Umbuzo: Ingabe i-salmon yasendle ingilungele kangcono kune-salmon ephakanyiswe epulazini?

A: Inzuzo yokudla i-salmon efuywayo ngokumelene ne-salmon yasendle iphikisana kakhulu. Abanye abantu bathatha isimo sokuthi i-salmon ekhuliswe epulazini ayinakho umsoco futhi igcwele ubuthi. Kodwa-ke, umehluko we-salmon wasendle olinywayo uqhathaniswa nesilinganiso, futhi ekugcineni, ukudla noma yiluphi uhlobo lwe-salmon kungcono kunokungabikho nhlobo. Nakhu ukubhekisisa ukuthi lezi zinhlobo ezimbili zezinhlanzi zihlangana kanjani ngokudla.

Amafutha e-Omega-3

Kungenzeka ukuthi uzwile ukuthi i-salmon yasendle iqukethe inani eliphakeme lamafutha e-omega-3. Lokhu akulona iqiniso. Ngokuya ngemininingwane yakamuva kakhulu ku-database ye-USDA yokudla, i-ounce ezintathu ekhonza i-salmon yasendle iqukethe i-1.4g yamafutha we-omega-3 amade, kuyilapho usayizi ofanayo we-salmon ephakanyiswe epulazini iqukethe i-2g. Ngakho-ke uma udla i-salmon ukuthola amafutha amaningi e-omega-3 ekudleni kwakho, i-salmon ephakanyiswe epulazini yindlela okufanele uhambe ngayo.

I-Omega-3 kuya ku-Omega-6 Ratio

Enye inzuzo okushiwo ukuthi isalmon yasendle ngaphezu kokukhuliswa kwepulazi isilinganiso samafutha omega-3 kuya kumafutha e-omega-6 ngokuhambisana nempilo efanelekile. Lolu uhlobo lwesitatimende sobuqili, ngoba lolu hlobo lwesilinganiso lunomthelela omncane empilweni yakho-inani eliphelele lama-omega-3s liyisibikezelo esingcono sezempilo. Ukwengeza, uma isilinganiso samafutha e-omega-3 kuya ku-omega-6 besifanelekile, bekungaba ngcono kuma-saumoni afuywayo. Ku-salmon yase-Atlantic ephakanyiswe epulazini lesi silinganiso singama-25.6, kanti ku-salmon yasendle yase-Atlantic lesi silinganiso singu-6.2 (isilinganiso esiphakeme sikhombisa amafutha amaningi e-omega-3 kanye namafutha angaphansi kwe-omega-6).

Amavithamini kanye Nezimbiwa

Ukuze uthole izakhi ezithile ezifana ne-potassium ne-selenium, i-salmon yasendle iqukethe amanani aphezulu. Kodwa i-salmon efuywayo iqukethe inani eliphezulu lezinye imisoco efana ne-folate ne-vitamin A, kuyilapho amanye amazinga evithamini namaminerali afana phakathi kwalezi zinhlobo ezimbili. Sekukonke iphakethe lamavithamini namaminerali eliqukethwe yilezi zinhlobo ezimbili ze-salmon liyafana, ngazo zonke izinhloso nezinjongo.

Ukungcola

Inhlanzi, ikakhulukazi i-salmon, iwukudla okunomsoco kakhulu. Ukudla okuphezulu kwezinhlanzi ekudleni kuvame ukuhlotshaniswa nesifo esingelapheki. Eyodwa engeyinhle: Ubuthi nezinsimbi ezisindayo ezitholakala ezinhlanzini. Ngakho-ke kubantu abaningi abadla izinhlanzi, lokhu kudinga ukuhlaziywa kwezindleko / inzuzo. Kodwa lapho abacwaningi bebheka njengezinzuzo nezingozi zokudla izinhlanzi ngokuphathelene nokuchayeka kwe-mercury, isiphetho sasiwukuthi izinzuzo zidlula kakhulu izingozi, ikakhulukazi nge-salmon equkethe amazinga aphansi e-mercury uma kuqhathaniswa nezinye izinhlanzi eziningi.

Ama-biphenyls ama-Polychlorinated (ama-PCB) anenye ubuthi obungamakhemikhali obutholakala kusalmoni yasendle kanye nasekulimweni. I-salmon etshaliwe ngokuvamile iqukethe amazinga aphezulu ama-PCB kepha i-salmon yasendle ayikhululekile kulezi zinhlayiya. (Ngeshwa ama-PCB kanye noshevu ofanayo atholakala yonke indawo endaweni yethu angatholakala othulini endlini yakho.) Ucwaningo lwango-2011 olushicilelwe Isayensi Yezemvelo Nobuchwepheshe ibike ukuthi izici ezihlukene ezifana nobude besikhathi sokuphila kwezinhlanzi (i-chinook salmon iphila isikhathi eside kunezinye izinhlobo) noma ukuhlala nokudla eduze nogu kungaholela kumazinga e-PCB ku-salmon yasendle eduze kwaleyo etholakala ku-saumon efuywayo. Izindaba ezinhle ukuthi ukupheka izinhlanzi kuholela ekukhishweni kwamanye ama-PCB.

Ukuthatha: Ukudla noma yiluphi uhlobo lwesalmon kuzokuzuzisa. Ekugcineni, abantu baseMelika abazidli nje izinhlanzi ezanele futhi uma bekwenza, imvamisa izinhlanzi ezithile ezimhlophe ezibunjiwe ngomumo ongunxande, eshayiwe futhi ethosiwe. Eqinisweni, uma ubheka imithombo yamaprotheni ephezulu yaseMelika, inhlanzi ibonisa u-11 ohlwini. Isinkwa siba sesihlanu. Yebo, abaseMelika bathola amaprotheni amaningi ekudleni kwabo kusuka kwesinkwa kunezinhlanzi. Ungcono ngokudla i-salmon ekhuliswe epulazini esezingeni eliphezulu (ngaphandle kodayi abangeziwe ukuze uthuthukise umbala wezinhlanzi!) kunokungawadli nhlobo i-salmon. Kodwa-ke uma udla i-salmon njalo (ngaphezu kokuphindwe kabili ngeviki), khona-ke kungase kudingeke uthenge i-salmon yasendle ukuze unciphise ukuchayeka kuma-PCB amaningi.
