Gulu lina lapadziko lonse la asayansi linapeza kuti kutenga mapuloteni a nyama m'zakudya kumathandiza kuchepetsa moyo wa munthu, ndipo mapuloteni a masamba amawonjezera. Pepala la sayansi linasindikizidwa mu nyuzipepala ya sayansi yotchedwa "JAMA Internal Medicine".
Ofufuza ochokera ku yunivesite ya Harvard amaliza kufufuza kwakukulu komwe adafufuza meta-analysis ya deta yomwe inapezedwa panthawi ya maphunziro a zaumoyo a 131 akatswiri azachipatala ochokera ku America (342% ya akazi) "Nurse Health Study" (nthawi yotsatila ya 64,7 zaka) ndi Kuphunzira kwa Occupational kwa gulu la ogwira ntchito yazaumoyo (nthawi ya zaka 32). Kudya kwa michere kunayang'aniridwa kudzera m'mafunso atsatanetsatane.
Mapuloteni apakatikati anali 14% ya zopatsa mphamvu zonse zama protein anyama ndi 4% zama protein a zomera. Deta yonse yomwe inapezedwa idakonzedwa, kusinthidwa pazinthu zazikulu zomwe zimawopseza zomwe zimachitika pokhudzana ndi zakudya komanso moyo. Pamapeto pake, zotsatira zake zinapezedwa, malinga ndi zomwe kudya mapuloteni a nyama ndi chinthu chomwe chimawonjezera imfa, makamaka kuchokera ku matenda a mtima. Mapuloteni a masamba nawonso amaloledwa kuchepetsa kufa.
Kuchotsa atatu peresenti ya zopatsa mphamvu zonse ndi mapuloteni a masamba kuchokera ku mapuloteni a nyama opangidwa ndi nyama kunachepetsa imfa ndi 34%, kuchokera ku nyama yosakonzedwa ndi 12%, kuchokera mazira ndi 19%.
Zizindikiro zotere zimatsatiridwa kokha mwa anthu omwe adakumana ndi chimodzi mwazinthu zoopsa zomwe zimabwera chifukwa cha kukhalapo kwa zizolowezi zoipa, mwachitsanzo, kusuta fodya, kumwa mowa pafupipafupi, kulemera kwambiri komanso kusowa kwa masewera olimbitsa thupi. Ngati zinthuzi zinalibe, ndiye kuti mtundu wa mapuloteni omwe amadya sunakhudze nthawi ya moyo.
Kuchuluka kwa mapuloteni a masamba kumapezeka muzakudya monga: mtedza, nyemba ndi mbewu monga chimanga.
Kumbukirani kuti osati kale kwambiri, asayansi anachita kafukufuku wina wapadziko lonse, malinga ndi kudya nyama yofiira, makamaka nyama yowonongeka, kumakhudza kuwonjezeka kwa imfa kuchokera ku khansa, nthawi zambiri khansa ya m'matumbo. Pachifukwa ichi, nyama yokonzedwa idzaphatikizidwa mu Gulu 1 (ma carcinogens ena) a Mndandanda wa mankhwala omwe ali ndi carcinogens, ndi nyama yofiira - mu Gulu 2A (zotheka carcinogens).
