Ubwino Wathanzi

1. Okwera kwambiri mu PUFA Omega-6s, Makamaka Linoleic Acids

Kafukufuku wapeza kuti kuchuluka kwa mafuta a asidi mu mafuta a mphesa ndi linoleic acid (LA), mtundu wamafuta ofunikira - kutanthauza kuti sitingathe kupanga tokha ndipo tiyenera kupeza kuchokera ku chakudya. LA imasandulika kukhala gamma-linolenic acid (GLA) tikangogaya, ndipo GLA imatha kukhala ndi ntchito zoteteza mthupi.

Pali umboni wosonyeza kuti GLA imatha kuchepetsa kuchuluka kwa cholesterol ndi kutupa nthawi zina, makamaka ikasinthidwa kukhala molekyulu ina yotchedwa DGLA. Zitha kuthandizanso kuchepetsa chiwopsezo chopanga magazi owopsa chifukwa chakuchepetsa kwake pakuphatikizana kwa mapulateleti.

Kafukufuku wina wofalitsidwa mu International Journal of Food Science and Nutrition anapeza kuti poyerekeza ndi mafuta ena a masamba monga mafuta a mpendadzuwa, anali opindulitsa kwambiri pochepetsa kutupa ndi kukana insulini mwa akazi onenepa kwambiri kapena onenepa kwambiri.

Kafukufuku wina wa nyama adapezanso kuti kumwa mafuta amphesa kunathandizira kusintha mawonekedwe a antioxidant ndi mbiri yamafuta adipose acid (mitundu yamafuta osungidwa m'thupi pansi pa khungu).

2. Gwero Labwino la Vitamini E

Mafuta a mphesa ali ndi kuchuluka kwa vitamini E, yomwe ndi antioxidant yofunika yomwe anthu ambiri angagwiritse ntchito kwambiri. Poyerekeza ndi mafuta a azitona, ali ndi vitamini E wowirikiza kawiri.

Izi ndi zazikulu, chifukwa kafukufuku amasonyeza kuti phindu la vitamini E limaphatikizapo kuteteza maselo ku zowonongeka zowonongeka, kuthandizira chitetezo cha mthupi, thanzi la maso, thanzi la khungu, komanso ntchito zina zambiri zofunika za thupi.

3. Zero Trans Fat ndi Non-hydrogenated

Pakhoza kukhalabe mkangano wokhudza kuti mafuta amtundu wanji ali abwino kwambiri, koma palibe mtsutso wokhudza kuopsa kwa mafuta a trans ndi mafuta a hydrogenated, chifukwa chake ayenera kupewedwa.

Mafuta a Trans amapezeka nthawi zambiri muzakudya zosinthidwa kwambiri, zakudya zofulumira, zokhwasula-khwasula m'matumba ndi zakudya zokazinga. Umboniwo ndi woonekeratu kuti ndi woipa pa thanzi lathu kotero kuti amaletsedwa nthawi zina tsopano, ndipo ambiri opanga zakudya akudzipereka kuti asiye kuzigwiritsa ntchito bwino.

4. Ndipamwamba Utsi Point

Utsi wa utsi wa mafuta kapena mafuta ophikira umatanthawuza kutentha kwake kapena kutentha komwe mafuta amayamba kukhala oxidize, kusintha kapangidwe kake ka mankhwala molakwika. Zakudya zopindulitsa zomwe zimapezeka mumafuta osayengedwa zimawonongeka mafuta akatenthedwa - kuphatikiza kukoma kumatha kukhala kosasangalatsa.

Ma PUFA nthawi zambiri sakhala abwino kuphika chifukwa amadziwika kuti amawotcha mosavuta, zomwe zimawapangitsa kukhala "poizoni." Komabe, mafuta amphesa amakhala ndi utsi wokwera kwambiri kuposa mafuta a azitona ndi mafuta ena a PUFA.

Ndi utsi wa madigiri 421 Fahrenheit, ndi koyenera kuphika kutentha kwambiri, monga kuphika kapena kuphika, koma kuyaka kwambiri kumalimbikitsidwabe. Poyerekeza, mafuta a avocado ali ndi utsi wa pafupifupi madigiri 520, batala ndi mafuta a kokonati ali ndi utsi wa madigiri 350, ndipo mafuta a azitona ali ndi madigiri pafupifupi 410.
