Yini ukuxhumana phakathi kweShrimp, Cholesterol, neNhliziyo Yezempilo?

Ukubuka konke
Eminyakeni edlule, izimfanzi zazibhekwa njengezinto ezingafuneki kubantu abanesifo senhliziyo noma ababheka izinombolo ze-cholesterol. Lokho kungenxa yokuthi ukuphakelwa okuncane kwama-ounces angu-3.5 kunikeza cishe ama-milligram angu-200 (mg) we-cholesterol. Kubantu abasengozini enkulu yesifo senhliziyo, lokho kufinyelela esabelweni sosuku lonke. Kubo bonke abanye abantu, u-300 mg ngumkhawulo.
Kodwa-ke, imfanzi iphansi kakhulu kumafutha esewonke, cishe i-1.5 gramu (g) ngokusebenza ngakunye futhi cishe ayinamafutha agcwele nhlobo. Amafutha agcweleyo ayaziwa ukuthi ayingozi kakhulu enhliziyweni nasemithanjeni yegazi, ngokwengxenye ngoba imizimba yethu ingayiguqula ibe yi-low-density lipoprotein (LDL), eyaziwa nangokuthi yi-cholesterol “embi”. Kodwa izinga le-LDL liyingxenye yalokho okuthonya ingozi yesifo senhliziyo yakho. Funda kabanzi ngezimbangela nobungozi besifo senhliziyo.
Okushiwo ucwaningo
Njengoba iziguli zami zivame ukungibuza ngezimfanzi ne-cholesterol, nginqume ukubuyekeza imibhalo yezokwelapha ngathola isifundo esimangazayo esivela eRockefeller University. Ngo-1996, uDkt Elizabeth De Oliveira e Silva nozakwabo bavivinya ukudla okususelwa kuzimfanzi. Abesilisa nabesifazane abayishumi nesishiyagalombili bondliwe ama-ounces ayishumi ama-shrimp - ahlinzeka cishe i-600 mg ye-cholesterol - nsuku zonke amasonto amathathu.Ohlelweni olujikelezayo, lezi zihloko zaphinde zaphakelwa ukudla kwamaqanda amabili ngosuku, okunikeza inani elilinganayo le-cholesterol, amasonto amathathu. Baphakelwa ukudla okuyisisekelo okunama-cholesterol amanye amasonto amathathu.
Ngemuva kokuphela kwamasonto amathathu, ukudla kwezimfanzi empeleni kwenyusa i-cholesterol ye-LDL cishe ngamaphesenti ayi-7 uma kuqhathaniswa nokudla okunamafutha aphansi. Kodwa-ke, yaphinde yandisa i-HDL, noma “okuhle” cholesterol, ngamaphesenti ayi-12 futhi yehlisa ama-triglycerides ngamaphesenti ayi-13. Lokhu kuveza ukuthi imfanzi ibe nomthelela omuhle ku-cholesterol ngoba ithuthukise i-HDL kanye ne-triglycerides ingqikithi yamaphesenti angama-25 ngentuthuko ephelele ngamaphesenti ayi-18.
Ukusikisela ukuthi amazinga aphansi e-HDL ahlotshaniswa nokuvuvukala okuphelele maqondana nesifo senhliziyo. Ngakho-ke, i-HDL ephakeme iyathandeka.
Ukudla kwamaqanda kuphume kubukeka kubi kakhulu, kushaya i-LDL ngamaphesenti ayi-10 ngenkathi kukhuliswa i-HDL cishe ngamaphesenti ayi-8 kuphela.
Okubalulekile
Iqiniso? Ubungozi besifo senhliziyo busekelwe ngaphezu kwamazinga we-LDL noma i-cholesterol ephelele. Ukuvuvukala kungumdlali omkhulu engcupheni yesifo senhliziyo. Ngenxa yezinzuzo ze-HDL zama-shrimp, ungayithokozela njengengxenye yokudla okuhlakaniphile kwenhliziyo.
Mhlawumbe kubaluleke kakhulu, thola ukuthi imfanzi yakho ivelaphi. Iningi lezimfanzi manje ezithengiswa e-United States zivela e-Asia. E-Asia, izindlela zokulima, kufaka phakathi ukusetshenziswa kwezibulala-zinambuzane kanye nemithi elwa namagciwane, kuye kwalimaza imvelo futhi kungaba nemiphumela emibi empilweni yabantu. Funda kabanzi ngemikhuba yokulima imfanzi e-Asia kuwebhusayithi yeNational Geographic, esihlokweni esathunyelwa ekuqaleni ngo-2004.
