Caffeine ndi mankhwala omwe amapezeka m'mitengo, zipatso, ndi masamba a zomera zina. Kafeine amapezeka kawirikawiri monga khofi kapena tiyi, ndipo ena akuganiza kuti zakumwa izi ndizo zakudya zomwe zimadya kwambiri padziko lapansi.
Chifukwa caffeine imakhala yowonjezereka m'mitundu yonse ya anthu, tafufuza zambiri kuti tipeze zotsatira za thanzi la caffeine.
Ubale pakati pa caffeine ndi matenda a mtima, komanso caffeine-kuthamanga kwa magazi, akhala akugwira ntchito mwakhama.
Kodi Zopatsa Mphamvu Ndi Ziti?
Zolimbikitsa, mwa tanthawuzo, yonjezerani ntchito ya pakatikati ya mitsempha, chifukwa chake amakupangitsani kukhala ogalamuka, okhudzidwa, ndi ochenjera. Komabe, ntchitoyi yowonjezera ikhoza kuyambitsa magazi a chotengera chotengera magazi, chomwe chingapangitse kukakamizidwa kwa magazi ndikusintha magazi kumtima. Ndipotu, zoopsa zambiri zomwe zimachititsa kuti tizilombo toyambitsa matenda monga cocaine ndi methamphetamine ndi zotsatira za ntchito yawo pamitsempha ya magazi ndi mtima.
Chifukwa caffeine ndi yokondweretsa, pali chifukwa chabwino chokayikira kuti khofi ndi kuthamanga kwa magazi zingakhale zogwirizana. Komabe, caffeine imakhala yofewa kwambiri ndipo imakhala ndi moyo wautali m'thupi. Caffeine imadzipangitsanso chifukwa chakuti imagwira impso kuti iwonjezere mlingo wake wokha.
Caffeine, Kuthamanga kwa Magazi, ndi Mtima
Umboni wabwereza mobwerezabwereza kuti kumwa mowa wa khofi sikungapangitse chiopsezo cha kuthamanga kwa magazi, matenda a mtima, kapena matenda a mtima . Kafukufuku wina wodziwika kwambiri anafufuza amayi opitirira 85,000 pazaka khumi ndipo anapeza kuti palibe vuto lililonse la matendawa, ngakhale amayi omwe amamwa makapu oposa asanu ndi limodzi patsiku.
Komiti Yachiwiri ya National Hypertension imanena mosapita m'mbali kuti palibe umboni womwe umagwirizanitsa khofi / tiyi ndi kuthamanga kwa magazi.
Ngakhale kuti kafukufuku wina waposachedwapa awonetsa mgwirizano wofooka pakati pa caffeine ndi kukwera kwa kuthamanga kwa magazi, zotsatira zake ndi zovuta ndipo zimangoganizira zotsatira zochepa chabe.
Mwachitsanzo, kafukufuku wina wotchulidwa kwambiri anapeza kuti kuthamanga kwa magazi kunayambira pang'onopang'ono atangomwa chakumwa cha khofi komanso kuti kuthamanga kwa magazi kumatchulidwa kwambiri kwa anthu omwe ali ndi mphamvu yambiri ya magazi. Komabe, kukwera uku sikunali kwakukulu ndipo kunangotsala kanthawi kochepa. Phunziroli linasonyezanso kuti pafupifupi 15 peresenti ya anthu omwe ali ndi kuthamanga kwambiri kwa magazi, kumwa mowa wamwasaini kumachepetsa kuchepa kwa magazi.
Maphunziro awiri ofunikira omwe anafalitsidwa mu 2007 analimbikitsanso bungwe la umboni lomwe likupezekapo posonyeza kuti:
- Kusintha kwa magazi kwa caffeine kunasintha ndi kochepa komanso kosakhalitsa
- Caffeine sichimathandiza kuti mitsempha ya magazi iwonongeke ndi matenda a mtima komanso matenda a mtima
Kufufuza kochititsa chidwi kunasonyeza kuti ubale wa khansa wa caffeine ukhoza kukhala wophweka kuposa momwe umayenera.
Kafukufukuyu adafufuzira momwe kuchuluka kwa khofi kumakhudzidwa ndi chiopsezo cha kuthamanga kwa magazi. Ngakhale zotsatira zake zasonyeza kuti chiopsezo cha kuthamanga kwa magazi ndi chochepa kwambiri kwa iwo omwe samamwa khofi, zinkasonyezeranso kuti omwe amamwa khofi ambiri amakhala ndi chiwonongeko chomwecho. Posayembekezereka, anthu omwe amamwa khofi pang'ono (1-3 makapu pa tsiku) amawoneka kuti ali ndi chiopsezo chachikulu. Zimakhulupirira kuti m'kupita kwa nthawi, thupi limapirira zowawa za caffeine.
Ubwino wa Zaumoyo
Coffee ndi tiyi zitha kukhala ndi ubwino wambiri wathanzi. Ngakhale tiyi wobiriwira unali wotchuka kwa zaka zingapo monga mavitamini abwino ndi ma antioxidants, kufufuza kwatsopano kwasonyeza kuti zakumwa zakuda monga tiyi wakuda ndi khofi zingakhale zabwino kwa inu.
Zakumwa zamdimazi ndizowonjezera mankhwala omwe amatchedwa polyphenols, omwe angateteze ku matenda a mtima komanso mitundu yambiri ya khansa. Kafukufuku waposachedwapa, akhala akuwonetsa kuchepa kwa chiwindi cha chiwindi mwa amuna omwe amamwa khofi.
Coffee ndi tiyi polyphenols zasonyezedwa kuti zichepetse mlingo wa mapuloletsedwe omwe ali mkati mwazi, zomwe zingathandize kupewa magazi omwe angayambe kupweteka. Polyphenols awonetsanso kuti kuchepetsa thupi la C-reactive puloteni (CRP), chinthu chofunika pa kutupa. Kuchuluka kwa CRP kwawonetsedwa kale kuti kuchepetsa chiopsezo cha mtima, matenda a mtima, ndi matenda ena a impso.
Ngakhale khofi ndi tiyi zili ndi polyphenols ambiri, mitundu ina ya polyphenols imapezeka mu zakudya zosiyanasiyana. Ma polyphenols onse awonetsedwa kuti ali ndi ubwino wathanzi, koma opindulitsa kwambiri kupatula iwo omwe ali mu khofi ndi tiyi akuwoneka kuti:
- Mphesa polyphenols
- Apple polyphenols
- Chokoleti polyphenols (chokoleti chakuda ndi mafuta oposa 80 peresenti)
Ngakhale umboni wa sayansi uyenera kukutsimikizirani ngati muli khofi kapena wothira tiyi, sizikutanthauza kuti muyenera kuyamba chifukwa cha phindu la thanzi. Zakudya zabwino zomwe zimakhala ndi zipatso ndi ndiwo zamasamba zimakhalanso ndizimene zimagwiritsidwa ntchito popangidwa ndi polyphenols ndi mankhwala a polyphenol.
