Plain English summary of protocol
Background and study aims
Assessment of dietary intake is key to understand the links between diet and health. Here, researchers are going to study molecules in urine and blood samples to that them an insight into what people have eaten. These new molecules are called dietary biomarkers. This study will help to identify new molecules that can act as biomarkers of commonly consumed foods. These can then be used in the assessment of diet, identification of diet-related diseases and used how to explain how a dietary intervention (programme) will work , thereby adding to scientific knowledge.
Who can participate?
Healthy adults between 18-60 with a body mass index (BMI) between 18.5 and 30 kg/m2.
What does the study involve?
Each participant is asked to eat one of each of the following foods at a time, in a random order: broccoli, red bell peppers, oranges, apples, madeira sponge cake, spaghetti, white bread, wholemeal bread and cheddar cheese. They are asked for urine and blood samples for up to 4 hours after eating each food. They are also asked for a fasting blood sample and urine sample one day after eating the foods. The samples are then analysed for dietary biomarkers.
What are the possible benefits and risks of participating?
There are no known benefits or risks to taking part in this study.

| Health condition(s) or problem(s) studied | Dietary biomarkers |
| Intervention | Randomised study where subjects will consume one of the following in random order on one occasion only and samples will be collected following consumption (up to 4 h post consumption): Broccoli, red bell peppers, oranges, apples, madeira sponge cake, spaghetti, white bread, wholemeal bread and cheddar cheese. One day after consumption of the foods a fasting blood and urine sample will also be collected. |
