The nutrition intake reference amount calculation unit 12 calculates the user's reference amount of nutrition intake based on the user's body information acquired from the communication unit 11 and information included in the competition information.

  Here, the reference amount of nutrient intake is an amount that serves as a guide for intake of the nutrition that the user ingests, and includes at least the reference intake amounts of energy and nutrients. The energy intake reference amount (hereinafter also referred to as energy intake reference amount) is a reference amount of energy intake that is the source of physical activity, and is the total amount of energy intake obtained comprehensively from various nutrients. It is the amount which becomes a standard of. Alternatively, the energy intake reference amount is an amount that serves as a guide for the intake of each of the nutrients of protein, lipid, and carbohydrate that can directly derive the energy intake from the intake of the nutrient among various nutrients. The nutrient intake standard amount (hereinafter also referred to as the nutrient intake standard amount) is an amount that is a standard for the intake of each nutrient, including the above-mentioned proteins, lipids, carbohydrates, minerals (for example, iron), vitamins, etc. is there.

  The user terminal 20 is a terminal used by the user. As the user terminal 20, a smartphone, a tablet terminal, or a PC (Personal Computer) is used. Here, a smartphone is assumed as the user terminal 20. A dedicated application program (hereinafter referred to as a dedicated application) corresponding to the nutrition management system 1 is installed in the user terminal 20. The dedicated application is software that can acquire, for example, a reference amount of nutrition required for the user based on information input from the smartphone by the user.

  The nutrient intake standard amount database 30 stores various data necessary for calculating the user's reference amount of nutrient intake.

FIG. 2 is an example of data stored in the nutrient intake reference amount database 30 according to the first embodiment of the present invention.
As shown in FIG. 2, the nutritional intake standard amount database 30 stores physical information, competition information, and nutritional intake standard information for each user ID.
The body information is information about the user's body. The competition information is information regarding the competition performed by the user. The nutrient intake guide information includes information on the energy intake guide amount required by the user and the nutrient intake guide amount.

The estimated nutrient intake database 30 includes items of height, weight, sex, and age as physical information. The competition information includes items of competition classification, period division, and amount of exercise. Moreover, there are items of “energy” and “nutrients” as nutrient intake guide information. Here, “energy” means an estimated intake amount of energy, and “nutrient” means an approximate intake amount of nutrients.
The item “energy” includes total energy intake, and the item “nutrient” includes items of nutrients such as protein, lipid, carbohydrate, etc.

  In addition, in the example of FIG. 2, although the example in the case of having the item of total intake energy as an item of "energy" is shown, it is not limited to this. Among the nutrients memorized in the item of “Estimated intake of nutrients” as an item of “Energy”, a protein that is a nutrient that is a source of energy and can directly derive energy intake from the intake amount, The item of each nutrient of lipid and carbohydrate may be shown, and the intake standard amount of each nutrient may be stored.

  The competition classification is divided into, for example, endurance system, instantaneous system, ball game system, technology system, aesthetic system, and the like. Sports that belong to the endurance system include marathons, swimming, long distance running, and bicycles. Examples of the sports belonging to the flashing system include wrestling, weight lifting, and short distance running. As sports belonging to the ball game system, there are soccer, volleyball, tennis and the like. Examples of the sports belonging to the technical system include golf, shooting, and archery. Examples of competitions that belong to aesthetics include gymnastics, figure skating, and dance.

  In addition, the example of the competition classified by said competition classification is an illustration to the last, and is not limited to this. The competition classification may be anything that can be used as information for calculating the required amount of nutrient intake according to the competition. For example, it may be consumed during the competition depending on the position in charge of the competition. You may make it change a competition classification according to the quantity of energy assumed. In this case, for example, if the user who is in charge of the goalkeeper does not necessarily categorize the competition classification of the user who plays soccer as a competition, it is not necessarily classified as a ball game system as described above. For example, it is possible to make a competition classification that seems more appropriate from the viewpoint of energy consumption.

  For example, information on a match period, a training period, or an off period is stored in the period information. Moreover, information such as the day before, the day of the game, immediately before, immediately after, etc. can be stored in the period information. Further, the period information may include information such as an injury period indicating a period of injuries and a rehabilitation period indicating a period of recovery from the injuries. In the exercise amount, for example, information on how many days a week is exercised is stored as a daily activity amount. Also, as the amount of exercise, information indicating the time spent exercising during the day and the total time spent exercising during the week is stored together with or instead of information indicating how many days of exercise per week. You may make it do.

