Assessing nutritional fitness

Assessing Nutritional Fitness

  • Tools

    • Survey and Diary

    • Direct Observation

    • Assessment of Physiological Markers

  • Standards

    • Military Recommended Dietary Intake (MRDI)

    • Food Group Recommendations (e.g., Healthy People 2010)


Measuring success metrics

Measuring Success: Metrics

  • Healthy People 2010

    • Eat at least 2 servings of fruit per day. Target: 75%

    • “ “ 3 servings of vegetables per day. Target: 50%

    • 3 servings of whole grain products/day. Target: 50%

    • Consume less than 30% of calories from fat. Target: 75%

    • Increase # worksites that offer nutrition or wt. mgmt. classes or counseling. Target: 85%


Promoting healthy eating behavior civilian cafeteria research

Promoting Healthy Eating Behavior -Civilian Cafeteria Research

Nutrient Content Manipulation of ad lib diet

  • Jayhawk Observed Eating Trial (Donnelly et al., Obesity. 2008)

    • 305 sedentary normal & overweight men & women, reduced fat diets

      • Only effective in weight loss when energy intake was reduced

        Ad lib food choice can be manipulated

  • Harvard SPH Cafeteria Study (Michels, et al., J Am CollNutr. 2008)

    • Educational displays

    • Price subsidies for “healthy” selections

Why are french fries & hotdogs cheaper than salad?

Promoting Healthy Eating Behavior -Civilian Cafeteria Research

NIH-funded Cafeteria Study (Lowe, et. al., unpublished ongoing project)

  • Detailed food labeling

  • Greater number “healthy” selections

  • Price subsidies for reduced energy density items

    Yale NSLP Study (Schwartz, Int. J. Behav. Nutr. Phys. Act. 2007)

  • Verbal prompts by servers encourage fruit selection

    ”Sargent Choice” at Boston University

  • Logo label “healthy” food choices throughout DFACs

  • Measurements

    • Ad lib food selections & intake, demographics & satisfaction ratings
