TCM Health Preservation – Dietary Therapy

Introduction

As a core component of Traditional Chinese Medicine (TCM) health preservation, TCM diet therapy integrates traditional dietary culture with TCM theories to form a unique approach to health maintenance and disease prevention. Adhering to the core TCM concepts of "preventive treatment of diseases" and "treatment based on syndrome differentiation", it takes the four natures and five flavors of food as the basis to formulate dietary plans in combination with individual constitutions, aiming to regulate the balance of yin and yang and tonify zang-fu organs [1]. Different from modern nutrition that focuses on nutrient composition, TCM diet therapy pays more attention to the overall compatibility of food and its adaptability to the human body. With a long historical heritage, it not only meets the needs of daily diet but also undertakes health care and auxiliary therapeutic functions, becoming an indispensable part of Chinese traditional culture.

Origin and Development of TCM Diet Therapy

The origin of TCM diet therapy can be traced back to primitive society, when ancestors gradually recognized the therapeutic effects of food in the process of foraging. Specialized dietitians had appeared in the Shang and Zhou dynasties, and "Rites of Zhou" recorded officials responsible for the dietary health preservation of the royal family, initially forming the prototype of diet therapy. The Spring and Autumn and Warring States Period laid the theoretical foundation: "Huangdi Neijing" (Yellow Emperor's Internal Classic) put forward the concept of "prioritizing food nourishment", clarified the corresponding relationship between the five flavors of food and zang-fu organs, and constructed a preliminary theoretical framework [1]. The dietary structure principle of "five grains as nourishment, five fruits as supplements, five meats as benefits, and five vegetables as supplements" formed during this period also became an important theoretical origin of TCM diet therapy [3]. In the Han Dynasty, Zhang Zhongjing applied diet therapy to clinical practice in "Shanghan Zabing Lun" (Treatise on Febrile and Miscellaneous Diseases), creating classic prescriptions combining medicine and food such as Danggui Shengjiang Yangrou Decoction [1]. TCM diet therapy achieved great development in the Tang Dynasty: Sun Simiao set up a special chapter on diet therapy in "Qianjin Yaofang" (Essential Prescriptions for Emergencies), emphasizing "treating with food first, then with medicine" [1]. By the Ming and Qing dynasties, the system of TCM diet therapy had matured: Li Shizhen recorded more than 200 kinds of medicinal and edible ingredients in "Bencao Gangmu" (Compendium of Materia Medica), and the theory of "homology of medicine and food" took root in people's hearts [1]. During the Republic of China, Zhang Xichun further developed the idea of diet therapy in "Yixue Zhongzhong Canxilu" (Records of Traditional Chinese and Western Medicine in Combination), putting forward the view that "no medicine is needed, and ordinary food can cure diseases". He was good at using common ingredients such as Chinese yam and kelp for compatibility to treat diseases, enriching the practical application of the homology of medicine and food [4].

Core Theories of TCM Diet Therapy

1. Four Natures and Five Flavors of Food

The four natures (cold, cool, warm, hot) and five flavors (sour, bitter, sweet, pungent, salty) are the core of TCM's understanding of food properties. Cold and cool foods (such as mung beans and bitter gourd) have the effects of clearing heat and detoxifying, and are suitable for people with hot constitution; warm and hot foods (such as ginger and mutton) can dispel cold and tonify yang, and are suitable for people with cold constitution. The five flavors correspond to zang-fu organs: sour enters the liver, bitter enters the heart, sweet enters the spleen, pungent enters the lung, and salty enters the kidney, each with specific therapeutic effects.

2. Syndrome Differentiated Diet and Constitution Adaptation

Individualization is a core feature of TCM diet therapy, which requires formulating dietary plans according to different constitutions (such as qi deficiency, yin deficiency, phlegm-dampness, etc.) and diseases. For example, people with qi deficiency (fatigue, shortness of breath) should eat qi-tonifying ingredients such as astragalus and Chinese yam; people with yin deficiency (dry mouth, night sweats) need to choose yin-nourishing ingredients such as lily and tremella.

