“…In terms of the development of the NANA system, it was concluded that higher accuracy would be achieved by a nutritionist making portion size assessment from a photograph of a meal and this was incorporated into the design of the system (17,18). These results support the recent developments in dietary assessment and technology which have shown that taking the onus of portion size estimation off the individual and putting it on a trained researcher yields accurate results compared to weighed methods of dietary assessment (13,14). However, many of the technological advancements in dietary assessment and portion size estimation have been developed for children and younger adults.…”

“…The use of computerised image analysis to determine the portion size of food from photographs of meals has also been investigated (12)(13)(14). Image analysis offers the potential of automating food recognition alongside volume estimation, which could improve the accuracy of portion size assessment and remove the burden of portion size assessment from the participant.…”

Abstract:Objectives: To investigate the ability of older adults, younger adults and nutritionists to assess portion size using traditional methods versus a computer-based method. This was to inform the development of a novel dietary assessment method for older adults "The NANA system". Design: Older and younger adults assessed the portion size of self-served portions of foods from a buffet style set up using traditional and computerised portion size assessment aids. Nutritionists assessed the portion size of foods from digital photographs using computerised portion size aids. These estimates were compared to known weights of foods using univariate analyses of covariance (ANCOVA). Setting: The University of Sheffield, United Kingdom. Subjects: Forty older adults (aged 65 years and over), 41 younger adults (aged between 18 and 40 years) and 25 nutritionists. Results: There was little difference in the abilities of older and younger adults to assess portion size using both assessment aids with the exception of small pieces morphology. Even though the methods were not directly comparable among the test groups, there was less variability in portion size estimates made by the nutritionists. Conclusion: Older adults and younger adults are similar in their ability to assess food portion size and demonstrate wide variability of estimation compared to the ability of nutritionists to estimate portion size from photographs. The results suggest that the use of photographs of meals consumed for portion size assessment by a nutritionist may improve the accuracy of dietary assessment. Improved portion size assessment aids are required for all age groups.

“…In recent years there have been many advances in the application of technology in the area of dietary assessment (2) . Innovative dietary assessment technologies using devices such as mobile telephones (3)(4)(5)(6)(7)(8) , sensors, wearable cameras (9)(10)(11) and web-based platforms are common ways of collecting dietary intake data and have become increasingly popular alternatives to traditional pen-and-paper versions of dietary assessment (12) . Web-based methodologies facilitate the collection of dietary intake across many geographic locations (13)(14)(15)(16) and in some cases are preferred by participants compared with the traditional pen-and-paper alternatives (3,17) .…”

(24HDR) method is currently the most utilised method for the collection of dietary intake data at a national level. Recently there have been many developments using web-based platforms to collect food intake data using the principles of the 24HDR method. This review identifies web-and computer-based 24HDR tools that have been developed for both children and adult population groups, and examines common design features and the methods used to investigate the performance and validity of these tools. Overall, there is generally good to strong agreement between web-based 24HDR and respective reference measures for intakes of macro-and micronutrients. Embargo lift date
