Plain English summary of protocol
Background and study aims
Unhealthy diets are associated with metabolic changes and increased risk of non-communicable diseases (NCDs). However, current understanding of the relationship between diet and the development of NCD is limited by a number of factors. These include a lack of understanding of dietary mechanisms that drive NCD, inaccurate tools to collect dietary information, a nascent understanding of the role of personalised nutrition, and the lack of data in vulnerable groups where NCDs are often over-represented.
The relationship between dietary intake and the development of NCD is complex. The understanding of how diet relates to the development of metabolic risk factors on a background of non-modifiable risk factors is improving with the greater understanding of the metabolic pathways that are responsive to dietary profile and lead to change in NCD risk. Tools that profile the genome, metabolome, epigenome, microbiome, and inflammation are key to understanding the impact of diet on NCDs. However, these systems are mostly studied in isolation and their relative importance of how they interact with each other is not understood.
Who can participate?
Healthy volunteers (male and female), aged 18-65 years old, with BMI over 25 kg/m² and two other risk factors.
What does the study involve?
Participants will need to wear a micro-camera that tracks their dietary intake and a wristband that measures their physical activity and sleeping patterns for seven days each on three separate occasions. In addition, while the volunteers are wearing the camera and the wristband, they will need to complete a five-day food diary online. At the end of the first and third period of wearing the devices and completing the food diaries, the volunteers will be asked to attend two studies, where they will have their body composition and general health assessed, provide blood, stool, breath, and urine samples. In addition, during these two study visits and only at the Imperial College London site, the volunteers will be asked to undergo a mixed meal tolerance test where the participants will consume a standard meal and then have blood samples taken over a six hours period.
At the end of the second period of wearing the devices and completing the food diaries, the volunteers will be asked to attend a 30-minutes study visit where they will only have their body composition and general health assessed (no biofluids will be taken). After the volunteers have completed all study visits, they will be asked to complete short questionnaires through which they will be able to express their views on participating in the study.
What are the possible benefits and risks of participating?
Participants will receive £200 upon completion of the study to reimburse them for the time they have taken to attend study visits.

| Scientific title | Combatting Diet Related Non-Communicable Diseases through Enhanced Surveillance |
| Study acronym | CoDiet |
| Study objectives | Integrating multiple methods of assessing dietary intake (micro-camera technology and online food diaries) with collection and analysis of a wide range of bio fluids (blood, urine, faeces and breath) and with non-invasive body composition measurements can help understand better the relationship between dietary intake and risk of non-communicable diseases. |
