Inyama ebomvu, izinkukhu nezinhlanzi ziqukethe ama-amino acids, ushukela, kanye neprotheyini okuthiwa i-creatinine. Ukupheka, ikakhulukazi ngaphansi kwamazinga aphezulu okushisa, kucatshangwa ukuguqula lezi zinhlanganisela zibe ama-heterocyclic amines (HCA) nama-hydrocyclic aromatic hydrocarbons (PAH). Inani elikhulu lalezi zinhlanganisela ziye zahlotshaniswa nomdlavuza ekucwaningeni kokuqala.
Ucwaningo nge-Carcinogens kanye neCanscer
- Ucwaningo olwenziwa yi-National Institutes of Health, olwanyatheliswa encwadini ye-Cancer Research, lathola ukuthi inyama enobumba obomvu ehlotshaniswa nenengozi eyandayo ye-adenoma ye-colorectal, isilonda sesandulela ngculaza.
- Olunye ucwaningo luhlolisise ubudlelwane phakathi kokudla okudliwayo kwamaHCA kanye nama-PAH nomdlavuza we-pancreatic. Ababambiqhaza banikeze ulwazi mayelana nokudla kwabo okuvamile, inyama yokulungiselela (isb., I-stewed, ethosiwe, noma eboshwe / ehlongoziwe), futhi kaningi izinga lokudla inyama. Abacwaningi bathola ukuthi ukudla okwenziwe kahle kanye nezinyama ezingenamvubelo kungase kuhlotshaniswe nengozi enkulu yomdlavuza we-pancreatic.
- I-Prostate, Lung, Colorectal, ne-Ovarian Cancer Screening Trial ihlolisise ubudlelwane phakathi kwalezi zakhi zenyama nomdlavuza womdlavuza we-prostate besebenzisa i-questionnaire yokudla phakathi kwamadoda angu-29 361. Nakuba inyama yenani elidliwayo noma elibomvu noma elimhlophe elidliwayo lingavumelani nengozi yomdlavuza we-prostate, inyama enhle kakhulu yayihlotshaniswa nengozi enkulu yokwelapha i-prostate.
6 Inyama Ukulungiselela Amathiphu Ukuzama
Lezi zinhlanganisela zakhiwa ngaphakathi kwenyama, hhayi nje ebusweni, ngakho-ke awukwazi ukuziqeda ngokukhipha phezulu.
Kodwa abacwaningi bathola ukuthi ukulungiselela okuthile kanye namasu okupheka kunganciphisa ukwakheka kwalezi zakhi:
- Ukupheka nge-cherries: Abacwaningi baseMichigan State University bathola ukuthi ukwengeza i-cherries, ecebile kuma-antioxidants, emhlabathini owenziwe phansi ngaphambi kokuba kutholakale i-pan-frying kunciphise ama-HCA akhiqizwa cishe ngamaphesenti angama-69 kuya ku-78.5. Zama ukuxuba amakhilogremu angu-1 we-ground ground nge-1 indebe ye- cherry tart ngaphambi kokupheka.
- Cabanga nge-vitamin E: Ukwandisa i- vitamin E ekudleni kwatholakala ukuthi kuyanciphisa kakhulu ukubunjwa kwama-HCAs. Ezicwaningweni, ama-milligram angu-120 evithamini E powder ahlanganiswe ngama-3.5-ounce patties. Khuluma nomhlinzeki wakho wokunakekela oyinhloko, noma kunjalo, ngaphambi kokusebenzisa izithako (kufaka phakathi i-vitamin E) njalo.
- Engeza i-garlic, i-rosemary, ne-sage: Lezi zinhlayiya ze-antioxidant zingasiza ekuvimbeleni ukwakhiwa kwama-HCA nama-PAH. Zama ukwengeza ugarlic ochotshoziwe kanye ne-rosemary noma omusha noma omisiwe ukuze udla izingxube ngaphambi kokupheka.
- Pheka ngamafutha omnqumo: Amakhemikhali ama-phenolic emafutheni omnqumo anempahla e-antioxidant etholakale ukunciphisa ukwakheka kwama-HCAs nama-PAHs. Zama ukupheka ngamafutha omnqumo, noma usebenzise emanzini.
- Phuza itiye elihlaza ngesidlo sakho: I- Polyphenols itiye eliluhlaza lingasiza imizimba yethu ukuba ihlukane nama-carcinogenic compounds. Zama ukuphuza indebe yetiyi eluhlaza njalo, ikakhulukazi ngokudla okuqukethe inyama ephekwe. Ukuze uthole ulwazi oluthe xaxa, thola ukuthi ungaba kanjani itiye eluhlaza ukwandisa ama-antioxidants .
- Thola ezinye izindlela zokupheka. Zama ukusebenzisa izindlela zokupheka ezisekelwe ketshezi, njengokubilisa, ukuqhuma, noma ukuhamba. Uma sekufisa ukuphela komlilo, zama ukupheka inyama, izinkukhu kanye nezinhlanzi usebenzisa izindlela zokupheka ezisekelwe ngamanzi ukuze unciphise ama-HCA bese uziqeda kuhhavini noma kwi-grill. Qinisekisa ukuthi ususa ama-juice futhi ungawasebenzisi ukwenza i-gravy noma amanye amasoso, ngoba ama-juices akhiqizwa ngesikhathi sokupheka angase aqukethe amaprotheni akha ama-HCAs.
Amanye amathiphu? Hlanganisa inyama emanzini amancane ngaphambi kokupheka, udle inyama encane ebomvu, unciphisa ukusetshenziswa kwakho kwezilwane eziphethwe yi-nitrite (okubandakanya ukusikeka okubandayo, izinja ezishisayo, ubhekeni kanye nehhashi), amafutha amaningi, futhi ungadli inyama eshisa noma ngaphezulu- kwenziwa (Yebo, umhlabathi wenkomo, ingulube kanye nezinkukhu kufanele kuphekwe kahle ukuze ugweme ukudla okweshukela).

Ukuziphendulela: Ulwazi oluqukethwe kule sayithi luhloswe ngezinjongo zemfundo kuphela futhi aluthathi iseluleko, ukuxilongwa noma ukwelashwa ngudokotela olayisensi. Akuhloselwe ukumboza zonke izinyathelo zokuqapha, ukusebenzisana kwezidakamizwa, izimo noma imiphumela emibi. Kufanele ufune ukunakekelwa okusheshayo kwezokwelapha kunoma yiziphi izinkinga zezempilo bese uthintana nodokotela wakho ngaphambi kokusebenzisa enye imithi noma wenze ushintsho ohlelweni lwakho.
