Indima yesengezo se-Omega 3 DHA ekondleni umzimba nomqondo
Izitayela zesimanje zezempilo zigcizelela kakhulu izithasiselo zokudla njengoba abantu befuna ukukhulisa amandla omzimba, ukusebenza kobuchopho, nokuphila kahle jikelele. Phakathi kwalesi simo esiguqukayo, ukunaka sekuzakhele kancane kancane entweni ethile esekamelweni lokudla eyaziwa ngokuba nomthelela omkhulu ezinhlelweni eziningi zomzimba. I-omega 3 DHA supplement ivelele ngoba i-docosahexaenoic acid (DHA) ingomunye wabalingisi abakhulu ekusekeleni inqubo ezahlukahlukene zomzimba. Ukufuna ukusebenza kahle kwenhliziyo, ukusebenza kangcono kobuchopho, nokusebenza kahle kwamangqamuzana kuvame ukuholela abantu ekucubunguleni ukuthi le fatty acid inegalelo kanjani empilweni ephelele. Le ngxoxo inikeza incazelo ejulile nge-DHA nendlela efakwa ngayo emkhubeni wempilo, ibheka ucwaningo lwakamuva nendlela olungase luthinte ngayo izinqumo zansuku zonke mayelana nokudla okunempilo.
Ukuqonda i-DHA: I-fatty acid ehlukile
I-DHA i-fatty acid ye-omega-3 enamaketanga amade etholakala ikakhulukazi kokudla okusuka olwandle. Umzimba uthembela kule nto yokudla ukwenza imisebenzi ethile yomzimba, kodwa awukwazi ukukhiqiza inani elanele uwedwa. Ukuze kuhlangatshezwane nalezi zidingo, abantu abaningi bathembele emithonjeni yokudla efana nezinhlanzi ezinamafutha noma ezinye izinhlobo zama-algae. Nakuba i-eicosapentaenoic acid (EPA) nayo iwuhlobo olwaziwayo lwe-fatty acid, i-DHA inezici ezikhethekile eziyihlukanisayo uma kukhulunywa ngokusekela ubuchopho, ukubona nokusebenza kwenhliziyo. Ngokungafani nama-omega-3 amafushane umzimba awakwazi ukuwaguqula kalula aphishekele emithonjeni yezitshalo, i-DHA kunzima kakhulu ukuyithola ngobuningi ngokudla okuvamile kuphela [1].
Ucwaningo luhlobanisa njalo ukuthatha i-DHA nezinzuzo eziningi eziqalela ekugugeni okunempilo kuya ekuphileleni ngokomzwelo. Ochwepheshe bagcizelela ukuthi ingasiza ekusekeleni ukuqina nokwakheka kwamamembrane wamaseli obuchopho. Lesi sici siyaqondakala kubantu abafuna ukugxila kangcono noma imizwa ezinzile. Ngasikhathi sinye, ubufakazi obusavela bubonisa ukuthi ingase ibe nomthelela ekulawulweni kwamafutha ezakhi zofuzo, okugqamisa ngokwengeziwe ubunkimbinkimbi bendima yayo emzimbeni womuntu. Sekukonke, imiphumela yayo ebanzi kanye nokungavami kwayo ekudleni okuvamile sekuholele kwintshisekelo enkulu ezithasiselweni.
Umehluko Obalulekile Phakathi kwe-DHA ne-EPA
Nakuba i-DHA ihlanganyela udumo lwe-omega-3 ne-EPA, kukhona umehluko obalulekile. I-EPA ivamise ukuhlonishwa kakhulu ngomsebenzi wayo ekulawuleni ukuphendula kokuvuvukala. Ochwepheshe abaningi bayibheka njengebalulekile ezimeni lapho ukuvuvukala komzimba wonke kuyinkinga enkulu. Ngakolunye uhlangothi, i-DHA igqamela ekugcineni ukwakheka nokusebenza kwamangqamuzana, ikakhulukazi ebuchopheni nasemehlweni. Futhi, i-retina inamazinga aphezulu kakhulu ale nto yokudla. Uma abantu begxile ekugcineni ukusebenza kobuchopho noma ekusekeleni ukubona ngokucacile, i-DHA ivame ukuvela njengozo oluyinhloko. Kokubili kubalulekile empilweni yonke, kodwa izinqumo ngokuthatha izithasiselo zivame ukuxhomekeka emigomeni ethile yezempilo [2].
