“…In the clinical practice setting, variables that impact the assessment method selected include the nutrient (macronutrient versus micronutrient), patient diagnosis, inpatient versus community setting, and the level of precision required. Frequently, a compromise is made between the most precise methods of dietary assessment (e.g., intensive use of biomarkers and weighed food records for a long study duration), the logistics (e.g., sample size, cost, geography), and the respondent burden or intensity of measurements that the study population will tolerate (Seaman, 1995).…”

Diet may play a significant role in cancer prevention, disease progression, and treatment tolerance. An in-depth search of the literature revealed limited information geared toward nurses about diet assessment methods used in research. The purpose of this review is to synthesize the evidence regarding diet assessment methods important in oncology studies. The method used varied based on the study size, duration, and research question. For example, studies focusing on mean nutrient intake of a group used a 24-hour dietary recall, estimated food diary or dietary record, or food frequency questionnaire. Studies investigating usual nutrient intake predominately used multiple 24-hour dietary recalls, dietary records, biomarkers, or food frequency questionnaires. Measuring dietary intake accurately in a cost-effective manner is a difficult task. Selection of the appropriate assessment tool is critical for the generation of quality data. Oncology nurses are increasing their involvement in nutrition research, and the findings from this review may promote a better understanding of the published and ongoing research in this important field of study.

“…Dietary records are kept for a predetermined period, which usually is 3-14 days. The recommended length of study duration varies for each vitamin, mineral, and macronutrient (Seaman, 1995;Willett, 1990;Wylie-Rosett et al, 1990). Food portion sizes may be estimated using household measures, photographs, or food models.…”

A method was developed to determine the levels of two intense sweeteners, saccharin and acesulfame-K, in human urine. Measurement of these two analytes in urine allowed an assessment to be made of dietary exposure to the sweeteners using intake/excretion curves. This paper describes an intake/excretion study in which 22 volunteers consumed known amounts of saccharin and acesulfame-K at five different levels ranging between 1.4 and 70 mg of saccharin (0.7-30% of the ADI for a 60 kg person) and 2.2-102 mg of acesulfame-K (0.4-19% of the ADI for a 60 kg person). Urine collections were then carried out by the volunteers for 24 h after each dose. The data obtained from this study were used to construct intake/excretion curves for both sweeteners. To test the methodology developed, 188 volunteers aged between 3 and 74 years were asked to carry out a 24-h urine collection whilst keeping a 48-h food diary. Comparison of the intake data obtained using the biomarker approach with the questionnaire-based results was generally good, although discrepancies due to the format and assessment of the questionnaire data were noticed.
