Kwimeko yomhlaza wesibeleko, kwanokutshintshela ekudleni okunamafutha aphantsi kunye nokutya okungaguqukiyo kwe-omega-3 fatty acids ekumgangatho ophezulu kunokukhokelela ekuphuculeni. Kolunye uphononongo, le ndlela yacotha ukukhula kwamathumba edlala lengqula ngaphezu kwe-50% yezifundo zovavanyo ezaziza kwenziwa utyando lwesinyi.
I-Omega-3 fatty acids isebenza ngokuchasene nomhlaza wedlala lesinyi
Abaphandi abakhokelwa nguWilliam J. Aronson kwiSebe le-Urology kwiSikolo seMithi kwiYunivesithi yaseCalifornia-Los Angeles kutshanje baqhube isifundo kunye namadoda angama-55 aphethwe ngumhlaza wesifo seprotate. Isiphumo sophononongo sapapashwa kwi-intanethi yephephancwadi iCancer Prevention Research.
Uphononongo lubonise ukuba ukunciphisa isixa samafutha ekutyeni kunye nokutshintsha i-omega-6/omega-3 fatty ratio ngokuthanda i-omega-3 fatty acids kunokunciphisa umngcipheko wokukhula komhlaza wedlala lesidoda ngakumbi.
Ukutya okuqhelekileyo ngokuchasene nokutya okunamafutha aphantsi omega-3
Izigulana ezingama-55 zomhlaza wedlala lobudoda ebekufanele ukuba zisuswe idlala lengqula kwiiveki ezine ukuya kwezintandathu zakhethwa, kwaye ezingama-48 kuzo ziye zaluqhuba uvavanyo kwade kwasekupheleni. Isiqingatha samadoda satya ukutya okuqhelekileyo kwaseMelika, okuqulethe ama-40 ekhulwini eekhalori ezisuka kumafutha.
Umlinganiselo we-omega-6 fatty acids kwi-omega-3 fatty acids wawuyi-15 ukuya kwi-1. Esinye isiqingatha sezifundo zovavanyo zanikwa ukutya okunamafutha aphantsi okwenza kuphela i-15 ekhulwini yeekhalori zabo kumafutha. Ukongezelela, babefumana iigram ezintlanu zeoli yeentlanzi yonke imihla. Umlinganiselo we-omega-6-omega-3 emva koko utshintshele kwi-2 ukuya ku-1 ngokuthanda i-omega-3 fatty acids.
Ukutya okune-Omega-3 kunciphisa izinga lokwahlukana kweeseli zomhlaza
Omabini la maqela akugcine ukutya ebekunikwa kangangeeveki ezine ukuya kwezintandathu. Emva koko kwakhutshwa amadlala abo edlala lengqula. Abaphandi baphonononga izicubu zeprotate zamaqela omabini kwaye bafumana into emangalisayo:
Iiseli zeprotate kwiqela le-omega-3 zibonise ipateni eyahlukileyo ye-fatty acid kwi-membrane yeeseli zabo kuneqela eliqhelekileyo lokutya. Ngokuhambelana nokutya kwabo, i-omega-3 fatty acids yayiqokelele kwiinwebu zeseli ukuya kwinqanaba elikhulu. Kwangaxeshanye, abaphandi bakwazi ukujonga ukuba izinga lokwahlulwa kweseli yomhlaza kumadoda e-omega-3 yayingaphantsi kwesithathu kumadoda aqhelekileyo.
Izinga lolwahlulo oluphantsi - i-prognosis efanelekileyo
Umlinganiselo wokwahlula uchaza isantya apho iiseli zomhlaza ezahlulayo. Ukuphakama kwesantya sokwahlukana, ngokukhawuleza ithumba likhula, iphezulu ingozi ye-metastasis, kwaye kunokwenzeka ukuba umhlaza uya kuqhubeka emva kotyando. Ngenxa yoko, amazinga asezantsi okwahlukana akhokelela kuqikelelo olunethemba.
Igazi elivela kwizigulane ze-omega-3 lithintela ukukhula komhlaza
Ukutya okunamafutha aphantsi e-omega-3 kwaba neziphumo ezixhaphake kakhulu kwiiveki ezimbalwa bezisenziwa kangangokuba kwaneemvavanyo ze-vitro nge-serum yegazi yabantu abavavanywayo zivelise iziphumo ezincomekayo.
Izazinzulu zabeka iiseli zomhlaza kwityhubhu yovavanyo kunye neserum yegazi ye-omega-3 yamadoda kwaye yafumanisa ukuba le serum yodwa ikwazile ukunqanda ukwahlukana kweeseli zomhlaza. I-serum yegazi yokutya okuqhelekileyo kwamadoda yayingenayo impembelelo enjalo yokuthintela ukukhula kwiiseli zomhlaza.
Ngexesha lokupapashwa kwesifundo saseCalifornian, abaphandi bebengayazi indlela ethile yokwenza i-omega-3 fatty acids kwiiseli zomhlaza. Oku akuzange kuthathe isigqibo kwisigulana, kuba isiphumo sisodwa sisigqibo - nangaphandle kwengcaciso yokuba kwenzeke njani.
Nangona kunjalo, ingxelo yezazinzulu zeYunivesithi yaseWashington State yapapashwa kwi-Journal ye-Pharmacology kunye ne-Experimental Therapeutics ngo-Matshi 2015.
Abaphandi abakhokelwa nguNjingalwazi uKathryn Meier ngoku bakwazile ukucacisa indlela yokwenza ngokuthe ngqo i-omega-3 fatty acids ngokuchasene neeseli zomhlaza.
Indlela yokulwa nomhlaza ichaziwe
Oogqirha bafumanisa ukuba i-omega-3 fatty acids ibophelela kwii-receptors ezithile kwiiseli zomhlaza, ezitshintsha unxibelelwano lwesignali phakathi kweeseli. Xa i-omega-3 fatty acids ifakwe kwinto ebizwa ngokuba yi-FFA4 receptor (ekwabizwa ngokuba yi-"free fatty acid receptor 4"), ukukhula kweeseli zomhlaza kwanqanyulwa kwaye ukusasazeka kweseli kwacinywa.
UNjingalwazi Meier uyacacisa:
"Singabokuqala ukubhala le ndlela yokusebenza kwiiseli zomhlaza."
Ngoko ke kubalulekile ukuba i-omega-3 fatty acids - idibaniswe nokutya okunamafutha aphantsi kunye nokutya okunempilo - inokuthintela kakhulu ukukhula komhlaza.
Imifuno ye-omega-3 fatty acids
Kuphononongo lwaseCalifornia, izifundo zovavanyo zafumana ioyile yentlanzi njengomthengisi we-omega-3 fatty acids. Okwangoku, nangona kunjalo, kukho iindidi ezininzi zamalungiselelo eoli ye-algae yemifuno, umz. B. ukusuka kwindalo esebenzayo okanye i-Norsan, ebonelela nge-high-chain-chain omega-3 fatty acids (DHA kunye ne-EPA).
