Beware of Brown Rice Syrup?

In a study published in Environmental Health Perspectives, researchers question the safety of Organic Brown Rice Syrup (OBRS) as a sweetener in gels.  There are no current regulations regarding Arsenic in food, however bars and high energy foods containing OBRS also had higher As concentrations than equivalent products that did not contain OBRS.  I doubt that occasional gel use will become a problem, but taking a gel every 30minutes during a 140.6 event could, theoretically, result in increased arsenic levels in the body.
