Hutano mhedzisiro yemukaka inogona kuvimba nerudzi rwemombe yawabva.

Parizvino, mukaka weA2 unotengeswa sesarudzo ine hutano pane mukaka wenguva dzose weA1.

Vanotsigira vanoti A2 ine zvakanakira hutano uye zviri nyore kune vanhu vane kusagadzikana kwemukaka kugaya.

Ichi chinyorwa chinotora chinangwa kutarisa sainzi iri kumashure kweA1 uye A2 mukaka.

Zvinorevei mazwi aya?

Casein ndiro rakakura boka remapuroteni mumukaka, anoumba angangoita 80% yehuwandu hwepuroteni zvirimo.

Kune mhando dzinoverengeka dzecasin mumukaka. Beta-casein ndiyo yechipiri yakanyanya kuwanda uye inowanikwa mune angangoita gumi nematanhatu mafomu ().

Mafomu maviri akajairika ndeaya:

• A1 beta-casein. Mukaka kubva kumhando dzenzombe dzakatangira kuchamhembe kweEurope inowanzo kuve yakakwira muA1 beta-casein. Mhando idzi dzinosanganisira Holstein, Friesian, Ayrshire, uye British Shorthorn.
• A2 beta-casein. Mukaka wakakwira muA2 beta-casein unonyanya kuwanikwa mumhando dzakatangira kuChannel Islands nekumaodzanyemba kweFrance. Izvi zvinosanganisira Guernsey, Jersey, Charolais, uye Limousin mombe (,).

Wenguva dzose mukaka une zvese A1 uye A2 beta-casein, asi mukaka weA2 unongova neA2 beta-casein chete.

Zvimwe zvidzidzo zvinoratidza kuti A1 beta-casein inogona kukuvadza uye kuti A2 beta-casein isarudzo yakachengeteka.

Nekudaro, pane kumwe kupokana neruzhinji uye kwesainzi pamusoro pemhando mbiri idzi dzemukaka.

Mukaka weA2 unogadzirwa nekutengeswa neA2 Milk Company uye hauna A1 beta-casein.

A1 uye A2 mukaka une mhando dzakasiyana dze beta-casein protein. Zvimwe zvidzidzo zvinoratidza kuti mukaka weA2 unogona kunge uine hutano hwevaviri.

Zvinopesana zvinotaurwa nezve A1 protein

Beta-casomorphin-7 (BCM-7) iopioid peptide yakaburitswa panguva yekugaya kweA1 beta-casein (, 4).

Ndicho chikonzero nei vamwe vanhu vachitenda kuti mukaka wenguva dzose kuve usina hutano kupfuura mukaka weA2.

Mapoka mashoma ekutsvagisa anoratidza kuti BCM-7 inogona kunge yakabatana nechirwere cheshuga 1, chirwere chemwoyo, kufa kwevacheche, autism, uye matambudziko ekugaya (,,,).

Ipo BCM-7 ingangokanganisa gadziriro yako yekugaya, ichiri kusanzwisisika kuti BCM-7 inowirwa sei muropa rako.

Dzidzo hadzina kuwana BCM-7 muropa revakuru vane hutano vanonwa mukaka wemombe, asi bvunzo shoma dzinoratidza kuti BCM-7 inogona kunge iripo kuvacheche (,,).

Ipo BCM-7 yakave yakatsvakurudzwa zvakanyanya, hutano hwayo hwese hunoramba husina kujeka.

Tora 1 chirwere cheshuga

Tora 1 chirwere cheshuga chinowanzoonekwa muvana uye chinoonekwa nekushaikwa kwe insulin.

Ongororo dzinoverengeka dzinoratidza kuti kunwa mukaka weA1 panguva yehucheche kunowedzera njodzi yako yerudzi rwe1 chirwere cheshuga (,,,).

Zvisinei, izvi zvidzidzo zvinotarisa. Ivo havagone kuratidza kuti A1 beta-casein inokonzeresa mhando 1 chirwere cheshuga - chete kuti avo vari kuwana yakawanda yacho vari panjodzi huru.

Nepo zvimwe zvidzidzo zvemhuka zvisina kuwana mutsauko pakati peA1 neA2 beta-casein, vamwe vanoratidza A1 beta-casein kuve nemidziviriro kana migumisiro yakaipa parudzi rwe1 chirwere cheshuga (,,,).

Parizvino, hapana kiriniki miedzo muvanhu yakatsvaga mhedzisiro yeA1 beta-casein parudzi rwe1 chirwere cheshuga.

Chirwere chemoyo

Zvidzidzo zviviri zvekucherechedza zvinobatanidza mukaka weA1 wemukaka kune imwe njodzi yehosha yemwoyo (,).

Imwe bvunzo yetsuro yakaratidza kuti A1 beta-casein yakasimudzira kuwanda kwemafuta mumidziyo yeropa yakakuvara. Iyi buildup yaive yakadzikira zvakanyanya apo tsuro dzakadya A2 beta-casein ().

Kuunganidzwa kwemafuta kunogona kuvhara mitsipa yeropa uye kukonzera chirwere chemwoyo. Zvakadaro, kukosha kwevanhu kwemhedzisiro kwakurukurwa ().

Parizvino, miedzo miviri yakaongorora mhedzisiro yemukaka weA1 pane chirwere chemoyo chinokonzera njodzi muvanhu (,).