  FIG. 3 is a block diagram showing a schematic configuration of the user terminal 20 according to the first embodiment of the present invention. The user terminal 20 includes a control unit 21, a storage unit 22, a communication unit 23, an input unit 24, and a display unit 25.

The storage unit 22 stores various programs and data. The program stored in the storage unit 22 includes a dedicated application 26 that communicates with the management server 10 and acquires a reference amount of nutrient intake. The communication unit 23 performs data communication with the management server 10 via the network 40.

  The input unit 24 receives input from a user who operates the user terminal 20. When a smartphone is used as the user terminal 20, a touch panel arranged on the display unit 25 is assumed as the input unit 24. In this case, a user ID, body information, competition information, and the like are input to the input unit 24 by a user's touch panel operation.

  The display unit 25 displays various information. When a smartphone is used as the user terminal 20, a liquid crystal panel or organic EL (Electro-Luminescence) is assumed as the display unit 25.

  Next, an outline of the operation of the nutrition management system 1 according to the first embodiment of the present invention will be described.

  When the user intends to acquire the reference amount of nutrition intake, the user activates the dedicated application 26 of the user terminal 20 and connects the user terminal 20 to the management server 10. When the user terminal 20 is connected to the management server 10, a user information input screen is displayed.

  FIG. 4 is an example of a user information input screen of the user terminal 20. As shown in FIG. 4, the user information input screen includes a physical information input screen 101 (FIG. 4A) and a competition information input screen 102 (FIG. 4B). As shown in FIG. 4A, the physical information input screen 101 is provided with a user ID input field 110 and input fields 111a to 111d for the user's height, weight, sex, date of birth, and the like. . On the physical information input screen 101, the user inputs a user ID in the input field 110, and inputs physical information such as the user's height, weight, sex, date of birth, etc. in the input fields 111a to 111d.

  As shown in FIG. 4B, the competition information input screen 102 is provided with input fields 112 a to 112 c for competition items, period divisions, exercise amounts, and the like, and a button 113. The user inputs competition information such as the competition item, the period, and the amount of exercise in the input fields 112a to 112c.

  When physical information and competition information are input to the user terminal 20 by user operation, the physical information and competition information of the user are sent to the management server 10 via the network 40. When the management server 10 receives the user's physical information and competition information from the user terminal 20, the management server 10 stores the information in the estimated nutrient intake database 30.

In addition, when the management server 10 stores the user's physical information and competition information in the nutrition intake reference amount database 30, the management server 10 processes the user's physical information and competition information to obtain the nutrient intake reference amount database 30. You may make it save to. For example, as shown in FIG. 4 (A), the information input in the input field 111d is the date of birth of the user, but the management server 10 calculates the age from the date of birth and supplies the nutrition. The data is sent to the reference amount database 30. Thereby, as shown in FIG. 2, the nutrient intake reference amount database 30 has an item of age.
In addition, as shown in FIG. 4B, the information input in the input field 112a is the user's competition item, but the management server 10 classifies the competition based on the competition item, and provides an estimated amount of nutrition intake. Send to database 30. Thereby, as shown in FIG. 2, the nutrient intake reference amount database 30 has items of competition classifications such as instantaneous and ball games. The processing of the body information and the competition information may be performed on the nutrient intake reference amount database 30 side.

When the button 113 described as “Acquire nutrient intake reference amount” is touched by the user's operation, information (nutrition requesting the management server 10 from the user terminal 20 to acquire the nutrient intake indication amount is received. A request for obtaining an approximate intake amount) is sent.
When the management server 10 receives the nutritional intake standard amount acquisition request from the user terminal 20, the management server 10 obtains the body information and the competition information corresponding to the user ID that transmitted the nutritional intake standard amount acquisition request from the nutritional intake standard amount database 30. get.
And the nutrient intake standard amount calculation part 12 of the management server 10 calculates the nutrient intake standard amount of the user using the information contained in body information and competition information.

Here, the method by which the nutrient intake reference amount calculation unit 12 calculates the nutrient intake reference amount will be described.
The nutrient intake guide amount calculation unit 12 calculates the nutrient intake guide amount based on information on each item included in the physical information and information on each item included in the competition information.