Okuthakazelisayo wukuthi, eminye imikhiqizo kawoyela wezinhlanzi iqukethe ingxube elinganiselwe yalezi fatty acid zombili, kodwa izilinganiso ezingaphakathi zingahluka kakhulu. Uma isithasiselo sakhelwe ngokukhethekile ukuletha okuqukethwe kwe-DHA okuphezulu, lokho kuvuma ukubaluleka okukhethekile kwale fatty acid ekusebenzeni kobuchopho. Kubantu abafuna ukuqinisekisa ukuthi bathatha i-DHA eyanele ngaphandle kokuthembela kuphela kokudla kwasolwandle, ukuhlela umkhiqizo wokudla ukuze ugxile ku-DHA kungaba indlela ephumelelayo.
Impilo yobuchopho kanye ne-DHA
Inethiwekhi eyinkimbinkimbi yamaseli obuchopho incike ezakhiwo ezibalulekile ukuze igcine izindlela zokuxhumana ezisebenzayo. Phakathi kwalezi kukhona ama-fatty acid e-omega-3, kanti i-DHA ivame ukukhonjwa njengento ebalulekile ezinqubweni zokucabanga. Ezinganeni ezisakhulayo, i-DHA ibalulekile ekwakhekeni kobuchopho okusezingeni eliphezulu, yingakho nochwepheshe abaningi bezempilo begcizelela ukuthi abesifazane abakhulelwe nabancelisayo bafake ama-omega-3 anele ekudleni kwabo. Ngisho nangemva kobuntwana, abantu asebekhulile bangazuza ekuthatheni i-DHA njalo njengoba befuna ukugcina ubukhali bengqondo.
Ucwaningo lwakamuva luphakamisa ukuthi abantu abadla i-DHA eningi bangase bathole ukuthuthuka ekuphathweni kwemisebenzi yobuchopho, ukugxila, noma ukukhumbula. Nakuba indlela yokusebenza ingakacaci ngokuphelele, abacwaningi kudala bekubonile ukubaluleka kwale fatty acid ekubumbeni nokugcina uketshezi nokuba buthaka kwamamembrane wamaseli ohlelweni lwezinzwa. Le ndima yokwakheka ingasichaza isixhumanisi phakathi kokudla i-DHA eningi nokusekelwa okungenzeka kobuchopho [3].
Ukusebenza kweso nokusekelwa kombono
I-DHA yakha ingxenye enkulu yawo wonke ama-fatty acid akwi-retina. Uma ukudla okune-DHA kunganele, kungadala ukungalingani kokwakheka okubucayi kwamangqamuzana okwamukela ukukhanya emehlweni. Ngenxa yalokhu, ososayensi baphakamisa ukuthi i-DHA cishe inegalelo ekubukeni ngokucacile. Ucwaningo lokuthi ukushoda kwama-fatty acid kuthinta kanjani impilo yamehlo jikelele luthole ukuthi ukuthatha i-DHA njalo kungahambisana nokwakheka okuqinile kwe-retina, okuhlotshaniswa nokugcina umbono ongcono ngokuhamba kwesikhathi.
Nakuba izakhi zofuzo zomuntu, izifo asevele enazo, nezinto zemvelo kudlala indima enkulu ekugugeni kweso, amasu okudla ahlala eyingxenye eyinhloko yokuvimbela. Ukugcizelelwa okubekwe kwi-DHA ocwaningweni oluhlobene nombono kugcizelela umphumela wayo ongakuvikelayo. Njengoba izifundo ziqhubeka, ubufakazi buyaqhubeka nokusekela ukufakwa kwale fatty acid ohlelweni lokudla olubumbene lokunakekela amehlo.

