Mafuta a Trans ndi oipa. Akhoza kuonjezera ngozi ya matenda a mtima, imfa yadzidzidzi, matenda a shuga, ndipo mwinanso matenda a maganizo. Mafuta a Trans amalumikizidwa ndi khalidwe laukali, kusaleza mtima, ndi kukwiya.
Mafuta a trans amapezeka kwambiri pamalo amodzi okha m'chilengedwe: m'mafuta a nyama ndi anthu. Makampani opanga zakudya, komabe, apeza njira yopangira mafuta oopsawa mwa kukonza mafuta a masamba. Mwanjira imeneyi, yotchedwa hydrogenation, maatomu amakonzedwanso kuti azichita zinthu ngati mafuta a nyama.
Ngakhale kuti America nthawi zambiri amadya mafuta ambiri opangidwa kuchokera ku zakudya zokonzedwanso zomwe zimakhala ndi mafuta ochepa a hydrogenated, gawo limodzi mwa magawo asanu mwa mafuta a trans muzakudya zaku America ndizochokera ku nyama. Tsopano popeza mizinda ngati New York yaletsa kugwiritsa ntchito mafuta ochepa a hydrogenated, kugwiritsa ntchito mafuta opangidwa ndi mafuta opangidwa kukucheperachepera, pafupifupi 50 peresenti yamafuta aku America aku America tsopano akuchokera kuzinthu zanyama.
Ndi zakudya ziti zomwe zili ndi mafuta ochulukirapo ambiri? Malinga ndi nkhokwe ya dipatimenti ya Nutrients, tchizi, mkaka, yoghurt, ma hamburgers, mafuta a nkhuku, nyama ya turkey ndi agalu otentha omwe ali pamwamba pa mndandanda ndipo ali ndi mafuta pafupifupi 1 mpaka 5 peresenti.
Kodi mafuta a trans ndi vuto? Bungwe lodziwika bwino la sayansi ku United States, National Academy of Sciences, latsimikiza kuti njira yokhayo yotetezeka yamafuta a trans ndi ziro.
M’lipoti loletsa kudya mafuta owonjezera, asayansi sanathe n’komwe kugaŵira mlingo wokwanira wololedwa kudya tsiku ndi tsiku, chifukwa “kudya kulikonse kwa mafuta owonjezera kumawonjezera ngozi ya matenda a mtima.” Kungakhalenso kosayenera kudya mafuta a kolesterolini, kusonyeza kufunikira kochepetsa zakudya zanyama.
Kafukufuku waposachedwa amatsimikizira lingaliro lakuti kudya mafuta a trans, mosasamala kanthu za gwero la nyama kapena mafakitale, kumawonjezera chiopsezo chokhala ndi matenda a mtima, makamaka mwa amayi, monga momwe zimakhalira. "Chifukwa kugwiritsa ntchito mafuta ochulukirapo sikungapeweke m'zakudya zabwinobwino, zopanda nyama, kuchepetsa kudya kwamafuta mpaka zero kudzafunika kusintha kwakukulu pamalamulo azakudya," lipotilo likutero.
Mmodzi wa olembawo, mkulu wa Harvard University Cardiovascular Programme, anafotokoza momveka bwino chifukwa chake, mosasamala kanthu za izi, samalangiza zakudya zamasamba: "Sitingathe kuuza anthu kuti asiye nyama ndi mkaka," adatero. Koma titha kuuza anthu kuti azidya zamasamba. Tikadakhala ozikidwa pa sayansi, tikadawoneka onyada. ” Asayansi safuna kudalira sayansi yokha, sichoncho? Komabe, lipotilo likunena kuti kudya kwa trans fatty acids kuyenera kuchepetsedwa momwe kungathekere, pamene kudya zakudya zopatsa thanzi n'kofunika.
Ngakhale mutakhala wokonda zamasamba, muyenera kudziwa kuti pali ming'alu m'malamulo olembera omwe amalola kuti zakudya zokhala ndi mafuta ochepera 0,5 magalamu pa chakudya chilichonse zizilembedwa "zopanda mafuta." Zolembazi zimasokoneza anthu polola kuti zinthu zizilembedwa kuti alibe mafuta, pomwe sizili choncho. Chifukwa chake, kuti mupewe mafuta onse, dulani nyama ndi mkaka, mafuta oyengedwa bwino, ndi chilichonse chokhala ndi zosakaniza za hydrogenated, mosasamala kanthu za zomwe lembalo likunena.
Mafuta osayengedwa, monga mafuta a azitona, amayenera kukhala opanda mafuta a trans. Koma zotetezeka kwambiri ndizo magwero a chakudya chathunthu amafuta, monga azitona, mtedza, ndi njere.
