Introduction
Dietary assessment is crucial for advancing nutritional studies and promoting public health. It is a fundamental tool for assessing nutritional adequateness, eating patterns, and the connection between diet and health consequences. Researchers and medical professionals may develop customized dietary recommendations, make well-informed judgments, and build successful treatments to address a range of health issues with the help of accurate nutritional evaluation. It is essential to evaluate the techniques of recalling dietary intake within a 24-hour period and maintaining a weighted record of dietary intake for a week.
Evaluating food consumption is essential for public health and personal health. Domenech-Briz et al. (2023) shows that knowing what and how much one eats may help inform individualized dietary advice and offer insightful information about one’s nutritional habits. It helps identify overconsumption or dietary deficits, empowering people to make decisions to improve their health.
Bamji (2019) shows that dietary evaluations assist in creating evidence-based recommendations and programs in the field of public health. They support identifying healthy trends and patterns within communities, which aids in managing and preventing illnesses linked to nutrition. In addition, they facilitate the investigation of the correlation between nutrition and health effects by researchers. It helps to develop approaches to mitigate the worldwide prevalence of non-communicable illnesses.
Background
There are two ways to collect food intake data for the two dietary evaluation methodologies: the 24-hour recall and the 7-day weighted record. In the 24-hour recall, participants provide a comprehensive account of their diet by recalling the entirety of their food and drink intake in the preceding 24 hours. (Huang et al, 2022b). Given its simplicity and minimal demands on participants, it is a logical alternative for extensive research. Alternatively, according to Huang et al. (2022a), the 7-day weighted record gives a more thorough depiction of dietary patterns by having participants weigh and record each item they eat over a week. Although this approach requires more work from participants, it offers a solid dataset for in-depth examination.
Methodology
In this context, three diabetic patients aged 30 to 50 years will be selected as participants. Individuals will systematically provide information on their dietary intake as part of the approach that requires them to remember and report their food consumption from the past 24 hours. Each participant will be given a detailed interview during which they are asked to recall everything they ate and drank in the previous 24 hours. Every detail, including portion proportions and preparation techniques, will be documented. The primary purpose of conducting a 24-hour recall is to gather information about an individual’s eating habits, encompassing their nutritional intake and dietary preferences.
In the 7-day weighed record method, the three selected participants will weigh and record every food and beverage they ingest for a week. It will entail calculating serving amounts and recording cooking techniques. A 7-day weighted record showing nutrient consumption and long-term eating habits will accurately and entirely represent a person’s nutritional intake. It is valuable for understanding the dietary habits of diabetic patients, helping to evaluate their nutritional needs, and inform tailored interventions. Ethical considerations include confidentiality, informed consent, participant autonomy, and minimizing potential psychological distress, which are essential when conducting dietary evaluations among diabetic patients.
Strengths and Limitations
As methods of assessing nutrition, the recall of food consumed in 24 hours and the record of food intake over seven days have advantages. The 24-hour recall is an excellent method for large-scale research because it is easy to use and minimizes stress for participants, especially in clinical and public health settings (Huang et al., 2022a). It briefly summarizes current eating patterns, making it helpful in detecting temporary changes. The 7-day weighted record, on the other hand, is highly regarded for its accuracy and depth of information (Huang et al., 2022b).
As a gold standard for validation studies and a record of food habits across time, it helps conduct in-depth investigations. However, as a result of its comprehensive nature, it requires a higher commitment from participants and may be subject to underreporting. The choice between these methodologies should coincide with the study aims, the resources available, and the desired level of detail in dietary data analysis.
The seven-day weighted record and the 24-hour recall both have drawbacks and possible sources of bias. Huang et al. (2022b) show that the 24-hour recall depends on participant recollection and is subject to recall bias. Therefore, participants may report their intake of food and beverages incorrectly or forgetfully. Furthermore, this approach can not account for daily fluctuations in food consumption, which could result in an inaccurate picture of a person’s diet. Social desirability bias can affect both approaches, causing participants to underreport or alter their food choices to show themselves favorably, thus biased the results.
However, although more thorough, the 7-day weighted record necessitates a high level of participant engagement and exacting weighing and recording. It can be laborious and time-consuming and result in missing or erroneous data (Huang et al., 2022a). Measurement mistakes can include inaccurate food weighing, estimation of portions, and omission of certain items, which can further distort nutritional data. Therefore, while evaluating the data and planning nutritional assessment studies, researchers must be mindful of these limitations and possible causes of bias.
Analysis of Dietary Intake Data
Data on food consumption can be analyzed using many essential methods, focusing on specific nutrients. The dietary records’ correctness and completeness are checked after data collection. It is standard procedure to convert portion quantities into standardized units. The macronutrient composition (fat, protein, and carbohydrates) determines the energy consumed. The distribution of macronutrients may be ascertained by evaluating each of these macronutrients to the overall amount of energy consumed. The estimation of fiber intake involves the identification and quantification of its dietary sources. By comparing the dietary items recorded with nutritional databases or software, it is possible to examine the levels of micronutrients such as iron, calcium, and vitamin C and calculate daily intakes. A thorough study provides information on nutrient intake, identifies excesses or deficiencies, supports the evaluation of dietary sufficiency, and directs the advice of a balanced diet.
Results

Discussion
Some noteworthy trends and conclusions are shown by analyzing the nutritional intake data collected using the 24-hour recall and the 7-day weighted record techniques. Table 1 shows the results of six participants during the nutritional intervention. Compared to the 24-hour recall, the 7-day weighted record approach produced lower energy consumption, protein, fat, and carbs estimates among the six diabetes participants. It could be due to the detailed weighing record, which could result in better accuracy and a more cautious consumption estimate. Furthermore, there are differences in the patients’ consumption levels of fiber and micronutrients, including iron, calcium, and vitamin C, which may be related to personal dietary choices and practices.
Dietary habits can be misrepresented when underreporting, memory bias, and inaccurate measurements are present. Errors in quantifying food consumption can seriously impact the reliability of nutritional studies and guidelines. Due to its ease of use and minimal participant burden, the 24-hour recall may help capture immediate eating habits. However, Huang et al. (2022a) indicate a potential increase in susceptibility to recall bias and insufficient reporting, potentially leading to an overestimation of nutrient consumption.
Conversely, due to its detailed nature and the possibility of participant burden, Huang et al. (2022b) show the 7-day weighted record’s accuracy and thorough data collection might result in lower calorie and nutritional intake approximations. Variations in fiber and micronutrient consumption indicate the approach’s limitations in capturing long-term dietary habits. Interpreting these findings stresses the significance of method considerations in dietary assessment, acknowledging their substantial influence on data reliability.
Conclusion
By contrasting the two dietary evaluation techniques, one can better understand their advantages and disadvantages. The 24-hour recall provides a convenient overview of a person’s diet in a short duration, but it may be more prone to memory bias and inadequate reporting. However, there may be a compromise between accuracy and participant burden with the 7-day weighted record. Thus, it might result in lower approximations of calorie and nutrient consumption. This understanding is vital for improving data quality and making dietary assessments more reliable in research and public health applications.
