Comparative validation of the Block, Willett, and National Cancer Institute food frequency questionnaires : the Eating at America's Table Study.
Data show that the DHQ and the Block FFQ are better at estimating absolute intakes than is the Willett FFQ but that, after energy adjustment, all three are more comparable for purposes of assessing diet-disease risk.
Update of the Healthy Eating Index: HEI-2015.
Using intake biomarkers to evaluate the extent of dietary misreporting in a large sample of adults: the OPEN study.
There was little underreporting of the percentage of energy from protein for men or women, and unbiased biomarkers of energy and protein intakes: doubly labeled water and urinary nitrogen have important implications for nutritional epidemiology and dietary surveillance.
The Automated Self-Administered 24-hour dietary recall (ASA24): a resource for researchers, clinicians, and educators from the National Cancer Institute.
A new statistical method for estimating the usual intake of episodically consumed foods with application to their distribution.
Structure of dietary measurement error: results of the OPEN biomarker study.
Results suggest that the interpretation of findings from FFQ-based epidemiologic studies of diet-disease associations needs to be reevaluated because using the 24HR as a reference instrument can seriously underestimate true attenuation.
Fruit, vegetables, and cancer prevention: a review of the epidemiological evidence.
It would appear that major public health benefits could be achieved by substantially increasing consumption of fruit and vegetable consumption, and in particular in cancers of the esophagus, oral cavity, and larynx, for which 28 of 29 studies were significant.
Americans do not meet federal dietary recommendations.

Nearly the entire U.S. population consumes a diet that is not on par with recommendations, adding another piece to the rather disturbing picture that is emerging of a nation's diet in crisis.
Fruit and vegetable assessment: performance of 2 new short instruments and a food frequency questionnaire.
Design and serendipity in establishing a large cohort with wide dietary intake distributions : the National Institutes of Health-American Association of Retired Persons Diet and Health Study.
In establishing a cohort of 567,169 persons (340,148 men and 227,021 women), the authors were fortunate in that a less-than-anticipated baseline response rate was offset by both a shifting and a widening of the intake distributions among those who provided satisfactory data.
