Although an increasing number of people are now committed to pursuing a healthy diet, it remains unclear how mental health changes during this process. The present study aimed to examine the combined effect of healthy dietary intention and behavior on depression and anxiety across two sub-studies. This study consisted of two parts: a cross-sectional survey (Study 1) involving 1,433 college students and an 11-day daily diary study (Study 2) with 117 college students. Polynomial regression and response surface analysis indicated that in cases of congruence, individuals' intention and behavior align at a high level and were associated with lower levels of depression and anxiety in the motivational phase but were not found similar association in the volitional phase. In cases of incongruence, individuals with high intention-low behavior tend to experience lower levels of depression and anxiety in the motivational phase. However, individuals with high intention-low behavior tend to experience higher levels of depression and anxiety in the volitional phase. These findings not only enrich the current understanding of diet and health but also contribute to the development of holistic strategies for promoting a healthy diet.
尽管现在越来越多的人致力于追求健康饮食，但在此过程中心理健康如何变化仍不清楚。本研究旨在通过两项子研究考察健康饮食意图和行为对抑郁和焦虑的综合影响。本研究包括两个部分：一项涉及1433名大学生的横断面调查（研究1）和一项针对117名大学生的为期11天的日记研究（研究2）。多项式回归和反应面分析表明，在一致的情况下，个体的意图和行为在高水平上保持一致，并且在动机阶段与较低水平的抑郁和焦虑相关，但在意志阶段未发现类似关联。在不一致的情况下，高意图低行为的个体在动机阶段往往经历较低水平的抑郁和焦虑。然而，高意图低行为的个体在意志阶段往往经历较高水平的抑郁和焦虑。这些发现不仅丰富了当前对饮食与健康的理解，也有助于制定促进健康饮食的整体策略。
