According to the International Dietary Data Expansion (INDDEX) Project, weighed food records (WFR) provide the most accurate quantitative data on individual food intake and are therefore often regarded as the primary "gold standard" in dietary assessment. However, a true single gold standard is elusive due to the inherent trade-offs between accuracy, participant burden, and cost.

According to the National Cancer Institute, a 24-hour dietary recall usually requires 20 to 60 minutes to complete, though the total process can be significantly longer when including preparation, data entry, and analysis. The time commitment for a 24-hour recall depends on several factors, including the method used and the complexity of the reported diet.