The nutrient intake guide amount calculation unit 12 calculates a reference intake guide amount (reference intake guide amount) based on the weight and basal metabolism of the user. The basal metabolic rate is an amount of energy per unit body weight necessary for the user to maintain his / her life, which is determined based on information such as the user's sex, age, and muscle mass. The nutrient intake reference amount calculation unit 12 calculates the total amount of energy necessary for the user to maintain life by multiplying the basal metabolic rate by the weight of the user, and based on the calculated total amount of energy. Calculate the reference intake standard amount. Thus, by calculating the reference intake standard amount based on the body weight and the basal metabolic rate, at least the intake necessary for maintaining life can be included in the reference intake standard amount.
However, the reference intake standard amount does not take into account the intensity of user activity (hereinafter referred to as activity intensity). For this reason, there is a case where the estimated intake amounts of the user who is exercising intensely and the user who is exercising lightly are calculated as the same amount.

  Therefore, in this embodiment, the nutrient intake reference amount calculation unit 12 corrects the reference intake reference amount with a correction value according to the user's situation. Specifically, the nutrient intake reference amount calculation unit 12 calculates the activity intensity of the user based on the user's physical information and the competition information, and uses the calculated activity intensity as a correction value as a reference intake guideline. Correct the amount.

  The nutrient intake guide amount calculation unit 12 calculates the intake intake amount of each of energy and nutrients as the nutrient intake guide amount. In this case, a reference intake standard amount is calculated for each of energy and nutrients, and each calculated intake standard amount is corrected with a correction value based on the activity intensity of the user. In this case, the correction value for the energy intake reference amount and the correction value for the nutrient intake reference amount may be the same correction value or different correction values. Further, the same correction value may be used for each nutrient, or different correction values may be used for the nutrient intake reference amount. Hereinafter, an example of a method in which the nutrient intake reference amount calculation unit 12 calculates the energy intake reference amount will be described.

  The nutrient intake reference amount calculation unit 12 calculates the energy intake reference amount of the nutrient intake reference amount by the following (Equation 1).

  Estimated energy intake = body weight x basal metabolic rate x activity intensity (Formula 1)

  In the above (Formula 1), the body weight is an element of physical information, and can be acquired from the information stored in the body weight item in the estimated nutrient intake database 30 shown in FIG. The basal metabolic rate is an element of physical information, and can be acquired from information stored in each item of gender and age in the estimated nutrient intake database 30 shown in FIG.

  The nutrient intake reference amount calculation unit 12 acquires the activity intensity based on each information of the competition classification, the period division, and the exercise amount which are elements of the competition information. For example, endurance-type and instantaneous-type competitions have greater activity intensity than technical and aesthetic competitions. Also, in the training period, the activity intensity is greater than in the game period and off period. In addition, when exercising five or more times a week, the activity intensity is greater than that of exercising once a week.

  The nutrient intake reference amount calculation unit 12 calculates the activity intensity based on the relationship between the competition classification, the period division, and the exercise amount, for example. For example, when the reference activity intensity is increased, the nutrient intake reference amount calculation unit 12 sets the activity intensity value to 1.0 or more, and when the activity intensity is not increased, the activity intensity is set to 1.0. To do. When the activity intensity is 1.0, the energy intake reference amount is the same as the reference energy intake reference amount. When the activity intensity is set to a value of 1.0 or more, the energy intake of the user is set so that the energy intake reference amount is larger than the reference energy intake reference amount in consideration of the user's activity intensity. It is the amount corrected for the intake standard amount.

  The nutrient intake reference amount calculation unit 12 determines the activity intensity according to the relationship between the period and the amount of exercise for each competition classification. For example, when a certain user X is in the endurance system, the amount of exercise is 5 times or more per week, and the period is in the training period, a range of activity intensity that can be set is calculated. The largest activity intensity (for example, 3.0) is set. In endurance competitions, energy consumption is higher than in other competition categories, and if the amount of exercise is more than 5 times a week, the physical activity level is high and the basal metabolic rate is high. This is because it is assumed that the activity intensity is higher than that in the off period and the energy consumption is large.

  On the other hand, the nutrient intake reference amount calculation unit 12 is set for the above-described user X even if the competition classification is endurance, or if the exercise amount is about once a week, even if the period is the training period. An activity intensity (for example, 1.0) smaller than the activity intensity is set. Even in endurance competitions, it is assumed that physical activity level is low and basal metabolic rate is low with exercise amount of about once a week, and activity intensity is low and energy consumption is low even during training period. Because it is.

