True or False: Caffeine can lead to dehydration if consumed in high amounts.

Caffeine is a diuretic, meaning it can increase urine production, which has led to the belief that it may contribute to dehydration. When consumed in high amounts, especially in individuals who are not accustomed to caffeine, it can potentially enhance fluid loss through urination. However, the actual risk of dehydration from caffeine consumption is more nuanced. For most habitual caffeine users, the body adapts to the effects, and the diuretic impact is less pronounced. Therefore, while it is possible for high caffeine intake to lead to dehydration, especially in non-habitual users or with excessive amounts, the context of use and individual tolerance levels are significant factors. Thus, the statement that caffeine can lead to dehydration if consumed in high amounts is generally accepted as true, particularly in specific populations or under particular conditions.
