Caffeine and Increased Miscarriage Risk – A Portion Problem?

January 21, 2008

I haven’t yet read the study that has been widely reported as demonstrating that caffeine consumption can increase the risk of miscarriage. However, this quote from one of the researchers, regarding the problem of consuming 200 mg caffeine stood out to me:

That’s about the amount of caffeine in two five-ounce cups of coffee, five 12-ounce cans of soda or six five-ounce cups of tea, Li said.

Who drinks 5-ounce cups of coffee?!? Seriously. I dare somebody to try to even find a 5-ounce coffee cup, at home or from a coffee place. And no, the teacups in your grandmother’s china set that you never take out of the cabinet don’t count.

Seriously, though, I think we’re on the whole pretty bad at estimating portion sizes, and the amount of caffeine is going to vary among different brews. It’s going to be exceedingly difficult for individuals to determine what 200 mg of caffeine is in beverages they make themselves.
