I cannot believe that the Nebraska study was even published with only 18 people in the study. Amazing.

And down at Duke where some researcher did a study of 150 people on low-fat v. Atkins' diet, even that researcher admitted that 150 was too low of a number from which to draw scientifically sound conclusions. Not that conclusions are given much weight, it seems to me, with studies controverting previous studies all over the place.

However, I honestly think wwh has made the most telling point:

If hospitals are run on coffee, then there sure as heck doesn't seem to be much real danger in caffeine.
