Ukungatholi abantwana ukutholwa kwamaphesenti angu-10-15 emibhangqwana ezama ukukhulelwa, futhi cishe ingxenye yenkinga yindoda. Ucwaningo lwakamuva lwe-Harvard luthole ukuthi ukwanda ngamaphesenti angu-5 nje kokudla kwamafutha agcwele kuhlotshaniswa nokwehla kwamaphesenti angama-38 esibalweni sesidoda.
Kodwa kungani? Lokhu kungase kube ngenxa yokuphazamiseka kohlelo lwe-endocrine ngenxa yezinto ezingcolisa izimboni ezinqwabelana emafutheni ezilwane, ikakhulukazi amafutha ezinhlanzi, futhi kube nomthelela ekuzaleni kwabesilisa, hhayi nje ngokubala kwesidoda, kodwa nasendleleni esebenza kahle ngayo. .
Ucwaningo lwakamuva luthole ukuthi amathuba okukhulelwa ngempumelelo nokufaka iqanda elivundisiwe ayancipha ezigulini ezibike ukuthi zidla inyama kaningi. Abacwaningi bakholelwa ukuthi ukungcola kwezimboni nama-steroid atholakala emikhiqizweni yezilwane yikona okuyimbangela. Baphethe ngokuthi izithandani ezinenkinga yokukhulelwa kufanele zifundiswe ngemiphumela edabukisayo yokudla okunomsoco.
Ukudla kungase kuthinte impumelelo yokwelapha kwabesilisa nabesifazane, ngokuvumelana nokutholwe ngaphambili kokuthi “ukudla njalo ukudla okunamafutha njengemikhiqizo yenyama noma ubisi kungase kuthinte kabi izinga lesidoda, kuyilapho izithelo nemifino ethile kungase kuthuthukise izinga lesidoda. Kuphinde kwatholakala ukuthi umsebenzi wokuvikela wemifino nezithelo uhlobene nama-antioxidants kanye nezakhi eziqukethe.
Ukudla kukamama inyama yenkomo kungathinta kanjani ukukhula kwamasende endodana yakhe futhi kube nomthelela omubi ekuzaleni kwayo esikhathini esizayo? Kukholakala ukuthi lokhu kubangelwa ama-anabolic steroids anikezwa izilwane. Kodwa-ke, ngokocwaningo, ama-steroids angaphinde ahlanganyele namanye ama-xenobiotics - amakhemikhali ezimboni akhona enyameni, njengezibulala-zinambuzane kanye ne-dioxin, kanye namakhemikhali angase abe khona epulasitiki egoqa imikhiqizo.
Izinsimbi ezisindayo nazo zingadlala indima. Umthofu ne-cadmium nazo azifaki isandla ekukhulelweni okuphumelelayo. Angenaphi la makhemikhali emzimbeni wethu? Izinhlobo ezivame kakhulu zokudla kwasolwandle ezithengiswa ezimakethe zezinhlanzi nasezitolo ezinkulu sezihloliwe. Amazinga aphezulu e-cadmium atholwe ku-tuna kanye nomthofu kuma-scallops nezimfanzi. Ngakho, ulwazi olunikezwa umphakathi mayelana nezingozi ezihlobene nokusetshenziswa kwezinhlanzi (ikakhulukazi i-mercury) alunikezi isithombe esiphelele. Kunezinye izinsimbi ezinobuthi ezinhlanzini.
