Definitions
- the present invention relates to a dietary evaluation system and a dietary evaluation method.
- Patent Document 1 discloses a urine analysis method for calculating the amount of specific component excreted by humans per day. In this urine analysis method, first, the amount of the first urine excreted by a person after waking up and the concentration of a specific component are measured, and the amount of the specific component excreted in the first urine after waking up is determined.
- the urine analysis method calculates the specific component excretion amount that a human excretes per day based on the converted prescribed time equivalent.
- the specific component is, for example, any one or more of sodium, potassium and calcium.
- Patent Document 2 discloses an ingredient intake measuring device including a data acquisition unit, a specific ingredient excretion equivalent calculation unit, a specific ingredient intake calculation unit, and an output unit. disclosed.
- the data acquisition unit determines, between the elapsed bedtime, which is the elapsed time from the last urination before the predetermined bedtime period to the first urination after the bedtime period, and the sleep elapsed time Urine data is obtained, including the amount of excreted urine and the concentration of specific constituents in the urine.
- the specific component excretion equivalent calculation unit calculates a specific component excretion equivalent, which is the amount of the specific component excreted by a human in a specified time period, from the acquired urine volume, specific component concentration, and predetermined specified time period.
- the specific ingredient intake calculation unit estimates the daily specific ingredient intake that a person takes in a day from the calculated specific ingredient excretion equivalent, and the output unit outputs the measurement result including the daily specific ingredient intake. do.
- the specific component excretion equivalent calculation unit calculates a specific component excretion equivalent, which is the amount of the specific component excreted by a human in a specified time period, from the acquired urine volume, specific component concentration, and predetermined specified time period.
- the specific ingredient intake calculation unit estimates the daily specific ingredient intake that a person takes in a day from the calculated specific ingredient excretion equivalent, and the output unit outputs the measurement result including the daily specific ingredient intake. do.
- Patent Document 3 discloses a urine component analyzer including a correlation storage section, a data input section, and a calculation section.
- the correlation storage unit stores the concentration ratio between the first specific component and the second specific component in one urine excreted by a human and 1 when all urine excreted by a human in one day is collected. It stores data representing the correlation between the concentration ratio between the first specific component and the second specific component in the total urine of the day.
- the data input unit inputs data representing the concentration ratio between the first specific component and the second specific component in one urine excreted by the subject.
- the calculation unit calculates the correlation stored in the correlation storage unit based on the concentration ratio between the first specific component and the second specific component in one urine sample of the subject obtained through the data input unit. is used to convert the concentration ratio between the first specific component and the second specific component in the total urine of the day when all the urine excreted by the subject in a day is collected as one. ask for It is stated that the concentration ratio between the two specific components in the whole urine excreted by the subject for one day can be easily obtained.
- Patent Document 4 urine having a correlation storage unit, a total urine volume acquisition unit, a data input unit, a first calculation unit, and a second calculation unit A component analyzer is disclosed.
- the correlation storage unit stores the concentration of the specific component in one urine excreted by a human and the concentration of the specific component in all urine excreted in one day when all the urine excreted by a human in one day is collected. It stores data representing the correlation between concentrations.
- the total urine volume acquisition unit acquires the total urine volume excreted by the subject in one day based on conversion or a database.
- the data input unit inputs data representing the concentration of the specific component in the urine excreted once by the subject.
- the first calculation unit calculates the subject's Assuming that all the urine excreted in a day is collected as one, the concentration of the specific component in the whole urine in a day is converted and obtained.
- the second calculation unit multiplies the concentration of the specific component in all urine for one day obtained by the first calculation unit by the total urine volume for one day obtained by the total urine amount obtaining unit, The excretion amount of the specific component in the total urine of the measurer for one day is calculated. As a result, it is possible to simply and accurately determine the excretion amount of the specific component in the whole urine of the person to be measured for one day.

Also, when dealing with two types of spot urine nutritional component indices, the sodium/potassium ratio and the urea nitrogen/creatinine ratio, four dietary evaluation patterns of comments related to salt, vegetables/fruits, and protein can be prepared. good. Furthermore, when dealing with two types of spot urine nutritional component indices, the magnesium/creatinine ratio and the urea nitrogen/creatinine ratio, four dietary evaluation patterns of comments related to fruit, seaweed, milk, and protein can be prepared. good.
- spot urine nutritional component indices may be appropriately selected from the four types of sodium/potassium ratio, magnesium/creatinine ratio, urea nitrogen/creatinine ratio, and sodium/creatinine ratio shown in FIG. Other nutrient indicators may be added.
- the nutritional status of humans can be evaluated from various perspectives. It can be evaluated from the minimum point of view.
- the dietary evaluation system and the dietary evaluation method according to the present invention use a single human spot urine to determine the balance of a human diet from the nutritional component index of a single human spot urine. It is useful as a system and method for evaluating and improving human dietary habits and dietary education, and using a single human spot urine to simply and overall evaluate human dietary habits It is effective as a dietary habit evaluation system and a dietary habit evaluation method.
