Ko te ketosis he āhua pākia e tahuna ai e te tinana te ngako kua rongoatia hei pūngao, ā, kei te piki haere te rongonui i ēnei rā. He maha ngā tikanga e whakamahia ana e te tangata hei whakatutuki me te pupuri i tēnei āhua, tae atu ki te whai i te kai ketogenic, te nohopuku me te tango i ngā tāpiringa. I roto i ēnei tāpiringa, ko ngā ketone esters me ngā ketone salts ngā kōwhiringa rongonui e rua. Me ako atu tātou mō ngā ketone esters me ō rātou rerekētanga mai i ngā ketone salts, me pēhea?
Hei mōhio ki ngā ketone esters, me mārama tuatahi tātou ki ngā ketones. Ko ngā ketones he puranga wahie e hangaia ana e te tinana ina tahuna te ngako, nō reira he aha ngā ketone esters? Ko ngā ketone esters he tinana ketone exogenous e whakatairanga ana i te ketosis i roto i te tinana. Ina kei roto te tinana i te āhua ketosis, ka wahia e te ate te ngako hei tinana ketone whai pūngao, ka whakakahangia ngā pūtau mā roto i te toto. I roto i ā tātou kai, ka whakamahia e ā tātou pūtau te hukahuka hei pūngao, ko te hukahuka hoki te pūtake matua o te pūngao o te tinana, engari i te korenga o te hukahuka, ka hangaia e te tinana ngā ketones mā roto i te tukanga e kiia nei ko te ketogenesis. He pūtake pūngao pai ake ngā tinana ketone i te hukahuka, ā, kua whakaatuhia he maha ngā painga hauora.
E rua ngā wāhanga matua o ngā tinana ketone o waho, arā, ko ngā ketone esters me ngā tote ketone. Ko ngā ketone esters, e mōhiotia ana ko ngā ketone monoesters, he matū e whakanui ana i te nui o ngā ketone i roto i te toto. He ketone o waho tēnei e hangaia ana mā te tāpiri i te tinana ketone ki te ngota waipiro. Mā tēnei tukanga ka tino wātea ki te tinana, ko te tikanga ka tere te mimiti, ā, ka tere te whakapiki i ngā taumata ketone i roto i te toto. Ko ngā tote ketone he paura kei roto ko te BHB e herea ana ki ngā tote kohuke (te nuinga ko te konutai, te pāhare pākawa, te konupūmā rānei) ngā waikawa amino rānei (pērā i te lysine, te arginine rānei), ko te tote ketone tino noa ko te β-hydroxybutyrate (BHB) e herea ana ki te konutai, engari kei te wātea hoki ētahi atu tote pāhare pākawa me te konupora. Ka taea e ngā tote ketone te whakanui ake i ngā taumata toto o te isoform BHB o te l-β-hydroxybutyrate (l-BHB).
Nā te mea he ketone exogenous ngā ketone esters me ngā tote ketone, ko te tikanga ka hangaia i roto i te vitro. Ka taea e rātou te whakanui ake i ngā taumata ketone toto, te whakarato pūngao, me te whakapai ake i te mahi hinengaro. Ka taea hoki e rātou te āwhina i a koe ki te tomo ki te āhua ketotic tere ake me te pupuri i taua āhua mō te wā roa. Mō ngā taumata ketone toto, ko ngā ketone esters he wai BHB kore tote, kāore he wāhanga tāpiri. Kāore rātou e herea ki ngā kohuke pēnei i ngā tote BHB, engari ki ngā matūmua ketone (pērā i te butanediol, te glycerol rānei) mā roto i ngā here ester, ā, ka taea e ngā ketone esters te whakarei ake i te d-β-. He tere ake, he nui ake te pānga o ngā ketone esters ki ngā taumata toto o te momo BHB o te waikawa hydroxybutyric (d-BHB) ki ngā tote ketone.
1. Te whakapai ake i te mahi hākinakina
Ko tētahi o ngā painga nui o ngā ketone esters ko tōna kaha ki te whakarei ake i te mahi hākinakina. Nā te mea he puna pūngao pai ake ngā ketone i te kurukose, koinei te puna pūngao matua o te tinana. I roto i ngā mahi whakakori tinana kaha, ka whakawhirinaki te tinana ki te kurukose hei whakaputa pūngao, engari ka tere te pau o te kurukose iti o te tinana, ka arahi ki te ngenge me te heke o te mahi. Ka whakaratohia e ngā ketone esters he puna pūngao kua rite, ka māmā ake te pana a ngā kaitākaro i a rātou anō ki ō rātou rohe me te kore e ngenge e puta ana ina whakawhirinaki ki te kurukose anake.
2. Whakapai ake i te mahi a te roro
Ko tētahi atu painga whakamiharo o ngā ketone esters ko tōna kaha ki te whakapai ake i te mahi a te roro. He okana nui te kaha o te roro e hiahia ana ki te tuku tonu i te hukahuka kia pai ai te mahi. Heoi, he puna kaha hoki ngā ketone mō te roro, ā, kua whakaatuhia e ngā rangahau ina whakakahangia te roro e ngā ketone, ka taea e ia te mahi pai ake i te wā e whakawhirinaki ana ki te hukahuka anake. Koinei te take kua whakaatuhia ai ka whakapai ake ngā ketone esters i te mahi hinengaro, te mahara me te aro, ka waiho hei whiringa pai mō te hunga e hiahia ana ki te whakarei ake i te mahi a te roro.
