Mediterranean diet linked to improved mental health in adults over 50

A study published in the scientific journal Nutrients suggests that adherence to a Mediterranean diet is linked to better mental well-being, particularly in individuals over the age of 50.

Researchers analyzed data from more than 3,200 men and women aged 50 to 90 living in England. The study assessed dietary habits, mental well-being, quality of life, and depressive symptoms. Findings indicated that those who more strictly followed the Mediterranean diet exhibited higher levels of mental well-being compared to those with lower adherence. This correlation remained significant even after accounting for factors such as age, gender, physical activity, smoking, chronic illnesses, and existing depressive symptoms.

The research also observed that participants following this dietary pattern experienced less decline in mental health during the initial months of the COVID-19 pandemic. Experts suggest the benefits may stem from the diet's high content of antioxidants, fiber, and healthy fats found in fruits, vegetables, legumes, whole grains, olive oil, fish, and nuts. Additionally, fermented foods like yogurt may support mental health through the gut-brain axis.
