Sitat: "Contrary to popular belief, caffeine does not act as a diuretic when consumed in moderation, and does not lead to dehydration or to a water-electrolyte imbalance; current evidence suggests that caffeinated beverages contribute to the body's daily fluid requirements no differently from pure water.[27][28][29][30]"

Om du fortsatt lurer, sjekk de fire referansene i Wikipedia-artikkelen om den vanndrivende effekten. Derfra er det videre referanser til andre studier, metastudier osv.

Det var siste ord fra meg i denne diskusjonen. For det var vel ikke kaffe tråden skulle handle om?
