The NWRC aims to promote health and wellness using the following interventions:

  • Dietary intake (functional foods, food ingredients, plants, dietary supplements)
  • Physical activity/exercise
  • Health-related behaviors

 

Studies completed at the NWRC (Research Park and campus facilities)

In the two years since the NWRC officially opened, researchers have completed a number of clinical trials involving human participants.  This represents over $3.7 million in total project funding and research in areas including: 

 

Exercise/Physical Activity and Assessment of Energy Expenditure

    • Acute, intense exercise on immune response
    • Validation of armband monitors using doubly-labeled water in adults
    • Modeling blood glucose response to physical activity & dietary intake in Type II diabetics using indwelling glucose sensors

Health-Related Food Components/Supplements and Dietary Factors

    • Flaxseed products on circulating cholesterol concentration
    • Novel dietary fiber supplements on appetite and satiety
    • Fermented dairy beverage on glycemic index and satiety
    • Digestive-resistant starches on blood glucose and gastrointestinal fermentation
    • Soy isoflavones on bone mineral density in postmenopausal women
    • Soy isoflavones on central adiposity/body composition in postmenopausal women
    • Soy foods on iron and zinc status and biochemical bone markers in young women
    • Retinol activity and absorption of beta-carotene-biofortified crops
    • Bioavailability of carotenoids, vitamin K, and tocopherols with salad dressing
    • Folate, plasma homocysteine, and methyl group metabolism
    • Vitamin D status and physical performance
Behavioral Choices and Change

    • Influence of perceived pleasure/displeasure on future activity/exercise choices
    • Consumer willingness to purchase higher priced ground beef with extended shelf life
