DHA对缓解当代大学生焦虑的作用机制及膳食营养干预

The Mechanism of DHA in Alleviating Anxiety among Contemporary College Students and Dietary Nutritional Intervention

摘要: 当代大学生面临学业、社交、就业等多重压力，焦虑情绪发生率逐年攀升，已成为影响其身心健康的重要问题。DHA (二十二碳六烯酸)作为Omega-3多不饱和脂肪酸的核心成员，不仅是大脑的必需营养成分，还在情绪调节、神经炎症抑制及应激反应调控中发挥关键作用。本文通过对大学生焦虑的现状、影响因素进行分析，系统探讨DHA通过调节神经递质平衡、抑制神经炎症、稳定下丘脑–垂体–肾上腺(HPA)轴功能等途径缓解焦虑的作用机制，深入挖掘DHA缓解大学生焦虑的核心作用机制，提出针对大学生群体的DHA缓解大学生焦虑的膳食干预方案，为大学生焦虑的营养防治提供理论依据与实践参考。

Abstract: Contemporary college students are confronted with multiple pressures such as academic studies, social interactions, and employment. The incidence of anxiety is increasing year by year, which has become an important issue affecting their physical and mental health. DHA (docosahexaenoic acid), as a core member of Omega-3 polyunsaturated fatty acids, is not only an essential nutrient for the brain but also plays a key role in mood regulation, inhibition of neuroinflammation and regulation of stress responses. This article analyzes the current situation and influencing factors of anxiety among college students, systematically explores the mechanism by which DHA alleviates anxiety through regulating neurotransmitter balance, inhibiting neuroinflammation, and stabilizing the function of the hypothalamic-pituitary-adrenal (HPA) axis, and deeply explores the core mechanism of DHA in alleviating anxiety among college students. Propose a dietary intervention plan for DHA to alleviate anxiety among college students, providing theoretical basis and practical reference for the nutritional prevention and treatment of anxiety among college students.
