Abashakashatsi bagaragaje ko kunywa hagati ya miligarama 200 na 300 za caféine ku munsi, zingana n’ibikombe bibiri cyangwa bitatu by’ikawa bitewe n’ubwoko n’ingano yayo, byari bifitanye isano no kugabanuka kw’ibi byago.
Icyakora, abahanga baraburira ko ibi bidahagije kugira ngo hemezwe ko ikawa ubwayo irinda cyangwa ikumira izo ndwara.
Ubushakashatsi bwakorewe ku bantu basaga 188.000
Ibyavuye muri ubu bushakashatsi byasohotse mu kinyamakuru cy’ubuvuzi Journal of Clinical Endocrinology & Metabolism.

Abanywaga caféine mu rugero bagaragaje ibyago bike
Nyuma yo gusesengura amakuru yakusanyijwe, abashakashatsi basanze abantu banywaga hagati ya miligarama 200 na 300 za caféine ku munsi bari bafite ibyago bike byo guhura n’indwara zimwe na zimwe ugereranyije n’abanywaga munsi ya miligarama 100 ku munsi.
Ibyo byari bikubiyemo indwara z’umutima, diyabete yo mu bwoko bwa kabiri ndetse n’indwara z’imitsi ijyana amaraso mu bwonko, zirimo stroke.
Abanywaga ikawa ni bo bagaragaje itandukaniro rikomeye kurushaho, kuko abashakashatsi basanze ibyago byo guhura n’indwara z’umutima n’izifitanye isano n’imikorere y’umubiri byaragabanutse ku kigero kigera hafi kuri 50% mu itsinda ry’abanywaga caféine ku rugero rwagaragaje inyungu.

Ku cyayi, inyungu zagaragaye cyane ku bantu banywaga hafi ibikombe bitatu ku munsi.
Icyakora, abashakashatsi bagaragaje ko kunywa birenze uwo mubare bitari ngombwa ko bikomeza kongera inyungu.
Ibi ni ingenzi kuko hari abantu bashobora kumva ko niba ikawa nkeya ishobora kugira isano n’inyungu runaka, kuyinywa nyinshi byaba byiza kurushaho. Ubushakashatsi ntabwo bubishyigikira.
Impuguke ziraburira abanywa caféine nyinshi

Ni yo mpamvu abahanga bashishikariza abantu kwita ku mirire muri rusange aho kwibanda ku kinyobwa kimwe gusa.
Ikawa ntabwo yasimbura imirire myiza n’imyitozoAbashakashatsi ntibavuze ko ikawa ivura cyangwa ikumira indwara z’umutima, stroke cyangwa diyabete.
