美国疾病控制与预防中心的一份新报告显示，年龄在2至19岁之间的美国儿童中，近三分之二的饮食中含有咖啡因。
据周四发布的这份报告显示，儿童日均摄入咖啡因总量平均为19.4毫克，约等于一罐可口可乐所含咖啡因的三分之二。
哥伦比亚广播公司新闻医疗记者塞琳·冈德博士在《CBS晨间新闻》节目中表示，健康专家目前尚不明确儿童摄入多少咖啡因才算过量。美国儿科学会建议儿童不应摄入任何咖啡因。
研究人员同时发现，汽水并非儿童摄入咖啡因的唯一途径。
对于2至11岁的儿童而言，布朗尼、曲奇和糕点等被报告称为“甜烘焙食品”的零食是咖啡因的首要来源。
“问题出在含有咖啡因的巧克力，”冈德说道。
对于该年龄段儿童，这类烘焙食品之后依次是调味牛奶、糖果、汽水和茶。而对于12至19岁的青少年，汽水是最大的咖啡因来源，紧随其后的分别是甜烘焙食品、茶、咖啡和糖果。

冈德指出，咖啡因会影响部分儿童的睡眠质量。
根据2021年发表在《食品与化学毒理学》期刊上的一项研究，摄入少量咖啡因的13至15岁儿童中，有3%每晚睡眠不足6小时。而在摄入大量咖啡因的同年龄段儿童中，这一比例升至24%。
“这也一定程度上取决于摄入时间，如果他们在晚间摄入咖啡因的话，”冈德说。“所以不只是晚间不宜喝咖啡。如果是儿童，晚间也最好不要吃那些蛋糕和曲奇。”
Nearly two-thirds of kids have caffeine in their diet, the CDC says. It’s not all coming from soda.

A new report from the Centers for Disease Control and Prevention found that nearly two-thirds of American children aged 2-19 have caffeine in their diet.
On any given day, kids consume an average of 19.4 milligrams of caffeine, which is about two-thirds of what’s in a can of Coke, according to the report released Thursday.
CBS News medical correspondent Dr. Céline Gounder said on “CBS Mornings” that health experts don’t know how much caffeine is considered to be too much for children. The American Academy of Pediatrics recommends that childrenshouldn’t consume any caffeine.
Researchers also found that sodas aren’t the only way caffeine is getting into kids’ diets.
For kids aged 2-11, goodies like brownies, cookies and pastries — called “sweet bakery products” in the report — were the top source of caffeine.
“It’s the chocolate that has the caffeine,” Gounder said.
The baked goods were followed by flavored milk, candy, soda and tea, respectively, for that age group. For those aged 12-19, soda was the top source, followed closely by sweet bakery products and then tea, coffee and candy.

Gounder noted that caffeine can affect how some children sleep.
According to a 2021 study in the journal Food and Chemical Toxicology, 3% of kids aged 13-15 who consumed a low amount of caffeine got less than six hours of sleep a night. That increased to 24% for those in that age group who had a high amount of caffeine.
“Some of this also depends on timing, if they’re having the caffeine in the evening,” Gounder said. “So it’s not just you don’t want to have coffee in the evening. If you’re a kid, you may not want to have that cake and cookies in the evening either.”
