I raro i ngā aratohu ētita tino pakari mō te whiriwhiri i ngā puna kōrero, ka hono atu mātou ki ngā whare rangahau mātauranga anake, ki ngā pāpāho rongonui, ā, ki te wātea, ki ngā rangahau hauora kua arotakehia e ngā hoa. Kia mōhio koe ko ngā tau kei roto i ngā parekete (1, 2, me ētahi atu) he hononga pāwhiri ki ēnei rangahau.
Kāore ngā kōrero o roto i ā mātou tuhinga i te whakaarohia hei whakakapi i ngā whakawhitiwhiti kōrero whaiaro me tētahi tohunga hauora whai tohu, ā, kāore hoki i te whakaarohia hei whakamahi hei tohutohu hauora.
I ahu mai tēnei tuhinga i ngā taunakitanga pūtaiao, i tuhia e ngā tohunga, ā, i arotakehia e tā mātou tīma ētita whakangungua. Kia mōhio koe, ko ngā tau kei roto i ngā pareneti (1, 2, me ētahi atu) e tohu ana i ngā hononga ka taea te pāwhiri ki ngā rangahau hauora kua arotakehia e ngā hoa.
Kei roto i tā mātou tīma ngā tohunga kai me ngā tohunga kai kua rēhitatia, ngā kaiako hauora whai tiwhikete, me ngā tohunga whakapakari tinana whai tiwhikete, ngā kaiwhakaako whaiaro me ngā tohunga whakatikatika tinana. Ehara i te mea ko te rangahau hōhonu anake te whāinga o tā mātou tīma, engari ko te kore whakaaro me te kore whakaaro tika.
Kāore ngā kōrero o roto i ā mātou tuhinga i te whakaarohia hei whakakapi i ngā whakawhitiwhiti kōrero whaiaro me tētahi tohunga hauora whai tohu, ā, kāore hoki i te whakaarohia hei whakamahi hei tohutohu hauora.
Ko tētahi o ngā tāpiringa e whakamahia whānuitia ana i roto i ngā rongoā me ngā tāpiringa i ēnei rā ko te konupora stearate. Ina hoki, ka uaua ki te kimi i tētahi tāpiringa i te mākete i ēnei rā kāore i roto—ahakoa he tāpiringa konupora, he whākōkī nakunaku, he tāpiringa kē atu rānei e pai ana ki a koe—ahakoa kāore pea koe e kite tika i tōna ingoa.
He maha ngā wā ka karangatia ki ētahi atu ingoa pērā i te "vegetable stearate" me ngā mea i ahu mai i te "stearic acid", e kitea ana i ngā wāhi katoa. Haunga tōna noho ki ngā wāhi katoa, ko te konupūmā stearate tētahi o ngā kai tino tautohetia i te ao tāpiringa.
I ētahi wā, he rite tēnei ki te tautohetohe mō te huaora B17: he paitini, he rongoā rānei mō te mate pukupuku. Engari, mō te marea, he maha ngā taunakitanga taupatupatu a ngā tohunga hauora taiao, ngā kairangahau kamupene tāpiringa, me ngā rata hei tautoko i ō rātou ake whakaaro, ā, he tino uaua ki te tiki i ngā meka.
He pai ake te whai i tētahi huarahi whai hua ki ēnei tautohetohe, ā, kia tūpato hoki kei tautoko i ngā tirohanga tino rerekē.
Ko te tino take: Pērā i te nuinga o ngā whakakī me ngā kaihoko whakapūpū, he kino te konupora stearate ki te hauora mēnā he nui ngā horopeta, engari kāore e tino kino te kai pērā i tā ētahi e kī nei nā te mea he iti noa iho ngā horopeta e wātea ana.
Ko te konupūmā stearate te tote konupūmā o te waikawa stearic. Ko te tikanga, he matū kei roto ngā momo e rua o te waikawa stearic me te konupūmā.
Ko te waikawa stearic he waikawa ngako kukū e kitea ana i roto i te maha o ngā kai, tae atu ki ngā ngako me ngā hinu kararehe me ngā huawhenua. Ko te koko me te purapura harakeke he tauira o ngā kai he nui te waikawa stearic.
I muri i te pakaru o te konupūmā stearate ki roto i te tinana, tata rite tonu te nui o te ngako ki te waikawa stearic. He mea noa te whakamahi i te paura konupūmā stearate hei tāpiringa kai, hei puna kai, hei tāpiringa hoki i roto i ngā mea whakapaipai.
Ko te konupūmā stearate te matū e whakamahia whānuitia ana i roto i te hanga papa nā te mea he hinu whakahinuhinu whai hua. Ka whakamahia hoki i roto i ngā kāpūru, paura, me te maha o ngā kai, tae atu ki te maha o ngā monamona, ngā kāmi, ngā otaota, ngā mea kakara, me ngā kai tunu.
