Kukho uphando oluninzi oluqinisekisa ukuba imfuzo yenye yezinto ezichaphazela kakhulu ukutyeba nokutyeba, nangaphezulu kokutya kunye nokuzilolonga. Nangona kunjalo, kuqhelekile ukugcinwa kwamafutha okongeziweyo ukuba kwenzeke ukuba sinemikhwa engafanelekanga yokutya kwaye sihlala phantsi.
Ngoku uphononongo lwakutsha nje ekhokelwa yiYunivesithi yaseTaiwan ityhila ukuba yeyiphi imithambo esebenzayo yokuthintela esi sifo sentliziyo, esachaphazela abantu abazizigidi ezingama-24 eSpain kuphela ngo-2016. Uphando luye lwathatha inxaxheba kwi-18.000 yabantu abaphakathi kwe-30 kunye ne-70 yeminyaka ubudala, ababeyiyo. ibandakanyiwe kwidathabheyisi yophando lwebhayoloji yaseTshayina.
Zeziphi ezona mithambo zilungileyo ukuze ungatyebi?
Uphando lwapapashwa kwiphephancwadi i-PLoS Genetics, apho kwaqinisekiswa ukuba ukuqhuba ukugijima (ukubaleka ngesantya sokubaleka) yayiyeyona ndlela ilungileyo yokulawula ukutyeba, ilandelwa zezinye izinto ezifana ukukhwela ibhayikhi entabeni, i ukuhamba ngeenyawo, la umngcelele weembaleki, ezinye iindlela ze baile kunye yoga.
Ngokutsho kwababhali bophononongo, le misebenzi yomzimba inceda ukunciphisa isalathisi sobunzima bomzimba kubantu abane-genetics eyenza ukuba bakhuluphele. Ngokusengqiqweni, ukuze ubone iingenelo zokwenza umthambo, kufuneka wenze njalo ziqheliseni ngokwesiqhelo, malunga nezihlandlo ezithathu ngeveki ubuncinane kangangemizuzu engama-30.
Uphononongo lukwafumanise ukuba eminye imisebenzi efana ukukhwela ibhayisekile, ukuzolula, okanye ukuqubha aziyithinteli imiphumo yemfuza ephembelela ukutyeba. «Ukuzolula kudla amandla amancinci kwaye ukuqubha kuvuselela umdla wokutya»U-Wan-Yu Lin, umbhali okhokelayo wesifundo, uchazela iSinc.
Ngaba sityebe kakhulu kwimfuza?
Ukuhlalutya oonobangela abachaphazela ukutyeba, Izifundo zangaphambili bezijonge kwi-BMI kuphela. "Ukuza kuthi ga ngoku, le nto inye iqwalaselwe kuba kulula ukuyibala, kodwa ukuba ubude nobunzima kuphela buqwalaselwa, ipesenti yamafutha akhoyo emzimbeni ayihoywa.wongeza uWan-Yu Lin.
Endaweni yoko, kwesi sifundo ezinye izinto ezine zokutyeba ziye zaqwalaselwa ezikwadityaniswe neengxaki zemetabolism. Oko kukuthi, imilinganiselo ithathwe kwisinqe kunye ne-hip circumference, i-BMI, ipesenti yamafutha omzimba kunye nomlinganiselo phakathi kwesinqe kunye ne-hip.
Kuyinyani ukuba ukutyeba sisifo esintsonkothileyo kwaye apho izinto ezininzi zinempembelelo, kodwa kolu phononongo kukho iingcebiso ezinikwe kolona hlobo lucetyiswayo lomsebenzi womzimba kubantu abachatshazelwe sesi sifo.
