Selo lililonse m'thupi lathu limafuna mphamvu zokhazikika. Zakudya zama carbohydrate ndiye gwero lofunikira kwambiri lamafuta ku ubongo, mtima, minofu ndi dongosolo lapakati lamanjenje. Zakudya zambiri zimachokera ku zakudya zochepa zama carbohydrate kuti muchepetse thupi, koma zotsatira za zakudya zotere zimakhala zotsutsana. Muzakudya zoterezi, kusowa kwa mphamvu kumasinthidwa ndi mapuloteni ambiri ndi mafuta. Zimenezi zimabweretsa mavuto, matenda a mtima, m`mimba thirakiti, ndi zina zotero. Zakudya zama carbohydrate zimagayidwa ndikuphwanyidwa kukhala glucose. Glucose amasungidwa m'magazi ngati gwero lachindunji lamafuta m'thupi. Zofunikira zamphamvu zikakwaniritsidwa, shuga wowonjezera amasungidwa m'chiwindi ndi minofu mu mawonekedwe a glycogen. Ma carbohydrate akasowa, chiwindi chimaphwanya glycogen kuti itulutse shuga. Ma carbohydrate amagawidwa m'magulu zosavuta komanso zovuta.
Zakudya za mkaka, zipatso ndi ndiwo zamasamba ndizomwe zimapereka mavitamini, mchere, antioxidants ndi fiber. Zakudya zopatsa thanzi komanso shuga woyengedwa bwino, zomwe nthawi zambiri zimapezeka m’masiwiti, makeke, ufa woyera, ndi zakumwa zotsekemera, zilibe michere yambiri ndipo—starchis—ali ndi mavitamini A, C, E, ndi K ambiri, vitamini B complex, potaziyamu, iron, ndi magnesium. . Mkate wathunthu wambewu, chimanga, nyemba, masamba owuma, mtedza ndi njere ndi magwero abwino kwambiri amafuta ovuta omwe alinso ndi fiber. Zakudya zokhala ndi fiber zambiri zimalepheretsa matenda a shuga, kudzimbidwa, kunenepa kwambiri, komanso khansa ya m'matumbo. Kuchepetsa kovomerezeka kwa zakudya zama carbohydrate ndi . Akuluakulu azaumoyo amavomereza kuti chakudya chiyenera kukhala chakudya.
