RESULTS: Average frequency of meals consumed away from home increased from 1998 to 2012, although it remained lowerthan that of meals at home. In addition, male, unmarried, employed, higher educated, and high income individuals morefrequently consumed meals away from home. Moreover, sodium intake while eating-out significantly increased from 2,370mg in 1998 to 2,935 mg in 2012. Lastly, percentage contributions of daily total protein intake, fat intake, and sodium intakefrom eating-out increased to more than half (53-55%) in 2012 compared with 47-48% in 1998. CONCLUSIONS: As eating-out has grown in popularity, greater recognition of public health and nutritional education aimedat promoting healthy food choices is needed. In addition to developing consumer education for overall healthier eating patterns,individuals who are younger, unmarried, higher educated, and males are especially at risk and require attention.
