What Chinese dietary therapy is
Chinese dietary therapy (also called Chinese food therapy or food energetics) is the part of traditional Chinese medicine (TCM) that treats everyday foods, and some food-like herbs, as having properties that matter for health. One review defines it as sorting foods into "cooling" (yin) and "heaty" (yang) groups and adjusting how much of each a person eats. [1] Food in this tradition is more than fuel. It is described as having a nature, a flavor and a direction of action.This page is the overview. Each topic below has its own page. It is information only, not a diet plan.
How the tradition describes foods
One overview of the framework says herbs and foods are classified by thermal nature, flavor, organ network and the direction of their effect. [2] In that description, "hot" foods such as pepper, chili and garlic are said to warm the body, and "cold" foods such as tomatoes and bananas are said to cool internal heat. [2] The labels do not mean the food's temperature or its calories. They belong to the same traditional framework as yin-yang and the five phases (see Qi, Yin and Yang, Five Phases and Meridians as Traditional Concepts). They are traditional explanations, not biomedical findings.The dietary topics in this library

- Dampness, Spleen and "Digestive Fire" contrasts traditional digestive advice with nutrition research.
- Postpartum Confinement (Zuo Yue Zi) covers the month after birth, with the research and safety points.
- Medicinal Foods in China explains where food ends and medicine begins.
Food and medicine overlap
In China an official list names substances that count as both food and medicine. A 2025 review of that list describes "substances with both edible and medicinal values" as a standardized name governed by existing regulations, and notes the list has changed over time. [3] For herbal products themselves, see Chinese Herbal Medicine.What the research shows
Who should get conventional care first
Persistent digestive symptoms, unexplained weight loss, blood in stool, severe pain, or managing diabetes or kidney disease need medical assessment. NCCIH advises not to use TCM to replace or delay conventional care. [6] Never stop or change a medicine or prescribed diet on your own.Related pages
For evidence-based food profiles see Explore Functional Foods. The wider tradition is on What Is Traditional Chinese Medicine?.Frequently asked questions
Are hot and cold foods about temperature?
No. The labels describe an assumed effect on the body in the traditional framework, so a food such as garlic is called "hot" by its nature, not by how it is served. [2]
Is there proof that eating by food energetics works?
A review found no standard way to classify foods as heaty or cooling and little clinical research supporting benefit for gut conditions. [1]
Can I use Chinese dietary therapy alongside a medical diet?
Tell your doctor or dietitian what you plan to change. Do not stop or change medicines or a prescribed diet on your own. [6]
Is Chinese dietary therapy the same as taking herbs?
Not exactly, but they overlap. The tradition classes foods and herbs in the same way, and some substances are legally both food and medicine in China. [2][3]
Where can I find reliable information about specific foods?
Use the food profiles on this site, which state what research shows for each food, such as Explore Functional Foods.

How to read the evidence labels
Labels used on this page: traditional use only, preclinical, insufficient evidence, established.
| Question | What the source found | Label |
|---|---|---|
| Does sorting foods into hot and cold improve health outcomes? | A gastroenterology review found no standard way to assign the hot or cooling classification, and limited mechanistic rationale or clinical studies supporting benefit in functional dyspepsia and irritable bowel syndrome. [1] | Insufficient evidence |
| Can "hot" and "cold" be linked to measurable food properties? | A review of 20 years of literature said the cold-hot nature has been linked to food chemistry and to biological effects, but studies tying nature to specific foods are insufficient. [4] | Preclinical |
| Is there a proven diet for irritable bowel syndrome? | The same gastroenterology review notes a low-FODMAP diet is an efficacious therapy for IBS. [1] See Low-FODMAP Diet. | Low-FODMAP: established. Chinese food therapy: insufficient evidence |
Proper evidence not found for benefit in other named conditions. We searched PubMed for reviews and trials of Chinese dietary therapy and food energetics and found no systematic review of trials showing benefit for a named condition. That means the question is largely untested, not that it has been shown not to work.
Safety and common sense
- A varied diet with plenty of vegetables and fruit fits mainstream advice. The NHS Eatwell Guide, for example, says to eat at least 5 portions of fruit and vegetables a day and to base meals on starchy foods, choosing higher fiber varieties. [5]
- Do not cut out whole food groups because of a "hot" or "cold" label without talking to a clinician or dietitian, especially with diabetes, kidney disease, pregnancy, a history of an eating disorder, or in children. See Eating Patterns Compared.
- A food called "medicine" is not automatically safe. Herbal soups and tonics can contain potent herbs. Reports on TCM herbal products have found contamination with undeclared drugs, heavy metals and incorrect herbs. [6] Ask a clinician or pharmacist before combining them with medicines, and see Chinese Herbal Products: Quality, Contamination and Medicine Interactions.
- This site gives no personal food plan. Plans based on a practitioner's pattern assessment are individual, and the assessment itself has limited reliability (see TCM Consultation).
