Boka renyika dzese revasayendisiti rakaona kuti kutora mapuroteni emhuka mukudya kunobatsira kuderedza tarisiro yehupenyu hwevanhu, uye mapuroteni emiriwo anowedzera. Pepa resainzi rakabudiswa mumagazini yesainzi inonzi "JAMA Internal Medicine".
Vatsvakurudzi vanobva kuHarvard University vakapedza chidzidzo chikuru umo vakaongorora meta-analysis yedata yakawanikwa panguva yezvidzidzo zvehutano zve131 vashandi vezvokurapa kubva kuAmerica (342% yevakadzi) "Nurse Health Study" (nguva yekutsvaga ye64,7 makore) uye Occupational kudzidza kweboka revashandi vehutano (nguva ye32 makore). Kudya kwekudya kwakaongororwa kuburikidza nemibvunzo yakadzama.
Iyo yepakati mapuroteni yekudya yaive 14% yemakoriori akazara eprotein yemhuka uye 4% yemapuroteni ezvirimwa. Yese data yakawanikwa yakagadziriswa, kugadzirisa iyo huru yengozi zvinhu zvinomuka zvine chekuita nekudya uye mararamiro. Pakupedzisira, zvigumisiro zvakawanikwa, maererano nekudyiwa kweprotein yemhuka chinhu chinowedzera kufa, kunyanya kubva kune zvirwere zvehutano hwemwoyo. Vegetable protein, zvakare, inobvumirwa kuderedza kufa.
Kutsiva zvikamu zvitatu kubva muzana zvemakoriyumu ese nemapuroteni emuriwo kubva kumapuroteni enyama yakagadziriswa kwakaderedza kufa ne34%, kubva munyama isina kubikwa ne12%, kubva mazai ne19%.
Zviratidzo zvakadaro zvakatevedzwa chete kune vanhu vakaonekwa kune imwe yezvipingamupinyi zvakakomba zvinokonzerwa nekuvapo kwetsika dzakaipa, semuenzaniso, kusvuta, kushandiswa nguva dzose kwezvinodhaka zvinodhaka, kuwandisa uremu uye kushaya basa rekuita muviri. Kana zvinhu izvi zvakanga zvisipo, saka rudzi rweprotein yakadyiwa rwakanga rusina simba pakutarisira hupenyu.
Huwandu hukuru hweprotein yemiriwo hunowanikwa mune zvekudya zvakaita se: nuts, legumes uye zviyo.
Yeuka kuti kwete kare kare, masayendisiti akaita imwe chidzidzo chepasi rose, maererano nekudya nyama tsvuku, kunyanya nyama yakagadziriswa, inokanganisa kuwedzera kwekufa kwekenza, kazhinji kenza yekoloni. Panyaya iyi, nyama yakagadziriswa ichabatanidzwa muBoka 1 (mamwe macarcinogens) eRunyorwa rwezvigadzirwa zvine carcinogens, uye nyama tsvuku - muBoka 2A (zvinogoneka carcinogens).
