Technology-based methods of dietary assessment: recent developments and considerations for clinical practice

Abstract

Evidence supporting the emerging role of technology-based methods for dietary assessment is growing. As technological advances move rapidly forward it is important to consider a theoretical foundation to help guide the translation of these innovations into routine use in clinical practice.

Food Portion Estimation by Children with Obesity: The Effects of Estimation Method and Food Type

“…Finally, there remained a high degree of error in children's ability to accurately estimate portions from perception. This underscores the limitations inherent in reporting dietary intake data from memory and supports the application of innovative technologies (eg, smart phones) that may be able to minimize this type of reporting error (24).…”

Dietary assessment methods in epidemiologic studies

“…Most state-of-the-art technologies must give enormous potentials to be adapted as a major dietary assessment tool in various epidemiological studies to the conservative open-ended methods depending on paper and pencil surveys [19,20,24,32,33]. Table 2 summarizes the strengths and limitations of dietary assessment methods with newer techniques.…”

“…Software development and the required hardware need high costs in the early stage of the research. However, only if they are prepared, DRs and 24HRs with innovative technologies may reduce their costs and resources for organizing study as well as collecting and handling data, improve consistency of data, collect data in real time and calculate dietary intakes automatically, and allow respondents to focus on dietary assessment [20,23,25,32,33]. While the feasibility of multiple 24HRs and DRs in epidemiological studies has considerably improved with the help of these new technologies, there are still some limitations.…”

Dietary biomarkers: advances, limitations and future directions

“…A FFQ may provide a glimpse into a population’s habitual dietary intake over time, whereas food records and dietary recalls assess days/weeks, which may be more precise but not representative of typical intake over time [4]. Additionally, several technological advances in dietary assessment methods have occurred over the past few years, specifically with computer software and web-based applications [7]. The Nutrition Data System for Research, developed by the University of Minnesota, is a commonly utilized software program that allows for interview-administered 24 hour dietary recalls as well as researcher-entered multiple day food records [8].…”

“…The Nutrition Data System for Research, developed by the University of Minnesota, is a commonly utilized software program that allows for interview-administered 24 hour dietary recalls as well as researcher-entered multiple day food records [8]. The automated multiple-pass method is a 24-hour dietary intake assessment method that is automated but still interview administered [7]. Most recently, the automated self-administered 24-hour dietary recall (ASA24) has been developed and based off of the automated multiple-pass method.…”
