A1 vs. A2 Lebese - Na ke Habohlokoa?

Litaba

• Mantsoe ana a bolelang?
• Litlhaloso tse mpe ka protheine ea A1
• Mofuta oa 1 oa lefu la tsoekere
• Lefu la pelo
• Lefu la masea la lefu la tšohanyetso
• Autism
• Bophelo bo botle ba ho siloa
• Ntlha ea bohlokoa

Litholoana tsa lebese li ka itšetleha ka mofuta oa khomo eo e tsoang ho eona.

Hajoale, lebese la A2 le rekisoa e le khetho e nepahetseng ho feta lebese le tloaelehileng la A1.

Baloaneli ba tiisa hore A2 e na le melemo e 'maloa ea bophelo bo botle' me ho bonolo ho batho ba nang le mamello ea lebese ho e sila.

Sengoloa sena se shebile mahlale ka mora lebese la A1 le A2.

Mantsoe ana a bolelang?

Casein ke sehlopha se seholo ka ho fetisisa sa liprotheine tse ka lebeseng, tse etsang 80% ea liprotheine kaofela.

Ho na le mefuta e 'maloa ea casin ka lebeseng. Beta-casein ke ea bobeli e atileng haholo 'me e fumaneha ka mefuta e 13 e fapaneng ().

Mefuta e 'meli e tloaelehileng ke:

• A1 beta-casein. Lebese le tsoang mefuteng ea likhomo tse tsoang leboea ho Europe hangata le phahame ho A1 beta-casein. Mefuta ena e kenyelletsa Holstein, Friesian, Ayrshire le British Shorthorn.
• A2 beta-casein. Lebese le phahameng ho A2 beta-casein le fumaneha haholo mefuteng e qalileng lihlekehlekeng tsa Channel le boroa ho Fora. Tsena li kenyelletsa likhomo tsa Guernsey, Jersey, Charolais le Limousin (,).

Lebese le tloaelehileng le na le A1 le A2 beta-casein, empa lebese la A2 le na le A2 beta-casein feela.

Liphuputso tse ling li bontša hore A1 beta-casein e ka ba kotsi le hore A2 beta-casein ke khetho e sireletsehileng.

Kahoo, ho na le ngangisano ea sechaba le ea mahlale mabapi le mefuta ena e 'meli ea lebese.

Lebese la A2 le hlahisoa le ho rekisoa ke A2 Milk Company mme ha le na A1 beta-casein.

Lebese la A1 le A2 le na le mefuta e fapaneng ea protheine ea beta-casein. Boithuto bo bong bo bontša hore lebese la A2 e kanna ea ba bophelo bo botle ba tse peli.

Litlhaloso tse mpe ka protheine ea A1

Beta-casomorphin-7 (BCM-7) ke peptide ea opioid e ntšitsoeng nakong ea tšilo ea A1 beta-casein (, 4).

Ke lona lebaka leo batho ba bang ba lumelang hore lebese le tloaelehileng le se na bophelo bo botle ho feta lebese la A2.

Lihlopha tse 'maloa tsa lipatlisiso li fana ka maikutlo a hore BCM-7 e kanna ea amahanngoa le lefu la tsoekere la mofuta oa 1, lefu la pelo, lefu la masea, autism le mathata a tšilo ea lijo (,,,).

Le ha BCM-7 e ka ama tsamaiso ea hau ea tšilo ea lijo, ho ntse ho sa hlaka hore na BCM-7 e kenelletse joang maling a hau.

Boithuto ha bo so fumane BCM-7 maling a batho ba baholo ba phetseng hantle ba noang lebese la khomo, empa liteko tse 'maloa li supa hore BCM-7 e kanna ea ba teng ho masea (,,).

Le ha BCM-7 e entsoe lipatlisiso tse batsi, litlamorao tsa bophelo bo botle li lula li sa hlaka.

Mofuta oa 1 oa lefu la tsoekere

Mofuta oa 1 oa lefu la tsoekere o fumanoa ho bana mme o tšoauoa ka khaello ea insulin.

Liphuputso tse 'maloa li bontša hore ho noa lebese la A1 nakong ea bongoana ho eketsa menyetla ea ho ba le lefu la tsoekere la mofuta oa 1 (,,,).

Leha ho le joalo, lithuto tsena li shebile. Ba ke ke ba paka hore A1 beta-casein e baka lefu la tsoekere la mofuta oa 1 - feela hore ba e fumanang ba kotsing e kholo.

Le ha lithuto tse ling tsa liphoofolo li sa fumane phapang lipakeng tsa A1 le A2 beta-casein, tse ling li bonts'a A1 beta-casein ho ba le litlamorao tse mpe ho mofuta oa 1 lefu la tsoekere (,,,).

Ho fihlela joale, ha ho liteko tsa bongaka ho batho tse entseng lipatlisiso ka phello ea A1 beta-casein ho mofuta oa 1 oa lefu la tsoekere.

Lefu la pelo

Lithuto tse peli tsa ho shebella li amahanya tšebeliso ea lebese la A1 le kotsi e eketsehileng ea lefu la pelo (,).

Teko e le 'ngoe ea mebutlanyana e bontšitse hore A1 beta-casein e khothalletsa ho aha mafura methapong ea mali e lemetseng. Moralo ona o ne o le tlase haholo ha mebutlanyana e ne e ja A2 beta-casein ().

Ho bokella mafura ho ka koala methapo ea mali mme ha baka lefu la pelo. Ho ntse ho le joalo, ho phehiloe khang ka bohlokoa ba batho ba liphetho.

