Researchers from the University of the Sunshine Coast and the University of South Australia have discovered in a recent study that following a Mediterranean diet is linked to lower severity of anxiety and stress-related symptoms in older Australians living in the community. Despite this, there was no observed connection with depressive symptoms. The study also found that specific components of the Mediterranean diet, such as reduced consumption of sugary beverages and increased intake of fruits, nuts, and legumes, were independently associated with lower levels of anxiety symptoms.
The Mediterranean diet is inversely associated with the severity of anxiety and stress-related symptoms.
Anthony Villani, a researcher from the University of the Sunshine Coast, and his team investigated the correlation between adherence to a Mediterranean diet and the severity of depression, anxiety, and stress-related symptoms in older adults. A total of 294 older adults with an average age of 70.4 years who lived independently in Australia participated in the study.
The results showed that adherence to the Mediterranean diet was associated with lower levels of anxiety and stress-related symptoms, but not depressive symptoms. Furthermore, specific dietary components like low intake of fruits, nuts, legumes, and sugar-sweetened beverages were linked to decreased severity of anxiety and stress-related symptoms.
Dr. Anthony Villani noted, “These foods were key indicators in a study of more than 300 older Australians.” Additionally, he mentioned that individuals following a Mediterranean-style diet high in fruits, vegetables, legumes, nuts, seeds, fish, and olive oil had lower intensity of anxiety symptoms.
He continued, “Higher consumption of legumes and nuts, along with lower intake of sugary beverages, showed the most significant impact on reducing anxiety and stress. Nuts and legumes are rich in fiber, healthy fats, and antioxidants, which can have positive effects on brain health through gut health and inflammation reduction.”
The study, which controlled for various factors associated with poor mental health, emphasized the importance of a healthy diet in maintaining good mental health. It also highlighted the need for further research to explore the mental health benefits of the Mediterranean diet in older adults.
Published in Nutrients, the findings of the study are significant for understanding the relationship between diet and mental health in older populations.
