Description

本発明は、健康に関心の高い個人または食事療法を必要とする患者が食事をする際に、尿から排出される電解質に関する情報と食事によって取り込まれる電解質に関する情報に基づいて適切な飲食方法等を提示する食事指導支援装置に関するものである。   The present invention provides an appropriate eating and drinking method based on information on electrolytes excreted from urine and information on electrolytes taken in by meals when individuals who are highly interested in health or patients requiring dietary therapy eat. The present invention relates to a meal guidance support device to be presented.

近年、不適切な生活習慣が主な原因とされる高血圧症、高脂血症、糖尿病、肥満症などが生活習慣病として大きく注目されている。これらの病気は、一般の内科的な薬物などによる治療と異なり、生活習慣そのもの（飲食習慣、ストレスの蓄積や運動不足）の改善を行なうことが治療の中心となる。また、他の病気の治療が病院で行われるものが多い中、生活習慣病の治療は家庭での治療が中心となる場合が少なくない。   In recent years, hypertension, hyperlipidemia, diabetes, obesity and the like, which are mainly caused by inappropriate lifestyle habits, are attracting attention as lifestyle-related diseases. Unlike the treatment with general medical drugs, these diseases are centered on improving lifestyle habits (eating and drinking habits, stress accumulation and lack of exercise). In addition, while many other diseases are treated in hospitals, lifestyle-related diseases are often treated at home.

一方、飲食習慣に関しては、電解質（例えば、食塩）の摂取量は、１日当たり１０グラム以下と推奨されているが、管理栄養士等が指導している制限食をとっている患者でもない限り電解質の摂取量を正確に把握することは難しいのが現状である。また、食事日誌をつけることにより調味料や食材に含まれている電解質を含めて記録に残すことも可能であるが、一定期間在宅で正確な食事日誌をつけることは困難である。   On the other hand, with regard to eating and drinking habits, the intake of electrolytes (eg, salt) is recommended to be 10 grams or less per day, but unless the patient is taking a restricted diet as directed by a registered dietitian etc. It is difficult to accurately grasp the intake amount. In addition, it is possible to keep a record including the electrolytes contained in the seasonings and ingredients by attaching a meal diary, but it is difficult to keep an accurate meal diary at home for a certain period of time.

このため、尿中の電解質について尿中食塩測定用試験紙を用いる方法、尿量および電解質濃度を計測し、１日の電解質の***量から電解質の総摂取量を推定する方法（例えば、特許文献１参照）などが提案されている。
特開平８−７５７２７号公報 For this reason, a method of using a test paper for urinary salt measurement for electrolytes in urine, a method of measuring urine volume and electrolyte concentration, and estimating a total electrolyte intake from the amount of electrolyte excreted per day (for example, Patent Literature 1) is proposed.
JP-A-8-75727

最近では、ナトリウムイオン電極を使ったスープなどの液体中の電解質濃度計が市販されている。しかし、上記の電解質の総摂取量を推定する方法やスープなどの液体中の電解質濃度を測定する方法では、電解質過多の原因が食事内容のどの部分にあるのかを特定することは困難である。   Recently, an electrolyte concentration meter in a liquid such as a soup using a sodium ion electrode is commercially available. However, it is difficult to specify in which part of the meal content the cause of the excessive electrolyte is by the method for estimating the total intake amount of the electrolyte or the method for measuring the electrolyte concentration in a liquid such as soup.

そこで、本発明は、上記課題に鑑みてなされたものであり、電解質の摂取過多の原因が食事内容のどの部分にあるのかを特定し、これに基づいて適切な食事指導支援をすることが可能な食事指導支援装置等を提供することを目的とする。   Therefore, the present invention has been made in view of the above problems, and it is possible to identify which part of the meal content is responsible for excessive intake of electrolyte, and to provide appropriate meal guidance support based on this The purpose is to provide a simple meal guidance support device.

