Fruit and vegetable intake: Issues with definition and measurement
Open accessAbstract
Accurate determination of fruit and vegetable consumption is essential for research that seeks to determine current fruit and vegetable intake patterns, what type and amount of fruit and vegetable consumption is optimal for human health and for evaluating interventions developed to increase such consumption. However, there are many issues that make accurate determination of fruit and vegetable consumption quite difficult. There are many methods used to measure fruit and vegetable intake, but all have limitations. Also, what foods individuals consider to be or to not be fruits or vegetables appear to be quite variable, with such variability often associated with the individual's racial/ethnic background. Researchers and governmental agencies vary with respect to what foods they include and do not include when calculating fruit and vegetable intake. These differences make it difficult to conduct, evaluate and compare studies in this area. The current paper reviews some of the major issues with measuring and determining fruit and vegetable intake.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
