Isibonelo esihle sokudla okuyimpikiswano ngamafutha kakhukhunathi. Imvamisa iyanconywa ngabezindaba, kepha abanye ososayensi bayangabaza ukuthi iphila ngokulingana.

Ikakhulukazi ithole i-rap embi ngoba iphezulu kakhulu emafutheni agcwele. Kepha ucwaningo olusha lubonisa ukuthi amafutha agcwele akuyona impilo njengoba bekukholelwa phambilini.

Ngabe uwoyela kakhukhunathi uwukudla okungenamsoco okugcwala umthambo noma uwoyela okupheka onempilo ngokuphelele? Lo mbhalo ubheka ubufakazi.

Uwoyela Kakhukhunathi Unokwakheka Okuhlukile Kuka-Fatty Acids

Uwoyela kakhukhunathi uhluke kakhulu kwamanye amafutha amaningi okupheka futhi uqukethe ukwakheka okuhlukile kwamafutha acid.

Ama-acid anamafutha acishe abe ngu-90%. Kepha uwoyela kakhukhunathi mhlawumbe uhlukile kakhulu kokuqukethwe kwawo okuphezulu kwe-fat eligcwele i-lauric acid, elenza cishe u-40% wokuqukethwe okuphelele kwamafutha ().

Lokhu kwenza uwoyela kakhukhunathi umelane kakhulu ne-oxidation lapho kushisa kakhulu. Ngalesi sizathu, ilungele kakhulu izindlela zokupheka ezishisa kakhulu njengokuthosa ().

Uwoyela kakhukhunathi ucebe kakhulu ngama-acid acid aphakathi nendawo, aqukethe cishe i-7% ye-caprylic acid ne-5% capric acid ().

Iziguli ezinesithuthwane ekudleni kwe-ketogenic zivame ukusebenzisa la mafutha ukwenza i-ketosis. Kodwa-ke, uwoyela kakhukhunathi awulungele le njongo njengoba unomphumela omubi we-ketogenic (, 4).

Ngenkathi i-lauric acid ivame ukubhekwa njenge-acid-chain chain fatty, ososayensi bayaphikisana ukuthi ngabe lolu hlu lufanele yini.

Isahluko esilandelayo sinikeza ingxoxo eningiliziwe ye-lauric acid.

Uwoyela kakhukhunathi ucebile ezinhlotsheni eziningana zamafutha agcwele okungajwayelekile ukuthi angavamile. Lokhu kufaka phakathi i-lauric acid kanye ne-chain-chain chain fatty acids.

Uwoyela Kakhukhunathi Ucebile Nge-Lauric Acid

Uwoyela kakhukhunathi uqukethe cishe i-40% ye-lauric acid.

Uma kuqhathaniswa, amanye amafutha amaningi okupheka aqukethe amanani wokulandela kuphela. Okuhlukile ngamafutha esundu kernel, ahlinzeka ngama-lauric acid angama-47% ().

I-Lauric acid iphakathi nendawo phakathi kwama-acid-chain and long-chain chain fatty acids.

Ngenkathi ivame ukubhekwa njenge-chain-medium, iyagaywa futhi ihlanganiswe ngomzimba ngokuhlukile kuma-acid acid we-medium-chain futhi ifana kakhulu ne-fatty chain fatty acids (4,,).

Ucwaningo lukhombisa ukuthi i-lauric acid inyusa amazinga egazi e-cholesterol, kepha lokhu kubangelwa kakhulu ukwanda kwe-cholesterol eboshwe kuma-lipoprotein aphezulu (HDL) (,).

Ukwanda kwe-cholesterol ye-HDL, okuhlobene ne-cholesterol ephelele, kuhlotshaniswe nengozi encishisiwe yesifo senhliziyo ().

Uwoyela kakhukhunathi ucebile ngokuhlukile kwi-lauric acid, amafutha angavamile agcwele okubonakala enza ngcono ukwakheka kwama-lipids egazi.

Uwoyela Kakhukhunathi Ungathuthukisa Ama-Lipids Egazi

Ucwaningo lukhombisa ukuthi ukudla uwoyela kakhukhunathi njalo kuthuthukisa amazinga e-lipids ajikeleza egazini, okungahle kunciphise ubungozi besifo senhliziyo.

Ucwaningo olulodwa olukhulu, olulawulwa ngokungahleliwe kubantu abadala abaphakathi kweminyaka engama-91 bahlole imiphumela yokudla amagremu angama-50 kawoyela kakhukhunathi, ibhotela noma amafutha omnqumo ayizintombi nsuku zonke inyanga ().

Ukudla kukawoyela kakhukhunathi kukhulise kakhulu i-cholesterol “enhle” ye-HDL, uma kuqhathaniswa nebhotela kanye namafutha omnqumo ayengeyona intombi.

Ngokufanayo namafutha omnqumo ayintombi nto, uwoyela kakhukhunathi awuzange wandise i- “bad” LDL cholesterol ().

Olunye ucwaningo kwabesifazane abanesisindo sokukhuluphala esiswini lwathola ukuthi uwoyela kakhukhunathi wenyusa i-HDL futhi wehlisa isilinganiso se-LDL ukuya ku-HDL, kanti uwoyela wesoya ukhuphule inani kanye ne-LDL cholesterol wehla ne-HDL ().

Le miphumela iphikisana ngandlela-thile nezifundo ezindala ezibonisa ukuthi uwoyela kakhukhunathi uphakamise i-cholesterol ye-LDL uma uqhathanisa nowoyela we-safflower, umthombo wamafutha we-polyunsaturated, yize ungawukhulisanga njengebhotela (,).

