Kungenzeka ukuba awuyazi nokuba yintoni i-monosodium glutamate kwaye awuzange uve igama layo. Okubi kwelinye icala, kuba usinika ukuqonda ukuba awuqhelekanga ukufunda iilebhile zeemveliso ozityayo. Enkosi ngokubaluleka kokuthathwa kwesondlo kwiminyaka yakutshanje, sifumanisa amacandelo okutya angaphilanga ngokupheleleyo. Ngokwengqiqo zinokutyiwa, kuba zonke iimveliso ezithengiswa kwiivenkile ezinkulu ziye zadlula kulawulo lomgangatho. Oko akuthethi ukuba kukho izithako ezingalunganga emzimbeni.
Yintoni i-monosodium glutamate?
I-Monosodium glutamate (MSG) yityuwa yesodium ye-glutamate. Iqulethwe ngamanzi, i-sodium, kunye ne-amino acid glutamate engabalulekanga, i-glutamate yenza kwi-taste receptors efanayo njengoko kwenzeka ngokwemvelo i-glutamate kukutya, kuquka iitumato, amakhowa, isosi yesoya, i-miso, itshizi endala kunye nenyama ephilisiwe.
I-MSG yenye yezongezo zokutya eziqhelekileyo ezizisa incasa emnandi (okanye umami) kwincasa yethu. Namhlanje isetyenziselwa ukuveliswa kokutya kwenziwa kwi-seaweed okanye, ngokuqhelekileyo, ukusuka kwi-fermentation ye-sugar beet, i-sugar cane okanye i-molasses.
Kukutya okupakishweyo, ikhowudi ye-MSG inokubandakanya "iprotein yemifuno ene-hydrolyzed," "isicatshulwa seprotheyini yemifuno," "i-yeast extract," "igwele elizenzekelayo," okanye "i-seasoning."
Ngokubanzi, sinokuthi luhlobo lwetyuwa olo yongeza incasa yokutya kusetyenzwe kwaye ukongeza Ikuvumela ukuba uzigcine zikwimeko entle iinyanga okanye iminyaka. Kwezinye iindawo yaziwa ngokuba yityuwa yaseTshayina, kuba inxulumene nokubonakala kwesifo sokutyela saseTshayina.
Kusenokwenzeka ukuba siya kuyifumana njenge "umami" yokongeza. I umami Yeyokungcamla okuhlanu okusisiseko, kunye nokukrakra, okuswiti, okumuncu, kunye netyuwa. Siyifumana ngokwemvelo ekutyeni okuthile okufana nenyama, iitumato, isipinatshi namakhowa. Kunoko, i-glutamate sisiphumo senkqubo yemichiza.
Ukungena kwiikhemikhali, i-monosodium glutamate yenziwe nge-78% yamahhala ye-glutamic acid, i-21% ye-sodium kunye ne-1% engcolileyo. Uyingcali kwi ukukhohlisa umzimba wethu, ukwenza ukuba ukholelwe ukuba ukutya kunencasa ngcono, kusempilweni kwaye kutyebile kwizondlo.
Kutheni kufuneka sikuphephe?
Nangona abanye abantu bebonakala benovelwano kwi-MSG, i-FDA ihlele isongezo sokutya njenge "yaziwa njengekhuselekile", isithi abantu abaninzi banokuyisebenzisa ngexabiso elifanelekileyo ngaphandle kokukhathazeka.
Uphononongo kwi-Journal of Headache and Pain yafumanisa ukuba i-MSG inegalelo kuphela ukwenzeka kwentloko ebuhlungu xa ilawulwa njengesisombululo se-high-concentration liquid, kwaye nezo zifundo azizange ziphosakele ngokwaneleyo izifundo ezingaboniyo kwizinto ezidlayo. Ngaphezu koko, olu phononongo lunqume ukuba umqobo wegazi-ubuchopho uthintela ukuthatyathwa kwenxalenye ye-glutamate xa idliwe ngamanani aqhelekileyo kwaye ngoko ayinayo impembelelo eyingozi ekusebenzeni kwengqondo. Ke ngoko, ithuba lokuba i-migraine yakho okanye inkungu yobuchopho ibangelwe yi-slurping ramen lincinci.
Sekunjalo, izazinzulu kwiYunivesithi yaseNorth Carolina zafumanisa ukuba abo batya kakhulu i-MSG babenayo amathuba amathathu okuba utyebe kakhulu kunabo abangazange badle, nangona ukufana nokusebenza ngokomzimba kunye nokutya kwekhalori yemihla ngemihla. Kubalulekile ukuqaphela ukuba uninzi lwabathathi-nxaxheba balungiselela izidlo zabo ekhaya ngaphandle kokuthembela kakhulu ekutyeni okuthengiswayo, uninzi lwe-MSG luvela kwizinongo abathe bongeza ekuphekeni kwabo.
Mhlawumbi, ukuvezwa okuphezulu kunako kuguqula ngokungalunganga imetabolism yamafutha kunye neecarbohydrates emzimbeni, kodwa uphando oluninzi luyafuneka ngaphambi kokuba kuthathwe izigqibo.
Kukho izifundo ezininzi eziqinisekisa ukuba ukuthatha i-monosodium glutamate kubangela ukungonwabi kwimpilo yethu njengentloko ebuhlungu, i-migraines, intlungu yesifuba, umlomo otshisayo, ukugungqa, ukuxhuzula kwemisipha, isicaphucaphu, i-allergies, i-anaphylaxis, i-epileptic, ukubila, ukudakumba, okanye ukungahambi kakuhle kwentliziyo.
Yityhefu yonakalisa inkqubo yethu ye-nervous kwaye ivuselela kakhulu ii-neurons ukusa kwinqanaba lokudinwa. Kunzima kakhulu ukungayisebenzisi, kuba ihlala ikhona kwiimveliso ezininzi, kodwa sinokunciphisa kakhulu ukuyithatha kwayo.
Zeziphi iimveliso ezihlala zikhona?
Indlela elula yokuphepha ukuyidla kukubheja kwiimveliso zendalo kunye nokuyeka ukutya okucutshungulweyo. Funda iilebhile zesondlo sayo nayiphi na imveliso egayiweyo efana neekuki, isonka, iziselo ezibandayo, iisosi, ukutya okukhenkcezisiweyo, iitshiphusi...
Ngamanye amaxesha iinkampani ziyayifihla kunye nezinye iikhompawundi ezinje ngeprotheyini eyenziweyo, ukutya kwegwele kunye nesondlo sayo, iprotein yesoya, okanye igelatin.
Ngokunokwenzeka, ukutya "okukhanya" okwenziwe ngestatshi, isiraphu yombona, isiraphu yerayisi, okanye ubisi oluyimpuphu nako kuneempawu zeglutamate.
