• Nyama, hove, uye huku
• Zvigadzirwa zvemukaka
• Mimwe michero nemiriwo

Zvimwe zvekudya zvinowedzera zvine vhitamini A.

Zvekuwedzera ndizvo zvakanyanya kukonzera vhitamini A chepfu. Izvo zvinowanzoitika zvisingaitike chete kubva pakudya vhitamini A-zvakapfuma zvekudya.

Kuwanda kwevhitamini A kunogona kukurwarisa. Kutora madhiri makuru panguva yekuzvitakura kunogona kukonzera hurema hwekuzvara.

• Acute vhitamini A chepfu inoitika nekukurumidza. Zvinogona kuitika kana munhu mukuru akatora mazana emazana ezviuru epasi rese mauniti (IUs) evhitamini A.
• Chisingaperi vhitamini A chepfu inogona kuitika nekufamba kwenguva muvakuru vanogara vachitora anopfuura 25,000 IU pazuva.
• Vacheche nevana vanonyanya kufunga nezvevhitamini A. Vanogona kurwara mushure mekutora zvidiki zvacho. Kumedza zvigadzirwa zvine vhitamini A, senge ganda remakanda rine retinol mariri, zvinogona zvakare kukonzera huturu hwevhitamini A.

Zviratidzo zvinogona kusanganisira:

• Kunyorovesa kusanzwisisika kwedehenya bone (mune vacheche nevana)
• Kuona kwakashata
• Kurwadziwa kwepfupa kana kuzvimba
• Kubhururuka kwenzvimbo yakapfava mudehenya remucheche (fontanelle)
• Shanduko mukusvinura kana kuziva
• Kuderedza kudya
• Dzungu

• Ropa bvunzo kutarisa vhitamini A chiyero
• Ropa bvunzo kutarisa mamwe mavhitamini

Kurapa kunosanganisira kungomisa zvinowedzera (kana mune zvisingawanzoitika zviitiko, zvekudya) zvine vhitamini A.

Vanhu vazhinji vanopora zvizere.

Zvinetso zvinogona kusanganisira:

• Yakakwirira kwazvo calcium level
• Kukundikana kubudirira (muvacheche)
• Itsvo kukuvara nekuda kwakakwira calcium
• Kukuvara kwechiropa

Kutora yakawandisa vhitamini A panguva yekuzvitakura kunogona kukonzera kuremara kwekuberekwa. Taura nemupi wako wezvehutano nezve kudya kudya kwakakodzera iwe uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchwarira uchiita izvi.

Iwe unofanirwa kufonera mupi wako:

• Kana iwe uchifunga kuti iwe kana mwana wako munogona kunge makatora zvakawandisa vhitamini A
• Iwe une zviratidzo zvekuwedzeredza vhitamini A

Yakawanda sei vhitamini A yaunoda zvinoenderana nezera rako uye bonde. Zvimwe zvinhu, sekubata pamuviri uye hutano hwako hwese, zvakakoshawo. Kumbira mupiki wako kuti ndeipi mari yakakunakira iwe.

Kuti udzivise hypervitaminosis A, usatore zvinopfuura zvinokurudzirwa zuva nezuva zvevhitamini iyi.

Vamwe vanhu vanotora vhitamini A uye beta carotene zvinowedzera mukutenda kuti zvinobatsira kudzivirira cancer. Izvi zvinogona kutungamira kune risingaperi hypervitaminosis A kana vanhu vakatora zvinopfuura zvinokurudzirwa.