Sezihlanganisiwe, lezi zifundo zikhombisa ukuthi uwoyela kakhukhunathi ungavikela izifo zenhliziyo uma uqhathaniswa neminye imithombo yamafutha agcwele, njengebhotela kanye namafutha wesoya.

Kodwa-ke, abukho ubufakazi bokuthi kuthinta izindawo zokugcina ezinzima njengokuhlaselwa yinhliziyo noma unhlangothi.

Ucwaningo lukhombisa ukuthi uwoyela kakhukhunathi ungakhuphula amazinga e-cholesterol “enhle” ye-HDL, ehlobene ne-cholesterol ephelele, enganciphisa ingozi yesifo senhliziyo.

Uwoyela Kakhukhunathi Ungakusiza Ukwehlisa Isisindo

Kunobunye ubufakazi bokuthi uwoyela kakhukhunathi ungakusiza wehlise isisindo.

Ocwaningweni lwabesifazane abangama-40 abanesisindo sokukhuluphala esiswini, uwoyela kakhukhunathi wehlise umjikelezo wesinqe uma kuqhathaniswa nowoyela wesoya ngenkathi futhi wenza ngcono ezinye izimpawu zempilo ().

Olunye ucwaningo olulawulwayo kwabesifazane abangu-15 luthole ukuthi uwoyela kakhukhunathi oyincasakazi unciphise isifiso sokudla uma kuqhathaniswa namafutha omnqumo ayintombi nto, lapho engezwa esidlweni sasekuseni esixubekile ().

Lezi zinzuzo kungenzeka kungenxa yama-acid fatty aphakathi nendawo, angahle aholele ekwehleni okuncane kwesisindo somzimba ().

Kodwa-ke, ososayensi baveze ukuthi ubufakazi obuku-chain chain enamafutha acid abunakusetshenziswa kuwoyela kakhukhunathi ().

Ngaphandle kobufakazi obuthembisayo, ucwaningo lusenomkhawulo futhi abanye abacwaningi babuza izinzuzo zokwehla kwesisindo samafutha kakhukhunathi ().

Izifundo ezimbalwa ziphakamisa ukuthi uwoyela kakhukhunathi unganciphisa amafutha esiswini futhi ucindezele isifiso sokudla. Kepha izinzuzo zangempela zokwehlisa isisindo zinempikiswano futhi zilinganiselwe kuphela.

Abantu Bomlando Abadla Ukhukhunathi Omningi Babenempilo

Uma amafutha kakhukhunathi engenampilo, ungalindela ukubona ezinye izinkinga zezempilo kubantu abazidla kakhulu.

Esikhathini esedlule, abantu bomdabu abathola iphesenti elikhulu lokudla kwabo ikhalori kusuka kukakhukhunathi babephilile kakhulu kunabantu abaningi emphakathini waseNtshonalanga.

AbaseTokelau, ngokwesibonelo, bathola ngaphezu kwama-50% ama-khalori abo kukakhukhunathi futhi babengabathengi abakhulu kunawo wonke wamafutha agcwele emhlabeni. AmaKitavans adle kuze kufike ku-17% wama-calories njengamafutha agcwele, ikakhulukazi avela kukakhukhunathi.

Bobabili laba bantu babonakala bengenayo iminonjana yesifo senhliziyo naphezu kokudla okunamafutha okuphezulu kakhulu futhi bebonke babe nempilo ehlukile (,).

Kodwa-ke, laba bantu bomdabu balandela izindlela zokuphila ezinempilo jikelele, badla izinhlanzi eziningi zasolwandle nezithelo, futhi badla cishe akukho ukudla okucutshunguliwe.

Kuyathakazelisa ukuqaphela ukuthi babethembele kukakhukhunathi, inyama kakhukhunathi nokhilimu kakhukhunathi - hhayi uwoyela osetshenzisiwe kakhukhunathi owuthenga ezitolo ezinkulu namuhla.

Noma kunjalo, lezi zifundo zokuhlola zikhombisa ukuthi abantu bangahlala bephilile ekudleni okunamafutha agcwele avela kukakhukhunathi (,).

Hlala ukhumbula ukuthi impilo enhle yalaba bantu bomdabu basePacific ikhombisa indlela yabo yokuphila enempilo, hhayi ukuthi badla kakhulu ukhukhunathi.

Ekugcineni, izinzuzo zamafutha kakhukhunathi cishe zixhomeke kwimpilo yakho yonke, ukusebenza komzimba kanye nokudla. Uma ulandela ukudla okungenampilo futhi ungazivocavoci umzimba, ukudla kakhulu uwoyela kakhukhunathi ngeke kukusize ngalutho.

Abantu baseziqhingini zasePacific abalandela ukudla komdabu badla ukhukhunathi omningi ngaphandle kokulimala empilweni yabo. Kodwa-ke, impilo yabo enhle kungenzeka ikhombise izindlela zabo zokuphila ezinempilo kunowoyela kakhukhunathi ngasese.

Okusemqoka

Yize izinzuzo zikawoyela kakhukhunathi zihlala zinempikiswano, abukho ubufakazi bokuthi ukudla uwoyela kakhukhunathi ngokulinganayo kuyingozi.

Ngokuphambene nalokho, ingahle ithuthukise iphrofayli yakho ye-cholesterol, yize okwamanje kungaziwa noma ngabe kunemiphumela ethile engcupheni yesifo senhliziyo.

Lezi zinzuzo zibhekiswe kokuqukethwe kwayo okuphezulu kwe-lauric acid, amafutha ahlukile agcwele okungajwayelekile kokudla.

Ekuphetheni, ukudla uwoyela kakhukhunathi kubonakala kuphephile futhi kungathuthukisa nempilo yakho. Kepha njengawo wonke amafutha okupheka, qiniseka ukuthi uwasebenzise ngokulinganisela.
