Brief Summary:
The primary objective of this study is to test effectiveness of an environmental intervention designed to encourage healthy food intake during meals. It is hypothesized that fruit, vegetable, whole grain, lean protein, and low-fat dairy consumption will increase during the intervention. It is also hypothesized that nutrition knowledge, attitudes, and behaviors will change as a result of the intervention. The findings from this study will provide insight into the applicability of this intervention in military dining facilities.

Condition or disease Intervention/treatment Phase
Dietary Habits Health Knowledge, Attitudes, Practice Other: Healthy meal plates and trays Not Applicable

Detailed Description:
Previous studies attempting to increase consumption of healthy foods in military dining facilities have had mixed results, and alternative approaches need to be considered. The present intervention was designed with the results of previous studies in mind, and as such, does not focus on labeling only healthy food choices. Instead, the present intervention aims to encourage consumption of nutritionally well-balanced meals using an environmental cue in military dining facilities.

Arm Intervention/treatment
Experimental: Short Intervention
All participants will be measured for (1) baseline, (2) two-week environmental intervention: Healthy meal plates and trays, and (3) withdraw of intervention.
Other: Healthy meal plates and trays
The healthy meal plates and trays provide guidance for how to construct a meal in the military dining facility.

Experimental: Long Intervention
All participants will be measured for (1) baseline, (2) four-week environmental intervention: Healthy meal plates and trays, and (3) withdraw of intervention.
Other: Healthy meal plates and trays
The healthy meal plates and trays provide guidance for how to construct a meal in the military dining facility.




Primary Outcome Measures :
  1. Change in dietary intake [ Time Frame: Participants will be followed for 6-12 weeks ]
    Dietary intake will be assessed at lunches eaten in military dining facilities using the food photography method. The change in dietary intake from baseline to intervention will be assessed.


Secondary Outcome Measures :
  1. Change in nutrition knowledge [ Time Frame: Measured at beginning and end of the 6-12 week study. ]
    Nutrition knowledge specific to the intervention will be assessed with an experimenter-developed questionnaire.

  2. Change in nutrition attitudes and behaviors (composite) [ Time Frame: Measured at the beginning and end of the 6-12 week study. ]
    Nutrition attitudes and behaviors will be measured with a single composite experimenter-developed questionnaire.
