Sayansi yamakono imatsimikizira kuti zakudya zochokera ku zomera zimakhala zachilengedwe kwa thupi lathu. Pali umboni wochuluka wosonyeza kuti zakudya zamasamba kapena zamasamba, zomwe zimakhala ndi mavitamini ndi mchere wofunikira, zimakhala ndi ubwino wambiri wathanzi.
"Kafukufuku amatsimikizira ubwino wa zakudya zopanda nyama," inatero Harvard Medical School. "Zakudya zochokera ku zomera tsopano sizikudziwika kuti ndizokwanira, koma monga njira yochepetsera chiopsezo cha matenda aakulu ambiri."
Sitikumvetsabe bwino kugwirizana pakati pa anthu amakono ndi makolo athu akutali kuti tiziona ngati zoona. Chisinthiko ndi chenicheni, chikhoza kuwonedwa paliponse m'chilengedwe, koma kugwirizana kwaumunthu ndi izo kuchokera ku malingaliro a sayansi akadali chinsinsi kwa ife.
Si chinsinsi kuti anthu safuna nyama kuti akhale ndi moyo. Ndipotu, kafukufuku akusonyeza kuti kudya zamasamba ndi njira yabwino kwambiri, osati kudya nyama kapena kutsatira zakudya za "paleo". Anthu ambiri zimawavuta kukhulupirira kuti zakudya zopanda nyama zimatha kupatsa thupi zonse zofunikira.
Zomwe zimadziwika kuti Caveman Diet kapena Stone Age Diet, zomwe zimachitika pazakudya za Paleo zimachokera ku lingaliro lakuti tiyenera kutsatira zakudya za makolo athu, omwe anakhalapo zaka 2,5 miliyoni zapitazo mu nthawi ya Paleolithic, yomwe inatha pafupifupi. Zaka 10 zapitazo. . Komabe, asayansi ndi ofufuza sanathe kudziwa ndendende zomwe achibale athu akutali adadya, koma olimbikitsa zakudya akupitiriza kuwalozera, kulungamitsa kudya nyama.
Zakudya zambiri zomwe anyani amadyedwa ndi zomera, osati zinyama, ndipo pali kafukufuku wosonyeza kuti izi zakhala zikuchitika kwa nthawi yaitali. Makolo athu mwachiwonekere sanali anthu odya mapanga, monga momwe amasonyezedwera kaŵirikaŵiri. Koma ngakhale atadya nyama, izi sizikusonyeza kuti ndife okhudzana ndi majini kuti tichite zomwezo.
Katherine Milton, yemwe ndi katswiri wa maphunziro a chikhalidwe cha anthu ku UC Berkeley, anati: “N’zovuta kunena za ‘zakudya zabwino kwambiri’ za anthu amakono chifukwa mitundu yathu imadya mosiyana. "Ngati wina adadyapo mafuta anyama ndi mapuloteni m'mbuyomu, izi sizikutsimikizira kuti anthu amakono ali ndi kusintha kwa majini ku zakudya zotere."
Kafukufuku wina adasanthula zakudya za a Neanderthals, omwe adasowa zaka 20 zapitazo. Poyamba ankaganiza kuti chakudya chawo chinali makamaka nyama, koma izi zinasintha pamene umboni wochuluka unapezeka kuti zakudya zawo zinaphatikizapo zomera zambiri. Asayansi aperekanso umboni wakuti zomerazi zinkagwiritsidwanso ntchito ngati mankhwala.
Nkhani yolemba Rob Dunn ya Scientific American yotchedwa "Pafupifupi Makolo Onse Aumunthu Anali Odyera Zamasamba" ikufotokoza bwino za vutoli kuchokera ku chisinthiko:
Kodi anyani ena amoyo amadya chiyani, omwe ali ndi matumbo ngati athu? Zakudya za pafupifupi anyani onse zimakhala ndi zipatso, mtedza, masamba, tizilombo, ndipo nthawi zina mbalame kapena abuluzi. Anyani ambiri amatha kudya zipatso zokoma, masamba, ndi nyama. Koma nyama ndi yosowa, ngati ilipo. N’zoona kuti nthawi zina anyani amapha ndi kudya ana a anyani, koma chiwerengero cha anyani odya nyama n’chochepa kwambiri. Ndipo anyani amadya nyama yoyamwitsa kwambiri kuposa nyani aliyense. Masiku ano, zakudya za anyani ndizochokera ku zomera osati zinyama. Zomera ndi zimene makolo athu akale ankadya. Atsatira zakudya za paleo kwa zaka zambiri, pamene matupi athu, ziwalo, makamaka matumbo asanduka.”
