Comparative validation of the Block, Willett, and National Cancer Institute food frequency questionnaires : the Eating at America's Table Study.
TLDR
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. Expand
Using intake biomarkers to evaluate the extent of dietary misreporting in a large sample of adults: the OPEN study.
TLDR
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. Expand
Fruit, vegetables, and cancer prevention: a review of the epidemiological evidence.
TLDR
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. Expand
Structure of dietary measurement error: results of the OPEN biomarker study.
TLDR
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. Expand
A new statistical method for estimating the usual intake of episodically consumed foods with application to their distribution.
TLDR
The NCI method provides distinct advantages over previously proposed methods by accounting for the correlation between probability of consumption and amount consumed and by incorporating covariate information. Expand
Americans do not meet federal dietary recommendations.
TLDR
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. Expand
The Automated Self-Administered 24-hour dietary recall (ASA24): a resource for researchers, clinicians, and educators from the National Cancer Institute.
TLDR
The features of ASA24 are described, which include an automated self-administered 24HDR for adults, improved usability and new features, which are expected to be available mid-2012. Expand
Fruit and vegetable assessment: performance of 2 new short instruments and a food frequency questionnaire.
TLDR
Both screeners might be useful to estimate median intakes of fruit and vegetable servings in US populations, but they might be less useful in accurately ranking individuals. Expand
Statistical methods for estimating usual intake of nutrients and foods: a review of the theory.
TLDR
The statistical theory that underlies the four major modeling methods developed to date is described, then the strengths and limitations of each method are reviewed, and the need for an improved method for estimating usual intake distributions for episodically consumed foods is demonstrated. Expand
Dietary Assessment Methodology
TLDR
This chapter reviews major dietary assessment methods, their advantages and disadvantages, and validity; describes which dietary Assessment methods are appropriate for different types of studies and populations; and discusses specific issues that relate to all methods. Expand
