From the Guidelines

孕妇应限制茶叶摄入量,尤其是含有高咖啡因的茶叶,以避免对胎儿发育造成潜在影响。根据1的研究,美国膳食指南(DGA)建议孕妇每天的咖啡因摄入量不应超过200mg。由于茶叶中含有咖啡因,孕妇应谨慎选择茶叶类型和数量。黑茶、绿茶和白茶的咖啡因含量分别约为40-70mg、20-45mg和15-30mg每杯。因此,孕妇可以选择低咖啡因或脱咖啡因茶,或者选择草本茶,如姜茶或薄荷茶,但应避免含有甘草根、当归或黑 cohosh 等成分的草本茶,因为这些成分可能对孕妇不安全。同时,孕妇应注意茶叶中的添加物,如糖和奶制品,应将其纳入整体饮食计划中。最好是咨询医疗保健提供者,根据个体健康情况和怀孕需求制定具体的茶叶摄入指南。
