Entering personal information is to register the personal information of the person who uses the device for the first time, and to change the personal information. As shown in Figure 6, first enter the name. The input method can be Chinese characters input, English input and other text input. Chinese character input can be in Pinyin, Wubi and speech recognition. Then enter the gender, not only male and female, but also specific physical conditions, such as: pregnant women 4-6 months, pregnant women 7-9 months, nursing mothers, etc. After that, input data such as age, height, weight, and physical signs, and enter the labor intensity that the user is engaged in. The options are very light manual labor and light physical labor. Medium manual labor, heavy manual labor, extremely light physical labor, etc. Then, it can be judged whether it is a special group, such as whether it has a disease, the name of the disease, or whether it is an athlete, a type of exercise, etc. The type of exercise can be divided into: strength type, endurance type, sensitive skill type and training period, competition period , Recovery period and other options. This special group judgment can be optional, or it can be done without going through this step. Finally, it is determined that the above input is correct, and the above input data corresponding to the user is stored in the memory. And, based on the above data, calculate the dietary reference values of various nutritional components of the user, that is, the amount of various nutritional components that the user should ingest every day, such as calories, protein, fat, carbohydrates, vitamins, and trace elements Such as Ca, Fe, Zη, etc., and store these values in memory.

Specifically, in the above calculation step, the standard weight of the person is first calculated according to the following formula 1 according to the height of the input person:

Formula 1: Standard weight scale or formula for adults;

Such as: rough calculation: standard weight (kg) = height (cm)-105

Calculation: Standard weight (kg) = [height (cm)-100] X 0.9 Note that the above calculations can choose different algorithms based on different positioning of the product and different consumption areas.

The standard weight of infants and children is calculated as follows:

Formula 2. Standard weight scale or calculation formula for infants and children; Age formula

Newborns average 50cm in length

1 to 6 months length (cm) = month age X 2.5 + birth length

Weight (kg) = month age X 0.6 + birth weight

7 ~ 12 months Length (cm) = Month age X 1.2 + Birth length

Weight (kg) = month age X 0.5 + birth weight

2 to 10 years height (cm) = age X 5 + 75

Weight (kg) = age X 2 + 7 or 8

For children, it can be calculated based on actual weight only.

After calculating the standard weight, the reference value of the daily intake of various nutritional components of the user is generated according to the following algorithm.

Taking adult men and women as examples, the above dietary reference values can be generated by referring to the following table:

-Determine daily reference values of various nutrients for users, and provide calculation basis for dietary recommendations;

-When the user queries the recommended food and diet recipes, determine the scope of the recipes.

FIG. 7 is a flowchart of processing the input meal record data by the meal record section. The diet record part is used to record and calculate the content of various nutritional components in the user's diet, that is, the content of various nutritional components in the diet is automatically calculated according to the content of various nutritional components of various foods in the food composition table.

As shown in FIG. 7, first, a user's name is input. The input methods that can be selected are: Chinese pinyin, Wubi font, voice input, etc., or different language input can be selected. Then, enter the user name, enter the recording time, and then enter the name and quantity of the food that the user has consumed (the quantity of food can be calculated in grams). There can be multiple input methods for the food name as described above. After that, confirm whether the above input is correct. If "No", return to the input time step to re-enter the intake time and food; if "Yes", determine whether the food is the same as the personal input by the user. The disease contraindications in the data conflict with each other. If there is a conflict, the user will be warned of “improper food intake”. If there is no conflict, the respective contents of various nutrients in the food in the user's diet will be calculated. Of course, the conflict determination step can also be omitted, and the food component content can be directly calculated, as shown by the dashed line A in FIG. 7. Of course After that, the user inputs whether to complete the selection of the input. If the user continues to input the next food, the user returns to the step of inputting the food name, and enters the next food name and quantity. If the input is completed, it is judged whether there is a conflict of food taboos among various foods that the user consumes at the same time. If the conflict occurs, the user is warned that "inappropriate food" is used. The nutritional components are added up according to the nutritional components to obtain the total value of each of the various nutritional components ingested by the user at this time, and the cumulative number of various nutritional components is displayed item by item on the display. Of course, the conflict determination step can also be omitted, and the accumulated food nutritional components are directly calculated, as shown by the dotted line B in FIG. 7.

The calculation of the respective contents of various nutritional components in the food in the user's diet is calculated according to the following food composition table 3. These food composition tables are stored in the memory in advance and can be accessed during processing.

The calculation formula is: the content of one nutrient ingredient = the amount of the food (unit: 100 grams)

X The content of the nutrient component per 100 grams of the food Table 3. Table of food ingredients (the content of the main nutrients required by the human body in various foods per 100 grams of food);
