范围内
mg per serving.
对比一下 每份煮好的咖啡含95至165毫克咖啡因
To compare, a serving of brewed coffee contains 95 to 165 mg of caffeine,
煮好的红茶
brewed black tea
含25至38毫克

美国有近2万人被送进急救室

一个观察性研究分析了7年间
An observational study reviewed 7 years
打给澳大利亚毒品信息中心的电话中有关能量饮料毒性的数据

因此如果你用等量的能量饮料代替八杯水

你的心率和血压会不断增加
the constant increases in heart rate and blood
这种增加可能会
pressure might lead to an increased risk of
导致诱发一系列心血管疾病的风险增加 包括高血压病

虽然关于含咖啡因的饮料
Though there is there is debate
是否会使人脱水还有争议

研究者发现含咖啡因的饮料会使尿量增加
have found that urine volume was increased
但是只有当咖啡因超过360毫克时
by caffeinated beverages, but only when they
才会这样
exceeded 360 mg.
一个单独的研究也发现
A separate study also found that
尽管能量饮料相比不含咖啡因的饮料
though energy drinks cause you to urinate significantly
会使尿液显著增加 相对于咖啡他们也不是利尿剂
more than non caffeinated beverages, they were no more a diuretic than coffee. However,
然而一杯黑咖啡少于5卡路里
a cup of black coffee has less
但是能量饮料有很高的糖含量
than 5 calories, but the high sugar content of
这就意味着卡路里大约有850卡路里
energy drinks means a calorie count of about 850 calories
在八杯红牛中

比如一个26岁的男人
such as a 26 year old man who drank at least two
十年间每天至少喝两罐能量饮料
cans of energy drinks daily for a decade.
没有任何重大的健康问题
With no prior significant health issues,
突然癫痫发作昏迷了三天
he had a seizure and fell into a three day coma.
医生最终将这归结于长期睡眠不足
Doctors ultimately attributed this to chronicsleep deprivation and over-consumption of
以及过度饮用咖啡因
caffeine.
饮用能量饮料与失眠症和扰断睡眠模式有关

美国45%现役的军事人员每天喝一罐能量饮料

据报道这些“三加”的饮用者
