Yintoni esiyayazi ngegum? Uhle "namozolila" amehlo ethu kwiivenkile, uyabathanda abantwana bethu kwaye ngamanye amaxesha siyazihlaziya xa kukho intlanganiso enkulu. Kodwa yintoni na le nto yokuhlafuna, inzuzo kunye nenzakalo kuthi thina nabantwana bethu bahlale bevulekile imibuzo. Kodwa oku akukona unyango olungenangqiqo.
Ukuhlafuna i-gum kwiindawo zoluntu ngokuqinisekileyo kuyahambelana nephimbo elihle, kodwa ngamanye amaxesha kuyimfuneko. Enyanisweni, ukuhlafuna i-gum kunokunikela okungaphezulu kokuphefumula kunye nokuzonwabisa. Kodwa ngaphambi kokuba uthethe nantoni na malunga neenzuzo zalo mveliso, kufuneka kuthethwe inqaku elilandelayo: i-chewing gum ingaba luncedo kuphela xa i-sugar-free and if consumption is not exceed 30 minutes per day.
Imbali yokuhlafuna i-gum
Kukholelwa ngokusemthethweni ukuba i-chewing gum yenziwa phakathi kwekhulu le-19. Ngomnyaka we-1869, uWilliam Example ukusuka e-Ohio wathola ilungelo lobunikazi lomkhiqizo wakhe, oyisisindo sokuhlafuna ngendlela yeplastiki. Le gum ifuna ikhefu ekhethekileyo efana ne-tar. Ukugqithisa okunjalo kwakubonakala kuncinci, kwada kwangoko kamva kwakungenakulungiswa kwaye kufakwe izibhengezo ezithandekayo neziqhelekileyo. Kwiminyaka emashumi mathandathu kuphela emva koko i-chewing gum yafumana ukubonakala kwangoku. U-American Walter Dimar wakwazi ukufumana ibhalansi ephakathi kwamacandelo alo: i-rubber ye-20%, i-sugar% engama-60 okanye i-substituted, i-19% yesiraphu yengqolowa kunye ne-1% ye-flavorings. Isalathisi esiyinhloko somgangatho wegum, eqinisweni, yayiye kwaye ihlala iyanamathela.
Enyanisweni, ukuhlafuna i-gum kwafika kubantu ngaphambili. Okanye - ekuqaleni kwexesha le-Neolithic. Abaphengululi be-Archaeologists baye bafumanisa amaqhinga amazinyo kwiincinci ze-resin. AmaGrike asendulo ayekhetha i-resin yemithi ye-coniferous, ngokungafani namaMaya, asebenzisa i-resin ye-wood resin.
Namhlanje, amabutho aseMelika axhobileyo aphuhlise uhlobo olutsha lwefom ye-chewing gum equlethe izinto ezichasene ne-antibacterial ezivumela amasosha ukuba 'aqhube' amazinyo awo ngqo ekulweni. Iintlobo zolu qulunqo zicacile - kuya kuba luncedo kubantu abaninzi abaxakekileyo babemi. Olunye uhlobo lokuqulunqwa kwezilwanyana zaseMelika ngu-chewing gum kunye nomxholo we-caffeine, okwazi ukugcina amasosha ngokumelana nexesha elide ukwenzela ukuba abazi ukukhathala okanye ukulala.
Ucoceko olongezelelweyo lomlomo womlomo
Ukuhlafuna i-gum yindlela efanelekileyo yokuthintela ukuxhomekeka. Ukusetyenziswa kwansuku zonke kwekhofi kunye newayini ebomvu, kunye nokutshaya kutshintsha umbala weeamel amathoni amaninzi. Kodwa sonke siyazi ukuba amazinyo angcolileyo ibonakaliso esibalulekileyo kwimeko yabo. Kuyinyani ukuba akukho nanye i-chewing gum "inokujamelana nayo" yedwa ngamathambo kumazinyo, kodwa le yinto eyongezelelweyo eyongezelelweyo yokulwa nayo.
ukuhlafuna i-gum isekela umlomo omanzi, ivuselela i-salivation, ngaloo ndlela inceda ukuhlawulela umphumo ongezantsi we-asidi kwi-koil ezinyo emva kokutya. Ngendlela efanayo, amazinyo ahlanjululwa ngokucwangcisa "iindawo zokutya" ezinqabileyo kwiibhanki elastiki. Bahlala banamathele kuwo, kwaye ngokwenene ezo zincinci zingenye yezimbangela eziphambili zokubambisa, ekugqibeleni zibhubhisa indawo ekhuselekileyo yezinyo. Asimele sikhohlwe ngokuphefumula. Ukuhlafuna i-gum kuyaqabula - oku kuqinisekile. Enyanisweni, le nkqubo iphelelwe ixesha.
