Isilumkiso: Ukutya ngokugqithisileyo kwe-vitamin B3 kuyingozi

I-Niacin, ekwaziwa ngokuba yi-vitamin B3, sisokha mzimba esibalulekileyo njengoko ilungu ngalinye lomzimba wethu lisidinga ukuze lisebenze kakuhle. Inokunyusa umngcipheko wesifo senhliziyo ngokubangela ukudumba kunye nokonakalisa imithambo yegazi.

Ingxelo eyapapashwa kwiphephancwadi iNature Medicine yatyhila ingozi eyayingaziwa ngaphambili yokutya izixa ezigqithisileyo zevithamin, efumaneka kukutya okuninzi, okuquka inyama, intlanzi, amandongomane, iisiriyeli eziqinisiweyo nesonka.

Ukukhangela izinto ezinobungozi ezingaziwayo kwisifo senhliziyo, ababhali bophando baqulunqa uhlalutyo lweesampuli zegazi ezivela kwizigulane ezingaphezu kwe-1162 XNUMX. Abaphandi babekhangela iimpawu eziqhelekileyo okanye iimpawu kwigazi lezigulane ezinokubonisa izinto ezintsha ezinobungozi.

Uphando lube nesiphumo sokufunyaniswa kwento kwezinye iisampulu zegazi ezenziwe kuphela xa kukho ubuninzi be-niacin.

Ukuhlaselwa yintliziyo kunye nokubetha

Oku kufunyenwe kukhokelela kwizifundo ezibini ezongezelelweyo zokuqinisekisa iziphumo, ezibandakanya idatha evela kubantu abadala be-3163 abanesifo senhliziyo okanye esikrokrelwayo.

Uphando olubini, olunye e-United States kunye nolunye lwaseYurophu, lubonise ukuba imveliso yokuchithwa kwe-niacin, i-4PY, iqikelele ingozi yabathathi-nxaxheba yokuhlaselwa yintliziyo, ukubetha kunye nokufa.

Inxalenye yokugqibela yophando ibandakanya iimvavanyo kwiigundane, kwaye xa iigundane zifakwe i-4PY, ukuvuvukala kwimithambo yegazi kwanda.

Kuyaphawuleka ukuba i-dose yemihla ngemihla ekhuthazwayo ye-niacin yamadoda i-16 milligrams ngosuku kunye nabasetyhini abangakhulelwanga i-14 milligrams ngosuku.

Abaphandi abazi ngoku ukuba bazoba phi umgca phakathi kweemali ezinempilo kunye nezingenampilo ze-niacin, nangona oku kunokumiselwa ngophando lwexesha elizayo.

Ziphephe izongezo ze-niacin

Ngaloo ndlela, utshilo uDkt. Stanley Hazen, uSihlalo weSebe le-Cardiovascular and Metabolic Sciences kwi-Lerner Research Institute yaseCleveland Clinic kunye noSihlalo weSebe le-Preventive Cardiology kwi-Heart, Vascular and Thoracic Institute. "Umntu oqhelekileyo kufuneka aziphephe izongezelelo ze-niacin ngoku sinesizathu sokukholelwa ukuba ukuthatha i-niacin eninzi kunokukhokelela kumngcipheko wesifo senhliziyo."

Ngenxalenye yakhe, uDkt Amanda Doran, uprofesa oncedisayo weyeza kwiSebe le-Cardiovascular Medicine kwi-Vanderbilt University Medical Centre, wathi izazinzulu ziye zaziwa amashumi eminyaka ukuba izinga le-cholesterol yomntu linokuba ngumqhubi omkhulu wesifo senhliziyo.

Wongeze ukuba naxa amanqanaba e-cholesterol ezigulana ehla, abanye bahlala besengozini enkulu yokuhlaselwa sisifo sentliziyo kunye nokubetha, wongeza ukuba ulingo luka-2017 lucebise ukuba umngcipheko owongezelelweyo unokunxulumana nokudumba kwemithambo yegazi.