3. Whakarei ake i te whakaheke taumaha
Hei whakamutunga, ka āwhina hoki ngā ketone esters ki te whakaiti i te taumaha. Ina kei roto te tinana i te āhua ketosis (arā, ina whakakahangia e ngā ketones), ka tahuna te ngako he pai ake i te hukahuka hei pūngao. Ko te tikanga o tēnei he nui ake te tūponotanga o te tinana ki te tahu i ngā pūtau ngako kua rongoatia hei wahie, ka hua ake ai te whakahekenga taumaha. Hei tāpiri, ka āwhina pea ngā ketones ki te whakaiti i te hiahia kai, ka māmā ake ai te piri ki tētahi kai iti-kaora me te whakaiti i te taumaha he pai ake.
● Hei mōhio mēnā ka taea e ngā ketone esters te āwhina i te whakaiti i te taumaha, me mārama tuatahi tātou he aha ngā ketone esters. Ko ngā ketone esters he matū hangai kei roto ngā ketone ka ngawari te mimiti e te tinana tangata, ka waiho hei puna wahie whai hua ake. Ina noho tātou i roto i te āhua ketotic, ko ngā ketone he puna pūngao e whakaputaina ana e tō tātou tinana. Ka puta tēnei tukanga ina iti te ihirangi huka i roto i te toto, ā, ka tīmata te tinana ki te wawahi i te ngako kua rongoatia hei hanga ketone hei whakarato pūngao.
● Kua whakaatuhia e ngā kairangahau kua pai ake te manawanui o ngā kaitākaro e tango ana i ngā Ketone esters hei tāpiringa i te wā e whakakorikori tinana ana. I kitea i roto i tētahi rangahau tata nei ka taea e ngā ketone esters te whakapai ake i te mahi a ngā kaieke pahikara rangatira mā te 2%. Engari he tikanga tēnei ka ngaro te taumaha mō te hunga noa? Ko te whakautu pea. Kua whakaatuhia e ngā rangahau ka taea e ngā ketone esters te aukati i te hiahia kai, ka heke te kai karori me te hekenga pea o te taumaha. Heoi, me whai rangahau anō kia mōhio ai mēnā he rawaka tēnei pānga hei pā ki te pānga whakaheke taumaha whānui.
●Hei tāpiritanga, ka taea hoki e ngā ketone esters te whakanui ake i te hanga o tētahi homoni e kiia nei ko te leptin. He mahi nui tā te leptin ki te whakahaere i te hiahia kai, te pākia o te kai, me te whakapaunga pūngao. Mā te nui ake o te leptin i roto i te tinana ka taea te whakaiti i te hiahia kai me te āwhina ki te whakaiti i te kai katoa.
● Haunga te pehi i te hiahia kai, mā te whakamahi i ngā ketone esters ka piki ake te kaha me te tere o te pākia o te tinana. Ka hua ake tēnei i te nui ake o te kai karori me te whakamahinga whai hua ake o te ngako kua rongoatia hei whiwhi kaha. Mā tēnei, me te kaha ki te pehi i te hiahia kai, ka āwhina i te whakaputa i te korenga o ngā karori e tika ana mō te whakaheke taumaha.
●Heoi, me maumahara ehara ngā ketone esters i te rongoā mō te whakaiti taumaha. Ko te kai hauora me te whakakori tinana auau tonu ngā huarahi tino whai hua ki te whakaiti taumaha. Ka taea anake te whakamahi i ngā ketone esters hei tāpiringa, ehara i te mea koinei anake te huarahi ki te whakaiti taumaha.
●Hei whakarāpopototanga, tera pea he painga pea o ngā ketone esters mō te whakaheke taumaha, engari me rangahau tonu te whai huatanga o ēnei. Ka taea e rātou te āwhina ki te pehi i te hiahia kai, te whakaputa i te kore rawa o ngā kaora, me te whakanui ake i ngā taumata pūngao, engari me whakamahi me te tupato, kaua ko te huarahi anake hei whakaheke taumaha. Ko te kai hauora, te whakakori tinana auau, me te noho taurite tonu ngā huarahi tino whai hua ki te whakatutuki me te pupuri i te taumaha hauora.
Kei te wātea te ketone ester i roto i te āhua wai, ā, ka taea te tango ā-waha. Heoi, i te wā e whakamahi ana i te ketone ester, he mea nui kia whai i ngā tohutohu horopeta a ngā tohunga. Ko te tikanga kia tīmata me te horopeta iti, kātahi ka piki haere te horopeta kia tae rā anō ki te pānga e hiahiatia ana.
He mea nui anō hoki kia mōhiotia ko ngā ketone esters me whakamahi tahi me te kai ketogenic kia tutuki ai ngā hua tino pai. Ko te kai ketogenic he kai nui te ngako, he pūmua-taurite, he iti te warowaihā e whakanoho ana i te tinana ki te āhua o te ketosis.