Simele silumke ngokukhetha ukutshiza i-gum kubantwana bethu, ukuze bangabalimazi. Amazinyo abantwana abantwana abathinteka kakubi ngoshukela (ngamanye amaxesha kunokubonakala bumnyama kunye nokubola kwamazinyo obisi, ekugqibeleni ekugqibeleni iingxaki ezinzulu namazinyo asisigxina). Kuya kuba luncedo ukuba i-chewing gum esiyithengayo kubantwana ayinalo iswekile kwaye iyenziwa nge-fluoride kunye ne-xylitol. I-xylitol ekhusela ngokufanelekileyo ukubunjwa kweplate kunye ne-caries. Ukusetyenziswa kwamazinyo kunzima ukugqithisa.
Kubalulekile ukukhumbula ukuba akukho ukuhlafuna i-gum inokufaka endaweni yokuxubha amazinyo kunye ne-teethpaste - inzuzo kunye nenzakalo kunokubangela ukungqubuzana, kodwa into enye ayinakuphikiswa - kufuneka uqhube amazinyo akho nawuphi na. Iikaroti kunye namaapulo, kwakhona, aluncedo kule nto.
Ukuzinza kwe-immunity kwisigodlo somlomo
Iphunga elimnandi, okwenene, akuyona into enhle kakhulu engenzeka kuyo. Kodwa, ngethamsanqa, i-mint chewing gum iyayilwa ngokuphumelelayo nale ngxaki, iyancipha kwaye ihlukanise iphunga emlonyeni. Kuya kuba luncedo, nangona kunjalo, ukuba i-chewing gum iqukethe ibhaktheriya ye-lactic acid, inakekele ibhaltriya ekhoyo emlonyeni womlomo. Iinqununu ezinjalo zokunwebeka sele zikhona kwaye zithandwa kakhulu kumazwe athile. Ukongeza, ezinye i-chewing gum zenziwe nge-aluminium lactate, eyanciphisa kakhulu ukuphuma kumagundane kunye nokunciphisa. Olu khetho olukhethiweyo lwe-chewing gum - iingenelo zalo kubantu abaphethwe zizifo ze-periodontal, bavavanywa kwaye baqinisekiswa yiingcali.
Ukukhutshwa kwe-asidi engena kwi-oopopus
Oku kuyinyaniso - i-chewing gum inefuthe elizuzayo kwinkqubo yokutya. Ngenxa yokuba kwinkqubo yokuhlafuna imveliso yamathambo yanda kakhulu, ityiwe kakhulu. I-saliva isusa i-acid enobudlova kwaye ibangela ingcamango yokugwinya ukukhusela ukuhamba kwayo ukusuka kwisisu ukuya kwi-esophagus. Abaphandi kwi-King's College yaseLondon bafumene ukuba abo bafuna ukuhlafuna i-chewing gum rhoqo kwisigamu seyure emva kokungena nje kuphela amazinyo akhuselekileyo ekuphumeni kwezinyo, kodwa kwanokuthintela ngokufanelekileyo ukubuyela kokutya kunye ne-asidi kwi-esophagus. Ngoko unokuqwalasela i-chewing gum ngeendlela ezisemthethweni zokulwa nokutshabalalisa.
Ukukhuselwa kwi-otitis media kwindlebe ephakathi
I-otitis enjalo "ilungelo", ngokuqhelekileyo kubantwana abancinci, abahlala behlushwa yi-bacterial infections. Kodwa izazinzulu ezivela kwikoyunivesithi yaseFinland zifumene ukuba ukusuleleka kwintsholongwane kunokuthintela lula ukuba ufune i-gum ngaphandle kweshukela kunye ne-xylitol. Unako ukuphumelela ngokukhawuleza ukuhlangabezana nokubola kwezinyo kunye neebhaktheriya eziqulethwe emlonyeni womlomo, kodwa kunye ne-pneumococci, ebangela ukuvuvukala kwendlebe ephakathi.
