Brief summary

The AMMEND study is a 3-month randomised control trial testing the effect of a Mediterranean diet (MD) on the symptoms of depression in young men. Participants will be randomly allocated to either the MD group or the control group, which consists of a social support “befriending” protocol, via a computer-generated block randomisation sequence. At the baseline appointment participants will complete a number of questionnaires and baseline measurements which will be recorded in the Case Report Form, including the Becks Depression Inventory depression scale and a short Dietary Screener Questionnaire (DSQ). Participants will have scheduled follow up appointments at 6 weeks and 12 weeks. Participants in the MD group will complete Diet History Forms to check levels of adherence to the diet and will be scored against the MD Adherence Score. The main outcome measure will be any changes to the BDI depression scale results. At the conclusion of the trial, participants in the MD group will complete a short, electronic, self-administered survey assessing their experiences and perceived benefits and challenges of continuing to follow a Mediterranean diet long term.

Interventions

Participants will be allocated to either follow a Mediterranean Diet (MD) or Social support for 12 weeks. Participants will continue with there current medications and/or psychology appointments. A Mediterranean diet is high in wholegrains, fruits and vegetables, legumes, nuts and seeds and plenty of olive oil, it is low in processed or “fast foods” and high sugar snack foods and beverages. Participants in the MD group will follow the diet for all meals and snacks for 12 weeks. Participants will

Participants will be allocated to either follow a Mediterranean Diet (MD) or Social support for 12 weeks. Participants will continue with there current medications and/or psychology appointments. A Mediterranean diet is high in wholegrains, fruits and vegetables, legumes, nuts and seeds and plenty of olive oil, it is low in processed or “fast foods” and high sugar snack foods and beverages. Participants in the MD group will follow the diet for all meals and snacks for 12 weeks. Participants will be provided with a food hamper at the beginning of the trial which included diet staples such as olive oil, nuts and vegetables to get them started and will then buy and cook their own food. They will be provided with comprehensive handouts designed specifically for this study including diet guidelines, meal ideas and example diet plan. The diet will be administered by a qualified nutritionist who participants will meet with at baseline (week 0), week 6 and week 12 for 1 hour. Diet adherence will be monitored by an online food diary (created on surveygizmo for the purpose of this study) which is reported daily.
