A recent study published in the Nature Mental Health journal has shed light on the potential benefits of consuming a Mediterranean diet, rich in fruits, vegetables, and fish, in reducing symptoms of post-traumatic stress disorder (PTSD).
Researchers examined the relationship between trauma exposure, PTSD symptoms, gut microbiome, and dietary habits among 191 women participating in a smaller research project within a broader women’s health study.
The study’s findings revealed a significant correlation: higher levels of PTSD symptoms were associated with lower adherence to the Mediterranean diet pattern. Furthermore, this association was linked to specific gut bacteria, including the beneficial species Eubacterium eligens.
Of the study participants, 44 women reported experiencing PTSD symptoms, 119 had a history of trauma but did not exhibit PTSD symptoms, while 28 had neither. This data highlighted the potential influence of diet on PTSD symptoms.
The research suggested that women who followed a Mediterranean diet experienced fewer PTSD symptoms. In addition, the consumption of plant-based foods was positively associated with a lower prevalence of PTSD symptoms, while a higher intake of red and processed meats correlated with an increased occurrence of symptoms.
Carol Shively, a pathology professor at Wake Forest University School of Medicine, emphasized the practical implications of the study. She indicated that the findings could provide dietary recommendations for individuals at risk of developing PTSD, especially those in professions where they might face traumatic experiences, such as the military.
Shively explained that adhering to a Mediterranean diet might mitigate the harmful stress responses triggered by traumatic events, thereby offering a potential means of support and resilience.
Co-corresponding author Karestan Koenen, a professor of psychiatric epidemiology at the Harvard Chan School, highlighted the significance of examining the gut-brain axis and its potential role in understanding the interplay between mental and physical health. This research area holds promise for future recommendations aimed at alleviating the adverse health consequences of PTSD.
The study’s author, Yang-Yu Liu, a statistical physicist at Brigham and Women’s Hospital, expressed excitement about the implications of the research. The findings suggest that a Mediterranean diet may offer relief to individuals experiencing PTSD symptoms. Future studies are expected to further explore the complex relationship between PTSD, diet, and the gut microbiome, with particular attention to the potential use of probiotics as a preventive measure against PTSD.
In summary, this study underscores the potential impact of dietary choices on mental health and the management of PTSD symptoms, offering new avenues for intervention and support.
