The mobile telephone food record (mpFR) is a unique dietary assessment tool in development. The user records foods and beverages in images taken before and after eating. The images can be used for automated food identification and portion size estimation. The objective of this study was to compare reported energy intake (rEI) from 3 non‐consecutive days of mpFR use to Estimated Energy Requirements (EER). Twelve adults (aged 20–58 y. 5 women, 7 men) were recruited from the campus community. All meals and snacks of known portions were provided to participants in excess of their EER. On 2 days, participants consumed all foods and beverages in their free‐living environment. For one day, all meals were consumed in the research facility and the provided snacks were eaten in their free‐living environment. The participants received training on using the mpFR installed on iPhone 3Gs. Participants were asked to capture images of all meals and snacks on each day. Images taken by the participant were reviewed by research staff and portions of foods and beverages in each image were estimated. The mean difference between the average rEI and EER was −348 kcal (SE 227). There was no significant difference between the mean rEI across recording days and EER ( p = 0.155). These results reinforce the use of image based dietary assessment in the clinical and research setting leading to more accurate accounts of dietary intake. Grant Funding Source: NIH: NCI, NIDDK