3. Homology of Medicine and Food

"Homology of medicine and food" means that many ingredients have both nutritional and medicinal values, serving as a bridge connecting diet and TCM treatment[1]. For example, wolfberry can nourish the liver and kidneys, and chrysanthemum can clear heat and improve eyesight—both are included in the official catalog of items with homology of medicine and food, ensuring their safe application in diet therapy[2]. This theory makes diet therapy an important means of integrating health preservation and disease prevention.

Typical Cases of TCM Diet Therapy

1. Diet Therapy for Common Cold

For wind-cold cold (fever, aversion to cold, clear nasal discharge), ginger-brown sugar water is recommended: boil 3-5 slices of ginger with brown sugar, which can dispel cold and relieve exterior symptoms by utilizing the warm and pungent properties of ginger. For wind-heat cold (sore throat, yellow nasal discharge), mung bean-lotus seed porridge can be eaten, which clears heat and detoxifies with the cold nature of mung beans.

2. Diet Therapy for Spleen-Stomach Weakness

People with spleen-stomach weakness (poor appetite, abdominal distension, loose stools) can eat Chinese yam-lotus seed porridge: Chinese yam and lotus seed tonify the spleen and stomach, and coix seed invigorates the spleen and eliminates dampness. Modern research shows that Chinese yam contains polysaccharides, amino acids and other components, which have pharmacological effects such as regulating the spleen and stomach and immune regulation, making it a preferred ingredient for spleen-tonifying diet therapy[4]. For those with severe qi deficiency, astragalus-chicken soup is suitable, which can tonify qi and invigorate the spleen.

3. Diet Therapy for Yin Deficiency with Internal Heat

Lily-tremella soup is the first choice for people with yin deficiency and internal heat (dry mouth, night sweats): lily nourishes yin and moistens the lungs, clears the heart and calms the nerves, and tremella nourishes yin and moistens dryness, which can effectively relieve symptoms of internal heat. For severe yin deficiency, wolfberry-turtle soup can be eaten to nourish kidney yin.

Modern Value of TCM Diet Therapy

In modern society, TCM diet therapy has attracted much attention due to its natural and non-toxic side effects. It provides a safe health preservation plan for sub-healthy groups (such as relieving fatigue and insomnia through dietary regulation) and assists in the rehabilitation of chronic diseases: hypertensive patients can eat celery and chrysanthemum to assist in lowering blood pressure, and diabetic patients can choose bitter gourd and coarse grains to control blood sugar. Studies have confirmed that the TCM diet therapy model can effectively improve symptoms and reduce mortality in the prevention and treatment of chronic diseases such as metabolic cardiovascular diseases, becoming an important auxiliary means of modern chronic disease management [5]. In addition, health foods with homology of medicine and food (such as wolfberry tea and red date porridge) integrate traditional health preservation with modern life, and their unique concepts have been increasingly recognized internationally, becoming a carrier for the dissemination of Chinese culture.

中医养生——食疗

一、引言

中医食疗作为中医养生的核心组成部分，融合传统饮食文化与中医理论，形成了独特的养生保健与疾病预防方法。它秉持中医“治未病”和“辨证施治”的核心理念，以食物的四性五味为基础，结合个体体质制定饮食方案，旨在调节阴阳平衡、补益脏腑[1]。与侧重营养成分的现代营养学不同，中医食疗更注重食物的整体配伍及其与人体的适应性。凭借悠久的历史传承，它不仅满足日常饮食需求，更承担着保健与辅助治疗功能，成为中国传统文化不可或缺的一部分。

