Three possible causes of this misperception have been tested by questionnaire in this study: the greater number of pieces of thin chips may suggest that there is a greater amount or they might match the height of the mound or the plate coverage. Subjects plated three

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 ...
