啤酒和咖啡可以解渴吗?
Alcohol acts as a diuretic, which causes you to pass more urine, so when it comes to alcoholic beverages hydration will depend on a beverage's total volume. "Beer would result in less water loss than whiskey, because you are ingesting more fluid with beer," Maughan said. "Strong alcoholic drinks will dehydrate, dilute alcoholic drinks will not."
酒精有利尿作用,会让你排出更多尿液,因此酒精饮料的补水效果取决于摄入的酒量。莫恩说:“啤酒导致的水分流失比威士忌少,因为喝啤酒摄入的液体更多。烈酒会让人体脱水,低度酒精饮料则不会。”
diuretic[ˌdaɪjuˈretɪk]: n. 利尿剂
When it comes to coffee, how well your java hydrates you will depend on the amount of caffeine you consume. A regular coffee with about 80 milligrams of caffeine would be pretty much as hydrating as water, according to Maughan's research.
至于咖啡的补水效果则取决于你摄入的咖啡因总量。根据莫恩的研究,一杯含有约80毫克咖啡因的普通咖啡的补水效果和水差不多。
Consuming more than 300mg of caffeine, or about 2-4 cups of coffee, could cause you to lose excess fluid as the caffeine causes a mild, short-term diuretic effect. This is more likely to happen with someone who doesn't typically consume caffeine, and it could be offset by adding a tablespoon or two of milk to your cup of joe.
