The modern definition of physique is “the relatively stable functional and morphological characteristics of the human organism based on genetic variation and acquired characteristics”. The identification of physique can be traced back to the classic Chinese medical text “Huangdi Nei Jing”, in “Ling Shu. In the “Yin and Yang twenty-five people” that is: “first established five forms of gold, wood, water, fire and earth, distinguish its five colors, different from its five forms of people, and twenty-five people with.” And in the “Tongtian seventy-two” will be divided into “Taiyin people, Shaoyin people, the Sun people, Shaoyang people, Yin and Yang people of peace.” And it is pointed out that “all five people have different states, their tendons and bones and blood are different.” It can be seen that the identification of physical constitution in Chinese medicine has a long history. In the “Classification and Determination of Physical Qualities in Chinese Medicine”, Professor Wang Qi, a modern Chinese medicine practitioner, divided people into nine different types of physical qualities, i.e., pinghe, qi deficiency, yang deficiency, yin deficiency, blood stasis, phlegm dampness, damp heat, qi yu, and special endowment, which highly summarized the physical characteristics of different people. In fact, the identification of TCM constitution is also very important for people who are already sick, because it can be used to select medicine according to different constitutions and to guide the dietary allocation for different diseases. From the perspective of Chinese medicine, food itself also has a nature and taste to the meridian, such as “Ling Shu. Five flavors fifty-six” that has: “five grains: Panicum sweet, sour, soybean salty, wheat bitter, yellow millet pungent. Five fruits: jujube sweet, plum sour, chestnut salty, apricot bitter, peach pungent. Five animals: cattle sweet, dog acid, pig salty, sheep bitter, chicken pungent. Five vegetables: sunflower sweet, leek sour, patchouli salty, allium bitter, onion pungent.” “Each of the five tastes goes to its favorite, grain taste sour, first go to the liver; grain taste bitter, first go to the heart; grain taste sweet, first go to the spleen; grain taste pungent, first go to the lungs; grain taste salty, first go to the kidneys.” According to the nature and taste of the food to guide the patient’s dietary contraindications can better assist in treatment, to achieve the effect of medicine and food together with twice the result with half the effort. As we all know, diet and exercise are the basic treatment of diabetes, and diet control is directly related to the success or failure of blood sugar control. In addition to directly assisting in lowering sugar, good dietary control can also ensure the nutritional needs of the body and enable patients to reach the weight limit as much as possible, thus reducing the burden on the pancreatic islets and effectively preventing the occurrence of complications. According to the method of classifying the 9 types of constitution, the calm constitution is mostly seen in healthy people, while the special endowment mainly refers to a group of people with allergies. The other 7 types of constitution basically cover the physical characteristics of the diabetic population. For different patients at different stages of disease and therapeutic interventions, their TCM symptoms are variable or changeable, while constitution is a relatively stable characteristic that is basically unchanged over a long period of time. Therefore, the combination of TCM constitution identification to guide the daily diet of diabetic patients is easier to master, so that passive diabetic diet control becomes active dietary treatment, thus truly bringing into play the advantages of TCM food therapy and enabling the majority of diabetic patients to truly gain greater benefits from their diet.
