[Impact of the Mediterranean diet and the consumption of fermented beverages on subjective well-being in different contexts in Spain].

Introduction: The relationship between the Mediterranean diet, the consumption of fermented beverages (beer and wine), and subjective well-being in Spain was investigated. Using a cross-sectional study with 2,752 participants, dietary patterns and emotional well-being were evaluated in contexts such as work, the gym, and bars/restaurants. The results showed that context significantly impacts dietary habits and well-being. Participants at the gym adhered more to the Mediterranean diet and reported fewer negative emotions compared to other contexts. Correlation maps indicated that beer consumption was associated with a higher intake of red meat, while wine was related to a higher consumption of fish and seafood. Additionally, the study found that participants following the Mediterranean diet experienced higher levels of emotional well-being, with less frequent negative emotions such as anxiety and anger, and higher levels of life satisfaction, especially in contexts like the gym. These findings suggest that public health interventions should consider contextual factors to promote healthy eating habits and improve emotional well-being, highlighting the importance of the Mediterranean diet in health and the prevention of psychological problems.