E mōhiotia ana ko te "kaihoko rere," ka āwhina i te tere ake o te tukanga whakaputa mā te aukati i ngā kai kei piri ki ngā taputapu mīhini. He ranunga paura e kapi ana i te nuinga o ngā ranunga rongoā, tāpiringa rānei ki te iti noa o te nui.
Ka taea hoki te whakamahi hei emulsifier, hei piripiri, hei whakamātotoru, hei ārai i te whakapiripiri, hei hinu whakahinuhinu, hei tukunga me te tango huka.
Ehara i te mea he mea whai hua mō ngā mahi hanga anake mā te tuku i te kawe maeneene i runga i ngā mīhini e hanga ana i aua mea, engari ka māmā ake hoki te horomi me te neke i ngā papa i roto i te ara kai. Ko te konupora stearate tētahi atu mea whakauru noa, ko te tikanga ka āwhina i te whakarei ake i te pānga rongoā o ngā momo matū hohe rongoā, ā, ka whakatairanga i te mimiti me te whakarewa o ngā rongoā.
E kī ana ētahi ka taea e rātou te whakaputa rongoā, tāpiringa rānei, me te kore he matū tāpiri pēnei i te konupora stearate, ā, ka ara ake te pātai he aha i whakamahia ai ēnei rongoā ina wātea mai ētahi atu momo rongoā taiao. Engari, kāore pea tēnei e pono.
Ko ētahi hua kua hangaia inaianei me ngā momo whakakapi mō te konupora stearate mā te whakamahi i ngā mea tāpiri taiao pērā i te ascorbyl palmitate, engari ka mahia tēnei e mātou ina tika ana, ehara i te mea nā te mea kua hē tā mātou pūtaiao. Heoi, kāore ēnei momo whakakapi e whai hua tonu nā te mea he rerekē ngā āhuatanga ā-tinana.
Kāore i te mārama i tēnei wā mēnā ka taea, mēnā rānei e tika ana te whakakapi mō te konupora stearate.
He haumaru pea te konupūmā stearate ina kainga i roto i ngā rahinga e kitea ana i roto i ngā tāpiringa kai me ngā puna kai. Inaa, ahakoa e mōhio ana koe, kāore rānei, tera pea ka tāpirihia e koe ngā huaora maha, te hinu kokonati, ngā hua manu me te ika i ia rā.
Pērā i ētahi atu kohuke chelated (magnesium ascorbate, magnesium citrate, me ētahi atu), kāore he pānga kino o roto nā te mea he kohuke me ngā waikawa kai (waikawa stearic huawhenua kua whakakorengia ki ngā tote konupora). He matū pumau, he matū koretake hoki.
I tētahi atu taha, i roto i tā rātou pūrongo mō te konupora stearate, i whakatūpato te National Institutes of Health (NIH) ka pā kino pea te nui o te konupora ki te tuku i ngā uaua io, ā, ka ngoikore, ka heke hoki ngā uruparenga. Ahakoa he tino onge tēnei, e ai ki te National Institutes of Health (NIH):
E mano tini ngā mate e pāngia ana i ia tau, engari he onge ngā āhuatanga kino. Ko te nuinga o te wā ka puta te paitini kino i muri i te werohanga ā-uaua mō ngā hāora maha (i te nuinga o te wā i roto i te preeclampsia) ā, ka puta pea i muri i te nui rawa o te rongoā, inā koa i roto i te ngoikoretanga o te whatukuhu. Kua pūrongohia te paitini kino i muri i te horomia ohorere, engari he tino onge.
Heoi, kāore te pūrongo i whakamarie i te katoa. Mā te tirotiro poto noa i a Google ka kitea he maha ngā pānga taha o te konupūmā stearate, pēnei i:
Nā te mea he wai-whakaaro ("he pai ki te wai"), e ai ki ngā pūrongo, ka taea e te konupūmā stearate te whakaroa i te tere o te whakarewanga o ngā rongoā me ngā tāpiringa i roto i te ara kai. Ko ngā āhuatanga tiaki o te konupūmā stearate ka pā tika ki te kaha o te tinana ki te mimiti i ngā matū me ngā matūkai, ā, i roto i te ariā, ka kore e whai hua te rongoā, te tāpiringa rānei mēnā kāore e taea e te tinana te wawahi tika.
I tētahi atu taha, e ai ki tētahi rangahau i whakahaerehia e te Whare Wānanga o Maryland, kāore te konupūmā stearate e pā ki te nui o ngā matū e tukuna ana e te propranolol hydrochloride, he rongoā e whakamahia ana hei whakahaere i te tere o te ngakau me te bronchospasm, nō reira kāore anō kia whakatauhia he aha te take i tēnei wā.
