Ubwino wa Omega-3 Fatty Acids pa Thanzi la Mtima
Thanzi la mtima ndi maziko ofunikira kwambiri pa moyo wabwino. Anthu ambiri amaganizira kwambiri kuchita masewera olimbitsa thupi komanso kupewa zakudya zokhala ndi shuga wambiri ndi mafuta okhuta, koma nthawi zambiri amanyalanyaza ntchito ya mafuta "abwino", omwe thupi limafunikira. Mtundu umodzi wa mafuta omwe amafufuzidwa kwambiri pa ubwino wa mtima ndi omega-3 fatty acids. Zakudya zimenezi zimadziwika kuti zimathandiza kusunga ntchito ya mitsempha yamagazi, kuwongolera kutupa, komanso kuthandizira kugunda kwa mtima kokhazikika. Nkhaniyi ikufotokoza za omega-3s, momwe imagwirira ntchito, komanso momwe mungadyere kuti mtima ukhale wathanzi.
Kodi mafuta a omega-3 acids ndi chiyani?
Omega-3s ndi gulu la ma polyunsaturated fatty acids ofunikira, zomwe zikutanthauza kuti thupi silingathe kuwapanga mokwanira ndipo liyenera kuwapeza kuchokera ku chakudya. Mitundu itatu yodziwika bwino ya omega-3s ndi iyi:
1. EPA (eicosapentaenoic acid): imapezeka kwambiri mu nsomba zamafuta ndi nsomba zam'madzi. EPA imagwira ntchito yowongolera kutupa ndi thanzi la mitsempha yamagazi.
2. DHA (docosahexaenoic acid): imagwiranso ntchito kwambiri m'nsomba, ndipo ndi yofunika kwambiri pa kapangidwe ka nembanemba ya maselo, kuphatikizapo maselo a mtima ndi mitsempha yamagazi.
3. ALA (alpha-linolenic acid): imapezeka m'zomera monga mbewu za fulakesi, mbewu za chia, mtedza, ndi mafuta a canola. ALA ikhoza kusinthidwa kukhala EPA ndi DHA, koma kuchuluka kwa kusintha kwa mafuta ndi kochepa mwa anthu ambiri.
Ngakhale kuti zonse zitatuzi n’zothandiza, kafukufuku wamphamvu kwambiri wokhudza thanzi la mtima nthawi zambiri amakhudzana ndi kumwa EPA ndi DHA kuchokera ku zinthu za m’nyanja.
Chifukwa chiyani omega-3 ndi yofunika kwambiri pamtima?
Matenda a mtima ndi mitsempha yamagazi akadali chifukwa chachikulu cha matenda m'maiko ambiri. Zinthu zomwe zimayambitsa matendawa ndi monga kuthamanga kwa magazi , kusalinganika kwa cholesterol, kutupa kosatha, matenda a shuga, kusuta fodya, ndi moyo wongokhala. Ma Omega-3 amagwira ntchito m'njira zosiyanasiyana nthawi imodzi—osati ngati “mankhwala amodzi,” koma ngati gawo la zakudya zabwino komanso moyo wothandiza mtima.
Nazi zina mwazabwino zofunika kwambiri za omega-3 pa thanzi la mtima.
1. Zimathandiza kuchepetsa kuchuluka kwa triglycerides
Chimodzi mwa zabwino zomwe zatsimikiziridwa bwino za omega-3s ndi kuthekera kwawo kuchepetsa triglycerides—mtundu wa mafuta m'magazi omwe, akakhala okwera, amagwirizanitsidwa ndi chiopsezo chowonjezeka cha matenda amtima. Omega-3s, makamaka EPA ndi DHA, amatha kuchepetsa kupanga triglyceride m'chiwindi ndikuwonjezera kutuluka kwawo m'magazi.
Kwa anthu ena omwe ali ndi triglycerides yambiri, kudya omega-3s mu mlingo winawake (nthawi zambiri kudzera mu zowonjezera zomwe dokotala amalangiza) kungachepetse kwambiri triglycerides. Komabe, ndikofunikira kumvetsetsa kuti kuchepetsa triglycerides yambiri kumafuna njira yokwanira: kuchepetsa shuga wosavuta, kuchepetsa mowa, kuchepetsa kulemera, komanso kuwonjezera masewera olimbitsa thupi.