Mune kumwe kuongorora muvanhu vakuru gumi nevashanu vari panjodzi huru yechirwere chemoyo, hapana chakakomba mhedzisiro yakaonekwa. A1 uye A2 yaive nemhedzisiro yakafanana neropa rekuita basa, kuwedzerwa kweropa, mafuta eropa, uye anogumbura mamaki ().

Chimwe chidzidzo hachina kuwana mutsauko wakakura mumhedzisiro yeA1 uye A2 kasino muropa cholesterol ().

Pakarepo mucheche kufa chirwere

Kamwe kamwe kacheche kufa syndrome (SIDS) ndiyo inonyanya kukonzera rufu muvacheche vari pasi pemwedzi gumi nemaviri.

SIDS kufa kusingatarisirwi kwemucheche pasina chikonzero chiri pachena ().

Vamwe vaongorori vakafungidzira kuti BCM-7 inogona kuve yakabatanidzwa mune dzimwe nguva dzeSIDS ().

Imwe ongororo yakawana yakakwira huwandu hweBMM-7 muropa revacheche vakambomira kufema panguva yekurara. Ichi chiitiko, chinozivikanwa sehope yekurara, chakabatana neyakawedzera njodzi yeSIDS ().

Mhedzisiro iyi inoratidza kuti vamwe vana vanogona kuve nehanya neA1 beta-casein inowanikwa mumukaka wemombe. Asi, zvimwe zvidzidzo zvinodiwa pasati pasvika mhedziso dzakasimba.

Autism

Autism mamiriro epfungwa anoonekwa nehurombo hwehukama kudyidzana uye kudzokorora maitiro.

Mune dzidziso, peptides senge BCM-7 inogona kutora chinzvimbo mukusimudzira kweatism. Nekudaro, zvidzidzo hazvitsigire dzese nzira dzakarongwa (,,).

Imwe ongororo muvacheche yakawana mazinga akakwirisa eBMM-7 mune ayo mukaka wemombe wakapihwa uchienzaniswa neavo vakayamwa. Sezvineiwo, mazinga eBMM-7 akadonha nekukurumidza mune vamwe vacheche vachiramba vakakwira mune vamwe.

Kune avo vakachengeta aya akakwirira mazinga, BCM-7 yaive yakabatana zvakanyanya nehurema hwekugona kuronga nekuita zviito ().

Chimwe chidzidzo chinoratidza kuti kunwa mukaka wemombe kunogona kukuvadza zviratidzo zvehunhu muvana vane autism. Asi zvimwe zvidzidzo hazvina kuwana zvinokanganisa maitiro (,,).

Parizvino, hapana kuyedzwa kwevanhu kwakanyatsoongorora mhedzisiro yeA1 uye A2 mukaka pane zviratidzo zve autism.

Zvidzidzo zvishoma zvinoratidza kuti A1 beta-casein uye peptide BCM-7 inogona kunge yakabatana nechirwere cheshuga, chirwere chemwoyo, autism, uye SIDS. Zvakadaro, mhedzisiro inosanganiswa uye kumwe kutsvagurudza kunodiwa.

Kugaya kudya

Kusagadzikana kweLactose kusakwanisa kunyatso nyura mukaka shuga (lactose). Ichi ndicho chikonzero chinowanzoitika chekuputika, gasi, uye diarrhea.

Huwandu hwerakisi mumukaka weA1 neA2 hwakaenzana. Zvisinei, vamwe vanhu vanonzwa kuti mukaka weA2 unokonzeresa kuzvimba kudarika mukaka weA1.

Muchokwadi, ongororo dzinoratidza kuti zvinhu zvemukaka kunze kweiyo lactose zvinogona kukonzera kusagadzikana kwekugaya (,).

Masayendisiti akataura kuti mamwe mapuroteni emukaka anogona kunge ari kukonzera kusagadzikana kwemukaka kwevamwe vanhu.

Imwe ongororo muvanhu makumi mana neimwe yakaratidza kuti mukaka weA1 unokonzera zvituru zvakapfava pane mukaka weA2 kune vamwe vanhu, nepo kumwe kuongorora muvakuru veChinese vakawana kuti mukaka weA2 wakakonzera kusagadzikana kwekugaya zvakanyanya mushure mekudya (,).

Pamusoro pezvo, zvidzidzo zvemhuka uye zvevanhu zvinoratidza kuti A1 beta-casein inogona kuwedzera kuzvimba mudumbu (,,).

Uchapupu huri kukura hunoratidza kuti A1 beta-casein inokonzeresa kusagadzikana kwekugaya zviratidzo mune vamwe vanhu.

Chinokosha

Gakava nezve izvo zvinogona kuve zvehutano mhedzisiro yeA1 uye A2 mukaka zviri kuenderera.

Kutsvagurudza kunoratidza kuti A1 beta-casein inokonzeresa kusagadzikana kwekugaya zviratidzo kune vamwe vanhu.

Asi humbowo huchiri husina kusimba kuti chero mhedziso dzakasimba dziitwe nezve izvo zvinofungidzirwa kubatana pakati peA1 beta-casein nemimwe mamiriro, senge rudzi rwe1 chirwere cheshuga uye autism.

Izvo zvakati, mukaka weA2 unogona kuve wakakodzera kuyedza kana uchinetseka kugaya mukaka wenguva dzose.
