多少咖啡因的绿茶和红茶？
The exact caffeine content in tea can vary due to many factors, including growing conditions, harvest time, preparation, packaging, and brewing method. But British researchers found that in general, green tea has about half the caffeine of black tea. On average, green tea has about 24mg of caffeine per 8 oz (237 ml) cup, while black tea has about 47mg.
脱咖啡因茶仍然有咖啡因的一些非常小的量，虽然这是几乎可以忽略的 - 大约1至2毫克每8盎司（237毫升）杯。如果你想完全避免咖啡因，去凉茶，它没有咖啡因的。
让你自己的低咖啡因绿茶
Decaffeinated green tea is often poor quality tea that doesn’t taste very good. But if you don’t want caffeine in your tea, it’s pretty easy to decaffeinate it yourself. Luckily, the caffeine in green tea is very water soluble, but the healthy antioxidants are not. So you can remove 90 percent of the caffeine in green tea by following these steps:
- 开始与任何优质绿茶，你享受
- Boil some water
- 泡在开水松散的茶叶为30 -45秒
- Remove the water by pouring the tea leaves through a strainer
- 冲泡茶叶，你通常会
你会得到所有的抗氧化剂的健康益处同样美味的茶，但是去除了咖啡因的约90％！由于韦医生这个伟大的小费。
在绿茶和红茶卡路里
当你喝热茶，你不需要对卡路里的担心。绿茶具有零个卡路里，红茶每8盎司（237毫升）杯只有大约2卡路里。所以这是一个聪明的选择饮料。
BUT, don’t add any sugar to your tea!It’s OK to add lemon. But if you add sugar, your healthy, zero calorie drink will quickly become an unhealthy source of empty calories.
Watch Out for the Calories in Iced Tea!
因为茶就是这样一个健康的，几乎零热量的饮料，你会认为冰茶是在热天的绝佳选择。但是，你就错了！
大多数冰茶装有糖，它可以是不健康的，你的苏打水。您还可以得到额外的钠 - 没有业务在饮料是另一种成分。所以，除非你酿造自己冰茶（和你跳过糖），你应该避免。冰茶不是一个明智的选择饮料。谁需要空热量？

I recently started using green tea to reduce my tummy. How many cups I should drink each day. At the moment I drink one cup at night. Please advise. Thanks. B
If possible, you should try for 3 -4 cups per day. That will help you lose about 1 pound per month. If you combine the green tea with diet and exercise, you’ll see better results. Don’t drink more than 4 cups per day, since there will be no additional benefit. Also, green tea does have some caffeine. So if you have trouble sleeping, you should avoid drinking it in the late afternoon or evening.
祝你减肥！
