Methods to Determine Dietary Intake

Challenges in Estimating Dietary Acrylamide Intake

“…However, if the goal is to estimate only the mean intake of a population (e.g., for calibration purposes), then one 24-HR or food record is sufficient provided that all days of the week and months of the year are equally represented across a sufficiently large sample [6]. However, a sufficiently large sample size of several thousand individuals covering equally all days of the week and all seasons of the year is needed.…”

“…Both types of errors can occur at individual level (within-person) and group/population level (between-persons) [6,7]. Both types of errors can occur at individual level (within-person) and group/population level (between-persons) [6,7].…”

“…Information should be collected from each individual of a study sample with the best available measurement tools or techniques in a standardized way and with as many replicates as necessary and feasible [6,7]. Information should be collected from each individual of a study sample with the best available measurement tools or techniques in a standardized way and with as many replicates as necessary and feasible [6,7].…”

“…Second, because dietary acrylamide intake estimates, like any measurement, can still contain substantial error, it is thus also important to quantify the overall magnitude of both random and systematic errors in evaluation studies and how the measurement errors affect the results of the main study [6].…”

“…In public health nutrition research studies, dietary acrylamide intake is usually assessed through estimates based on self-reported dietary consumption of known acrylamidecontaining foods, typically by means of short-term instruments such as 24-h dietary recalls or long-term instruments such as food frequency questionnaires (FFQ) [6,7].…”
