Akukho nasinye isiqhamo esinamandla okomfuziselo njengerharnati. Izibhalo zonqulo ziyayincoma njengokutya okunika ubomi kwaye iintsomi zamaGrike ziyichaza njengokutya koothixo. Namhlanje, izazinzulu zibonakalisa impembelelo yogcino lwempilo yerharnati kwintsebenziswano yezinto ezahlukeneyo zezityalo zesibini.
Irharnati - uphawu lobomi
Irharnati ibambe indawo ekhethekileyo phakathi kweziqhamo kangangamawaka eminyaka. Ngokuphindaphindiweyo iBhayibhile ibhekisela kwiimbewu ezininzi ezinencindi ezingaphakathi njengomfuziselo wokuchuma.
KwiKoran, irharnati ihlonitshwa “njengesiqhamo separadesi”. EMpuma, igqalwa njengomfuziselo wokungafi yaye kwiGrisi yamandulo yayigqalwa njengokutya koothixo.
Ngoku, ngoku, zonke ezi ndumiso zinikwe isiseko senzululwazi. Enyanisweni, impilo yethu inokuzuza kuphela kwiipropathi "ezinobomi" zeerharnati.
Ukubunjwa okukhethekileyo kwe-biochemical kwesi siqhamo kuye kwabangela umdla wonyango. Ngenxa yokuba irharnati ibonakaliswe njengenye yemithombo emikhulu ye-antioxidants kunye nokukhusela okunamandla kwi-radicals yamahhala ebangela izifo.
Phakathi kwezinto ezikhuthaza impilo yezityalo zesibini (i-phytonutrients), i-antioxidant flavonoids kunye ne-tannins kufuneka ikhankanywe ngokukodwa. Ukongezelela, kukho ukugxila okuphezulu kwe-vitamin C, i-potassium, kunye ne-pantothenic acid (i-vitamin B5).
Ukukwazi ukunciphisa uxinzelelo lwe-oxidative emzimbeni womntu kwenza ukuba ube sisixhobo sendalo esisebenzayo ngokuchasene nezifo ezivuthayo ezinjengomhlaza, isifo samathambo, kunye nesifo sentliziyo.
Uphononongo lubonise ukuba iziphumo ze-antioxidant ze-flavonoids kwijusi yerharnati zinamandla aphindwe kathathu kumhlaza kuneti eluhlaza. Oku kufunyanisiweyo kubangele iJenali yezoLimo kunye neChemistry yokutya ukuba ibhengeze ijusi yerharnati yeyona ncindi isempilweni ngo-2008.
Uphononongo olutsha oluvela eCarlifonia mva nje lubonise ukuba izithako ezisebenzayo kwirharnati zinokuyeka ukubunjwa kweemetastases kumhlaza wamabele.
Irharnati - uphando lomhlaza ngokunyuka
Uvavanyo lwebhubhoratri luye lwaqinisekisa ngokuphindaphindiweyo i-cytotoxicity yeerharnati. Izinto ezisebenzayo zezityalo zesibini (ingakumbi i-ellagic acid, kunye ne-luteolin) kuthiwa ziyakwazi ukutshabalalisa iiseli zomhlaza.
Uvavanyo lwezilwanyana oluhambelanayo lubonise ngokucacileyo ukuba ukondla irharnathi isicatshulwa kuthintela ukukhula kwethumba kwimiphunga, ulusu, ikholoni kunye nomhlaza wesinyi.
Ingqwalasela yezenzululwazi ukuza kuthi ga ngoku ijolise ikakhulu ekusebenzeni kwepomegranate extract ngokuchasene nomhlaza wedlala lesinyi.
Ngethuba lenkqubo yophando lweenyanga ze-18 kwiYunivesithi yaseJohns Hopkins eBaltimore, eU.SA, kwaboniswa ukuba i-PSA ephakamileyo (i-prostate-specific antigen) inqanaba kwizifundo zokuvavanya ezithatha i-pomegranate extract ngendlela yeepilisi zawa. Ijusi yerharnathi kuthiwa inefuthe elifanayo kwindlela yomhlaza webele.
Ijusi yerharnathi ibulala iiseli zomhlaza kwaye inciphisa ukudumba
Umhlaza wamabele ngokungathandabuzekiyo ngowona mhlaza ufunyaniswa uxhaphake kwabasetyhini kumazwe asentshona.
