Balance it with a healthy lifestyle. The healthier water method uses steam to remove the caffeine, so the coffee retains its flavour. The chemical method may leave a residue behind. It isn't usually stated on the label which method is used, but there are some clues. Gourmet coffee that comes from a single country or estate tends to retain its aroma more than a blend, which mixes beans from several countries and estates, said Ms Wong.
Blend also tend to taste harsher.
And don't drink coffee on an empty stomach. Coffee also makes you urinate more. In an extreme case, if you don't drink anything but coffee, you'll end up peeing very often and risk becoming dehydrated, said Ms Howden. Caffeine also steals calcium from your body. The amount of calcium lost is equal to about a tablespoon of milk per coffee cup.
