Coffee could come with a warning in California

California coffee shops may soon be forced to warn customers about a possible cancer risk. A lawsuitagainst several coffee makers and sellers alleges that they "failed to provide clear and reasonable warning" that drinking coffee could expose people to acrylamide. The chemical is created when coffee beans are roasted. California keeps a list of chemicals it considers possible causes of cancer. Acrylamide is on that list. The coffee industry argued before a judge that the level of acrylamide in coffee should be considered safe and that the health benefits of coffee essentially outweigh the risk. A decision by the judge is pending.

Regardless of that ruling, there's sure to be another meta-study, and another opinion. We'll keep you updated.
