Ingabe ufuna ukugcina ingqondo yakho ibukhali njengoba ukhula? Yakha inqwaba emisipha yakho futhi unake okhalweni lwakho. Ngokokuqala ngqa, ososayensi bathole ukuthi ukuba nemisipha encane kanye namafutha amaningi emzimbeni kungase kuthinte ukucabanga kwethu njengoba sikhula, futhi izinguquko ezingxenyeni zamasosha omzimba zingase zibe nesibopho, ngokocwaningo olwenziwa abacwaningi base-Iowa State.
Ucwaningo, olwanyatheliswa ku-Brain, Behavior and Immunity, luhlaziye idatha yeminyaka eyisithupha evela kwabesilisa nabesifazane abangu-4.431, abaneminyaka yobudala engama-64. Abacwaningi bahlola izinguquko zabahlanganyeli ku isisindo esincane namafutha omzimba isisu kanye nengqikithi, nokuthi lezo zinguquko ekubunjweni komzimba zazihlobene kanjani nezinguquko zobuhlakani obuwuketshezi (noma amakhono anengqondo okuxazulula izinkinga) phakathi nenkathi yocwaningo.
Ikhuluphele kangakanani ihlakaniphe kancane?
Bathole ukuthi abantu abaneminyaka engu-40 no-50 ababenayo inani elikhulu lamafutha phakathi nendawo, lalinobuhlakani obubi kakhulu uketshezi njengoba bekhula. Ngakolunye uhlangothi, ukuba nenqwaba yemisipha, kwakuxhunyaniswa nokuhlakanipha koketshezi olungcono. Ukwakheka komzimba-isixhumanisi samandla obuchopho esiphethwe kungakhathaliseki ubudala nemfundo.
«Iminyaka yobudala yokulandelana kwezikhathi ayibonakali iyimbangela yokwehla kobuhlakani boketshezi ngokuhamba kwesikhathi.kusho umbhali wocwaningo u-Auriel Willette esitatimendeni sabezindaba. «Kubonakala sengathi iminyaka yezinto eziphilayo, okuyinto lapha inani lamafutha nemisipha".
Lokhu kuxhumana okubonakala kungenakwenzeka kokwakheka kobuchopho nomzimba kubonakala kusekelwe kukho ukuthi amafutha omzimba awathinta kanjani amasosha omzimba. Ucwaningo lwangaphambilini lubonise ukuthi abantu abane-body mass index (BMI) banamazinga aphezulu okusebenza kwamasosha omzimba egazini labo, okuvusa amasosha omzimba ebuchosheni futhi aphazamise ukuqonda.
Ukweqa lokho okutholakele, abacwaningi kulolu cwaningo babheka amafutha omzimba nemisipha ngokuhlukana (njengoba i-BMI ithatha kuphela isisindo somzimba esiphelele). Futhi bathola ukuxhumana okucacile phakathi kwamafutha omzimba nokwanda komsebenzi wokuzivikela komzimba. Kwabesifazane abakulolu cwaningo, sonke isixhumanisi phakathi kokwanda kwamafutha esisu kanye nokuhlakanipha koketshezi olumpofu kwachazwa izinguquko ezinhlotsheni ezimbili zamangqamuzana egazi amhlophe: ama-lymphocyte nama-eosinophils. Emadodeni, uhlobo oluhluke ngokuphelele lwengqamuzana elimhlophe legazi, i ama-basophils, yachaza cishe ingxenye yobudlelwano bobuhlakani phakathi kwamafutha noketshezi.
Ukuba nemisipha eyengeziwe kwakuhlotshaniswa nokuhlakanipha okungcono koketshezi, kodwa kwakungekho ukuxhumana okuqinile kwesimiso sokuzivikela komzimba.
«Kuzodingeka ucwaningo olwengeziwe ukuze kubonakale ukuthi abantu abanemisipha encane kanye nenqwaba yamafutha bangase babe nesifo i-Alzheimer's, futhi iyini indima yamasosha omzimba?".
Phakathi naleso sikhathi, ukuvikela ingqondo yakho kungesinye isizathu sokudla ukudla okunempilo futhi ushaye ijimu ukuze wakhe imisipha.