As described above, in the present invention, the nutrient intake reference amount calculation unit 12 associates each of the competition classification, the period division, and the exercise intensity with the activity intensity, so that the competition classification, the period division, and the exercise quantity regarding the user are associated. It is possible to acquire the activity intensity suitable for the user from each information.
The competition classification can be acquired from the data stored in the competition classification item of the nutrient intake reference amount database 30 shown in FIG. The period division can be acquired from the data stored in the item of the period division of the nutrient intake reference amount database 30 shown in FIG. The amount of exercise can be acquired from the data stored in the item of amount of exercise in the nutrient intake reference amount database 30 shown in FIG.

  In the present invention, the nutrient intake standard amount calculation unit 12 may use the standard energy calculated as described above and the standard intake amount of each nutrient as they are as the standard intake amounts of energy and nutrients. The calculated reference energy and the estimated intake amount of each nutrient may be multiplied by a correction value based on the activity intensity to calculate the estimated intake amount of each of energy and nutrient. It may be used as an intake standard amount or may be obtained by multiplying this reference value by a correction value. In this case, the nutrient intake reference amount calculation unit 12 may calculate a correction value for each competition classification stored in the item of the nutrient intake reference amount database 30. Hereinafter, an example in which the nutrient intake reference amount calculation unit 12 calculates a correction value for each competition classification will be described.

  For example, when the competition classification is endurance competition, the nutrient intake reference amount calculation unit 12 sets a correction value of the nutrient intake reference amount so as to increase carbohydrates and minerals. In endurance competitions, there is a tendency to increase the amount of sweat and sweat from the usual practice, and the amount of sweat and sugar tends to be lost compared to other competitions. Because there is.

  Moreover, the nutrient intake standard amount calculation part 12 sets the correction value of a nutrient intake standard amount so that protein may be increased, when a competition classification | category is an instantaneous-type competition. This is because in the flash-based competition, strengthening of muscles and joints is important, and protein must be actively supplied.

  In addition, the nutrient intake reference amount calculation unit 12 sets a correction value of the nutrient intake reference amount so that the amount of iron increases when the competition classification is endurance or aesthetic competition. This is because endurance competitions tend to consume iron, and aesthetic competitions tend to cause anemia due to excessive weight loss, so it is particularly necessary to replenish iron.

  Moreover, the nutrient intake standard amount calculation part 12 can set the correction value of the nutrient intake standard amount using the period division information. For example, the nutrition intake reference amount calculation unit 12 reinforces protein, iron and other minerals, vitamins, etc. when the period information includes information indicating the injury period or rehabilitation period, carbohydrates, etc. Set the correction value to reduce. The nutrient intake reference amount calculation unit 12 may set the correction value of the nutrient intake reference amount using any one of the competition information only, the period information only, or both the competition information and the period information. .

  Note that, in the above, the case where the nutrient intake standard amount calculation unit 12 calculates the reference energy intake reference amount, the reference nutrient intake reference amount, and the activity intensity based on the relational expressions for calculating each. Although illustrated and demonstrated, it is not limited to this. For example, the nutrient intake guide amount calculation unit 12 may determine the energy intake guide amount, the nutrient intake guide amount, and the activity intensity on the basis of a table (not shown) that corresponds to each other. Specifically, the nutrition intake reference amount calculation unit 12 uses a data table (not shown) in which a reference intake amount is associated with each combination of the user's body weight and basal metabolic rate, and the intake of energy serving as a reference A reference amount may be determined. In addition, the nutrient intake standard amount calculation unit 12 uses a data table (not shown) in which each nutrient is associated with the intake standard amount for each body weight and basal metabolic rate of the user, and serves as a standard nutrient intake standard. The amount may be determined. The nutrient intake reference amount calculation unit 12 may determine the activity intensity using a data table (not shown) in which the activity intensity is associated with each combination of the competition classification, the period division, and the exercise amount.

FIG. 5 is an example of a display screen for the reference amount of nutrition intake of the user terminal 20.
When the user terminal 20 receives the nutrient intake guide amount from the management server 10 via the communication unit 23, the user terminal 20 displays the received nutrient intake guide amount via the display unit 25 as shown in the display screen 103 of FIG.
In the display screen 103, for example, the total intake energy as the energy intake reference amount, and the nutrient intake amount optimal for the user for each nutrient such as protein, lipid, carbohydrate, iron and vitamins as the nutrient intake reference amount Is displayed numerically. Each user can maintain the optimum nutrient intake amount by watching the estimated intake amount of each nutrient displayed on the display screen 103 and eating.
