Bruce Springsteen amayimba kwambiri, "Baby, tinabadwira kuti tithamange," zachidziwikire, mu nyimbo yake yotchuka "Wobadwira Kuthamanga". Koma kodi mumadziwa kuti pali kuyenera kwina pamenepo? Ofufuza ochepa ku Baylor College of Medicine adafufuza izi-kapena makamaka, ngati zizoloŵezi zochita zolimbitsa thupi za amayi zomwe zidakhudza zomwe mwana wawo amachita pambuyo pake pamoyo wawo. Ndipo zotsatira zawo, zofalitsidwa mu The FASEB Journal, zikuwonetsa kuti anali kulondola! (Kodi The Boss amalakwitsa liti?)

Dr. Robert A. Waterland, pulofesa wothandizira wa ana, zakudya, ndi maselo ndi majini aumunthu ku USDA/ARS Children's Nutrition Research Center ku Baylor ndi Texas Children's Hospital, ndipo gulu lake linayamba kuyesa lingaliro ili pamwambali litamva za ochepa. amayi omwe adanena kuti pamene adachita masewera olimbitsa thupi nthawi zonse ali ndi pakati, mwana wawo amakhala wokangalika chifukwa cha izi. (Kodi Makolo Ndiomwe Ayenera Kuimba Mlandu pa Zochita Zanu Zolimbitsa Thupi?)


Kuti ayese theoramu, Waterland ndi gulu lake adapeza mbewa zazimayi 50 zomwe zimakonda kuthamanga (nanga, simukudziwa mbewa yemwe amakonda kuthamanga?) Ndikuzigawa m'magulu awiri-omwe amatha kupeza gudumu lokonda mbewa ali ndi pakati komanso gulu lina lomwe silinathe. Monga momwe amayembekezera amayi amunthu, maulendo omwe amayenda kapena kuyenda adachepa kutengera kutalika kwa nthawi yomwe anali ndi pakati. Zomwe ofufuzawo pamapeto pake adapeza ndikuti mbewa zomwe amayi amabadwa omwe amachita ali ndi pakati zinali pafupi 50% olimbikira kwambiri kuposa omwe anabadwa kwa amayi omwe sanachite masewera olimbitsa thupi. Kuphatikiza apo, zochita zawo zochulukirapo zidapitilira pakukula, ndikuwonetsa zotsatira zakuthupi kwakanthawi. (Onani Makhalidwe 5 Olakwika Omwe Mumalandira Kuchokera kwa Makolo Anu.)

"Ngakhale kuti anthu ambiri amaganiza kuti chizoloŵezi cha munthu chochita masewera olimbitsa thupi chimatsimikiziridwa ndi majini, zotsatira zathu zimasonyeza bwino kuti chilengedwe chingathandize kwambiri pakukula kwa mwana," adatero Waterland mu pepala.


Zabwino, koma kodi mungafanane ndi zotsatira zomwe tawona mu mbewa mwaumunthu wathu? Waterland adatiuza kuti inde, titha kutero. “Pa mbewa ndi anthu onse, kapangidwe ka ubongo kamene kamagwirizanitsa mfundo za m’maganizo kumadalira kuloŵetsa m’maganizo. Izi ndizowona kwa kotekisi wamakutu (dera laubongo lomwe limapanga zambiri kuchokera m'makutu) Lingaliro loti athandizire-mu kafukufukuyu, mwa mawonekedwe anyama-amathandizanso kuwongolera dongosolo laubongo lomwe limayang'anira momwe munthu amayendera zolimbitsa thupi ndizomveka, "akutero.

TL; DR? Ndizowoneka kuti zotsatira zitha kumasulira. Kuphatikiza apo, Waterland akuwona kufunikira kwa amayi apakati kuti azichita masewera olimbitsa thupi mokwanira ndikupanga phunziroli chifukwa china chosunthira, amayi. (Ndi nthano yonse kuti kuchita masewera olimbitsa thupi pamene uli ndi pakati ndi koipa kwa inu!)
