This study aims to identify the relationships between eating habits and psychological adjustment and health perception, and to analyze potential mediating role of healthy and unhealthy foods in the relationship between adherence to the Mediterranean diet (MedDiet) and the psychological constructs and health perception. The sample was selected through stratified random cluster sampling and was composed of 788 university students. The participants responded to a MedDiet adherence screener and food consumption inventory to assess the eating habits, instruments measuring self-esteem, life satisfaction, curiosity and sense of coherence to assess the psychological adjustment, and single item measuring perceived health. The results revealed 41.9% of the participants had a high consumption of vegetables and 85.1% a low consumption of energy drinks, while 29.9% showed a high adherence to the MedDiet which was positively associated to each psychological variable and healthy foods and negatively with unhealthy foods. In conclusion, a higher adherence to the MedDiet, and the consumption of fruits and vegetables is related to higher psychological adjustment and health perception. However, the relationships between MedDiet and the psychological variables and health perception were fully or partially explained because of the consumption of healthy and unhealthy foods.
本研究旨在确定饮食习惯与心理调整和健康感知之间的关系，并分析健康和不健康食品在坚持地中海饮食（MedDiet）与心理结构和健康感知之间关系中的潜在中介作用。该样本通过分层随机聚类抽样选择，由 788 名大学生组成。参与者回答了 MedDiet 依从性筛查器和食物消费清单，以评估饮食习惯，使用自尊、生活满意度、好奇心和凝聚力感评估心理调整，以及使用单项衡量健康感知。结果显示，41.9%的参与者蔬菜摄入量较高，85.1%的参与者能量饮料摄入量较低，而 29.9%的参与者坚持地中海饮食，这与每个心理变量和健康食品呈正相关，与不健康食品呈负相关。总之，更高的地中海饮食依从性和水果、蔬菜的摄入与更高的心理调整和健康感知有关。然而，由于健康和不健康食品的摄入，地中海饮食与心理变量和健康感知之间的关系被完全或部分解释。
