Shi Liao or Chinese food therapy is a method of healing using natural foods rather than medications.
Chinese nutritional therapy is a form of treatment of traditional Chinese medicine. It is especially popular among the Cantonese Chinese who love to prepare slow-cooked soups. One very popular soup served by these people is rice soup which is known to others as jook and congee. Among Asians, rice soup is a traditional breakfast and its recipe can be varied, depending on flavor and their desired benefits.
Chinese nutritional therapy has been used as far back as 2000 BCE. Earliest documents pertaining to this therapy however, have been dated only about 500 BCE. Around 300 BCE, the Nei Jing or the Yellow Emperor’s Classic of Internal Medicine was written. This text was a major factor in the development of Chinese nutritional therapy. It categorized foods based on their attributes, natures, five tastes, and four food groups.
Theories Regarding Food
The concepts of yin and yang are applicable when it comes to cooking and food. Yin foods are known to reduce the heat of the body (i.e., decrease the metabolism) while yang foods are known to increase the heat of the body’s (i.e., increase the metabolism). By nature, Yin foods are likely to have high water content while Yang foods are likely to be packed with food energy, particularly fat energy. Ideally, to maintain balance in the body, one needs to eat both types of food. If you eat too much Yang food, you might suffer from bad breath and acne; conversely, if you eat insufficient amounts of Yang food, you experience anemia or lethargy.
As a distinct classification, there are foods that are known to be extremely healing/restorative to the body.
Cantonese Categorization of Food
The reaction of the body to food is very important to the Cantonese people. Foods are categorized appropriately, and nutrition is modified based on the condition(s) of the body. In reality, a majority of Cantonese people religiously adhere to nutritional therapy in their daily lives. Listed below are the food categorizations used frequently:
|Categorization||associated effects/symptoms||examples||health benefits|
|greasy||Leads to acne outbreaks, runny stool, gastric problems etc.||Bacon and all greasy foods||Avoidance at outbreak|
|wet heat (yang)||leads to burning either because of alkalinity or acidity, causes burning urination, mouth sores, etc.||Pineapple, mango, cherry||sugar cane, chrysanthemum, Prunella vulgaris L., Imperata arundinacea|
|yin||resulting in green or whitish face (blood has low oxygen levels), weakness, dizziness, etc.||Green tea, vegetables, fruits (melon types) such as honeydew, cantaloupe, watermelon||Foods with dry fire or boosting qualities|
|Blocking||Results in abdominal gas, indigestion, etc.||Foods rich in fiber such as chestnuts and yams||Malt, haw fruit, malt|
|poisoning||Results in hemorrhoids, acne outbreaks, swelling or pus in wound, etc.||Shellfish, bamboo shoot, goose, duck||Avoidance at outbreak|
|dry fire (yang)||Results in nosebleed, chapped lips, dry skin, etc.||Lychee, chili pepper, dried meat, deep fried food.||Cooling or yin foods|
|Cooling||Mild form of yin which offset the dry fire form. When overused, it’s also considered as yin.||Sugar cane, American ginseng, beer, Imperata arundinacea||Not required, if not overused|
|Nourishing||Soothing, moisturizing||Lily bulb, yam, apple, lotus seed, longan, fig, pear, etc.||Not required|
|Boosting||Replenishes Chi and blood. When overused also considered as dry fire||Red dates, mutton, beef wild games, snake||not required, if not overused|
|Energizing||Enhanced circulation of Chi and blood||Korean ginseng, wine||not required|
|Strengthening, engendering||Boosts certain internal functions||varied||not required|
A person’s specific yin & yang determines the level of susceptibility a person has to the effects of these foods. Only after excessive consumption of certain kinds of food, a person who is generally healthy due to a neutral constitution will likely experience intense reactions to the effects of these foods. A person with a yang constitution usually can consume practically all forms of yin food with no adverse effects, but may get a nose bleed easily if he eats a few amounts of yang food for a long time. A person with a yin constitution is typically extremely unhealthy and easily reacts to either yang or yin food. To restore the health of a yin person, nourishing or bolstering kinds of food is recommended.
