Speaking of coffee, this recent study declares that coffee, despite the slight diuretic effects of caffeine, hydrates just as well as water. Nice to see this confirmed, though I never had any doubts.
It’s also worth giving extra attention to the final paragraph of the article:
She and her colleagues noted that public health recommendations to exclude caffeinated beverages from daily fluid needs or to drink a glass of water for every cup of coffee or tea consumed “should be updated to reflect [our] findings.”
I agree—but seriously, good luck with that one. Modern public dietary recommendations are embarrassingly behind the times, scientifically speaking.