2. Imathandiza kuthamanga kwa magazi bwino
Ma Omega-3 angathandize kuchepetsa kuthamanga kwa magazi pang'ono mpaka pang'ono, makamaka kwa anthu omwe ali ndi kuthamanga kwa magazi kapena kuthamanga kwa magazi kozungulira. Njirayi imaganiziridwa kuti ikugwirizana ndi ntchito yabwino ya endothelial (mkati mwa mitsempha yamagazi), kusinthasintha kwa mitsempha yamagazi, komanso mphamvu zotsutsana ndi kutupa.
Ngakhale kuti omega-3s sizingalowe m'malo mwa mankhwala ochepetsa kuthamanga kwa magazi ngati pakufunika, zitha kukhala zina zomwe zimathandiza anthu omwe ali ndi kuthamanga kwa magazi, makamaka akaphatikizidwa ndi zakudya zoyenera monga zakudya za ku Mediterranean kapena DASH.
3. Amachepetsa kutupa komwe kumayambitsa matenda a atherosclerosis
Matenda a atherosclerosis (kuwunjikana kwa ma plaque pa makoma a mitsempha yamagazi) si "kuwunjikana kwa mafuta" kokha, koma ndi njira yovuta yokhudza kutupa kosatha. Ma Omega-3 ali ndi mphamvu zotsutsana ndi kutupa kudzera mu kupanga zinthu zinazake (monga ma resolvins ndi protectins) zomwe zimathandiza kuwongolera kuyankha kwa kutupa.
Ndi kutupa kolamuliridwa bwino, kukhazikika kwa plaque kumatha kusintha. Plaque yokhazikika siingathe kuphulika ndi kuyambitsa magazi kuundana omwe angayambitse matenda a mtima kapena sitiroko.
4. Zimathandiza kuti mtima ukhale wokhazikika
Kusokonezeka kwa kugunda kwa mtima (arrhythmias) kumatha kuyambira kofatsa mpaka koopsa. Ma Omega-3 akuganiziridwa kuti amathandizira kukhazikika kwa magetsi kwa maselo a mtima pokhudza ma cell nembanemba ndi njira zina za ion. Kafukufuku wambiri wasonyeza kuti kudya nsomba nthawi zonse kumagwirizanitsidwa ndi chiopsezo chocheperako cha imfa yadzidzidzi chifukwa cha mavuto a kugunda kwa mtima.
Komabe, zotsatira za omega-3 pa matenda a arrhythmia sizifanana pa mitundu yonse ya anthu komanso matenda ena. Chifukwa chake, kwa odwala omwe ali ndi mbiri ya arrhythmias kapena omwe akumwa mankhwala ena, kufunsa dokotala ndikofunikira kwambiri musanagwiritse ntchito mankhwala owonjezera a mlingo waukulu.
5. Kumalimbitsa thanzi la mitsempha yamagazi
Endothelium yathanzi imathandiza mitsempha yamagazi kukula ndi kufupika bwino, kupewa kuuma kwambiri kwa magazi, komanso kuwongolera kuyenda kwa magazi. Omega-3s imathandizira ntchito ya endothelial ndipo imatha kuwonjezera kufalikira kwa magazi (kukulirakulira kwa mitsempha yamagazi). Kuphatikiza apo, omega-3s imatha kusintha mawonekedwe a ma platelet, ndikuletsa kuuma kwambiri kwa magazi—ngakhale kuti izi nthawi zambiri zimakhala zochepa pazakudya.
Kuti mtima ukhale wathanzi, mitsempha yamagazi yogwira ntchito bwino yomwe siingathe kugwira ntchito bwino mu endothelium ndi phindu la nthawi yayitali.
6. Kuthekera kokonzanso mawonekedwe onse a lipid
Pokambirana za mafuta m'magazi, anthu nthawi zambiri amaganizira kwambiri za cholesterol ya LDL ("yoyipa") ndi HDL ("yabwino"). Ma Omega-3 si mankhwala ochepetsa LDL monga ma statins, koma amatha kukhala ndi zotsatira zabwino pa ma lipid profiles, makamaka pochepetsa triglycerides. Mwa anthu ena, DHA imatha kukweza pang'ono LDL, ngakhale izi nthawi zambiri zimayenderana ndi kusintha kwa kukula kwa tinthu ta LDL, zomwe zimapangitsa kuti zikhale zazikulu komanso zosayambitsa atherogenic. Ili ndi gawo lovuta, kotero kutanthauzira kumafuna kuyang'ana chithunzi chonse cha chiopsezo, osati nambala imodzi yokha.
