- Depression is a mood disorder affecting 3.8% of the world’s population.
- New research from the University of Technology Sydney suggests the Mediterranean diet helps improve depression symptoms in young men.
- Researchers observed an improvement in depression symptoms in all participants provided Mediterranean diet support, with 36% lowering their symptoms to low or minimal depression standards.
Over the past few years, the Mediterranean diet has quickly become the diet du jour. Research shows this way of eating provides a number of positive health impacts, including improving a person’s gut microbiome, reducing

Researchers from the University of Technology Sydney have now found evidence that a Mediterranean diet can also help improve symptoms in young men living with depression.

For instance, one study suggested that men may be more likely than women to manifest depression through feelings of anger or through substance misuse.
According to Jessica Bayes, a doctoral candidate at the University of Technology Sydney, Faculty of Health, and lead author of this study, she and her research team decided to focus on young men ages 18–25 for this study because young men are much less likely to seek help for their mental health.
“We urgently need more effective evidenced-based treatment strategies to help depression that appeal to young men,” she told MNT. “Diet could be a great first step towards recovery.”
Bayes and her team conducted a 12-week randomized control trial with 72 male participants between the ages of 18 and 25 with moderate to severe depression. Participants were randomly selected to either receive dietary support by learning how to eat a Mediterranean diet or
At the end of the study, researchers reported that 100% of participants in the Mediterranean diet support group experienced an improvement in their depression symptoms.
In that group, 36% saw a decline in their Beck Depression Inventory Scale (BDI-II), to a score of 0-10 (low or minimal depression). Whilst there was also a decline in the average score in the befriending group, all of the participants’ scores in the befriending group remained at the level of moderate to severe depression by the end of the trial.
According to Bayes, while previous observational evidence shows a Mediterranean diet is helpful in preventing depression, this was the first study in young men with clinical depression to test the diet in an experimental trial.
“We were surprised by how quickly the positive effects were seen, and how willing the participants were to continue the diet after the trial had finished,” she explained.
“Nearly all our participants stayed with the program, and many were keen to continue the diet once the study ended, which shows how effective, tolerable, and worthwhile they found the intervention.”

MNT also spoke with Dr. David A. Merrill, psychiatrist and director of the Pacific Neuroscience Institute’s Pacific Brain Health Center at Providence Saint John’s Health Center in Santa Monica, CA, who was very excited about the results of this study.
Dr. Merrill said the Mediterranean diet provides a bio-psycho-social model for treating depression. “Men tend to have poor diets in general and tend to work towards having convenient fast foods that are nutritionally poor or sub-optimal,” he explained.
“This sort of nutrition intervention addresses biology — it can improve micronutrient status for individuals, things like […] pro-cognitive, pro-mood supporting elements [and] proteins that are precursors for neurotransmitters like serotonin.”
“It [also tends] to have a social component […] in terms of preparation, food invites collaboration, like a partnership with family members, loved ones, cooks, chefs, which becomes a social boost.”
“One of the reasons the Mediterranean style diet can be one of the most effective nutrition interventions is that people tend to stick with it at higher rates,” he said.
“People tend to stop doing [limitation diets] once they’re out of a structured trial. It really is true that food needs to be enjoyable, sustaining, and social. Luckily, the Mediterranean diet fits all that and is very nutritious as well.”