Wolembayo amatsutsanso kuti ziwalo zathu sizinapangidwe kuti zikhale nyama yophika, koma zidasinthika kuti zigaye nyama yaiwisi.
Zomwe kafukufuku akuwonetsa
- Pafupifupi zaka 4,4 miliyoni zapitazo, wachibale waumunthu ku Ethiopia, Ardipithecus, ankadya makamaka zipatso ndi zomera.
- Zaka zoposa 4 miliyoni zapitazo, kumbali ya Kenya ya Nyanja ya Turkana, zakudya za Annam australopithecine zinali ndi 90% ya masamba ndi zipatso, monga chimpanzi zamakono.
- Zaka 3,4 miliyoni zapitazo kumpoto chakum'mawa kwa Ethiopia, Afar Australopithecus inadya udzu wambiri, sedge ndi zomera zokometsera. Zimakhalabe chinsinsi chifukwa chake anayamba kudya udzu, chifukwa Annam australopithecine sanatero, ngakhale kuti ankakhala ku savannah.
Zaka zoposa 3 miliyoni zapitazo, wachibale wa Kenyanthropus adatengera zakudya zosiyanasiyana zomwe zimaphatikizapo mitengo ndi zitsamba.
- Pafupifupi zaka 2 miliyoni zapitazo kum'mwera kwa Africa, African Australopithecus ndi Paranthropus wamkulu ankadya tchire, udzu, sedge, ndipo mwina nyama zodyera.
- Zaka zosakwana 2 miliyoni zapitazo, anthu oyambirira ankadya udzu 35%, pamene Boyce's Paranthropus ankadya udzu 75%. Kenako mwamunayo anali ndi zakudya zosakaniza, kuphatikizapo nyama ndi tizilombo. Zikuoneka kuti nyengo yowuma idapangitsa Paranthropus kudalira kwambiri zitsamba.
- Pafupifupi zaka 1,5 miliyoni zapitazo, m'gawo la Turkana, munthu adawonjezera gawo lazakudya zamasamba mpaka 55%.
Homo sapiens mano anapeza anasonyeza kuti zaka 100 zapitazo anadya 000% ya mitengo ndi zitsamba ndi 50% nyama. Gawoli likufanana ndi zakudya za anthu aku North America amakono.
Zakudya zambiri za omwe adayenda Padziko lapansi kalekale tisanakhale odya zamasamba. Zinganenedwe motsimikiza kuti nyama momveka bwino siinayambe kudya zakudya za makolo athu. Ndiye n'chifukwa chiyani chakudya cha caveman chatchuka kwambiri? N’chifukwa chiyani anthu ambiri amakhulupirira kuti makolo athu ankadya nyama yambiri?
Masiku ano, anthu wamba ku North America amadya nyama yambiri tsiku lililonse, poganizira kuti ndi chizolowezi. Koma ngakhale makolo athu ankadya nyama, sankachita zimenezi tsiku lililonse. Pali umboni kuti nthawi yambiri anachita popanda chakudya konse. Monga pulofesa wa sayansi ya zamaganizo ku yunivesite ya Johns Hopkins Mark Matson ananenera, matupi a anthu asintha kuti akhale ndi moyo kwa nthawi yaitali popanda chakudya. Ichi ndichifukwa chake kusala kudya kwapakatikati ndi njira yabwino masiku ano yokhala ndi mapindu ambiri azaumoyo.
M’makampani amakono a nyama, mabiliyoni a nyama amaphedwa chaka chilichonse chifukwa cha chakudya. Amaukitsidwa kuti aphe, kubayidwa ndi mankhwala osiyanasiyana komanso kuzunzidwa. Nyama yosakhala yachilengedweyi yopangidwa pogwiritsa ntchito mankhwala ophera tizilombo komanso ma GMO ndi poizoni m'thupi la munthu. Makampani athu amakono a zakudya ali ndi zinthu zovulaza, mankhwala ndi zopangira zopangira zomwe zimakupangitsani kudzifunsa kuti: kodi tingatchule kuti "chakudya"? Tili ndi ulendo wautali kuti tidzakhalenso anthu athanzi.
