa neyanyanzvi.
Kuvharwa kweAidhi kupinda mueophagus
Ichi ichokwadi - cheku gum inobatsira pamagetsi. Pamusana pekuti pakugadzira kushandiswa kwemapanga kunowedzera zvakanyanya, inomedzwa zvikuru. Salivha inokonzera kushungurudza asidi uye inokonzera kumira kwekudzivirira kuchengetedza kufamba kwayo kubva kumudumbu kusvika mukati. Vatsvakurudzi veK King's College muLondon vakawana kuti avo vakatsvaga chewing gum nguva dzose kwehafu yeawa mushure mekudya kwete kwete chete mazino akadzivirirwa kubva pakuora mazino, asiwo zvakanyatsodzivirira kudzoka kwezvokudya uye asidi kusvika pachigamba. Saka iwe unogona kutarisa cheku gum nenzira yepamutemo yekurwisa kupisa kwemwoyo.
Kudzivirirwa kune otitis media yepakati nenzeve
Izvozvi "ropafadzo", inowanzoitwa nevana vaduku, avo vanowanzotambura nemarwadzo anorwadza bhakitiriya. Asi masayendisiti kubva kuunivhesiti yeFinland akawana kuti hutachiona hwekunzwa hunogona kudzivirirwa nyore nyore kana kuchera gum usina shuga uye ne xylitol. Anokwanisa kubudirira kukunda kwete chete nekuora kwezino uye mabhakitiriya ari munharaunda yemuromo, asiwo nepneumococci, iyo inokonzera kuvhiringidza kwepakati chenzeve.
Kugadzirisa koriori
Vatsvakurudzi veAmerica vakapedzisa kuti shuga yekusveta isina shuga inogona kubatsira kurerutsa uremu kuburikidza nekuderedza calorie kudya. Chidzidzo chacho chaisanganisira varume nevakadzi 35 vane utano hwakanaka avo vaifanira kutsvaira chese gum kwemaminitsi makumi maviri vasati vadya, uyezve kavirizve nguva isati yasvika. Migumisiro yakaratidza kuti vose vatori vechikamu vaidya 67% zvishoma maekoriyamu nevanodya kudarika zvavakamboita kare. Uye, aya makorikori haana kupiswa kwezuva, asi akachinjwa kuva simba rakachena - saka muviri wose wakagamuchira 5% mamwe simba. Masayendisiti anotenda kuti kuwanikwa uku kunogona kushandiswa zvinobudirira kurwisa kuneta.
Kuwedzerwa kukwanisa kudzidza
Mumwe purofesa payunivhesiti yeGermany akauya kumagumo ekufambisa chekuita zvakafanana nekurongwa kwekuyeuchidza muuropi nekukurumidza. Izvi zvinokonzerwa nekuti uropi huri nani kupa ropa uye masero machena kuwana mamwe oxygen apo masaya ari kushanda. Kudzidza, kwakaitwa nevana kubva kune zvikoro zvakasiyana, kwakaratidza kuti kukanganisa, kubvuma uye kukwanisa kubata nepamusoro kwakawedzera ne20% kana kutsvaga gum.
Mune imwe dzidzo, masayendisiti akaratidza kuti chewing gum inovandudza kubudirira kwemasvomhu. Mukuedza, 108 vadzidzi kubva kune makore 13 kusvika ku16, avo vakatsvaga gum mune zvidzidzo zvemasvomhu, vakatora chikamu. 14 masvondo gare gare, mhinduro yekuratidza yakaratidza kuti avo vakatsvaga gum vakaratidza zvikamu zvitatu zvepamusoro kupfuura zvese. Mukuwedzera, vaongorori vakaona kuti "kutsva" vana vanoda nguva shoma yokuzorora uye ivo vasati vasvika pakudzvinyirirwa.
Kudzivirira kwezviitiko
Kazhinji kacho, paanenge agere pabhiri kwenguva yakareba, mutyairi anotonha nemhaka yekuderedza kukuru mukutora kwayo. Nhamba idzi dzinotaura zvakajeka: njodzi yechina yega yega inokonzerwa nekuneta, kusatarisira, kana kupera kwenguva pfupi kwekufungidzirwa kwevatyairi. Uye kana ukadhakwa musati rwendo rurefu rwekofi - zvingave zvinobatsira munyaya iyi here? Sipanishi masayendisiti anobva kuYunivhesiti yeZaragoza akawana imwe, yakagamuchirwa uye yakanakisisa nzira-yekucheka panguva yekucheka gum. Izvo, kunze kwekuzorodza mweya, inoita kuti uropi hurambe huchishanda, zvichiita kuti kuwedzerwa maitiro uye kukwanisa kuita zvakakurumidza. Somuenzaniso, munguva yeHondo yeKorea, mauto eAmerica aive nemafuta chaiwo ekucheka gum kuitira kuti aite seanenge aisa pfungwa.
Kubatsira vane chirwere cheshuga
Nhasi, mamiriyoni evanhu vanotambura nechirwere cheshuga uye vanomanikidzwa kugovera muviri wavo ne insulini zuva nezuva kuti vapone. Nokudaro mubvunzo: "Sei insulini isina kupiwa semapiritsi?" Uye mhinduro, zvinosuruvarisa, haisi kutendera vanhu vanovimba ne insulin nokuda kwechikonzero chakajeka chokuti insulini inoparadzwa pakarepo mumatumbo emimba. Robert Dale, chigadzirwa chemakemikari paYunivhesiti yeSyracuse, akakumbira chibvumirano che chewing gum chinorwisa shuga. Mhedziso yake ndeyokuti mucheche wake chaiwo wekutavira vitamini B12 anosungira puroteni iri mune saliva. Iyi proteine ine simba rekudzivirira mavitamini kuora mwoyo. Musayendisiti akabatanidza insulin ne vitamin B12, uye akaedzawo kuongorora mumakonzo akaratidza kuti izvi zvinogona chaizvoizvo kuunza insulini kuropa. Masayendisiti anotaura kuti iyi yekucheka gum inonyanya kukodzera kuvanhu vane chirwere cheshuga uye ino inova neramangwana rakanaka.
