Overview

Dietary therapy and health preservation is a unique practice that combines traditional Chinese medicine with dietary culture. It refers to the rational adjustment of daily diet, utilizing the properties of food to prevent diseases, regulate the body, and promote health and longevity. It is rooted in the ancient philosophy of "medicine and food sharing the same origin," which holds that food, like medicine, possesses the attributes of the Four Natures (cold, hot, warm, cool) and the Five Flavors (sour, bitter, sweet, pungent, salty), and can influence the body's yin-yang balance and the functions of the internal organs. Dietary therapy and health preservation is not simply nutrition; it is a comprehensive life wisdom that integrates diet, health, natural laws, and life philosophy, emphasizing personalized regulation tailored to the individual, the season, and the local environment.

History

The history of dietary therapy and health preservation is long and almost synchronous with the development of Chinese civilization. As early as the Zhou Dynasty, the imperial court had established the position of "Food Doctor" (食医), whose duty was to "manage the harmony of the king's six foods, six drinks, six delicacies, hundred dishes, hundred sauces, and eight treasures," specifically responsible for regulating the monarch's health through diet. This is considered the world's earliest nutritionist. The Yellow Emperor's Inner Canon (《黄帝内经》) from the Spring and Autumn and Warring States period laid the theoretical foundation, explicitly proposing the dietary structure principle of "the five grains for nourishment, the five fruits for assistance, the five livestock for benefit, the five vegetables for supplementation; consume them in harmony of their qi and flavor to replenish essence and boost qi," and emphasizing the preventive concept of "treating disease before it arises."

Zhang Zhongjing, the "Sage of Medicine" of the Han Dynasty, extensively used foods such as ginger, jujube, and japonica rice as medicine in his work Treatise on Cold Damage and Miscellaneous Diseases (《伤寒杂病论》), pioneering the combination of drugs and food in treatment. Sun Simiao of the Tang Dynasty dedicated a chapter titled "Food Therapy" (食治) in his Prescriptions Worth a Thousand Gold (《千金要方》), systematically discussing the therapeutic effects of food. He pointed out, "A physician must first thoroughly understand the source of the disease, know what has been violated, and treat it with food. If food therapy does not cure it, then prescribe medicine," placing dietary therapy above drug treatment. Subsequently, physicians throughout the ages, such as Meng Shen (author of Materia Dietetica 《食疗本草》) and Hu Sihui (author of Principles of Correct Diet 《饮膳正要》), continuously enriched and developed the theory and practice of dietary therapy, making it a mature discipline.

Main Characteristics

The core of dietary therapy and health preservation lies in balance and harmony. Its main characteristics can be summarized as follows:

1. Medicine and Food Sharing the Same Origin: Many substances are both food and medicine, such as Chinese yam, red dates, goji berries, Job's tears, and ginger. They have mild properties, satisfying both appetite and providing regulatory effects.
2. Pattern Differentiation for Dietary Therapy: This is the embodiment of the TCM concept of "pattern differentiation and treatment" in diet. Based on an individual's constitution (e.g., yin deficiency, yang deficiency, qi deficiency, phlegm-dampness, etc.), seasonal changes, geographical environment, and specific symptoms, foods with corresponding natures and flavors are selected for regulation. For example, those with a cold constitution should consume warm-natured foods (like mutton, ginger), while summer calls for heat-clearing foods (like mung beans, watermelon).
3. Holistic Concept: Dietary therapy focuses not only on local symptoms but also on the overall balance of the body's organs, qi and blood, yin and yang, as well as the harmony between humans and the natural environment (seasonal climate, region).
4. Emphasis on Nature, Flavor, and Channel Tropism: Each food has its specific "Nature" (cold, hot, warm, cool), "Flavor" (sour, bitter, sweet, pungent, salty), and "Channel Tropism" (which meridian or organ it acts upon). Through combination, the goal of harmonizing qi and blood and balancing yin and yang is achieved.
5. Focus on Prevention: It emphasizes strengthening the constitution and enhancing "righteous qi" (immunity) through daily diet to "treat disease before it arises," preventing the occurrence and development of illness.

Cultural Significance

Dietary therapy and health preservation transcends the purely medical realm and is deeply rooted in traditional Chinese culture. It embodies the philosophical concept of "harmony between human and nature," closely linking human health with natural rhythms. Simultaneously, it reflects the pragmatic and moderate attitude of the Chinese people—pursuing health while enjoying delicious food and practicing the way of health preservation in the details of daily life. Knowledge of dietary therapy is passed down through families, becoming an important bond for maintaining kinship and cultural heritage. A pot of carefully prepared soup often carries care and warmth. In contemporary society, facing fast-paced life and health challenges, the concepts advocated by dietary therapy and health preservation—conforming to nature, balanced moderation, and prevention first—provide valuable Eastern wisdom for global healthy living and have also become an important component of China's cultural "soft power."
