Mu kafukufuku wazaka 30 wotchedwa "Global Burden of Disease," asayansi asonkhanitsa zambiri zokhudzana ndi zakudya za anthu padziko lonse lapansi. Kuyambira 1990 mpaka 2017, asayansi adasonkhanitsa zambiri pazakudya za anthu mamiliyoni ambiri padziko lonse lapansi.
Chiŵerengero cha anthu a zaka 25 ndi kuposerapo - moyo wawo, zakudya, ndi chifukwa cha imfa.
Kutsegula kwakukulu kwa ntchito yaikuluyi kunali kuti kwa zaka zambiri, kuchokera ku matenda okhudzana ndi kuperewera kwa zakudya m'thupi, anafa pa anthu 11 miliyoni, ndi zotsatira za Kusuta - 8 miliyoni.
Mawu akuti "zakudya zosayenera" amatanthauza kuti palibe poizoni wosakonzekera ndi matenda aakulu (mtundu wa shuga 2, kunenepa kwambiri, matenda a mtima, ndi mitsempha ya magazi), zomwe zimayambitsa - zakudya zopanda thanzi.
3 zifukwa zazikulu za kuperewera kwa zakudya m'thupi
1 - mowa wambiri wa sodium (mchere makamaka). Inapha anthu 3 miliyoni
2 - kusowa kwathunthu mbewu mu zakudya. Chifukwa cha izi, idavutikanso ndi 3 miliyoni.
3 - otsika kumwa zipatso 2 miliyoni.
Asayansiwo adazindikiranso zifukwa zina zomwe zimayambitsa kuperewera kwa zakudya m'thupi:
- Kuchepetsa kudya masamba, nyemba, mtedza ndi mbewu, mkaka, ulusi wamafuta, calcium, omega-3 fatty acids am'madzi,
- kudya kwambiri nyama, makamaka zopangidwa kuchokera ku nyama (soseji, zinthu zosuta, zinthu zomwe zatha, etc.)
- zakumwa zoledzeretsa, shuga, ndi zinthu zomwe zili ndi mafuta a TRANS.
Chochititsa chidwi n'chakuti, zakudya zosayenera ndizomwe zimayambitsa kufa msanga, kuposa Kusuta fodya.
