Today’s retail environment is full of nutrition labels, claims, profiling systems and much more. Helping consumers navigate their way through grocery aisles is an important job, and according to the 2010 Dietary Guidelines for Americans, many Americans are overweight and undernourished. They get too many calories but not enough nutrients each day. The Guidelines further state that the prevalence of obesity in the United States has doubled and in some cases tripled between the 1970s and 2008.
