Kusala kudya nthawi zambiri kumagwiritsidwa ntchito ngati njira yabwino yochepetsera thupi, koma kumathandizanso thupi kulimbana ndi matenda. Kusala kudya kwa masiku awiri okha kumapangitsa kuti maselo a chitetezo cha mthupi abwererenso, kuthandiza thupi kulimbana ndi matenda.
Asayansi ku yunivesite ya Southern California anayesa zotsatira za 2-4 masiku kusala kudya mbewa ndi anthu maphunziro kwa miyezi isanu ndi umodzi. Pazochitika zonsezi, pambuyo pa maphunziro aliwonse, kuchepa kwa maselo oyera a magazi m'magazi kunalembedwa. Mu mbewa, chifukwa cha kusala kudya, kubwezeretsedwa kwa maselo oyera a magazi kunayambika, motero kubwezeretsa njira zotetezera thupi. Walter Longo, pulofesa wa gerontology and biological sciences pa yunivesite ya Southern California, anati: “Kusala kudya kumapereka kuwala kobiriwira kuonjezera chiwerengero cha maselo a tsinde, kubwezeretsa dongosolo lonse. Nkhani yabwino ndiyakuti posala kudya, thupi limachotsa maselo akale owonongeka. Kafukufukuyu adawonetsanso kuti kusala kudya kumachepetsa kupanga kwa hormone IGF-1, yomwe imakhudzana ndi chiopsezo cha khansa. Mayesero ang'onoang'ono oyendetsa ndege adapeza kuti kusala kudya kwa maola 72 asanalandire chithandizo chamankhwala kumalepheretsa odwala kukhala poizoni. “Ngakhale kuti mankhwala amphamvu amapulumutsa miyoyo, si chinsinsi kuti alinso ndi zotsatirapo zake pa chitetezo chamthupi. Zotsatira za kafukufukuyu zimatsimikizira kuti kusala kudya kungachepetse zotsatira za mankhwala a chemotherapy,” akutero Tanya Dorff, pulofesa wothandizira wa zachipatala pa yunivesite ya Southern California. "Kafukufuku wowonjezereka wachipatala akufunika pamutuwu ndipo zakudya zamtunduwu ziyenera kuchitika motsogoleredwa ndi dokotala."
