This is just another example of the sad state of affairs in our country (as I assume this is US only). Seriously, a product contains chocolate ... it's not a healthy everyday food product. Granted, there are studies that strongly suggest chocolate has good health benefits, but that is not ALL chocolate as all chocolate is not of the same quality ... AND they weren't talking about eating chocolate everyday as part of a meal.
Yes, everyone is responsible for their own health as best you can (depending on economic level, etc etc), so you should read labels and make informed decisions. That lawsuit should have been thrown out. However, the company should have been fined for misleading advertisements. So both parties should have lost out on their greed an stupidity.