Izinzuzo ezingaba khona zokuphila kahle kwenhliziyo nemithambo
Impilo yenhliziyo nemithambo yegazi iyinhlanganisela yezinto eziningi, okuhlanganisa umfutho wegazi olawulwayo, amazinga amafutha egazini (lipid profile) anempilo, nokuguquguquka kwemithambo. Eminye imibiko iphakamisa ukuthi i-DHA ingase ibe nendima ekugcineni amazinga ajwayelekile e-triglycerides, ngaleyo ndlela isize abantu banakekele i-lipid profile enhle. Nakuba kokubili i-DHA ne-EPA sekudonse ukunaka ngenxa yomthelela kuhle kwenhliziyo, ucwaningo lweminyaka yakamuva lugxile eminikelweni ethile ye-DHA. Kucatshangwa ukuthi le fatty acid ethile ingase isebenze kangcono kune-EPA ekuthuthukiseni ezinye izinkomba, njengokuthuthukisa ukuncipha-nokunwebeka kwemithambo.
Enye inzuzo engaba khona ukuthi ukudla i-DHA ngokwanele njalo kungasiza ekulawuleni izinkomba zokuvuvukala. Ukuphendula kokuvuvukala okuzinzile kungasiza ekugcineni izindonga zemithambo yegazi ziphilile. Ukugcinwa kwesikhathi eside kokuguquguquka kwemithambo kungaholela ekutheni igazi ligeleze kangcono nokuthuthwa komoya-mpilo emzimbeni wonke. Nakuba kungekho nto eyodwa yokudla engakuqinisekisa ukuvikelwa ngokuphelele ezinkingeni zenhliziyo nemithambo, ukusebenzisa izinzuzo ze-DHA kuyisinyathelo abantu abaningi abasibona sifanele [4].
Indlela umzimba osebenzisa ngayo i-DHA
Lapho isemuncwe, i-DHA ifakwa emamembrane wamaseli ezicutshini ezahlukene zomzimba. Lokhu kufakwa kusiza ukugcina amamembrane ekwazi ukuvuleka nokuvaleka (fluidity), okuthinta ukunyakaza kwamangqamuzana namayoni phakathi kwamaseli. Ngokugcina amamembrane esesimweni esihle, le nto yokudla isekela ukuxhumana phakathi kwamaseli, ukuhanjiswa kokudla, nokuxhumanisa amaseli. Ezicutshini ezinemisebenzi ephezulu yokushintshisana kwamandla, njengobuchopho namehlo, indima ye-DHA igqamile kakhulu.
Ngenxa yokuthi umzimba womuntu awukhiqizi i-DHA eningi uwedwa, amaphethini okudla ahlanganiswe nezithasiselo ezifana nama-omega 3 capsules ahlala ebalulekile. Kubantu abaqaphela inani lamakhalori noma imingcele ekudleni, isithasiselo esifanele singagcwalisa izikhala ekudleni. Naphezu kokwanda kolwazi nge-DHA, kusabakhona ukudideka mayelana nokuthi yiziphi izinhlobo ezimuncwa kangcono nokuthi zisebenzisana kanjani nezinye izinto zokudla. Ukubonisana nochwepheshe bezokudla noma wezokwelapha mayelana nomthamo ofanele nohlobo lomkhiqizo kungasiza ukuqinisekisa indlela ephephile nephumelelayo.
Imithombo efanele kanye nokwehluka kwayo
Izinhlanzi ezinamafutha—ezifana nosalmon, mackerel, ne-sardines—zaziwa ngokuba ne-DHA eningi. Ukuzidla njalo kuyatuswa, kodwa imikhuba yokudla noma izinto umuntu azithandayo zingakwenza kube nzima lokhu. Abantu abangadli nyama yezilwane (vegetarian) noma abangadli lutho elivela esilwaneni (vegan) kwesinye isikhathi baphendukela ezithasiselweni ezenziwe kuma-algae ezinikeza i-DHA ngaphandle kokusebenzisa umthombo wezilwane. Empeleni, ama-algae olwandle angomunye wemithombo emikhulu ye-DHA ochungechungeni lokudla olwandle. Lapho izinhlanzi zidle lawa ma-algae, zigcina le fatty acid, bese zibe umthombo wayo kumuntu ngokudla kwasolwandle noma uwoyela okhishwe kuzo.