二、中医食疗的起源与发展

中医食疗的起源可追溯至原始社会，祖先在觅食过程中逐渐认识到食物的治疗功效。商周时期已出现专门的食医，《周礼》中记载了负责王室饮食养生的官员，初步形成食疗雏形。春秋战国时期奠定理论基础：《黄帝内经》提出“食养为先”的理念，明确食物五味与脏腑的对应关系，构建了初步的理论框架[1]。这一时期形成的“五谷为养、五果为助、五畜为益、五菜为充”饮食结构原则，也成为中医食疗的重要理论渊源[3]。 汉代，张仲景在《伤寒杂病论》中将食疗应用于临床实践，创制了当归生姜羊肉汤等药食结合的经典方剂[1]。唐代食疗得到极大发展：孙思邈在《千金要方》中设专章论述食疗，强调“先以食治，后以药治”[1]。至明清时期，中医食疗体系趋于成熟：李时珍在《本草纲目》中记载了200余种药食同源食材，“药食同源”理论深入人心[1]。民国时期，张锡纯在《医学衷中参西录》中进一步发展食疗思想，提出“勿须用药，寻常服食之物即可治愈”的观点，善用山药、海带等常见食材配伍治病，丰富了药食同源的实践应用[4]。

三、中医食疗的核心理论

1.食物的四性五味

四性（寒、凉、温、热）与五味（酸、苦、甘、辛、咸）是中医认识食物特性的核心。寒凉食物（如绿豆、苦瓜）具有清热排毒功效，适用于热性体质；温热食物（如生姜、羊肉）能散寒补阳，适用于寒性体质。五味对应脏腑：酸入肝、苦入心、甘入脾、辛入肺、咸入肾，每种味道均具有特定治疗功效。

2.辨证施食与体质适配

个性化是中医食疗的核心特征，要求根据不同体质（如气虚、阴虚、痰湿等）和病症制定饮食方案。例如，气虚体质者（乏力、气短）宜食用黄芪、山药等补气食材；阴虚体质者（口干、盗汗）需选用百合、银耳等滋阴食材。

3.药食同源

“药食同源”指许多食材兼具营养与药用价值，是连接饮食与中医治疗的桥梁[1]。例如，枸杞能滋补肝肾，菊花可清热明目——二者均被纳入官方药食同源目录，保障其在食疗中的安全应用[2]。这一理论使食疗成为融合养生与防病的重要手段。

四、中医食疗典型案例

1.感冒的食疗调理

风寒感冒（发热、恶寒、流清涕）推荐生姜红糖水：将3-5片生姜与红糖同煮，利用生姜的温热辛散特性散寒解表。风热感冒（咽痛、流黄涕）可食用绿豆莲子粥，借助绿豆的寒凉之性清热排毒。

2.脾胃虚弱的食疗调理

脾胃虚弱者（食欲不振、腹胀、便溏）可食用山药莲子粥：山药、莲子健脾养胃，薏苡仁健脾祛湿。现代研究表明，山药含多糖、氨基酸等成分，具有调节脾胃、免疫调节等药理作用，是健脾食疗的优选食材[4]。气虚较重者适宜黄芪鸡汤，能补气健脾。

3.阴虚内热的食疗调理

阴虚内热者（口干、盗汗）首选百合银耳汤：百合滋阴润肺、清心安神，银耳滋阴润燥，可有效缓解内热症状。重症阴虚者可食用枸杞甲鱼汤滋补肝肾之阴。

五、中医食疗的现代价值

现代社会，中医食疗因其天然、无毒副作用的特性备受重视。它为亚健康人群提供安全的养生方案（如通过饮食调理缓解疲劳、失眠），并辅助慢性疾病康复：高血压患者可食用芹菜、菊花辅助降压，糖尿病患者可选用苦瓜、粗粮控制血糖。研究证实，中医食疗模式在代谢性心血管病等慢性疾病的防治中能有效改善症状、降低死亡风险，成为现代慢性病管理的重要辅助手段[5]。此外，药食同源保健食品（如枸杞茶、红枣粥）将传统养生与现代生活融合，其独特理念日益获得国际认可，成为中华文化传播的载体。
