Kutheni kunzima ukuba unciphise umzimba ngaphezu kweminyaka engama-30 eyadlulayo?

Asinto kunzima ukuthelekelela ukuba ubunzima umzimba kwandisa ukuba udle ngaphezu umzimba kutsha nge eyahlukahlukeneyo. Nangona lo mthetho ibeyinto saziwe, kukho ezinye izinto ukuba ibe nefuthe elibi ubunzima bakho. Ngokutsho sifundo, ogama iziphumo zapapashwa kwijenali Research Ukutyeba kunye Practice lwezonyango, le minyaka ilishumi ohlala kuyo kwakhona kubalulekile ukuba iinketho zakho.

experiment Inkqubela

Phakathi nokuhlola, izazinzulu ezi iiseti ezimbini eziphambili ze data zaxilongwa: idayethi umsebenzi zenyama avareji eMerika iminyaka engamashumi amathathu. Emva koko, la manani ngenxa ezibekwe kwaye kuthelekiswa. nxaxheba sifundo akhethiweyo kunini na. 14.419 AmaMelika ibhengeze umsebenzi ebonakalayo kwisithuba ukususela 1988 ukuya 2006. Enye 36 400 kubonisiwe abadla kwisithuba ukususela 1971 ukuya ku 2008. Ngenxa yoko, izazinzulu banethuba umzimba mass index izibalo aqhube, ngokuxhomekeke osidingayo zokungenisa umsebenzi ngokwasemzimbeni kwiminyaka ezahlukeneyo.

iziphumo

Ekugqibeleni kwathi ukuba abantu ababini abaneminyaka efanayo, pahla imali efanayo lweekhalori, iivithamini, macronutrients, yaye ngubani sendleleni inani elifanayo iiyure ngeveki, kufuneka umahluko BMI ngokutsho kunyaka kwikhalenda. Umzekelo, ubunzima bomzimba isalathisi womntu, abahlala 1988, i-avareji kwaba engaphantsi nge- 2.3 amanqaku kuthelekiswa kumfo 2006. Xa jikelele, avareji amaMelika 5-10 ekhulwini namhlanje inzima ngaphezu wayeneminyaka 20-30 eyadlulayo. Kwaye oku ngenxa yokuba kufuneka utye kakhulu kwaye ushukume ngaphantsi. Kukho ezinye izinto musa ukuvumela ukuba unciphise umzimba ngokukhawuleza abantu mihla.

Kutheni kunzima ukuba ukuncipha?

umama kunye notata yethu abazange ukuhlangabezana iingxaki ezinjalo. Bubuyiselwe ubunzima esiqhelweni, kuba kubo, kwanele nje ukunciphisa kilojoules, musani ukudla ebusuku, okanye usebenzise kwiikhilomitha ezongezelelweyo ezimbalwa ngeveki. Ukuze kuthi, ukuba umzimba ukuya meko efanayo, kufuneka uzame kangangoko yam. Kodwa uthe enye ababhali kolu phando, uNjingalwazi Dzhennifer Kuk: "Ukuba lo mzuzu wawela uphawu kunyaka-40, kuya kufuneka ukuba nokutya ngaphantsi, kunye nokubila kwi gym ngaphezu kweminyaka engamashumi amane abantu ababehlala 1971 ' .

izinto ezingenzeka: iziyobisi

Ukuba achaze isenzeko lwangoku, uGqr Cook ubeke phambili izizathu ezithathu kunokwenzeka, owokuqala apho kukwandisa ukusetyenziswa kweziyobisi. kwimboni yezemithi ngonyaka ngamnye ukusebenza ngakumbi esebenzayo. abantu Modern beqhubeka waguqukela iipilisi xa ukuphatha ukudakumba, isifo sentliziyo, kwaye nkqu yintloko. Umzekelo, i yeQela, "Prozac" kuqala yafumaneka ngo-1988. Ukususela ngoko, ukusetyenziswa kweli chiza nyaka ngamnye kwanda. Weight bazuze inokuba nefuthe ecaleni iziyobisi emane zinqanda serotonin reuptake. Iinkcukacha-manani zibonisa la manani. Ngenxa yoko, 25 ekhulwini izigulane ezithatha lakhula baphawula ukwanda ubunzima bomzimba ngomyinge wesi-4.5 eekhilogram.

microbiome kwabantu Changed

microbiome Human - intsholongwane ukuba ahlale umzimba. Abanye babo bahlala emathunjini, kwaye ezinye iindidi iintsholongwane wamathumbu kunokusenza mngcipheko mkhulu ukutyeba kunye nokutyeba. Ukutya uyakwazi ukutshintsha microbiome - inyama. Kwaye akukho nto ayimangalisi, kuba abavelisi zixheshiswa iinkukhu kunye nokukhula neenkomo hormone nemithi. Kodwa, ukusetyenziswa inyama kumazwe aphuhlileyo landa nge-5 ekhulwini xa kuthelekiswa ukuya ku-1970. Ezinye izinto kulwabiwo ahlasela bacterium ama, ingabizwa sweeteners ngumntu, kunye zinambuzane eziqulathwe iziqhamo kunye nemifuno.

Imichiza nokubopha ukutya

Ngokutsho Dzhennifer Kuk, zonke zinambuzane neekhemikhali abafunyanwa ukupakisha ukutya mihla, ekwaziyo ukutshintsha iihomoni. Oku, wazisa uhlengahlengiso kwindlela imizimba yethu namafutha. Imichiza ngaphezulu engena emzimbeni wethu, le lula ukuba senziwa similise umzimba. Koda kube nini na ukuba amanzi okusela yeebhotile zeplastiki, ukutya nesoseji okanye uthathe iipilisi? Kubonakala ukuba akusekho mfuneko ukukhalaza impumelelo ophantsi bakudle ukusebenzisa. Ihlabathi esiphila kudala ibe nye, siya kuya kufuneka ukuba kusetyenziswa izinto ezintsha.
