Kusabereka ndiko kuzindikira kwa 10-15 peresenti ya maanja omwe akufuna kutenga pakati, ndipo pafupifupi theka la vuto ndi mwamuna. Kafukufuku waposachedwa wa Harvard adapeza kuti kungowonjezera 5 peresenti yamafuta odzaza mafuta kunalumikizidwa ndi kuchepa kwa 38 peresenti ya umuna.
Koma chifukwa chiyani? Izi zitha kukhala chifukwa cha kusokonekera kwa endocrine chifukwa cha zoipitsa zamafakitale zomwe zimawunjikana m'mafuta anyama, makamaka mafuta a nsomba, ndipo zimawononga chonde pamwamuna, osati potengera kuchuluka kwa umuna, komanso momwe zimagwirira ntchito. .
Kafukufuku waposachedwapa anapeza kuti mwayi wopeza bwino ndi kuyika dzira lokhala ndi umuna umachepetsedwa mwa odwala omwe adanena kuti amadya nyama pafupipafupi. Ofufuza akukhulupirira kuti zoipitsa m'mafakitale ndi ma steroids omwe amapezeka m'zanyama ndizomwe zimayambitsa. Iwo adatsimikiza kuti maanja omwe ali ndi vuto la kubereka ayenera kuphunzitsidwa za kuopsa kwa zakudya.
Zakudya zingasokoneze chipambano cha chithandizo cha amuna ndi akazi, mogwirizana ndi zopezedwa m’mbuyomo zakuti “kudya mobwerezabwereza zakudya zamafuta monga zanyama kapena mkaka kukhoza kuwononga kwambiri umuna, pamene zipatso zina ndi ndiwo zamasamba zingawongolere ubwino wa umuna. Zapezekanso kuti ntchito yoteteza masamba ndi zipatso imagwirizana ndi antioxidants ndi zakudya zomwe zili nazo.
Kodi mayi angadye bwanji nyama ya ng'ombe? Amakhulupirira kuti izi zimachitika chifukwa cha anabolic steroids omwe amadyetsedwa kwa nyama. Komabe, malinga ndi kafukufukuyu, ma steroid amatha kuyanjananso ndi xenobiotics - mankhwala a mafakitale omwe amapezeka mu nyama, monga mankhwala ophera tizilombo ndi dioxin, komanso mankhwala omwe angakhalepo mu pulasitiki yomwe imakulunga zinthu.
Zitsulo zolemera zingathandizenso. Mtovu ndi cadmium sizimathandizira kuti pakhale kutenga pakati. Kodi mankhwala amenewa amalowa kuti m’thupi mwathu? Mitundu yambiri yazakudya zam'madzi zomwe zimagulitsidwa m'misika ya nsomba ndi masitolo akuluakulu zayesedwa. Mitundu yambiri ya cadmium yapezeka mu tuna ndi lead mu scallops ndi shrimp. Choncho, chidziwitso choperekedwa kwa anthu chokhudza kuopsa kwa nsomba (makamaka mercury) sichimapereka chithunzi chonse. Mu nsomba muli zitsulo zina zapoizoni.
