Portion size estimation aids for Asian foods
Journal of Human Nutrition and Dietetics, 2012AbstractBackground: Portion size estimation is fundamental to the accuracy of dietary recall, as well as interventions in obesity. Data on portion size estimation aids (PSEA) for Asian foods are limited. PSEA for Asian foods were developed and their accuracy and precision were tested for inclusion in a food atlas.Methods: Sixteen food items were ...

Portion size estimation and expectation of accuracy
Journal of Food Composition and Analysis, 2006Abstract The accuracy of portion size estimates is critical in dietary assessment. The objectives of this study were to determine the magnitude and direction of error in estimating food amounts using computer-based portion anchors; to compare errors between use of computer- and poster-displayed anchors; and to assess level of accuracy that can ...

AbstractA barrier to controlling the amount of food consumed may be the difficulty consumers have in accurately estimating portion sizes. Although portion size measurement aids (PSMAs) can improve estimation accuracy, their bulk and/or cost tends to make them impractical for regular use.

Validation of a Method for the Estimation of Food Portion Size
Epidemiology, 1992In the context of the planning phase of a large cohort study on dietary habits and cancer, we have developed a food frequency questionnaire on usual food intake, which includes a set of pictures to estimate the portion size of 23 different dishes. The validity of the estimation of portion size of recently consumed foods has been questioned by other ...

Estimation of food portion sizes: Effectiveness of training
Journal of the American Dietetic Association, 1988This study compared the effectiveness of two types of training on the ability to estimate food portion sizes. Training consisted of a 10-minute group session in which subjects practiced measuring various solid and liquid foods with household measures. A second group of subjects viewed food models of solids and liquids.

Influence of energy density and unit size on portion size estimation
Appetite, 2012Consumption of large portion sizes has been associated with positive energy balance and in the long-term, obesity. How much is appropriate to consume may be overestimated for energy dense foods and for snacks/meals containing multiple items. This study tested the hypothesis that energy density (ED), unit size and meal type influences portion size ...

Food models for portion size estimation of
BackgroundNovel portion size estimation aids relevant to the cognitive potential of children are necessary for an improved accuracy in dietary recall. We developed graduated realistic food models for Asian foods and tested their accuracy and precision in children.MethodsFood models were constructed for nine commonly consumed food items using a range of

Comparison of digital photography to weighed and visual estimation of portion sizes
Journal of the American Dietetic Association, 2003The primary goal was to test the validity of digital photography for measuring food portion sizes compared with weighed foods and with direct visual estimation.A total of 60 test meals consisting of 10 different portion sizes from six different university cafeteria menus were prepared and weighed.Food selections and plate waste, as estimated by digital
