What Chinese dietary therapy is
Chinese dietary therapy (also called Chinese food therapy or food energetics) is the part of traditional Chinese medicine that uses everyday foods and food-like herbs to support health. It is defined by sorting foods into "cooling" (yin) and "heaty" (yang) groups and adjusting the amount of each in the diet. [1] Food in this tradition is not just fuel. It is described as having a nature, a flavor and a direction of action.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 the traditional description:- "Hot" foods such as pepper, chili and garlic are said to warm the body and increase yang. [2]
- "Cold" foods such as tomatoes and bananas are said to cool the body and cool internal heat. [2]
- Warm and cool foods are described as milder versions of these. [2]
These labels do not refer to the actual temperature of the food or to calories. They belong to the same framework as yin-yang and the five phases, which are explained as traditional concepts on Qi, Yin and Yang, Five Phases and Meridians. They are not biomedical findings.
Medicine and food together
In China, a legal 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 that the list has been revised over time. [3] Ideas about everyday foods therefore sit next to herbal medicine, and the boundary is set by regulation as well as tradition. For herbal products themselves, see Chinese Herbal Medicine.What the research shows
Evidence labels used here: traditional use only, insufficient evidence, established.| Question | What the source found | Label |
|---|---|---|
| Does sorting foods into hot and cold improve health outcomes? | A review in a gastroenterology journal found no standard way of assigning the hot or cooling classification and limited mechanistic reasoning or clinical studies supporting its benefit in functional dyspepsia and irritable bowel syndrome. [1] | Insufficient evidence |
| Is there a proven diet for irritable bowel syndrome? | The same review notes that a low-FODMAP diet is an efficacious therapy for people with IBS, and suggests Chinese food therapy could be explored alongside it. [1] | Low-FODMAP: established for IBS. Chinese food therapy: insufficient evidence |
Proper evidence not found for other uses we checked. We searched PubMed for reviews of Chinese dietary therapy and food energetics and found no systematic reviews of trials we could read that show benefit for a named condition. Absence of reviews does not prove the approach is ineffective. It means the question has not been tested well.
Practical, low-risk ways people use the ideas
Many people draw cultural and family meaning from these food traditions, and eating a varied diet with plenty of vegetables, fruit and whole foods is compatible with mainstream advice. If you enjoy warm soups in cold weather or fresh fruit in hot weather, that is a food preference, not a treatment.Where care is needed:
- Do not restrict whole food groups because of a "cold" or "hot" label without discussing it with a clinician or dietitian, especially with diabetes, kidney disease, pregnancy, a history of an eating disorder, or in children.
- Food labeled as "medicine" is not automatically safe. Herbal soups and tonics can contain potent herbs that interact with medicines. See Chinese Herbal Products: Quality, Contamination and Medicine Interactions.
- This page does not give any personal food plan, because plans based on a practitioner's pattern assessment are individual and the assessment itself has limited reliability (see TCM Consultation).
Who should get conventional care first
Persistent digestive symptoms, unexplained weight loss, blood in stool, severe or ongoing pain, and managing diabetes or kidney disease need medical assessment. Dietary tradition can sit beside that care but not replace it. [4]Related pages

Are hot and cold foods about temperature?
No. In this tradition the labels describe an assumed effect on the body, so a food such as garlic is called "hot" because of its traditional nature, not because of 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 with 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.
Is Chinese dietary therapy the same as taking herbs?
Not exactly, but the two overlap. The tradition treats foods and herbs with the same classification, and some substances are legally both. [2][3]
Where do I find reliable information about specific foods?
