我们都知道为身体补充足够水分很重要。咖啡和茶是饮料，多喝是否也有助于补充水分呢？《活得好》请黄廷方综合医院营养师吴恩琪解析。
营养师吴恩琪说，咖啡、茶和罐装饮料的确是水分的来源，但这些饮料通常含有咖啡因或添加糖，不宜多喝。
咖啡和茶里的咖啡因具有温和的利尿作用，可能导致排尿更频繁，不过，除非长期大量喝，否则，一般不会导致脱水，所以不必过于担心。
饮用含糖饮料，则会增加肥胖、糖尿病和心血管疾病的风险。
对于年长者，若觉得白开水淡而无味，可适量饮用的替代品包括：水果风味水（把水果泡在白开水直至果味渗出，fruit infused water）、无糖或零热量饮料，以及无糖茶饮（生姜茶、香茅茶或菊花茶）
提醒！随着年龄增长，对口渴感觉可能变得没那么敏感，因此一些年长者即使体内缺水也不察觉，脱水风险也更高。即使不感到口渴，也要留意可能脱水的迹象：疲劳无力、头痛、头晕、口干、较少排尿和尿色深。
