Mandatory calorie posting is one measure taken by the government that effectively raises awareness and induces positive decision making among customers. After calorie posting was put into full enforcement in May 2008, customer awareness of calorie information rose from 25% to 64% (Dumanovsky et al. 2522). This increase of customer awareness allowed more consumers to make healthier choices. Post-enforcement, twenty percent of customers reported that calorie information affected their purchase As opposed to ten percent before enforcement. Customers of the restaurant franchise Subway who reported seeing and using calorie information “purchased 99 fewer calories” customers who were not aware of the calorie information (Dumanovsky et al. 2521). Calorie postings are proven to have a positive influence on the decisions of consumers. Consumers tend to be inaccurate in estimating the calories in their purchased beverages and foods (Bollinger, Leslie, and Sorensen 116-117). At Starbucks, 76.9 percent of consumers underestimated the calorie amounts of their food; the average was an underestimate of 61.6 calories. This goes to show that without nutritional disclosure, consumers have a hard time approximating the caloric content and nutritional value of the foods they purchase. Starbucks cardholder data was analyzed to see if the habits of customers changed after seeing nutritional information (Bollinger, Leslie, and Sorensen 119). It showed that after visiting Starbucks stores in NYC that displayed calorie information, the consumers’ visits to stores outside of NYC where caloric information was not displayed showed calorie reductions as well (Bollinger, Leslie, and Sorensen 120). Consumers are not aware of the actual nutritional content of the foods they purchase until viewing posted nutritional information. After using such information, however, consumers will adopt those healthier purchasing habits even when the information is not displayed. As calorie
