Besisoloko silunyukiswa ngeengozi zokutya ityuwa eninzi ekutyeni kwethu, kodwa inye uphando olupapashwe kwiLancet iqinisekisa ukuba ukuyithatha ayibangeli ukwanda kwezifo zentliziyo. Siza kujongana nengcebiso entsha yokutya, evunywe ngoogqirha abadumileyo baseBritane.
Kukho umngcipheko kuphela xa uthatha ngaphezu kwe-5 grams ngosuku
Uphononongo luqhutywe kumazwe ali-18 eMelika, eYurophu, e-Afrika, e-Asia, kwiMpuma Ekufuphi nakwiMpuma Ekude; kwaye umngcipheko wokubandezeleka kwezifo zentliziyo ngenxa yokusetyenziswa kwetyuwa uyanqatshelwa. Iingcali zenzululwazi zithi kukho ingozi kuphela xa udlula i-5 grams yesodium ngosuku (malunga ne-2 kunye nesiqingatha setipuni). Kuyamangalisa ukuba lo mthamo usetyenziswa kuphela I-5% yabemi.
Uphando lubonise ukuba ukutya ukutya okutyebileyo kwiziqhamo, imifuno, iimveliso zobisi, iitapile, amandongomane kunye nokunye ukutya okunomxholo ophezulu we-potassium ukubuyisela umva kwaye kunokuphelisa ukubakho kokubandezeleka kwisifo senhliziyo esidityaniswe nokusetyenziswa kwetyuwa.
Kuwo onke amazwe athathe inxaxheba, iTshayina yaba kuphela apho i-80% yabemi igqithise ityuwa yemihla ngemihla. Kwezinye, kuqhelekile ukutya phakathi kweegram ezintathu ukuya kwezintlanu ngosuku.
Iingcebiso ze-WHO
I-World Health Organization incoma ukuthatha thabatha iigram ezimbini yonke imihla (icephe elinye) njengomlinganiselo wokuthintela isifo sentliziyo. I-American Heart Association, ngakolunye uhlangothi, icebisa ukuba incitshiswe ibe yeyona inconywayo 1 grams yonke imihla.
Kodwa ukunciphisa ukusetyenziswa kwetyuwa akusoloko kulungile. Omnye wabaphandi kuphononongo okhankanywe ngasentla uthi “Akukho bungqina obuninzi bokuthi ukukhawulela ukungena kwetyuwa kule ngongoma kukhokelela ekuphuculweni kweemeko zempilo, nangona kweli nqanaba lincinci.«.
«Iziphumo zethu zibonisa ukuba amaphulo okunciphisa ukusetyenziswa kwetyuwa kufuneka agxininise kuphela kuluntu oludlula ukusetyenziswa kwalo; kwaye kufuneka ibe yinxalenye yeendlela ezibanzi zokuphucula umgangatho wokutya ngokubanzi«.