Ho fihlela joale, liteko tse peli li batlisitse litlamorao tsa lebese la A1 ho lisosa tsa kotsi ea lefu la pelo ho batho (,).

Phuputsong e le 'ngoe ho batho ba baholo ba 15 ba kotsing e kholo ea lefu la pelo, ha ho litlamorao tse mpe tse ileng tsa bonoa. A1 le A2 li bile le litlamorao tse tšoanang ts'ebetsong ea methapo ea mali, khatello ea mali, mafura a mali le matšoao a ho ruruha ().

Phuputso e 'ngoe ha ea ka ea fumana phapang e kholo liphellong tsa A1 le A2 casein ho cholesterol ea mali ().

Lefu la masea la lefu la tšohanyetso

Lefu la tšohanyetso la lefu la masea (SIDS) ke lona sesosa se tloaelehileng sa lefu ho masea a ka tlase ho likhoeli tse 12.

SIDS ke lefu le sa lebelloang la lesea ntle le lebaka ().

Bafuputsi ba bang ba nahanne hore BCM-7 e kanna ea ameha maemong a mang a SIDS ().

Phuputso e 'ngoe e fumane maemo a phahameng a BCM-7 maling a masea a emisitseng nakoana ho hema nakong ea boroko. Boemo bona, bo tsejoang e le ho koaleha moea ka nakoana borokong, bo amana le kotsi e eketsehileng ea SIDS ().

Liphetho tsena li supa hore bana ba bang ba kanna ba ela hloko A1 beta-casein e fumanoang lebeseng la khomo. Empa, lithuto tse ling lia hlokahala pele ho ka fihleloa liqeto tse tiileng.

Autism

Autism ke boemo ba kelello bo khetholloang ke ho se sebelisane hantle sechabeng le boits'oaro bo pheta-phetoang.

Ka khopolo, li-peptide tse kang BCM-7 li ka bapala karolo ho nts'etsopele ea autism. Leha ho le joalo, lithuto ha li tšehetse mekhoa eohle e reriloeng (,,).

Phuputso e 'ngoe ho masea e fumane litekanyo tse phahameng tsa BCM-7 ho lebese la khomo le fepiloeng ha le bapisoa le ba anyesitsoeng. Ka ho hlakileng, maemo a BCM-7 a theohile ka potlako ho masea a mang ha a ntse a lula holimo ho a mang.

Bakeng sa ba bolokileng maemo ana a phahameng, BCM-7 e ne e amahanngoa le matla a ho holofala a ho rala le ho etsa liketso ().

Phuputso e 'ngoe e bonts'a hore ho noa lebese la khomo ho ka mpefatsa matšoao a boits'oaro ho bana ba nang le autism. Empa lithuto tse ling ha lia ka tsa fumana litlamorao ho boitšoaro (,,).

Ho fihlela hajoale, ha ho liteko tsa motho tse batlisitseng ka kotloloho litlamorao tsa lebese la A1 le A2 matšoao a autism.

Liphuputso tse 'maloa li bontša hore A1 beta-casein le peptide BCM-7 li kanna tsa amahanngoa le lefu la tsoekere, lefu la pelo, autism le SIDS. Le ha ho le joalo, liphetho li tsoakane ebile ho hlokahala lipatlisiso tse ling.

Bophelo bo botle ba ho siloa

Ho hloka mamello ea Lactose ke ho se khone ho cheka tsoekere ea lebese ka botlalo (lactose). Sena ke sesosa se tloaelehileng sa ho ruruha, khase le lets'ollo.

Palo ea lactose lebese la A1 le A2 ea tšoana. Leha ho le joalo, batho ba bang ba na le maikutlo a hore lebese la A2 le baka ho ruruha hanyane ho feta lebese la A1.

Ebile, liphuputso li bonts'a hore likarolo tsa lebese ntle le lactose li ka baka mathata a silang lijo (,).

Bo-rasaense ba hlahisitse hore liprotheine tse itseng tsa lebese li kanna tsa ikarabella ho mamellaneng ha batho ba bang lebese.

Phuputso e 'ngoe ho batho ba 41 e bontšitse hore lebese la A1 le baka litulo tse bonojoana ho feta lebese la A2 ho batho ba bang, ha phuputso e' ngoe ho batho ba baholo ba China e fumane hore lebese la A2 le lebisitse khathatsong e tlase ea tšilo ea lijo kamora lijo (,).

Ntle le moo, lithuto tsa liphoofolo le tsa batho li fana ka maikutlo a hore A1 beta-casein e ka eketsa ho ruruha tsamaisong ea tšilo ea lijo (,,).

Bopaki bo ntseng bo hola bo fana ka maikutlo a hore A1 beta-casein e baka matšoao a mabe a ho sila lijo ho batho ba bang.

Ntlha ea bohlokoa

Ngangisano ka litlamorao tse ka bang teng tsa bophelo bo botle ba lebese la A1 le A2 e ntse e tsoela pele.

Patlisiso e fana ka maikutlo a hore A1 beta-casein e baka matšoao a mabe a ho sila lijo ho batho ba itseng.

Empa bopaki bo ntse bo fokola haholo hore ho ka etsoa liqeto tse tiileng mabapi le likhokahanyo tse pakeng tsa A1 beta-casein le maemo a mang, joalo ka mofuta oa 1 lefu la tsoekere le autism.

Seo se boletse hore lebese la A2 le ka ba molemo haeba u ka thatafalloa ho cheka lebese le tloaelehileng.
