Monga momwe tikudziwira, nthawi zambiri kukoma kokoma kwa zakudya zosiyanasiyana kumabwera chifukwa cha kupezeka kwa zakudya monga zakudya monga sugarrose (chinthu ichi chimadziwika kwambiri kwa ife tsiku ndi tsiku monga shuga), komanso shuga ndi fructose. Zakudya zamadzimadzi ndizofunika kwambiri zowonjezera zakudya. Kukwanira kunena kuti kuchuluka kwa mphamvu zomwe thupi limagwiritsa ntchito kuti lichite zochitika zosiyanasiyana za thupi zimapangidwa ndi chimbudzi cha zakudya m'thupi. Kudyetsa chakudya chokwanira m'thupi ndi chakudya kumayambitsa mavuto omwe amagwiritsidwa ntchito pokonzanso mankhwala osokoneza bongo (carbon dioxide ndi madzi). Zakudya zosasunthika zimasandulika kukhala mafuta ndipo zimasungidwa mu minofu ya adipose. Choncho, zikuwonekeratu kuti kuchuluka kwa chakudya kumayambitsa kulemera kwa thupi.
Chifukwa cha chakudya chambiri, mapulogalamu osiyanasiyana amathandiza thupi lathu kukhala ndi makilogalamu ambiri, omwe sagwiritsidwa ntchito mokwanira popereka njira zofunika. Kuchuluka kwa zinthu zimenezi kumapangitsa kuti maonekedwe a mafuta ambiri awonongeke, zomwe zimakhudza kwambiri chikhalidwe cha chiwerengerocho.
Ndipotu, kalori yokhutira yamagazi sizitanthauza kuti muyenera kuchepetsa kusamwa kwa maswiti kuti mupeze chakudya. Mwachitsanzo, ndizololedwa kuwonjezera imodzi kapena awiri spoonfuls shuga ndi kapu ya tiyi mumaikonda kapena khofi. Kuonjezerapo, shuga yomwe imapezeka m'thupi panthawi ya mapangidwe a zakudya zovuta kwambiri ndi ofunikira kwambiri kuti zikhale zogwirira ntchito minofu ndi mitsempha ya mitsempha. Kutulutsidwa kwathunthu kwa shuga kuchokera ku chakudya (molecule yomwe imakhala ndi mafupa a shuga ndi fructose) kumabweretsa kufooka mofulumira ndipo kumapangitsa kuti kuchepa kwakukulu bwino.
Monga taonera kale, maswiti ambiri ali ndi shuga wochulukirapo, ndipo thupi ili ndi mavitamini pafupifupi 100%. Ndipo tsopano kumbukirani kuti maswiti otere monga maswiti, phokoso kapena ubweya wonyezimira amakhala pafupifupi ndi shuga m'njira zosiyanasiyana. Pogwiritsa ntchito ngakhale zakudya zing'onozing'ono izi, timapanga chiopsezo chokwanira kwambiri. Ngati simungakhoze kuiwala za maswiti pa tebulo lanu, yesetsani kuwadyetsa m'mawa, monga momwe zilili m'magazi amagazi adzakhala ndi nthawi yopatukana ndi mphamvu. Chifukwa chaichi, mwayi wolemera kwambiri umakhala wochepa poyerekezera ndi kudya chakudya madzulo.
Koma kodi zomwe tatchulazi zikutanthauza kuti maswiti onse amachititsa kuti pakhale mawonekedwe owonjezera thupi? Ngati mukufuna kukhala ndi anthu ochepa komanso osaphunzira, koma simunakonzekere kugawana ndi zakudya zomwe mumazikonda panthawi imodzimodzi, muli ndi njira imodzi yokha: kugwiritsa ntchito maswiti pogwiritsira ntchito shuga olowa m'malo mwawo (mwachitsanzo, saccharin). Zina mwa zinthu zimenezi ndizowonjezera kuposa shuga zonse zomwe zimadziwika makumi khumi kapena mazana ambiri, kotero kukhalapo kwazing'ono kwambiri zamagulu mu chakudya kumapangitsa mbale iliyonse yokoma. Komabe, kugwiritsa ntchito njira zoterezi ndizosavuta kwambiri komanso kwa nthawi yochepa.
