Michero nemiriwo zviri mumagaba nezviri mufiriji zvinowanzoonekwa sezvisina hutano hwakakwana pane michero nemiriwo mitsva. Asi izvi handizvo zvazviri.
Kutengeswa kwechikafu chakabikwa mumagaba nechakachengetwa mufiriji kwakawedzera mumavhiki achangopfuura sezvo vatengi vakawanda vachitenga chikafu chinochengetwa musherufu. Kunyangwe kutengeswa kwefiriji kuri kuwedzera. Asi uchenjeri hwakajairika hunoshandiswa nevakawanda vedu ndehwekuti kana zvasvika pamichero nemiriwo, hapana chinovaka muviri kupfuura zvirimwa zvitsva.
Kudya zvinhu zvakabikwa mumagaba kana kuti zvakachengetwa muchando kwakaipa here pahutano hwedu?
Fatima Hachem, mukuru wezvekudya kuFood and Agriculture Organisation yeUnited Nations, akati kana zvasvika pamubvunzo uyu, zvakakosha kuyeuka kuti zvirimwa zvinonyanya kuva neutano panguva yazvinokohwewa. Zvirimwa zvitsva zvinoshanduka mumuviri, mumuviri uye makemikari kana zvangotorwa kubva muvhu kana pamuti, izvo zvinopa zvinovaka muviri nesimba.
"Kana miriwo ikaramba iri pasherufu kwenguva yakareba, kukosha kwekudya kwemiriwo mitsva kunogona kurasika kana yabikwa," akadaro Hashim.
Mushure mekutanha, muchero kana muriwo uchiri kudya nekupwanya zvinovaka muviri kuti masero awo arambe ari mupenyu. Uye zvimwe zvinovaka muviri zvinoparadzwa zviri nyore. Vhitamini C inobatsira muviri kupinza iron, kuderedza cholesterol uye kudzivirira kubva kumafree radicals, uye inonyanya kunzwa oxygen nechiedza.
Kuisa mufiriji zvigadzirwa zvekurima kunononotsa kuderera kwezvinovaka muviri, uye mwero wekurasikirwa kwezvinovaka muviri unosiyana kubva pachigadzirwa chimwe nechimwe.
Muna 2007, Diane Barrett, aimbove muongorori wesainzi yezvekudya netekinoroji paYunivhesiti yeCalifornia, Davis, akaongorora zvidzidzo zvakawanda pamusoro pehuwandu hwezvinovaka muviri zviri mumichero nemiriwo mitsva, yakaomeswa nechando, uye yakakangwa. . Akawana kuti sipinachi yakarasikirwa ne100 muzana yehuwandu hwayo hwevhitamini C mukati memazuva manomwe kana ikachengetwa patembiricha yemukamuri ye20 degrees Celsius (68 degrees Fahrenheit) uye 75 muzana kana ikachengetwa mufiriji. Asi kana tichienzanisa, makarotsi akarasikirwa ne27 muzana chete yehuwandu hwayo hwevhitamini C mushure mevhiki yekuchengetwa patembiricha yemukamuri.
