Simbi isingatsvigiri yemhando yezvekudya chinhu chakakosha mukugadzirwa kwemidziyo yekicheni, midziyo, uye michina yekugadzirisa chikafu. Kunzwisisa mitemo inotsanangura simbi isingatsvigiri yemhando yezvekudya kwakakosha pakuona kuchengetedzeka uye kunaka kwezvigadzirwa zvine chekuita nechikafu.
Chinonyanya kukosha pakutsanangura simbi isingatsvedzeri seyemhando yechikafu chiri mukugadzirwa kwayo. Simbi isingatsvedzeri yechikafu inofanira kunge iine zvinhu zvakasiyana-siyana zvinoenderana nezvinodiwa pasi rose. Zvinhu zvinonyanya kushandiswa zvinosanganisira 304, 316, uye 430, uye 304 ndiyo inonyanya kufarirwa nekuda kwekusagadzikana kwayo nengura uye kugara kwenguva refu.
Chimwe chinhu chakakosha chesimbi isingatsvedzeri chikafu ndechekudzivirira kwayo ngura nengura. Izvi zvinoita kuti zvinhu izvi zvisasanganiswe nechikafu chine acidic kana alkaline, zvichidzivirira kupinda kwezvinhu zvinokuvadza muchikafu. Chromium iri musimbi isingatsvedzeri inoita kuti idzivirire, zvichiita kuti isatsvedzere ngura uye ikwanise kusangana nechikafu.
Kutsvedzerera uye hutsanana zvinhu zvakakoshawo pamutengo wesimbi isingatsvedzeri yemhando yezvekudya. Kupenya kwesimbi isingatsvedzeri kunofanira kunge kwakapfava uye kusina zvikanganiso zvinogona kukonzera mabhakitiriya. Izvi zvinoita kuti zvive nyore kuchenesa nekuchengetedza hutsanana hwemidziyo yekugadzira chikafu, zvichiita kuti pasave nechinhu chinosvibisa chikafu.
Kusavapo kwezvinhu zvinokuvadza chimwe chinhu chakakosha. Simbi isingatsvedzeri yemhando yezvekudya haifanirwe kunge iine zvinhu zvakaita semutobvu, cadmium, kana zvimwe zvinhu zvine chepfu zvinogona kukonzera njodzi kuhutano kana zvasangana nechikafu. Maitiro akaomarara ekuyedza uye ekupa zvitupa aripo kuti ave nechokwadi chekuti simbi isingatsvedzeri inosangana nezvinodiwa izvi zvekuchengetedza.
Indasitiri iyi inosimbisawo kukosha kwekutevedzera mitemo yakaita seFood and Drug Administration (FDA) muUnited States nemasangano akafanana pasi rose. Kutevedzera mitemo iyi kunoita kuti zvigadzirwa zvesimbi isina ngura zvemhando yepamusoro zvisvike pakuchengetedzwa kwepamusoro uye pamhando yepamusoro.
Mukupedzisa, mitemo yesimbi isingatsvedzeri yemhando yezvekudya inotenderera pakugadzirwa kwayo, kuramba ngura, nzvimbo dzakatsetseka, uye kusavapo kwezvinhu zvinokuvadza. Nekutevedzera mitemo iyi, vagadziri vanogona kugadzira midziyo yekicheni nemidziyo isingangogari kwenguva refu chete asiwo yakachengeteka pakubata chikafu, zvichipa vatengi chivimbo chekuti zvishandiso zvavo zvekubika zvinosangana nezvinodiwa zvemhando yepamusoro.
Chitofu chedu chesimbi isina ngura hachingogumiri pahunhu hwataurwa pamusoro apa chete, asiwo chine zvakanakira "zvemhando yepamusoro uye mutengo wakanaka kwazvo". Chitofu chedu chesimbi isina ngura chinotengeswa kunyika dzakawanda pasi rose, zvichipa chitofu chemhando yepamusoro kumhuri dzakawanda nemabhizinesi. Tinokugamuchirai kuchitoro kuti mutenge.
