Kodi mazira a nkhuku ndi chiyani?
Ndipotu dzira ndi dzira la nkhuku, mwachitsanzo, selo la nyama. N'chifukwa chiyani mazira amakhalapo m'chilengedwe? Kuti mbalame zikhale ndi ana. Kodi mwachibadwa munthu amadya mazira? Ichi ndi chinyengo chathunthu. Munthu sanali mwachibadwa wodya mazira, ngati mbala (wodya nyama) kapena kuyang’anira buluzi (wodya ana a mbalame) kapena chilombo china chilichonse chozizira kwambiri chimene chimadya miluza ya mbalame. Asayansi ndi zachilengedwe, kuphatikizapo Charles Darwin, amavomereza kuti anthu akale anali osadya zamasamba (anadya zipatso, ndiwo zamasamba ndi mtedza). M’mbiri yonse ya anthu, thupi lathu silinasinthe. Dr. Spencer Thompson ananenanso kuti: “Palibe katswiri wa zamoyo amene anganene kuti munthu ayenera kumangodya zakudya zamasamba.” Dokotala Sylvester Graham ikulemba kuti: “Mpangidwe woyerekezera wa thupi la munthu umatsimikizira kuti mwachibadwa munthu ali wodya udzu, kuchirikiza kukhalapo kwake ndi zipatso, njere ndi zomera za ufa.” Dokotala waku USA Michael Kleiper m’nkhani zake za thanzi, iye akupereka zotsatirazi: “Ngati mukuganiza kuti mwachibadwa munayenera kudya nyama, yesani kuthamangira kumunda, kulumpha pamsana pa ng’ombe ndi kuiluma. Mano athu kapena zikhadabo zathu sizingang’ambe n’komwe khungu lake.” Ngakhale kuti physiology yaumunthu (mapangidwe a thupi, matumbo, mano, ndi zina zotero) imasonyeza kuti thupi la munthu ndiloyenera kudya zakudya zamasamba, "odya zamasamba" ambiri omwe amalima kunyumba amadya mazira, omwe amawaganizira kuti amalimbikitsa zakudya zanu. ndi mapuloteni. Komabe, mazira, monga mitundu ina yonse ya nyama, amakhala ndi mphamvu zochepa kwambiri kuposa chakudya chamasamba - kuwonjezera apo, chamoyo chokhala ngati mluza chimatsekeredwa mu chipolopolo cha dzira, kutanthauza kuti chimakhala ndi mapuloteni opindika akufa ndi zinthu zomwezo. ndi mabakiteriya ovunda ngati nyama. Zakudya za mafia zafalitsa kwambiri nthano zokhuza phindu la mapuloteni mazirakoma ili ndi bodza losazindikira lomwe lilungamitsa bizinesi ya imfa. Mazira si chakudya chopatsa thanzi m’thupi la munthu, chifukwa “nyama yamadzimadzi” imeneyi imawola m’matumbo aatali kwambiri kuposa nyama. Kuphatikiza pa zonsezi, mazira ndi omwe amachititsa kuti m'matumbo apangidwe mpweya woipa wa ammonia. Kuphatikiza pa mabakiteriya omwe akubwera ndi poizoni, mazira amaphwanya zolemba zonse zamafuta a kolesterolini, ochulukirapo omwe amayambitsa matenda ambiri. AT mazira lili ndi zochuluka kuwirikiza kawiri mafutakuposa tchizi, ndipo katatu kuposa mafuta anyama. Cholesterol (steroid) ndi imodzi mwa mitundu yamafuta omwe amapezeka m'thupi lathu omwe thupi lathu limatha kudzipanga lokha, popanda kufunikira kwamafuta anyama. Cholesterol ndiyofunikira pakupanga mchere wa bile ndi mitundu ina ya mahomoni ogonana, komanso imakhudzidwa ndikugwira ntchito kwa ma cell. Munthu amene amaona thanzi lake ayenera kusiya kugwiritsa ntchito zogulitsa nyama (nyama, nsomba, mazira) kuteteza kuchuluka kwa cholesterol m'magazi. Ngakhale kuti mafuta amkaka amakhalanso ndi cholesterol, samaunjikana m'thupi la munthu, chifukwa mkaka uli lecithinkuwononga kwambiri cholesterol iyi. Zinthu zomwe zili m'mazira (makamaka mapuloteni) zitha kupezeka mosavuta komanso zopanda vuto kuchokera kuzinthu zamasamba. Ndicho chifukwa chake, m’zaka zaposachedwapa, chiŵerengero chowonjezereka cha anthu akuchoka ku zakudya za nyama (cholesterol, mafuta a saturated, ntchofu, ziro dietary fiber, etc.) ndipo akusintha n’kuyamba kudya zakudya zatsopano. zipatso и masamba.
