Brand Level Nutrient Information Compared to Generic Food Codes

Brand Level Nutrient Information Compared to Generic Food Codes: Impact on Results From Dietary Recalls

Measuring diet is difficult. This is the first time that brand level foods and nutrient values have been compared with generic food codes to explore the difference this might make to estimated nutrient intakes.

Study Overview

• Status: Completed
• Conditions: Diet Surveys; Diet Records
• Intervention / Treatment: Other: no intervention - recoding of food recall only

Detailed Description

Background Traditional dietary assessment methods lack precision. myfood24 is an online 24-hour dietary assessment tool, aiming to reduce the burden of dietary assessment; providing data entry by participants using automated coding of food items. myfood24 includes a large branded food database.

Objective To assess the effect of using brand level nutrient information compared to generic food codes on estimated nutrient intakes.

Design A 24 hour recall was collected using myfood24, which contains a food and nutrient database of over 40,000 items with both branded and generic foods. Participants freely selected their foods generating the 'free choice recall'. After the online recall was completed, they provided further details of brands consumed. The free choice recalls were recoded forming an 'all branded' and an 'all generic' recall. Estimated nutrient intakes from the three different methods of food coding were compared to assess the impact of brand-level information.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Food code group; The participants freely selected foods from the online dietary assessment tool to record what they had eaten over the last 24h. They then provided information on brand details. The recalls were recoded to take into account all branded items and then recoded again to take represent all generic (ie. no brands) foods.	Other: no intervention - recoding of food recall only; recoding of food recall
