Russell: The Health and Nutrition Examination Survey (HANES), which measures nutrient status/intake and health status in a cross-section of the population, comes closest to this. It looks for disease trends (US Department of Health & Human Services 1996). Scott: There’s some comfort if they don’t see them. SETTING DIETARY INTAKE LEVELS 43 Taylor: This assumes you are measuring carefully what these people were taking. One of the problems that exists is that we are not collecting the right kind of data on the intake.
