Ngokuvamile, labo abadla i-tuna basetshenziselwa ukukhipha futhi balahle uwoyela otholakala emathinini. Ucwaningo olusha manje seluxwayisa ngokuthi kuzoba wudoti, uma kubhekwa ukuthi lo oyili empeleni ungukudla okuhle okuthi, phakathi kokunye, ukuxhumana nenhlanzi kuthuthukiswe no-Omega 3 novithamini D. ingabe i-tuna kuwumqondo omuhle ngempela? Sibuze "wethu" isazi sokudla.
Sesikutshelile ngephutha okungafanele neze ulwenze lapho udla ithini le-tuna, okungukuthi, ukhiphe bese uphonsa uwoyela kusinki noma eminye imisele. Isizathu, uma ungazi kakade, singatholakala ku-athikili elandelayo.
Funda futhi: Iphutha okungafanele neze ulenze lapho uvula ikani le-tuna
Kepha esikhundleni sokuyikhipha bese uyilahla esitsheni esikhethekile, ukuze ungachithi, singayidla ngezitsha zethu?
Ucwaningo ngamafutha e-tuna
Una ricerca, eyenziwa iSiteshi Sokuhlola se-Imboni Yokudla Okusemathinini (i-SSICA) egameni le-ANCIT (Inhlangano Kazwelonke Yezinhlanzi Nezinhlanzi ZaseTuna), ithi uwoyela we-tuna uwukudla okuhle futhi okuphephile, ngakho-ke akumele kumoshwe, ngoba kugcina iphunga, ukunambitheka nezimfanelo ze-organoleptic. Iphinde ithole i-Omega 3 noVitamin D kusuka ku-tuna.
Ukuqinisekisa lokhu, ucwaningo luhlaziye uwoyela womnqumo okhona emathinini angama-80 g we-tuna uwagcina emazingeni okushisa ahlukene ama-3 (4 °, 20 ° no-37 °) futhi wabona ukwehluka esikhathini esiyinkomba sezinyanga eziyi-13. Ukuhlaziywa kwenziwa ngokufanayo nakumafutha kuphela ahlanganiswe emathinini alingana nawo kodwa ngaphandle kwe-tuna.
Ngalesi sikhathi sesikhathi, kwenziwa ukuhlolwa kwe-oxidation, ukuhlaziywa kwezinzwa (i-organoleptic yombala, ukunambitheka nephunga) nokuhlaziywa kwephrofayili ye-asidi yamafutha.
Imiphumela ayikhombisanga ubukhona bezinguquko (babungekho ubufakazi bokuthi i-oxidation futhi ubukhona bezinsimbi abuzange bubaluleke). Ngokuphambene nalokho, uwoyela nawo "wathuthukiswa" ngokombono othile. Ukuhlala kuthintana ne-tuna isikhathi eside, kwacebiswa ngama-polyunsaturated fatty acids, ikakhulukazi Omega 3 (DHA) kanye ne- Vitamin D (cholecalciferol) okungenjalo bekungeke kube khona emafutheni omnqumo.
Ekuphetheni, lolu cwaningo luthi akumele sithathe uwoyela we-tuna njengodoti wokudla kodwa kufanele siwusebenzise njengesithako noma isithako ekuphekeni. U-Gastroenterologist no-Nutritionist uLuca Piretta uthe maqondana nalokhu:
"Ukulahla kungaba yihlazo, ngoba uma kuqhathaniswa nophethiloli wokuqala ucebiswa ngisho nengxenye ye-DHA ayithatha ezinhlanzini. Ingasaphathwa eyokuba khona kukaVitamin D ”.
Ngenkathi usokhemisi uFrancesco Visioli engeza:
“Kumele sifundise umthengi futhi siphakamise ukuthi lo oyili usetshenziswe ngendlela efanele nangokomnotho oyindilinga. Ukusetshenziswa kabusha okusheshayo kunjengesithako esisekhishini ”.
Ngabe u-oyela we-tuna osethinini ulungele ukudliwa ngempela?
Ngenxa yalokho, nokho, ucwaningo olwenziwe ngoyela we-tuna lwathunyelwa yiNational Association of Fish and Tuna Preservers, sasifuna nokuzwa omunye umbono, lowo isazi sokudla UFlavio Pettirossi.
Ngabe kunconywa ngempela yini ukuthi kudliwe uwoyela ovela kumathini we-tuna noma amaphakheji e-glass tuna?
Nakhu asitshele khona:
"Il tuna okufanele kukhethwe kungokwemvelo (okufanele igeziswe ngenxa yokuba khona kukasawoti osetshenziselwa ukugcina futhi okunganikeza ukugcinwa kwamanzi noma izinkinga uma uphethwe umfutho wegazi ophezulu) isizathu esiyinhloko ukuthi akwenzeki njalo ukwazi noma ukuqinisekisa ikhwalithi kawoyela kufanele kube yi-Ages. Ngaphezu kwalokho, uma ulandela ukudla okunamafutha amancane noma, ngokujwayelekile, ukudla okunama-khalori aphansi, ukwengezwa kukawoyela, noma ngabe kuncane, kungenza umehluko futhi kungeze amakhalori amaningi "
Futhi yisiphi iseluleko esingasinikeza labo abadla i-tuna emafutheni noma kunjalo?
“Uma ufuna ngempela ukudla tuna Kumafutha ngihlala ngincoma u-dngiyayikhipha futhi engeza kakhulu amafutha omnqumo ayizintombi njenge-condiment ngokwesisindo sokudla.Esinye isici esiyisisekelo ukukhetha umkhiqizo embizeni yengilazi ukuze ukwazi ukuthola ikhwalithi yomkhiqizo futhi ngaphezu kwakho konke okusha. Kulesi simo, ngihlala ngincoma ukukhetha izinhlanzi e-Italy ngakhoke oLwandle iMedithera ”.
