Ocwaningweni lwangemva kweminyaka engama-30 olubizwa ngokuthi “umthwalo womhlaba wonke wezifo,” ososayensi baqoqe imininingwane eminingi kakhulu ngokudla kwabantu emhlabeni jikelele. Kusukela ngo-1990 kuya ku-2017, ososayensi baqoqa idatha ngokudla kwezigidi zabantu emhlabeni jikelele.
Imininingwane elinganiselwe yabantu abaneminyaka engama-25 nangaphezulu - indlela yabo yokuphila, indlela abadla ngayo, nembangela yokufa.
Ukuvulwa okukhulu kwalomsebenzi omkhulu ukuthi eminyakeni edlule, ngenxa yezifo ezihambisana nokungondleki, kwafa kubantu abayizigidi eziyi-11, nasemiphumeleni yokubhema - izigidi eziyi-8.
Igama elithi “ukudla okungafanele” lisho ukuthi abukho ubuthi obungahlosiwe kanye nezifo ezingamahlalakhona (isifo sikashukela sohlobo 2, ukukhuluphala, isifo senhliziyo, nemithambo yegazi), okubangela - ukudla okungalingani.
Izici eziyinhloko ezintathu zokungondleki
1 - ukusetshenziswa ngokweqile kwe-sodium (usawoti ngokuyinhloko). Kubulale abantu abayizigidi ezintathu
2 - ukungabi khona kokusanhlamvu okuphelele ekudleni. Ngenxa yalokhu, iphinde yahlushwa izigidi ezintathu.
3 - ukusetshenziswa okuphansi kwezithelo kwezigidi ezimbili.
Ososayensi baphinde bathola ezinye izinto zokungondleki:
- ukusetshenziswa kancane kwemifino, okusanhlamvu, amantongomane nembewu, imikhiqizo yobisi, i-fiber yokudla, i-calcium, ama-marine omega-3 fatty acids,
- ukusetshenziswa kakhulu kwenyama, ikakhulukazi imikhiqizo egayiwe evela enyameni (amasoseji, imikhiqizo ebhenywayo, imikhiqizo eseqediwe, njll.)
- iziphuzo zothando, ushukela, nemikhiqizo equkethe amafutha e-TRANS.
Ngokuphawulekayo, ukudla okungafanele kwakuyimbangela eyingozi yokufa ngaphambi kwesikhathi, kudlula ngisho nokubhema.