Ngesimo sama-omega 3 capsules, i-DHA ivame ukuvela ihlangene nezinye izinto ukusiza ukumuncwa kahle noma ukuhlinzeka ezinye izinto zokudla ezihambisanayo. Imikhiqizo ingase ifake ama-antioxidant angeziwe, njengavitamin E, ukusiza ukugcina uwoyela ungonakali. Izindlela zokukhiqiza zanamuhla zihlose ukunciphisa ukuvunda (oxidation), ngoba amafutha abolile angaphazamisa izinzuzo. Imikhiqizo ethembekile ivame ukuhlolwa kakhulu ukuze kuhlolwe izinto ezingcolisayo ezifana nezinsimbi ezisindayo. Lokhu kunakekela kuqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana nezinhloso zezempilo kunokwethula izinto eziyingozi.
Ukukhetha umkhiqizo osezingeni eliphezulu
Uma uqhathanisa imikhiqizo ehlukene, ukuqinisekisa ubucoceko (purity), amandla (potency), nekhwalithi kubalulekile. Amalabhorethri azimele kwesinye isikhathi ahlolela izithasiselo amazinga aphelele e-omega-3, izinga lokuvunda, nokuba khona kwezinto ezingcolisayo. Ukuthola imikhiqizo enezitifiketi ezivela ezinhlanganweni ezizimele kuwunye umgudu wokukhuthaza ukuphepha nekhwalithi. Kuyanconywa futhi ukubheka indlela umkhiqizo ohanjiswa ngayo. Abanye abantu bakuzwa ukukhathazeka kwesisu uma bethatha amafutha ngesimo solwelo, kanti abanye bathola ukuthi ama-softgels noma ama-capsule kulula ukuwafaka ekuphileni kwabo.
Ngaphezu kwalokho, ukufunda ilebula ngokucophelela kukhombisa inani elihlobene le-EPA ne-DHA. Nakuba eminye imikhiqizo ihlose inhlanganisela ephelele, eminye igcizelela isilinganiso esiphezulu se-DHA, esingaba sikhona kubantu abakhathazeke kakhulu ngobuchopho nempilo yamehlo. Intengo yodwa ayisoloko ibonisa ikhwalithi, ngakho ukuqinisekisa izinto ezilinganekayo—njengezinga le-DHA ngensiza ngayinye—kungcono ekulinganiseni inani lemali nomkhiqizo [5].
Uma unentshisekelo ngendlela yokunakekela ukukhulelwa yonke, qiniseka ukuthi ubheka i-athikili yethu ethi "Folic Acid with DHA: Understanding the Importance of Both Together" ukuze uthole ukuthi i-folic acid ene-DHA ingase isekele kanjani ukukhula komntwana esiswini.
Isifinyezo
Ukusetshenziswa kwe-omega 3 DHA supplement sekukhulile ngezizathu ezicacile. Ucwaningo olukhulayo lugcizelela iminikelo yale fatty acid empilweni yobuchopho, amehlo, nenhliziyo nemithambo, okumenza kube ukwengeza okuwusizo ezimpilweni zabantu abaningi. Nakuba abantu abaningi bethola i-DHA ethile ngokudla, izinselele zesimanje nezintandokazi zomuntu ngamunye zingaholela ekuthatheni okungavumelani. Isithasiselo esisezingeni eliphezulu sisiza ukuqinisekisa ukuthi umzimba uthola umthombo ozinzile odingekayo ukuze usebenze kahle.
Emhlabeni lapho ukushoda kokudla okunempilo kungaphazamisa ngokushesha amandla omzimba wonke, ukufaka i-DHA njalo kubonakala kuyisinqumo esihlakaniphile. Uma kuhlanganiswe nendlela yokuphila elinganiselayo, lesi sithasiselo singaba umlingani othembekile ohambweni oluya ekucaceni komcabango, empilweni yamehlo, nasekuzijwayeleleni imikhuba yokuphila enempilo eqhubekayo. Noma ngabe itholakala ezinhlanzini zasolwandle noma kuma-algae, izinzuzo zayo ezibanzi zifanele ukubhekwa kunoma yiliphi uhlelo oluphelele lwezempilo. Abathengi abahlakaniphile abanaka ikhwalithi yomkhiqizo, umthamo, nokusebenzisana okungenzeka nabanye omuthi bazibekela amathuba emiphumeleni engcono kakhulu, kuyilapho begcina indima ebonakalayo ekuzinakekeleni. Ngale ndlela, ukusebenzisa amandla ale fatty acid akusona nje isenzo sokudla, kodwa kuyitshalomali empilweni yesikhathi eside.
