Ndikofunika kuti azidya moyenera ndipo, choyamba, asadye mapuloteni a nyama. Kenaka thupi la mwanayo lidzakula monga momwe liyenera kukhalira mwachibadwa, ndipo munthu woteroyo adzapewa matenda ambiri okonzekera omwe amadya nyama.
USDA ndi American Dietetic Association amathandizira kwambiri makolo omwe amapatsa ana awo chakudya chamagulu basi. Kafukufuku akusonyeza kuti ana amene sadya nyama amakhala athanzi kwambiri kuposa anzawo. Ali ndi chiopsezo chocheperako ka 10 chokhala ndi matenda amtima. Inde, ali ndi zaka zitatu, ana omwe amadya mwachizolowezi amakhala ndi mitsempha yotsekeka! Komanso, ngati mwana adya nyama, amakhala ndi mwayi wotenga khansa kuwirikiza kanayi - ndipo atsikana ali ndi mwayi wokhala ndi khansa ya m'mawere nthawi zinayi!
Kafukufuku wofalitsidwa mu Journal of the American Dietetic Association amasonyeza kuti ana omwe sanadyetsedwe zakudya za nyama kuyambira pa kubadwa ali ndi IQ yomwe ili pamwamba pa 17, pafupifupi, kuposa anzawo omwe amadya nyama, mkaka, ndi mazira. Kafukufuku yemweyo akugwirizanitsa kumwa mkaka ali mwana ndi matenda monga colic, matenda a khutu, matenda a shuga omwe amadalira insulini, kudzimbidwa, ndi kutuluka magazi mkati. Frank Oski, wapampando wa za ana pa yunivesite ya Johns Hopkins, anati: “Palibe chifukwa chomamwa mkaka wa ng’ombe pa msinkhu uliwonse.

Zimayambitsa ziwengo, kusadya bwino, ndipo nthawi zina zimayambitsa matenda a shuga paubwana.” Zochita zolimbitsa thupi ku Siberia ndi St. Amathetsa mosavuta mavuto ovuta a masamu, amaphunzira maphunziro ovuta ndi zigawo. Iwo ali ndi chikhumbo cha kulenga: kulemba ndakatulo, kujambula, kuchita zaluso (kusema matabwa, nsalu), etc.
Kuonjezera apo, makolo a ana otere omwe adasintha zakudya zoyera samamwa zakumwa zoledzeretsa, choncho nthawi zonse amakhala osamala komanso amamvetsera kwambiri ana awo. M’mabanja oterowo, nthaŵi zambiri mtendere ndi chikondi zimalamulira, zomwe zimakhudza kwambiri kukula kwa ana. Zochitika zapadziko lonse (India) zimatsimikizira kuti ana odyetsera zamasamba sakhala kumbuyo kwa anzawo, ndipo amawaposa potengera kupirira komanso kukana matenda. Kufunika kwa kudya mazira ndi nthano chabe yomwe ili kutali kwambiri ndi zenizeni zomwe anthu ambiri "amadyetsedwa" nazo.
