The benefits of the Mediterranean diet are no longer limited to protecting the heart and arteries; it seems they extend to providing the mind with a balance that becomes increasingly necessary with aging. This was revealed by a recent scientific study, which found a strong link between following the Mediterranean diet and higher levels of psychological well-being among individuals over the age of 50, showing that the quality of psychological life clearly improves with this dietary pattern, regardless of economic or social conditions or even the individual's general mood.

The study that delved into this link was conducted by a joint research team from University College London and the Barcelona Institute for Global Health (ISGlobal), and its results were published in the journal "BMJ Open." The researchers relied on analyzing data from 3,296 participants aged between 50 and 90 years, who were primarily involved in the "English Longitudinal Study of Ageing." The team monitored the dietary habits of these individuals between 2018 and 2019 through an online platform where they recorded their daily meals, while their psychological status was assessed through periodic questionnaires that continued until 2020.

What is striking about this research is that it went beyond the traditional goals of previous studies that focused solely on monitoring depression or organic diseases; this time it focused on measuring direct positive dimensions in human psychology, such as a person's sense of control over their life, independence, ability to enjoy and achieve self-fulfillment, in addition to having clear goals, energy levels, and an optimistic outlook on the future. The indicators showed that adherence to this diet—based on vegetables, fruits, legumes, fish, and olive oil—significantly and consistently raises these psychological values, even after neutralizing the effects of other factors such as financial status or previous psychological symptoms.

Moreover, the scientific value of the research did not stop at stable times but extended to include periods of crisis; the data showed that the natural decline in mental health experienced by everyone during the COVID-19 pandemic and the accompanying lockdowns was less severe and intense among those who maintained their Mediterranean meals, giving this diet a protective role in absorbing shocks and external pressures.

However, the lead researcher in the study, Camille Lasal, preferred to interpret the results with caution and objectivity, clarifying that the observational nature of the study does not necessarily imply a definitive causal relationship, but she considered that monitoring participants' behavior during the pandemic provided the results with additional strength and credibility. Lasal pointed out that the nutritional components of this diet help the body vitalize in regulating essential processes, such as curbing inflammation, improving gut health, enhancing brain functions, and regulating the body's response to stress.
