Obese caucasians are at higher risk for developing acid reflux disease than obese individuals of other races. In a group of 80,000 patients obesity was found to increase risk by a fairly significant amount for Caucasians, while it seemed to have little or no effect on acid reflux for African-Americans or Asians.

I'm interested to know why this is, but unfortunately experts have no idea. What they do know is that Caucasians with the largest waists are as much as 85% more likely to get heartburn -- that's a big number! Seems unfair, but what ya gonna do? Try to slim down, that's what.
