Validity of Individual Portion Size Estimates in a Food Frequency Questionnaire
International Journal of Epidemiology, 1994Dietary surveys often rely upon subjects' ability to estimate their portion sizes instead of weighing them, but information on the validity of such estimates is lacking. This study investigated the validity of estimated portion sizes from a self-administered food frequency questionnaire including photos.Validity was evaluated by comparison with portion

A New Portion Size Estimation Aid for Wedge-Shaped Foods
Journal of the American Dietetic Association, 2006Dietary surveys are important for understanding food consumption patterns in national studies, clinical research, and patient counseling. Portion size estimation aids usually increase accuracy of consumers' reports of the amount of food they ate in dietary surveys. However, wedge-shaped foods (eg, pie, cake, and pizza) pose special problems; this shape

Journal of Human Nutrition and Dietetics, 2003
AbstractBackground Food Photographs and standard portion sizes have been used with adults to assess portion size when recording dietary intake. The effectiveness of these methods may be reduced when memory/recall is required and children may have problems using these techniques.Methods Adults (47) and children (37) were recruited from amongst ...

Topics in Clinical Nutrition, 2017
This study examined the impact of an intervention designed to teach young adults appropriate portion sizes for savory/sweet snack foods using hand gestures, such as handfuls, as portion size estimation aids. Results indicate that participants who received the intervention, relative to those who did not, became much more accurate in their ability to ...

Accuracy of Food Portion Size Estimations By Bulimic Subjects
Journal of the American Dietetic Association, 1995Abstract Dietary assessment is an integral component of the determination of medical, nutritional and educational needs of bulimic individuals. The ability to accurately assess portion size is an important aspect of dietary assessment, but may be altered in bulimics due to changes in visual perception and food beliefs.

Journal of the American Dietetic Association, 1989
Students in a large introductory nutrition course were divided into two groups, one that received training on estimating food quantities and one that received no instruction. Training consisted of 10-minute sessions in which 76 subjects (in groups of 10) passed around and viewed food models labeled with their portion sizes while one of the ...

Improving accuracy of portion‐size estimations through a stimulus equivalence paradigm
Journal of Applied Behavior Analysis, 2014The prevalence of obesity continues to increase in the United States (Gordon‐Larsen, The, & Adair, 2010). Obesity can be attributed, in part, to overconsumption of energy‐dense foods. Given that overeating plays a role in the development of obesity, interventions that teach individuals to identify and consume appropriate portion sizes are warranted.

Evaluation of a Food Portion Size Estimation Interface for a Varying Literacy Population
Proceedings of the 2016 CHI Conference on Human Factors in Computing Systems, 2016Portion size estimation is important for managing dietary intake in many chronic conditions. We conducted a 6-week field study with nine varying literacy dialysis patients to explore the usability and feasibility of a dietary intake mobile application that emphasizes portion size estimation.