Ina hoki, ka whakamahia e ngā kaihanga te konupora stearate hei whakanui ake i te matotoru o ngā kāpūru me te whakatairanga i te mimiti tika o te rongoā mā te whakaroa i te pakaru o ngā ihirangi kia tae rā anō ki ngā whekau.
Ko ngā pūtau-T, he wāhanga matua o te pūnaha ārai mate o te tinana e whakaeke ana i ngā mate pukupuku, kāore e pāngia tika e te konupora stearate, engari e te waikawa stearic, te wāhanga matua o ngā mea tāpiri noa.
I whakaahuahia tuatahitia i te tau 1990 i roto i te puka Immunology, i reira i whakaatuhia ai e tēnei rangahau nui te pehitanga o ngā urupare ārai mate e whakawhirinaki ana ki te T i te aroaro o te waikawa stearic anake.
I roto i tētahi rangahau Hapanihi e arotake ana i ngā mea tāpiri noa, i kitea ko te konupūmā stearate huawhenua te mea e tīmata ana i te hanganga formaldehyde. Heoi, kāore pea tēnei i te tino whakamataku pērā i te āhua, e whakaatu ana ngā taunakitanga he mea tūturu te formaldehyde i roto i te maha o ngā hua hou, huawhenua me ngā hua kararehe, tae atu ki ngā aporo, panana, pīnihi, kāreti, mīti kau, tae atu ki te kawhe.
Hei whakamarie i tō hinengaro, ko te konupūmā stearate te mea iti rawa o te formaldehyde o ngā whakakī katoa i whakamatautauria: 0.3 nanograms mō ia karamu o te konupūmā stearate. Hei whakataurite, ko te kai i ngā harore shiitake maroke ka nui ake i te 406 milligrams o te formaldehyde mō ia kirokaramu ka kainga.
I te tau 2011, i whakaputa te World Health Organization i tētahi pūrongo e whakaahua ana i te poke o ētahi puranga konupora stearate ki ngā matū kino pea, tae atu ki te bisphenol A, te konupūmā hauwaiwai, te dibenzoylmethane, te irganox 1010 me te zeolite (te konutai konumohe silicate).
Nā te mea he āhuatanga takitahi tēnei, kāore e taea e tātou te whakatau wawe me tūpato te hunga e tango ana i ngā tāpiringa me ngā rongoā kei roto ko te konupora stearate ki ngā poke paitini.
Tērā pea ka pāngia ētahi tāngata e ngā tohumate mate pāwera i muri i te kai i ngā hua, i ngā tāpiringa rānei kei roto ko te konupora stearate, ka pā mai pea te mate korere me te mamae o te puku. Mena ka pā mai he pānga kino ki ngā tāpiringa, me pānui marie koe i ngā tapanga kai, me te mahi rangahau iti kia kitea ai ngā hua kāore i hangaia ki ngā tāpiringa rongonui.
E taunaki ana te National Center for Biotechnology kia kiia he haumaru te horopeta o te 2500 mg o te konupora stearate mō ia kirokaramu o te taumaha tinana. Mō te pakeke e 150 pauna te taumaha, he rite tēnei ki te 170,000 mirikaramu ia rā.
Ina whakaarohia ngā pānga kino pea o te konupora stearate, he mea pai kia whakaarohia te "whakawhirinakitanga horopeta". Arā, haunga te nui rawa o te konupora stearate i roto i te uaua mō ngā mate kino, ko te kino o te konupora stearate kua whakaaturia noa i roto i ngā rangahau taiwhanga i reira i whāngaihia ai ngā kiore ki te nui rawa o te konupora stearate, ā, kāore i taea e te tangata o te ao te kai i taua nui.
I te tau 1980, i whakaputaina e te puka Toxicology ngā hua o tētahi rangahau i whāngaihia ai ngā kiore 40 ki te kai haurua-hangai kei roto ko te 0%, 5%, 10%, 20% rānei te konupūmā stearate mō ngā marama e toru. Anei āna i kitea:
Me mōhio he iti noa te nui o te waikawa stearic me te konupūmā stearate e whakamahia whānuitia ana i roto i ngā papa. Ko te waikawa stearic te nuinga o te wā e hanga ana i te 0.5–10% o te taumaha o te papa, ko te konupūmā stearate ia e hanga ana i te 0.25–1.5% o te taumaha o te papa. Nō reira, ko te papa 500 mg pea kei roto i te 25 mg o te waikawa stearic me te 5 mg o te konupūmā stearate.
Ka pā kino te nui rawa o te wai ki te tangata, ā, ka mate pea ia i te nui rawa o te wai e inumia ana, tika? He mea nui tēnei kia maumahara, nā te mea, kia kore ai e pā kino te konupora stearate ki tētahi, me tango e rātou ngā mano tini o ngā kāpūre/papa i ia rā.
