19. (A) Meanwhile the volume of their urine was measured regularly. (B) When it comes to the consumption of coffee, one study did find a 41% increase in urine, along with a rise in the excretion of sodium and potassium. (C) Every day people around the globe drink 1.6 billion cups of coffee and around twice as many cups of tea. (D) So although we might notice needing the loo more when we’ve been drinking coffee, the mistake is basing our observations on a comparison with the time we’ve drunk nothing, not with a similar amount of water. (E) But when you look at the studies of more realistic quantities of caffeine, the diuretic effect is not nearly so clear.
