Who’s to blame for Americans being overweight? Well some activists and trial lawyers want to point the finger at food and beverage companies. But according to a recent article on Foodnavigator.com, the vast majority of Americans think consumers themselves, not the makers of chips, cola, or chocolate bars, should shoulder the blame. Indeed of those surveyed, four in five agreed that Americans are eating too much and becoming more obese, but more than three-quarters don’t believe companies should be held legally responsible for our widening waistlines. But this issue is surely a heavy pocketbook one as well, with obesity-related medical costs in the U.S. now pegged at $75 billion per year.
