Munyu uri kuzununguswa munzvimbo yose uye zvidzidzo zvechangobva kuitika zvinopisa mazano pamusoro pezvino chaizvoizvo zvakakwana zvakakwana kudya zuva rega rega. Tanga tichirarama pasi pe "isina kunyanya munyu zviri nani" nekuda kwechirwere chepfungwa yemwoyo (CHD) uye kunyeverwa kwehutano kwemakumi emakore. Iye zvino isu tiri kurohwa nemafuta asina kukwana mukudya kwedu kunogona kukonzera matambudziko emwoyo nekufa.
IAmerican Journal of Hypertension yakabudisa uchapupu hunotsvakurudza hunotsanangura kuti "mune chimwe chekutanga kana kuwedzerwa kuongororwa kwaive kwakaderera kudya kwakanyanya kwemaitiro kunobatsira kune zvose-zvinokonzera kufa (ACM) kana cardio vascular disease (CVD)."
Sayenzi yakasimudza maoko uye, mukuedza kugadzirisa zvinhu, Centers for Disease Control uye Kudzivirira (CDC) yakabvunza Institute of Medicine (IOM) kuti iende pasi pezvokudya zveyerodium uye yehutano yehuwandu hwevanhu. Usati watora makoko ako uye uchitanga salting zvokudya usina kufunga, ngatishandire mune izvo sayenzi iri kutaura chaizvo pamusoro peiyi inokosha yemaminerari.
Tinoda Munyu
Munyu ine soda, chinhu chinokosha muviri unoda kushanda zvakanaka. Sodium inodzora ropa redu, ropa redu, uye inotora chikamu chinokosha mumitsipa yedu nemisumbu inoshanda zvakanaka.
Munyu unobatsira miviri yedu kuramba ichienzanisa uye yakasvibiswa kunyanya munguva yekurovedza muviri apo isu tiri kurasikirwa nemvura uye sodium kuburikidza neshutu. Munyu inowanzoitika mune zvimwe zvokudya zvakadai semiti, mishonga yemakaka , nyama, uye mavhisi akawanda anotengwa muchitoro.
Munyu unogunun'una hausi mutorwa kudya matafura apo yakawedzerwa sodium inowanikwa kune zvese izvo zvine salty. Mazano ekare ekuchikoro kuti awane munyu wa 1500mg kusvika kusati ma 2300mg zuva nezuva (pasi pe1 tsp yematafura munyu) iye zvino ari pachigaro chinopisa.
Kutsvakurudza Kuwedzerwa Kunodiwa
Tsvakurudzo haisi kureva kuti munyu wakawandisa wakanaka kune iwe-chero chinhu chakanyanyisa chinogona kunge chisina kunaka. Asi izvo zvavari kupikisa ndezvokuti "miganhu yakaderera yemunyu yekugadzirisa maererano nekuchengeteka haina kunyatsotsanangurwa."
Zvakazoitika ndezvokuti kudya kwakaderera kwemuori kunobatsira renin-angiotensin-aldosterone uye nenyasha dzenheyo dzinogona kuwedzera insulini yekudzivirira. Izvi zvinoreva kuti muviri unobereka insulini asi hauzive kuti ungashandisa sei zvakanaka uye unobatanidzwa kune dambudziko guru rezvirwere zvemoyo.
Dambudziko nekugadzira bvudzi remunyu kumativi ose emitambo yevanhu vose ndiyo ingangodaro isina kunge iri nzira yakanakisisa yekugadzirisa nyaya yakakura ye sodium inokonzera chirwere chemoyo. Ichokwadi pamusoro pekudya munyu kunodya zvakanyanya kana kuti zvishoma zvingakanganisa zvichienderana nemunhu.
The Institute of Medicine yasvika mberi ne "mamwe maitiro akaongororwa akaongororwa achadiwa, sezvo aya anomiririra hukuru hwepamhando yekugadzirisa maitiro ekugadzirisa zvinoitika zve sodium pamigumisiro yehutano." Uye, maererano neThe New England Journal of Medicine, "kududzira kusina hanya yemishonga zvinokonzerwa nevanotsvakurudza vanogona kutungamirira kumigumisiro isingatarisirwi uye zvinyorwa zvepapepanhau zvakadai se "Zvino Munyu Unodzivirirwa Kudya."
Nekuvhiringidzika kwose pamusoro pekugadzira munyu, kunyanya kutsvakurudza kunonyatsodikanwa kuongorora mazano anobva 1500 kusvika 2300mg emunyu seanobatsira vanhu vazhinji.