Ukusebenza kwezithako ezintathu ezithile (ikakhulu i-ellagic acid) kwincindi yerharnati ngokuchasene ne-prostate cancer metastasis ikhokelele izazinzulu kwiYunivesithi yaseCalifornia Riverside ukuba ziqikelele ukuba okufanayo kunokuba yinyani kunyango lomhlaza wamabele.
Iingcali zenzululwazi zithelekisa iziphumo ze-1% kunye ne-5% yesisombululo se-pomegranate juice kwiiseli zomhlaza webele kunye neeseli eziphilileyo.
Isiphumo sovavanyo lwaselabhoratri siyamangalisa: kwanesisombululo sepesenti esinye sazisa ukukhula kweeseli zomhlaza kuma ngxi kwiiseli zomhlaza wamabele.
Esi siphumo sinokunxulunyaniswa nokunyuswa kwe-gene expression, echasene neenkqubo ze-metastatic. Ngale ndlela, iiseli ze-tumor zithintelwa ukuba zisasazeke kwiithishu ezijikelezileyo kwaye zisasazeke kuwo wonke umzimba.
Ukongeza, isisombululo sejusi ye-1% yerharnati sicinezele ukuncamathelwa kweeseli zomhlaza kwizicubu zethambo.
Abaphandi ekugqibeleni bazuze impumelelo kuphando lomhlaza webele kunye nesisombululo seepesenti ezintlanu. Kolu gxininiso, ukukhula kweeseli zomhlaza akuzange kumiswe kuphela, inxalenye enkulu yeeseli zomhlaza ezikhoyo zabulawa.
Ngokuhambelana nomlo wokulwa neeseli zomhlaza ngejusi yerharnati, abaphandi baye babona impembelelo yayo yokuchasana nokudumba. Ngakolunye uhlangothi, izisombululo zanciphisa umsebenzi we-pro-inflammatory (pro-inflammatory) cytokines kwaye ngexesha elifanayo landisa inani le-cytokines elichasayo (i-anti-inflammatory).
IiCytokines ziiproteni ezilawulayo (iipeptides) ekudibaneni kwazo kubalulekile ekuphenduleni amajoni omzimba ngokuchasene neenkqubo ze-pathological ezibandakanya ukudumba kunye ne-metastases.
Izithako ezisebenzayo zendalo ezichasene nomhlaza, ezifana nezo zifumaneka kwierharnati, ngoko ke zimele enye indlela ethembisayo kumachiza ekhemikhali okanye inokuxhasa ubuncinci unyango oluqhelekileyo lomhlaza ngendlela yendalo.
Irharnati kunye neSoy: Isebenza kunye ngokuchasene nomhlaza wamabele
Uphando lubonise ukuba ayisosithako esisebenzayo kwirharnati esinoxanduva lokuchasa umhlaza, kodwa yintsebenziswano phakathi kwezithako ezizimeleyo ezigxininiswe kwijusi yerharnati okanye isicatshulwa serharnati.
Iglasi enye yejusi yerharnati ngosuku inokuba luncedo ekuthinteleni umhlaza wamabele. Ipesenti enye yoxinzelelo lwejusi yerharnati esetyenziswe kuphononongo lomhlaza wamabele ilingana neeglasi ezintathu zejusi yerharnati.
Ukunyuka okungaphezulu kokuthintela umhlaza wamabele kunye nokuhamba nonyango lomhlaza webele kunokufezekiswa ngokudityaniswa kwerharnati kunye nesoya.
I-Soy iqulethe i-phytoestrogen genistein, ekwayinxalenye yeqela lezinto zezityalo zesibini kwaye inokunqanda ukukhula kwethumba elixhomekeke kwihomoni.
Ngokutsho kophononongo lwakutsha nje, udibaniso lwee-phytochemicals ezivela kwierharnati kunye nesoya zisebenza ngakumbi ngokuchasene neeseli zomhlaza webele kunokuba zitye zombini ngokwahlukeneyo. Ekubeni ijusi yerharnati ifumaneka unyaka wonke kwaye iGenistein nayo inokuthatyathwa njengesongezo sokutya, abafazi banokuthatha ezi zithinteli zibini zomhlaza wendalo ukukhusela umhlaza ngokulula kwaye bayonwabele ngaxeshanye!
Xa kuziwa kwi-soy, nangona kunjalo, kufuneka uqaphele ngokubanzi umgangatho we-organic, kuba ngoku kukho ezininzi iimveliso zesoya eziguqulwe ngokwemfuza kwimarike.
