What is dietary recall?
A dietary recall is a method of dietary assessment based on a face-to-face interview conducted by specifically trained personnel. During the interview, an individual is asked to recall their food and beverage consumption during the previous day.
Online 24-hour dietary recall. Under 20 minutes average completion time. High tolerance to spelling mistakes. Accurate image-based portion size estimation. Automated coding to nutrient data. Instant availability of nutrient reports.
Over 2800 foods with carefully selected automated portion size estimation methods. More than 2500 portion size images which have been extensively validated in a feeding study and against 4-day weighed diaries.
Data are output in spreadsheet format for easy manipulation and analysis. Nutrient intake can be output as soon as the participant has finished entering their data. Data output includes food groups, energy, macro- and micronutrients.
Newcastle University conducted a comparison of Intake24 with interviewer-led recalls was conducted in 180 people. Intake24 was found to under-estimate energy intake by just 1% on average. Mean intakes of all macronutrients and micronutrients (except non-milk extrinsic sugars) were within 4% of the interviewer-led recall.
