Background and study aims
Diet has a huge impact on the health and well-being of individuals and is a major contributor to the development of a range of chronic health conditions, such as diabetes, cardiovascular diseases, and many cancers. Many countries are facing rising levels of obesity and diet-related disease due to changes in dietary choices and eating behaviour, as well as more sedentary lifestyles. The robustness and impact of strategies aimed at addressing nutrition-related problems are consistently undermined by misreporting of dietary intake caused by our lack of an accurate tool to assess and monitor dietary intakes. Self-reporting tools used traditionally to capture information about diet include Food Frequency Questionnaires (FFQs), 24-hour dietary recalls and food diaries. These tools struggle to categorise and represent accurately dietary intake and often involve costly expert researcher support, a substantial burden to study/survey participants and are subject to poor compliance, dietary change, and significant reporting bias. To improve dietary reporting, the researchers will bring together three additional technologies which have shown promise in improving accurate reporting of dietary intake. These are urine biomarkers, capillary blood biomarkers and wearable micro cameras. The overall aim of this study is to improve the accuracy of dietary reporting by combining all these tools.
