第一批喝泰奶的“受害者”已经出现了……
Thai milk tea has become one of the hottest drinks in China, but many consumers may not realize just how much caffeine and sugar a single cup contains.
咖啡因“警报”
“泰奶”是人们对“泰式奶茶”的简称。
传统泰式奶茶是以水、泰式红茶粉(其中常混合肉桂、八角、豆蔻、香茅等天然香料)、炼乳、淡奶、白砂糖或糖浆为主要原料,冰镇制成的街头饮料。现在茶饮品牌们推出的“泰奶”饮品,也都是在这个基础上进行的调整。
Traditional Thai milk tea is a street drink made with water, Thai black tea powder — often blended with spices like cinnamon, star anise, cardamom and lemongrass — condensed milk, evaporated milk and sugar or syrup, served over ice. Drinks sold by tea brands today are variations on that base.
但和一般奶茶不同的是,泰奶的茶基底,因为茶粉颗粒更细小、萃取更充分,咖啡因溶出得也更快、更多。
What sets Thai milk tea apart from regular milk tea is its tea base. Because the tea powder is finer and more thoroughly extracted, caffeine dissolves faster and in greater amounts.
按照香港食安中心提供的数据,港式奶茶咖啡因含量在170~220毫克/杯之间。不过,港式奶茶选用的并非红茶粉,而是粗、中、幼茶叶碎末拼配的碎茶,颗粒比茶粉更大,理论上咖啡因萃取率应该比泰式奶茶低,由此推测,泰式奶茶的咖啡因含量应该更高。
比如某品牌经典泰奶(中杯)的咖啡因含量为 137.3 毫克,高于同品牌、同规格拿铁(98.6 毫克),和标准美式接近(164.3 毫克)。
A medium cup of one brand's classic Thai milk tea, for example, contains 137.3 milligrams of caffeine — higher than the same brand's latte of the same size at 98.6 milligrams, and close to a standard Americano at 164.3 milligrams.
可是很多人都没意识到这一点,拿泰奶当普通奶茶喝,结果就是“咖啡因暴击”:
“两点我还醒着,发誓再也不喝了。”
“刚喝完心怦怦的。”
“刚喝的时候感觉挺好喝的,看电影的时候突然心悸,头晕恶心想吐,但又吐不出来,一开始还以为是看恐怖片吓得,但这个恐怖片它也不吓人啊,闭上眼歇了一会儿还是很难受。对咖啡因敏感的人不要点啊。”

含糖量“警报”
泰奶还有一个问题就是,含糖量也非常高。
那些遵照传统做法制作的泰奶,都加入了大量的炼乳、淡奶,高糖又高脂。而且,大家喝泰奶,往往都是喜欢其甜蜜丝滑的口感,很多人不会像点其他奶茶那样,专门选“低糖、无炼乳版本”。这就导致糖摄入量简直“满负荷”。
Thai milk tea also tends to be very high in sugar. Traditional versions use large amounts of condensed and evaporated milk, making them high in both sugar and fat.
按照中国营养学会“成人咖啡因安全摄入量不超过400毫克/天,添加糖不超过25克/天”的建议,如果每天喝一杯泰奶,再吃点别的零食,很容易就超标了。
China's Nutrition Society recommends adults consume no more than 400 milligrams of caffeine and 25 grams of added sugar per day. One cup of Thai milk tea plus some snacks can easily exceed those limits.
想保住睡眠和体形
这么喝泰奶更“安全”
为了保住我们的睡眠、血糖血脂健康以及良好体形,无论是点外卖还是在家自制,都要稍微注意几个原则:
①点外卖这样选更健康
如果品牌标注咖啡因含量,优选咖啡因含量低的;
选择少加或不额外加糖,少加其他配料,如乳酪、焦糖、珍珠;
优选小杯少量喝,点了中杯和同事、家人分着喝;
喝了泰奶,可就不能喝别的甜饮料/吃甜品了哦~再能少吃点主食更好。
When ordering out, choose lower-caffeine options if the brand lists caffeine content, ask for less or no added sugar, skip extras like cheese foam, caramel or pearls, and opt for a small cup or share a medium one. After drinking Thai milk tea, avoid other sweet drinks or desserts, and consider cutting back on staple foods.
②在家自制这样避坑
减少泰式红茶粉用量或换成完整红茶,降低咖啡因溶出效率;
缩短熬煮、浸泡时间,或用冷泡代替,减少咖啡因溶出量;
少用或不用炼乳,只加淡奶、鲜奶;
少加、不加糖,或用糖醇替代;
自制别过夜,保存不好容易变质。
For homemade versions, use less Thai tea powder or switch to whole-leaf black tea, shorten brewing or steeping time, or cold-brew instead to reduce caffeine. Use little or no condensed milk, add only evaporated or fresh milk, cut back on sugar or use sugar substitutes, and don't keep it overnight.
想做健康版泰奶平替,还可以试试这个配方:
一小根肉桂、两颗拍碎的肉豆蔻加水煮出香味后,过滤掉香料将水放至温热,加入普通红茶包,密封放冰箱冷藏过夜,加入1/4淡奶和3/4牛奶、一小勺赤藓糖醇。
茶香、奶香、香料香都有了,但糖分、脂肪和咖啡因含量都下降了,不失为一杯惬意奶茶吧!
