Busting The Myths On Coffee

Myth: Coffee dehydrates you

Reality: Regular moderate consumption of 3-4 cups of coffee a day can actually contribute to daily fluid intake (2). It’s wrongly thought that the caffeine in coffee has a diuretic action that will cause dehydration. Research shows that for regular coffee drinkers this effect is reduced. So, caffeine containing drinks won’t lead to excess fluid loss. (3-5)


Myth: Instant (soluble) coffee is not natural

Reality: There are no additives or chemicals used to make instant coffee, which is in itself 100% pure coffee beans. The only processing aid used to produce it is water.
