DESCRIPTION OF THE DATA:
This cross-sectional data was collected via an online research participant platform Prolific. The group with depression was collected from a sample previously screened for self-reported depression diagnoses by a project run within the Centre for Innovation in Mental Health (ERGO ID: 64381). This was based on participants reporting a depression diagnosed by mental health professional. The healthy control group was recruited from the overall sample using a filter to screen for individuals without a self-reported mental health problem. Participants were directed from Prolific to the web-based online survey tool Qualtrics via link. They were asked to provide demographic information including age, gender, and ethnicity, and were asked about alcohol, antidepressant, and supplement consumption. Participants then completed the self-report measures on their dietary intake(fruit and vegeytables, omega-3 foods, probiotic foods), physical activity, gastrointestinal health, and mental health (depression).
