Scientific titleDietary biomarker discovery using metabolomics
Study hypothesisCurrent strategies for reducing chronic disease burden in the UK and elsewhere emphasize the importance of changing dietary habits. Developing population level dietary interventions and monitoring their effectiveness require robust tools for assessing dietary exposure in large scale studies. The aim of the present study is to identify novel chemicals in blood and urine that are associated with a healthy diet. Volunteers will be given diets differing in amounts of specific test foods deemed to have high public health importance (oily fish, wholegrain foods, fruits and vegetables). Whilst provided with these diets urine and blood samples will be collected to determine new ‘biomarkers’ for these different food sources.
Ethics approval(s)13/LO/0078; First MREC approval date 28/01/2013
ConditionTopic: Primary Care Research Network for England; Subtopic: Not Assigned; Disease: All Diseases
InterventionExcellent diet, 100% healthy eating target
Good diet, 75% health eating target
Medium diet, 50% healthy eating target
Poor diet, 25% of health eating target

Follow Up Length: 1 month
Study Entry: Single Randomisation only

A formal power calculation is not possible as this will be the first study of its type. However, recent studies have demonstrated significant changes in metabolomics profiles in cohorts of 20 volunteers. Allowing for a dropout rate of 33% we intend to recruit 30 volunteers for the research.
