2012 Annual Report
Objective 2: Develop methods for assessing patterns of energy expenditure that include a) validation of breath markers as indicators of energy substrate utilization and; b) characterization of seasonal patterns of energy expenditure and balance in free-living individuals using novel applications of existing technologies (e.g., GPS, accelerometry, heart rate monitoring, doubly labeled water).
This project includes an examination of the role of Atlantic salmon consumption as a source of omega-3 fatty acids for humans. This project is a collaboration with the ARS-National Cold Water Aquaculture Center, Franklin, ME. We demonstrated that baking salmon decreases the presence of fatty acid oxidation products without decreasing the content of beneficial omega-3 fatty acids in salmon. We have submitted one paper demonstrating that eating baked salmon increases blood omega-3 fatty acids in a dose-dependent manner and these data were presented at the 2012 Experimental Biology meeting.
This project includes an examination of the role of community-based lifestyle intervention in weight loss and improvements in body composition, fitness, and chronic disease risk biomarkers. The manuscript of results is currently being prepared and these data were presented at the 2012 Experimental Biology meeting.
This project includes a validation study of the use of resonance Raman spectroscopy for measuring skin carotenoid levels as a non-invasive tool to assess fruit & vegetable (F&V) intake (blood carotenoid levels are the current standard biomarker for F&V intake). This project is a collaboration with investigators at Yale University and the University of Utah. Data collection for half of the volunteers is completed; the 2nd half of the volunteers completed the study in August 2012. One abstract has been published (and presented as an oral abstract at the annual Experimental Biology meeting.
This project includes a description of barriers and facilitators to following the dietary guidelines reported by 5th grade American Indian children and parents. This is a collaboration with investigators at Candeska Chikina Community College. Data collection is complete. One abstract has been published and presented as an oral abstract at the annual Experimental Biology meeting.
