Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
During the study day, participants will attend the research facility after an overnight fast and provide a fasted urine sample. Participants will also be asked to avoid coffee/coffee products for 10 hours prior to collection of this fasting urine sample. Following this, participants will be given a coffee to drink (4 g instant coffee in 150 mL hot water) by a dietitian or trained researcher. Participants will then continue collecting their own urine for the next 24 hours, into provided containers. Participants are also asked to consume no more coffee during those 24 hours, but can otherwise eat and drink ad libitum. Participants returned their collected urine the following morning.