Ukunciphisa ukondla kweekhalori
Abaphandi baseMerika baphetha ngelithi i-chewing gum engenawo ushukela ingakwazi ukulawula ukulawula ubunzima ngokunciphisa i-calorie. Uhlolisiso lwabandakanya amadoda namabhinqa angama-35 aphilileyo afune ukuhlafuna i-chewing gum imizuzu engama-20 ngaphambi kokutya kwasekuseni, kwaye emva kweentsuku ezimbini ngaphambi kokuhlwa. Iziphumo zibonise ukuba bonke abathathi-nxaxheba badla iikholori ezingama-67% ngaphantsi kokutya kunokuba babesenza ngaphambili. Kwaye, ezi khalori zazingatshitshisi usuku, kodwa zatshintshwa zibe ngugesi ococekileyo-ngoko umzimba wonke wanikwa amandla ama-5%. Iingcali zenzululwazi zikholelwa ukuba oku kufumaneka ukusetyenziswa ngokukhawuleza ukulwa nokukhuluphala.
Ukwandisa amandla okufunda
Unjingalwazi kwiyunivesiti yaseJamani yafika kwisigqibo sokuba ukunyakaza ukuhlafuna kufana neenkqubo zokukhumbuza inkumbulo kwisantya esiphezulu. Oku kubangelwa kukuba ubuchopho bungcono ukunikezelwa kwegazi kunye neeseli ezimpunga zifumana i-oksijeni xa iindawo zomhlathi zisebenza. Isifundo, esenziwa ngabantwana kwizikolo eziliqela, sibonise ukuba ukuxinwa, ukufumana umgangatho kunye nokukwazi ukukhumbuza kwenyuka ngama-20% xa ifuna i-gum.
Kwesinye isifundo, izazinzulu ziye zafakazela ukuba i-chewing gum iphucula umveliso wemisebenzi yemathematika. Kulo vavanyo, abafundi abangama-108 abaneminyaka engama-13 ukuya kwe-16 ubudala, abaye bahlaziya i-gum kwizifundo zeemathematika, bathatha inxaxheba. Kwiiveki ezili-14 kamva, iziphumo zokuvavanya zibonise ukuba abo bahlafuna i-gum babonisa iziphumo eziphezulu ezi-3% kunezinye. Ukongezelela, abahloli baqaphela ukuba "abantwana abafuna ukuhlafuna" badinga ixesha elincinci lokuphumla kwaye bengaphantsi koxinzelelo.
Ukuthintela izingozi
Ngokukhawuleza, xa uhleli evili ixesha elide, umqhubi uyanxinwa ngenxa yokunciphisa okukhulu ekugxininiseni. Iimanani zithetha ngokucacileyo: nganye yengozi yesine ibangelwa ukukhathala, ukungalindelekanga, okanye ukulahlekelwa kwexesha elifutshane loxinzelelo lomqhubi. Yaye ukuba unxila phambi kohambo olude lwekhofi-ngaba kuya kuba luncedo kulo mbandela? Ososayensi baseSpain baseYunivesithi yaseZaragoza bafumana enye indlela, eyamkelekileyo nangakumbi kakhulu-yokuhlafuna xa ifuna i-chewing gum. Ngaphezulu kokuphucula ukuphefumula, igcina ingqondo isasebenza rhoqo, ngaloo ndlela ikhulisa ingqalelo kunye nokukwazi ukusabela ngokukhawuleza. Ngokomzekelo, ngexesha leMfazwe yaseKorea, amabutho aseMerika axhotyiswe i-chewing gum ekhethekileyo ukwenzela ukuba afakwe ngokugqithiseleyo kunokwenzeka.
Ukunceda abantu abanesifo sikashukela
Namhlanje, izigidi zabantu zifumana isifo sikashukela kwaye zinyanzeliswa ukuba zinike umzimba wazo nge-insulin yonke imihla ukuze ziphile. Ngako oko umbuzo: "Kutheni i-insulin engekho njengepilisi?" Yaye, impendulo, ngelishwa, ayikho into eyenziwa ngabantu abaxhomekeke kwi-insulin ngesizathu esilula ukuba i-insulin ichithe ngokukhawuleza kwiphepha lesisu. URobert Dale, isazi samakhemikhali kwiYunivesithi yaseSyrause, uye wafaka isicelo se patent ngethambo lokufuna ukulwa nesifo sikashukela. Ingcamango yakhe kukuba kwi-chewing gum yakhe i-vithamini B12 ibopha kwiprotheni equlethwe kwi-saliva. Le prothini inokukwazi ukukhusela ukuchithwa kwe-vitamin. Izazinzulu zathintela i-insulin nge-vitamin B12, kwaye zenze iilingo kwiigundane ezibonisa ukuba oku kunako ukuhambisa i-insulin egazini. Iingcali zenzululwazi zithi le gum isilungele ngakumbi kubantu abanesifo sikashukela kwaye le nto inomxholo ozayo.