Magwero abwino kwambiri a omega-3
Kuti mupeze phindu la mtima , yang'anani pa zakudya zonse. Zosankha zina zokhala ndi EPA ndi DHA:
- Salimoni
– Ma sadini
- Nsomba ya makerele
- Anchovy
– Tuna (samalani kuchuluka kwa chakudya ndi komwe chimachokera)
Magwero abwino a zomera (ALA) ndi awa:
- Mbewu za Chia
- Mafuta a fulakesi ndi fulakesi
- Canary
– Edamame/soya
- Mafuta a canola
Kuphatikiza nsomba ndi zomera kungakhale njira yabwino, makamaka kwa iwo omwe akufuna kuchepetsa kudya nyama yofiira kapena kutsatira zakudya zinazake.
Kodi mungaigwiritse ntchito bwanji bwino?
Kawirikawiri, malangizo ambiri okhudzana ndi zakudya amalimbikitsa kudya nsomba zonenepa kawiri pa sabata ngati gawo la zakudya zabwino. Njira yokonzekera imafunikanso: nsomba yokazinga, yophikidwa ndi nthunzi, kapena yokazinga mu mafuta ochepa ndi yabwino kuposa yokazinga kapena yoperekedwa ndi msuzi wokhala ndi mchere wambiri komanso mafuta okhuta.
Ngati mukuvutika kukwaniritsa zakudya zomwe mumadya, zakudya zowonjezera za omega-3 zingakhale zoyenera kuziganizira, makamaka pa matenda monga triglycerides yambiri. Komabe, kusankha mankhwala kuyenera kuganizira kuchuluka kwa EPA/DHA pa kapisozi iliyonse, mtundu wa kuyeretsa thupi, komanso momwe mankhwala ochepetsa magazi angagwirizanire ndi mankhwala ochepetsa magazi. Kufunsana ndi katswiri wa zaumoyo kumalimbikitsidwa musanayambe kumwa mankhwala owonjezera a mlingo waukulu.
Ndani ayenera kusamala?
Omega-3 yochokera ku chakudya nthawi zambiri imakhala yotetezeka kwa anthu ambiri. Komabe, pali zinthu zina zomwe zimafunika kusamalidwa:
– Kugwiritsa ntchito mankhwala oletsa magazi kuundana/oletsa magazi kuundana: kuchuluka kwa omega-3 kungapangitse kuti anthu ena azitaya magazi ambiri.
– Ziwengo za nsomba/za m'nyanja: muyenera kusankha zomera kapena zowonjezera zakudya zotetezeka malinga ndi malangizo a dokotala.
– Mimba: DHA ndi yofunika, koma muyenera kusamala ndi nsomba zomwe zili ndi mercury yochepa.
Kuphatikiza apo, ndikofunikira kusankha nsomba kuchokera ku malo abwino ndikusamala za mavuto omwe ali ndi poizoni (monga mercury mu nsomba zina zazikulu).
Kutseka
Mafuta a Omega-3 ndi michere yofunika kwambiri yomwe imapereka maubwino angapo abwino a mtima, kuyambira kuchepetsa triglycerides ndikuthandizira kuthamanga kwa magazi, kuchepetsa kutupa, mpaka kusunga ntchito ya mitsempha yamagazi komanso kugunda kwa mtima kokhazikika. Ngakhale kuti omega-3 si "njira yofulumira," kuwaphatikiza muzakudya zopatsa thanzi - makamaka mwa kudya nsomba zonenepa nthawi zonse - kungakhale njira yosavuta koma yothandiza kwambiri yopezera thanzi la mtima kwa nthawi yayitali.
Ngati muli ndi matenda enaake monga triglycerides yambiri, kuthamanga kwa magazi, kapena mukumwa mankhwala ochepetsa magazi, ganizirani kufunsa dokotala kapena katswiri wa zakudya kuti mudziwe njira yoyenera komanso yotetezeka yogwiritsira ntchito omega-3. Mukachita njira yoyenera, omega-3s ikhoza kukhala imodzi mwa njira zabwino kwambiri zothandizira mtima wanu kukhala wathanzi.
