Pali nthano zambiri zonena za kuopsa kwa zakudya zina. Nthano zimenezi si kanthu poyerekeza ndi kuopsa kwenikweni kwa trans mafuta ndi carcinogens. Awiriwo nthawi zambiri amasokonezeka. Mwachitsanzo, zikanenedwa kuti mafuta a masamba amasanduka mafuta akamawotcha. M'malo mwake, imakhala ndi okosijeni chifukwa cha kutentha kwambiri ndipo imakhala carcinogenic. Kodi pali kusiyana kotani pakati pa mafuta a trans ndi ma carcinogens ndipo kuopsa kwawo ndi kotani?
Mafuta a Trans mu zakudya
Pazolemba zazakudya, mafuta a trans amatha kuwoneka pansi pa mayina a margarine, tallow yopangidwa, mafuta a masamba a hydrogenated. M'makampani azakudya, amagwiritsidwa ntchito ngati analogue yotsika mtengo ya batala.
Margarine amaphatikizidwa muzinthu zambiri za confectionery - mu makeke, makeke, makeke, pie, maswiti. Amawonjezeredwa ku mkaka wa mkaka - ma curds, curds, kanyumba tchizi, ayisikilimu, kufalikira. Opanga osasamala samawonetsa margarine pa chizindikirocho, koma amangolemba "mafuta amasamba". Ngati mankhwalawa ndi olimba, samathamanga ndipo samataya mawonekedwe, ndiye kuti alibe mafuta a masamba, koma margarine.
Margarine ali ndi mafuta ochuluka koma amapangidwa kuchokera ku mafuta a masamba osatha. Panthawi yopanga, ma molekyulu a unsaturated mafuta acid amachotsedwa pawiri, kuwapanga kukhala mafuta odzaza. Koma si kusintha kumeneku komwe kuli koopsa kwa thanzi, koma kuti zotsatira zake zinali kusintha kwa molekyulu yokha. Zotsatira zake ndi mafuta omwe kulibe m'chilengedwe. Thupi la munthu silingathe kuchikonza. Thupi lathu lilibe "mnzako / mdani" wozindikiritsa mafuta, motero mafuta osinthika amaphatikizidwa m'njira zosiyanasiyana zamoyo. Choopsa chake ndi chakuti pamene molekyu yosinthidwa ikalowa mu selo, imasokoneza ntchito zake, zomwe zimadzaza ndi kusokonezeka kwa chitetezo cha mthupi, kagayidwe kake, kunenepa kwambiri komanso kukula kwa zotupa.
Kodi mungadziteteze bwanji ku mafuta a trans?
- Chotsani zakudya zopatsa thanzi, maswiti, zophika ndi mkaka womwe ungakhale wowopsa m'zakudya;
- Werengani mosamala malembawo - ngati zolembazo zili ndi "mafuta amasamba", koma mankhwalawo ndi olimba, ndiye kuti mapangidwewo alibe batala, koma margarine.
Zinthu za Carcinogenic
Carcinogen ndi chinthu chomwe chimayambitsa khansa. Ma carcinogens amapezeka osati muzakudya zokha. Iwo ali m'chilengedwe, mafakitale, ndipo amapangidwa ndi zochita za anthu. Mwachitsanzo, ma X-ray ndi carcinogenic, utsi wa fodya, nitrates ndi nitrites nawonso.
Pankhani ya zakudya, anthu amawononga matupi awo akamagwiritsa ntchito mafuta a masamba osayengedwa kuti azikazinga kapena kukazinganso mumafuta oyengeka. Mafuta osayengedwa amakhala ndi zonyansa zomwe sizingagwirizane ndi kutentha kwakukulu - zikatenthedwa, zimakhala zowononga. Mafuta oyengedwa amatha kupirira kutentha kwambiri, koma kamodzi kokha.
Pakati pazakudya zomalizidwa, atsogoleri omwe ali ndi ma carcinogens ndi zinthu zosuta zomwe zimakhala ndi poizoni wa polycyclic hydrocarbon kuchokera ku utsi.
Zakudya zosiyanasiyana zam'chitini, kuphatikizapo pickle zopangira tokha, zimakhalanso ndi zinthu zovulaza. M'makampani azakudya, zoteteza zowononga zitha kugwiritsidwa ntchito, ndipo masamba otsika amatha kugwiritsidwa ntchito pokonzekera zopangira kunyumba. Ngati masamba amabzalidwa pa feteleza apadera amchere, ndiye kuti ali ndi ma nitrate, omwe, akasungidwa kapena kusungidwa pamalo otentha, amakhala owopsa kwambiri.
Kodi mungadziteteze bwanji ku ma carcinogens?
- Mwachangu mu mafuta oyengedwa, koma musagwiritsenso ntchito;
- Chepetsani zinthu zosuta komanso zakudya zam'chitini momwe mungathere;
- Yang'anani zolemba zazakudya zamzitini. Ndi bwino ngati zikuchokera lili zoteteza zachilengedwe monga mchere ndi viniga.
Tsopano mukudziwa zomwe mafuta a trans ndi carcinogens ali, komanso zakudya zomwe zimapezeka. Izi zikuthandizani kuti musinthe kwambiri zakudya zanu ndikuchepetsa chiopsezo cha matenda osasinthika.
