Chikafu chepamusoro cheprotein muzera repakati chinowedzera njodzi yehupenyu uye hutano ne74%, maererano nemhedzisiro yeongororo yazvino pamusoro penyaya iyi, yakaitwa nemasayendisiti kubva kuYunivhesiti yeSouthern California (USA).
Kugara kudyiwa kwechikafu chine macalorie akawanda - senyama nechizi - kunowedzera zvakanyanya njodzi yekufa negomarara nezvimwe zvirwere, saka kudyiwa kweprotein yemhuka kunofanirwa kunzi kunokuvadza, vanodaro. Ichi ndicho chidzidzo chekutanga munhoroondo yemishonga kuratidza hukama hwakananga pakati pekudya kwakanyanya muprotein yemhuka uye kuwedzera kukuru kwekufa kubva kune dzakawanda zvirwere zvakakomba, kusanganisira kenza uye chirwere cheshuga. Muchokwadi, mhedzisiro yechidzidzo ichi inotaura mukufarira veganism uye kuverenga, "low-calorie" vegetarianism.
Masayendisiti eAmerica akawana kuti kushandiswa kwezvigadzirwa zvemhuka zvine mapuroteni akawanda: kusanganisira marudzi akasiyana-siyana enyama, pamwe chete nechizi nemukaka, kwete chete kuwedzera ngozi yekufa nekenza ne4 nguva, asiwo kunowedzera mikana yezvimwe zvirwere zvakakomba. 74%, uye kakawanda inowedzera kufa kubva kuchirwere cheshuga. Masayendisiti akaburitsa mhedziso yesainzi inonakidza mupepanhau resainzi Cellular Metabolism munaKurume 4.
Nekuda kweongororo yakatora makore anoda kusvika 20, vanachiremba vekuAmerica vakawana kuti kudyiwa zvine mapuroteni zvine mwero kunoruramiswa chete kana wava nemakore anopfuura 65, nepo mapuroteni achifanira kuganhurirwa muzera repakati. Izvo zvinokuvadza zvinokonzerwa ne-high-calorie foods pamuviri, saka, zvinenge zvakaenzana nekukuvadza kunokonzerwa nekusvuta.
Kunyange zvazvo chikafu chakakurumbira chePaleo neAtkins chichikurudzira vanhu kudya nyama yakawanda, chokwadi ndechokuti kudya nyama kwakaipa, vatsvakurudzi veAmerica vanoti, uye kunyange cheese nemukaka zvinodyiwa zvakanyanya muhuwandu hushoma.
Mumwe wevanyori vanyori vekudzidza, Dr., Purofesa weGerontology Walter Longo, akati: "Pane pfungwa isina kururama yokuti kudya kunozviratidza - nokuti isu tose tinodya chimwe chinhu. Asi mubvunzo hausi nzira yekutambanudza mazuva matatu, mubvunzo ndewokuti - pane rudzi rwezvokudya zvaunogona kurarama kusvika kumakore zana?
Ichi chidzidzo chakasiyanawo pakuti chaifunga kuti munhu mukuru maererano nemishonga yezvokudya kwete senguva imwe chete, asi sehuwandu hwemapoka ezera akasiyana, rimwe nerimwe rine kudya kwaro.
Masayendisiti akawana kuti mapuroteni anodyiwa muzera repakati anowedzera huwandu hwehomoni IGF-1 - kukura kwehomoni - asiwo inobatsira mukukura kwekenza. Zvisinei, pazera remakore makumi matanhatu nemashanu, chiyero chehomoni iyi chinodonha zvakanyanya, uye zvinokwanisika kudya zvokudya zvine mapuroteni akawanda, zvakachengeteka uye nehutano hwehutano. Muchokwadi, inotenderedza musoro wayo isati yavapo mazano ekuti vanhu vezera repakati vanofanira kudya sei uye kuti vanhu vakura vanofanira kudya sei.
Chinonyanya kukosha kune vegans uye vegetarians, chidzidzo chimwechete chakawanawo kuti mapuroteni anodyarwa (akadai seanotorwa kubva kumarimu) haawedzere njodzi yechirwere chakakomba, kusiyana neprotein-based protein. Yakawanikwa zvakare kuti huwandu hwemakhahydrates nemafuta anopedzwa, kusiyana neprotein yemhuka, haina kukanganisa kune hutano uye haideredzi hupenyu hwehupenyu.
"Vazhinji veAmerica vari kudya mapuroteni akapetwa kaviri sezvavanofanira - uye zvichida mhinduro yakanakisisa yedambudziko iri ndeyokuderedza kudya kweprotein kazhinji, uye kunyanya mapuroteni emhuka," akadaro Dr. Longo. "Asi haufanirwe kuenda kune imwe yakanyanyisa uye kurega mapuroteni zvachose, kuti ugone kukurumidza kushaya chikafu."
Akakurudzira kushandisa mapuroteni kubva kumiti yemiti, kusanganisira nyemba. Mukuita, Longo nevamwe vake vanokurudzira chiyero chekuverenga chiri nyore: muvhareji yezera, unoda kudya 0,8 g yeprotein yemiriwo pa kilogram yehuremu hwemuviri; kumunhu wepakati, iyi inenge 40-50 g yeprotein (3-4 servings yevegan food).
Iwe unogonawo kufunga zvakasiyana: kana iwe ukasawana kudarika 10% yemakoriyori ako ezuva nezuva kubva kumapuroteni, izvi zvakajairika, kana zvisina kudaro iwe uri pangozi yezvirwere zvakakomba. Panguva imwecheteyo, masayendisiti akaongorora kudyiwa kweanopfuura makumi maviri muzana emakoriyumu kubva kumapuroteni kune njodzi zvakanyanya.
Vesainzi vakaedzawo pambeva dzemurabhoritari, zvichiita kuti dzive nemamiriro ezvinhu ekuitika kwegomarara (mbeva dzisina kunaka! Vakafira sainzi - Vegetarian). Zvichienderana nemhedzisiro yekuyedza kwemwedzi miviri, masayendisiti akataura kuti mbeva dzaive pakudya kwakaderera-protein, kureva dziya dzakadyiswa gumi kubva muzana kana zvishoma zvemakori adzo kubva kumapuroteni angangoita hafu yemukana wekuita kenza kana kuve ne10% mamota madiki. kupfuura vamwe vavo vakadyisa chikafu chepakati nepamusoro cheprotein.
"Tinenge tose zvedu tinokura masero ekenza kana pre-kenza pane imwe nguva muupenyu hwedu," akadaro Dr. Longo. "Mubvunzo chete ndewekuti chii chinotevera kwavari!" Vari kukura here? Chimwe chezvinhu zvakakosha zvinotaridza pano chichava huwandu hweprotein yaunoshandisa.
