Summary

Assessment of dietary intake is key for understanding the links between diet and health. Here, researchers will study molecules in urine samples to give 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.

Biomarkers of Fruit and Vegetable Intake

Cross-over study where participants will visit the Human Intervention Centre (in UCD) on 3 occasions (3 study days) with a minimum one week between each visit. The order of consumption of the test foods will be randomized. The test foods are mixed vegetables (spinach and lettuce), green beans and mixed berried (strawberries and blueberries). The following definition of portion sizes will be used; green beans (120g), lettuce (20g), spinach (90g), strawberries (96g) and blueberries (75g). For each study day, the participants will arrive fasting and provide a urine sample (0h sample). For 24h prior to the study day participants will avoid the test foods. Participants will consume the food and urine samples will be taken at 2, 4, 6 and 24 h post consumption.
