미 FDA에서는 하루 3잔이하를 권장한다. 카페인의 농도에 따라 하루 1-2잔 정도로 제한하는 것이 안전하다.

* 5잔 이상 마시면 유산이 증가한다는 보고가 있다. ((Extremely high serum paraxanthine(serum marker of caffeine consumption) were associated with abortion  which dose of equivalent to more than **5** cup of coffee per day. //wiliams 21st p.242//))
  * 많이 섭취할 수록 유산, 사산이 증가한다는 보고가 있다. ((Compared to those consuming < 100 mg/day, odds ratios increased to 2.2 (95% CI: 0.7-7.1) for 100-199 mg/day, 1.7 (0.4-7.1) for 200-299 mg/day, and 5.1 (1.6-16.4) for 300+ mg/day (P (trend) = 0.004). Greater caffeine intake is associated with increases in late miscarriage and stillbirth. Despite remaining uncertainty in the strength of association, our study strengthens the observational evidence base on which current guidance is founded. // [[http://www.ncbi.nlm.nih.gov/pubmed/20306287|Eur J Epidemiol. 2010 Apr;25(4):275-80. Epub 2010 Mar 21]]//))
  * 하루 4잔을 넘으면 합병증이 증가한다는 보고가 있다.((Relative to nonconsumers of coffee, the adjusted hazard ratios for fetal death associated with coffee consumption of **1/2-3, 4-7, and > or =8 cups of coffee per day** were **1.03** (95% confidence interval (CI): 0.89, 1.19), **1.33** (95% CI: 1.08, 1.63), and **1.59** (95% CI: 1.19, 2.13), respectively. Reverse causation due to unrecognized fetal demise may explain the association between coffee intake and risk of fetal death prior to 20 completed weeks' gestation but not the association with fetal loss following 20 completed weeks' gestation. Consumption of coffee during pregnancy was associated with a higher risk of fetal death, especially losses occurring after 20 completed weeks of gestation. //[[http://www.ncbi.nlm.nih.gov/pubmed/16207803|Am J Epidemiol. 2005 Nov 15;162(10):983-90. Epub 2005 Oct 5.]]//))
  * 하루에 섭취하는 카페인의 양이 200mg을 넘으면, 유산확률이 두 배 (25%)로 증가한다는 보고가 있다. ((A new study in San Francisco of 1,000 women in their first trimester has shown a doubling of miscarriage at 200 mg of caffeine per day. That's about the amount of caffeine you'd get if you drank 2 small cups of coffee or 5 cans of caffeinated soda. (Women who drank 200 mg. of caffeine per day had a miscarriage rate of 25 percent; those who drank 100 mg per day had a miscarriage rate of 15 percent, and those who drank no caffeine had a rate of 12 percent.))
