Introduction to Traditional Chinese Nutrition Featuring Fruits, Vegetables, Nuts


There are are a number of vegetables, fruits, and nuts which are used in Traditional Chinese Medicine (TCM) as a part of nutritional healing. Foods have been shown to be capable of helping the body to heal itself. A food that has special beneficial properties is generally very safe, because they have been used widely by many people. Some exceptions you may consider would be for persons with life threatening allergies to foods such as peanuts, or that honey is contraindicated for babies. In China you can go to a specialty restaurant in which you will be served a meal appropriate to your health pattern. The herbalist will check your tongue and pulse as a part of the standard intake, and then you receive an appropriate meal served for your condition. What is served for one person will be different for the next.

The best choice for foods to be used to promote wellness are those grown by organic methods with out chemical pesticides. The worst choice is fruits and vegetables grown outside of the US, such as Chile and Mexico, where regulations of chemical pesticides is less strict than the US. Another poor choice especially for raw fruits and vegetables are those that are genetically modified (GM). This topic is discussed in Jane Goodall's book Harvest for Hope. Wild and domestic animals both avoid feed from genetically engineered foods in favor of natural foods. While conducting experiments in the United Kingdom, Dr. Arpad Pusztai found that GM foods were less nutrient dense compared to non GM foods. Further he found that animals who were fed raw GM foods suffered immune deficiencies and internal tissue damage, specifically the thymus, spleen, brain, liver, testicles, intestines and pancreases, while animals fed the same GM foods in the cooked form remained healthy. Pusztai concluded based on his results that the process of genetic engineering itself was responsible for the organ damage and immune dysfunction. GM foods are unlabeled as such in the US, which is another reason to choose organic food.

Traditional Chinese herbs and foods are characterized by their flavor, temperature, the systems of the body that they act on, and their specific action on the body. Naturally sweet foods such as sweet potato, pumpkins and squash are said to act on the Stomach and Spleen to benefit the digestive system. Pungent foods such as onion and ginger can open the Lungs to help clear a head cold. Sour foods such as lemon and cider vinegar are often used to relieve irritability caused by stagnation and congestion in the Liver. The first way in which herbs and foods are described is by nature which includes: hot, warm, neutral, cool or cold. Second, they are described by flavor which includes: sweet, pungent, bitter, sour, salty, or neutral. Some foods are very easy to identify by taste, for example anyone could tell you that a lemon is sour. In this way the action of foods with a particular flavor was determined through observations by Chinese herbalists over time. The flavor of more subtle tasting foods has been determined by deductive reasoning based on their functions. Generally speaking the herbs and foods are said to act on one or more of the TCM organ systems partially in relation to their flavor. The TCM paradigm has it's own vocabulary which does not precisely correspond with biomedical terminology. Organs listed refer to the TCM organ system:

* Bitter foods act on the Heart and Small Intestine.
* Pungent foods act on the Lungs and Large Intestine.
* Salty foods act on the Kidneys and Urinary Bladder.
* Sweet foods act on the Stomach and Spleen (corresponds well with the biomedical pancreas).
* Sour foods act on the Liver and Gall Bladder

The following are a few of the more common fruits, vegetables and nuts used therapeutically in traditional Chinese nutrition with a brief description of their nature, flavors, actions and indications. These are foods that can either be grown or easily purchased in the Daytona area. Starred* foods indicate those which we plan to grow in the Fair Share Garden either this Spring or as Winter crops.
