Mukudziwa kuti kusuta ndichinthu choyipa kwambiri chomwe mungachite mthupi lanu-kuchokera mkati mpaka kunja, fodya ndiwowopsa pathanzi lanu.

"Kafukufuku wathu wapeza umboni wosatsutsika wakuti kusuta kumakhala ndi zotsatira zokhalitsa pa makina athu a maselo, zotsatira zomwe zingathe kupitirira zaka 30," anatero wolemba kafukufuku wotsogolera Roby Joehanes, Ph.D. Kafukufukuyu adayang'ana kwambiri methylation ya DNA, njira yomwe ma cell amayang'anira zochitika za majini, zomwe zimakhudza momwe majini anu amagwirira ntchito. Kuchita izi ndi njira imodzi yomwe kusuta fodya kumapangidwira omwe amasuta fodya ndi khansa, kufooka kwa mafupa, komanso matenda am'mapapo ndi mtima.

Ngakhale zotsatirazi ndizokhumudwitsa, wolemba kafukufukuyu adati akuwona zoyipa zomwe apeza: Kuzindikira kwatsopano kumeneku kungathandize ofufuza kupanga mankhwala omwe amalimbana ndi majini omwe akhudzidwawa mwinanso kupewa matenda ena okhudzana ndi kusuta.

A Joehanes akuti, anthu atasiya ntchito, malo ambiri omwe ali mu DNA adabwereranso "osasuta" patadutsa zaka zisanu, zomwe zikutanthauza kuti thupi lanu likuyesera kudzichiritsa lokha chifukwa chakusuta fodya.
