Pure guess: nothing or slightly lower risk - millions of Asian and British women can't be wrong! OK, I had to hit PubMed: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12519715&dopt=Abstract "...Based on available evidence, it is suggested that reproductive-aged women should consume </=300 mg caffeine per day (equivalent to 4.6 mg kg(-1) bw day(-1) for a 65-kg person) while children should consume </=2.5 mg kg(-1) bw day(-1)." [Caffeine content of various drinks - check out Red Bull! **jolt!** I should note that this confirms my vaguely remembered ~ 100mg/cup coffee and ~ 30mg/cup black tea. But some of the soft drinks! Yikes! I had no idea!] http://wilstar.net/caffeine.htm http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12045799&dopt=Abstract "...CONCLUSION: There was no association between caffeine consumption during pregnancy and low birthweight, prematurity and intrauterine growth retardation." http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11428387&dopt=Abstract "...This study provides evidence that antenatal caffeine consumption has no adverse effect on fetal growth." http://www3.interscience.wiley.com/cgi-bin/abstract/83502181/START "...Thus, the overall conclusion is that caffeine is a chemical, among a long list of drugs and chemicals, that may have the potential to injure the embryo if used in marked excess. However, the usual range of human exposures to caffeine from food and beverages is below the threshold dose that would result in developmental/teratogenic or reproductive effects. Klebanoff et al. ('99), in the only study that has dealt with actual blood levels of caffeine metabolites, reached this conclusion with regard to caffeine consumption and spontaneous abortion. They concluded that moderate consumption of caffeine is unlikely to increase the risk of spontaneous abortion. Therefore, clinical teratology counselors, dysmorphologists, and genetic counselors can counsel prepregnant or pregnant women who do not smoke or drink alcohol and who consume moderate amounts of caffeine (<5-6 mg/kg per day spread throughout the day) that they do not have an increase in any reproductive risks..." The above published 2001 or since. A 2000 study that found an association between spina bifida and tea consumption nevertheless notes a decrease in anencephaly, which seems odd to me because both are neural tube defects. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11018418&dopt=Abstract Interestingly (although high caffiene intake is associated with reduced fertility in another study): http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=9491020&dopt=Abstract "...Drinking one-half cup or more of tea daily approximately doubled the odds of conception per cycle." I did ignore a study that noted a rise in rat birth defects at a caffeine dose of ~ *8000mg/day*... Debbi GSV Moderation __________________________________________________ Do you Yahoo!? Yahoo!
