I-Vitamin B3, ekwabizwa ngokuba yi-niacin, yivithamin enyibilikayo emanzini eyenza imisebenzi eyahlukeneyo ebalulekileyo yomzimba emzimbeni, ngakumbi ngokutya. Ukutya okutyebileyo nge-niacin kubandakanya inyama, inkukhu, intlanzi, iimveliso zobisi, amandongomane, iinkozo ezipheleleyo kunye neembotyi.

Ngo-Okthobha 8, 2024, Abaphandi abavela kwiSibhedlele seSihlanu saseWuxi esidibene neYunivesithi yaseJiangnan bapapasha inqaku kwijenali yeBMC Public Health enesihloko esithi "Umbutho wokuthatha i-niacin kunye nokungasebenzi kakuhle kwemetabolism enxulumene.

Uphononongo lubonise ukulungelelaniswa kwe-U phakathi kwe-niacin intake kunye nokuxhaphaka kwe-MASLD, kwaye ukuxhaphaka kwe-MASLD kwehla ngokuthe ngcembe ngokunyuka kwe-niacin intake, kunye neyona nto iphantsi kakhulu kwi-23.6 mg ngosuku.

Kuphononongo, abaphandi bahlalutya umbutho phakathi kwe-niacin intake kunye nokuxhaphaka kwe-MASLD kubathathi-nxaxheba be-2,946 kwi-National Health and Nutrition Examination Survey (NHANES) cohort, i-avareji yobudala be-37 iminyaka, i-48 ipesenti yamadoda, kunye ne-1,385 kunye ne-MASLD, eyaqokelelwa ngodliwano-ndlebe lokutya.
Phakathi kwabo bonke abathathi-nxaxheba, i-avareji yemihla ngemihla ye-niacin yayiyi-22.6 mg, ngelixa abo abane-MASLD babenomlinganiselo ophantsi wokuthatha i-niacin, i-avareji ye-19.2 mg ngosuku.
Emva kokulungiswa kwezinto eziphazamisayo, uhlalutyo lufumene umbutho owenziwe ngu-U phakathi kwe-niacin intake kunye nomngcipheko we-MASLD, kunye nokuxhaphaka kwe-MASLD kuncipha ngokuthe ngcembe njengoko i-niacin intake yanda de yafikelela kwinqanaba le-23.6, emva koko ukuxhaphaka kwe-MASLD kwanda ngokuthe ngcembe.
Oku kuphakamisa ukuba ukunyuka kwe-niacin intake kunokunciphisa ukuxhaphaka kwe-MASLD, ephantsi kakhulu kwi-23.6 mg ngosuku.
