Mediterranean Diet Boosts Psychological Well-Being for Adults Over 50
A longitudinal study of 3,296 English adults aged 50–90 finds that higher adherence to a Mediterranean diet is linked to greater positive psychological well-being across autonomy, self-realization, pleasure, and purpose, independent of depressive symptoms or socio-economic status. During the COVID-19 lockdowns, those with strong Mediterranean-diet adherence experienced a smaller decline in well-being, suggesting the diet acts as a mental-health buffer in times of crisis. Possible mechanisms include anti-inflammatory components (polyphenols, omega-3, fiber) that support gut-brain health and neuroplasticity. The researchers advocate for nutritional psychiatry and public policies that promote Mediterranean-style eating to protect mental well-being in aging populations.
