Sekuyisikhathi eside odokotela bethola ukuthi itiye eliluhlaza - esinye seziphuzo ezithandwa kakhulu ngabadla imifino - sinezakhiwo ze-antioxidant, zilungele inhliziyo nesikhumba. Kodwa muva nje, kuthathwe esinye isinyathelo esingathi sína ocwaningweni lwezakhiwo ezizuzisayo zetiye eliluhlaza. Ososayensi abavela eNyuvesi yaseBasel (eSwitzerland) bathola ukuthi itiye eliluhlaza elikhishwe lithuthukisa imisebenzi yomqondo wobuchopho, ikakhulukazi, kwandisa i-synaptic plasticity yesikhashana - ethinta ikhono lokuxazulula izinkinga zomqondo futhi ibambe iqhaza ekubambeni ngekhanda okungcono.
Phakathi nocwaningo, amavolontiya wesilisa anempilo ayi-12 anikezwe isiphuzo se-whey esiqukethe amagremu angu-27.5 wetiye elihlaza (ingxenye yezifundo ithole i-placebo ukulawula injongo yocwaningo). Ngesikhathi nangemva kokuphuza isiphuzo, izihloko zokuhlolwa zafakwa i-MRI (ukuhlolwa kobuchopho ngekhompyutha). Babe sebecelwa ukuba baxazulule izinkinga ezihlukahlukene zobuhlakani. Ososayensi babone ikhono elandiwe ngokuphawulekayo lalabo abathola isiphuzo nge-extract yetiye ukuxazulula imisebenzi nokukhumbula ulwazi.
Naphezu kweqiniso lokuthi kuye kwenziwa izifundo eziningi ngetiye eliluhlaza emazweni ahlukene esikhathini esidlule, odokotela baseSwitzerland abakwazile ukufakazela umphumela onenzuzo wetiye elihlaza emisebenzini yokuqonda. Baze bakhomba indlela eyenza izingxenye zetiye elihlaza: zithuthukisa ukuxhumana kweminyango yayo ehlukene - lokhu kwandisa ikhono lokucubungula nokukhumbula ulwazi.
Ngaphambilini, ososayensi sebevele bafakazela izinzuzo zetiye eliluhlaza inkumbulo kanye nokulwa nomdlavuza.
Asikwazi ukuzibamba kodwa sijabule ngokuthi isiphuzo semifino esithandwa kangaka njengetiye eliluhlaza siphenduke saba usizo nakakhulu kunalokho obekucatshangwa ngaphambili! Ngempela, kanye nobisi lwe-soy kanye ne-kale (okuye kwafakazela isikhathi eside ukuthi iwusizo), itiye elihlaza ekuqapheliseni okuningi liwuhlobo "lommeli", inxusa, uphawu lokudla imifino ngokujwayelekile.
