“…These results indicate that there likely remains some error with eating events that are never photographed or remembered, which may be attributed to the inherent inaccuracy of self-reported dietary recall. This problem may be mitigated by sending reminder text messages to participants to photograph their foods [ 35 ]. Short messaging service (SMS) text messaging has been used successfully to improve compliance with medication and appointments [ 36 , 37 ] as well as to promote healthy behavior for weight maintenance [ 38 , 39 ].…”

BACKGROUND/OBJECTIVESThe Recaller app was developed to help individuals record their food intakes. This pilot study evaluated the usability of this new food picture application (app), which operates on a smartphone with an embedded camera and Internet capability.SUBJECTS/METHODSAdults aged 19 to 28 years (23 males and 22 females) were assigned to use the Recaller app on six designated, nonconsecutive days in order to capture an image of each meal and snack before and after eating. The images were automatically time-stamped and uploaded by the app to the Recaller website. A trained nutritionist administered a 24-hour dietary recall interview 1 day after food images were taken. Participants' opinions of the Recaller app and its usability were determined by a follow-up survey. As an evaluation indicator of usability, the number of images taken was analyzed and multivariate Poisson regression used to model the factors determining the number of images sent.RESULTSA total of 3,315 food images were uploaded throughout the study period. The median number of images taken per day was nine for males and 13 for females. The survey showed that the Recaller app was easy to use, and 50% of the participants would consider using the app daily. Predictors of a higher number of images were as follows: greater interval (hours) between the first and last food images sent, weekend, and female.CONCLUSIONSThe results of this pilot study provide valuable information for understanding the usability of the Recaller smartphone food picture app as well as other similarly designed apps. This study provides a model for assisting nutrition educators in their collection of food intake information by using tools available on smartphones. This innovative approach has the potential to improve recall of foods eaten and monitoring of dietary intake in nutritional studies.

“…Text messaging and food photography have been shown to make dietary intake easier and more acceptable for athletes. 27 Thus, the RD instructed them in the use of MealLogger, a photo journaling application that facilitates tracking calorie, carbohydrates, and protein for each meal. 28 They agree to network their records with the RD.…”

“…Photographic food records typically contain two images, a pre-and post-ingestion photograph of the meal, taken by the participant at the correct distance, angle, and observing any other instructions to obtain clear photographs, such as cutting sandwiches in half to display fillings clearly or including a fiducial marker in the image as a size marker (6,7). Though photographic food records have been shown to reduce participant burden in comparison to written diet diaries (4,7,8), there are still challenges associated with them, such as being able to identify specific food brands, nutritional claims (e.g., fat free, low sodium), and preparation methods in pre-and post-ingestion images with no other visible details (9). Passive capture methods may overcome some of these challenges by capturing multiple images at predetermined time intervals, without any action from the participant (10)(11)(12)(13)(14).…”

ObjectiveTo describe best practices for manual nutritional analyses of data from passive capture wearable devices in free-living conditions.Method18 participants (10 female) with a mean age of 45 ± 10 years and mean BMI of 34.2 ± 4.6 kg/m2 consumed usual diet for 3 days in a free-living environment while wearing an automated passive capture device. This wearable device facilitates capture of images without manual input from the user. Data from the first nine participants were used by two trained nutritionists to identify sources contributing to inter-nutritionist variance in nutritional analyses. The nutritionists implemented best practices to mitigate these sources of variance in the next nine participants. The three best practices to reduce variance in analysis of energy intake (EI) estimation were: (1) a priori standardized food selection, (2) standardized nutrient database selection, and (3) increased number of images captured around eating episodes.ResultsInter-rater repeatability for EI, using intraclass correlation coefficient (ICC), improved by 0.39 from pre-best practices to post-best practices (0.14 vs 0.85, 95% CI, respectively), Bland–Altman analysis indicated strongly improved agreement between nutritionists for limits of agreement (LOA) post-best practices.ConclusionSignificant improvement of ICC and LOA for estimation of EI following implementation of best practices demonstrates that these practices improve the reproducibility of dietary analysis from passive capture device images in free-living environments.
