The thing I found most interesting out this Consumer Reports report on carcinogens in Pepsi was Pepsi’s defense:
Consumer reports found the levels of caramel coloring in a can of Pepsi should require a cancer warning.
It [Pepsi] cited government consumption data that shows that the average amount of diet soda consumed by people who drink it is 100 milliliters per day, or less than a third of a 12-ounce can. For that reason, they believe that Pepsi One does not require cancer-risk warning labels—even if the amount of 4-MeI in a single can exceeds 29 micrograms.
So Pepsi is stating it can defend that its customers on average drink less than a third of a can a day (this argument is obviously flawed, because an open can of Pepsi goes flat in a couple hours..). Perhaps they are thinking when people have a couple freinds together the split a can 3 ways. Or, maybe they are saying that the average customer drinks one can every three days. Based on my not-to-scientific observations, I would say people either drink a lot of Pepsi every day or not at all.
So based on their defense – I consider them guilty as charged.
