The food and beverage we consume daily - whether it is of hot or cold properties - should be chosen according to a person's constitution and condition. Inappropriate intake will lead to extreme energy excess inside the body and disturb the yin yang balance. A well-planned diet promotes the body to function optimally, and ensures a full recovery from diseases. The Chinese have a long history in dietary practice and have accumulated much experience in taboos

Dietary restraint in certain health conditions
A basic principle in TCM is that when a person suffers from a certain disorder or takes medication, he should avoid certain foods. For example, a person suffering from generalized body swelling should refrain from salty food, and a person suffering from diarrhea should avoid a greasy diet. TCM physicians usually advise their patients to consider the following aspects:

During a recovery stage or just after an illness, individuals usually have a poor appetite. They should eat in small meals and cut down the amount of grain and wheat products, such as noodles or cakes that made from glutinous rice, barley and wheat.

Diarrhea patients should avoid cold foods and drinks, and also limit the amount of fruits and raw vegetables.

For those who have excess phlegm and dampness (often in those with Hypertension, Diabetes, Obesity, Asthma, Gout, Coronary Heart Disease, and cardiovascular problems), they should cut down the amount of oily, fatty, deep fired foods, and even animal organs and daily products.

For those who have a wind-heat disharmony, phlegm-heat disharmony or skin problems, fishy and other strong flavor meat should be avoided, such as sea fishes, shrimp, crab, mussel, mutton and venison.

Individuals with internal heat, that shows dry cough, dry mouth, hot flush, or dry stool should avoid hot and pungent foods such as onion, ginger, garlic, chilli pepper, pepper, garlic chives, wine and cigarette.

"Trigger foods" are referring to certain items that can cause a relapse of preexisting health problem to an individual. For example, buckwheat, bean sprouts, goose, chicken head, duck head, and pig head are generally not recommended to those who have Asthma, convulsion, Stroke and skin problems, while bean sprouts and coriander should be avoided in the early stage of measles.

It should be noted that TCM food taboos are for general reference only; they might have different results in different people, and the undesired effects may be altered during cooking too. Since there have been no recent studies on possible negative interaction, it is difficult to determine the outcome and hence, infrequent consumption is advised.