上記目的を達成するために、本発明に係る食事指導装置は、ユーザが排出する尿中の電解質量を測定する尿中電解質測定手段と、前記ユーザの食事内容のうち前記ユーザが飲食する液状食の電解質濃度を測定する液状食電解質測定手段と、前記液状食の量を示す情報を受け付ける液状食情報受付手段と、測定された前記液状食の電解質濃度と前記液状食情報受付手段により受け付けられた前記液状食情報とに基づいて、前記液状食の電解質量を算出する液状食電解質量算出手段と、計測された前記尿中の電解質量と前記液状食の電解質量との関係の強さを示す関係値を算出する関係値算出手段と、算出された前記関係値に基づいて、前記ユーザにおける尿中電解質量を増大させる主要因が前記液状食であるか否かを判定する主要因判定手段とを備える。   In order to achieve the above object, a meal instruction apparatus according to the present invention includes a urine electrolyte measuring means for measuring an electrolytic mass in urine discharged by a user, and a liquid food that the user eats and drinks among the user's meal contents. The liquid food electrolyte measuring means for measuring the electrolyte concentration of the liquid food, the liquid food information receiving means for receiving information indicating the amount of the liquid food, the electrolyte concentration of the measured liquid food and the liquid food information receiving means Based on the liquid food information, the liquid food electrolysis mass calculating means for calculating the electrolysis mass of the liquid food, and the strength of the relationship between the measured electrolysis mass in the urine and the electrolysis mass of the liquid food is shown. Relation value calculation means for calculating a relation value; and main factor determination means for determining whether or not the main factor for increasing the urinary electrolytic mass in the user is the liquid food based on the calculated relation value. Provided.

これにより、電解質の摂取過多の原因が食事内容のどの部分にあるのかを特定し、これに基づいて適切な食事指導支援をすることが可能となる。   As a result, it is possible to identify in which part of the meal content the cause of excessive intake of the electrolyte is, and to provide appropriate meal guidance support based on this.

なお、本発明は、上記食事指導支援装置における特徴的な構成手段をステップとする食事指導支援方法として実現したり、それらステップをパーソナルコンピュータ等に実行させるプログラムとして実現したりすることもできる。そして、そのプログラムをＤＶＤ等の記録媒体やインターネット等の伝送媒体を介して広く流通させることができるのは云うまでもない。   The present invention can be realized as a meal instruction support method having steps as characteristic constituent means in the meal instruction support apparatus, or can be realized as a program for causing a personal computer or the like to execute these steps. Needless to say, the program can be widely distributed via a recording medium such as a DVD or a transmission medium such as the Internet.

本発明の食事指導装置によれば、食事内容における電解質の摂取過多となる原因が、ユーザが飲食する液状の食事に起因しているかを判定することができる。   According to the meal instruction apparatus of the present invention, it is possible to determine whether the cause of excessive intake of electrolyte in meal contents is due to a liquid meal that the user eats or drinks.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、本発明について、以下の実施の形態および添付の図面を用いて説明を行うが、これは例示を目的としており、本発明はこれらに限定されることを意図しない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, although this invention is demonstrated using the following embodiment and attached drawing, this is for the purpose of illustration and this invention is not intended to be limited to these.

図１は、本発明に係る食事指導支援システム１００の概観を示す図である。図１に示されるように、食事指導支援システム１００は、制御装置１１０、尿中電解質測定装置１２０および液状食電解質測定手段である電解質濃度計１３０を備える。   FIG. 1 is a diagram showing an overview of a meal guidance support system 100 according to the present invention. As shown in FIG. 1, the dietary guidance support system 100 includes a control device 110, a urine electrolyte measurement device 120, and an electrolyte concentration meter 130 that is a liquid food electrolyte measurement means.

制御装置１１０は、例えば通信機能や各種インターフェース機能等を備えるパーソナルコンピュータである。制御装置１１０は、電解質濃度計１３０を介して測定した汁物（「液状食」ともいう。）メニューの電解質濃度と尿中電解質測定装置１２０を介して受信した尿量及び尿中電解質濃度とに基づいて、電解質の摂取過多の主要因が汁物メニューにあるか否かを判定する。   The control device 110 is a personal computer provided with, for example, a communication function and various interface functions. The control device 110 is based on the electrolyte concentration of the soup (also referred to as “liquid food”) menu measured through the electrolyte concentration meter 130 and the urine volume and urine electrolyte concentration received through the urine electrolyte measurement device 120. Thus, it is determined whether the main factor of excessive intake of the electrolyte is in the soup menu.

尿中電解質測定装置１２０は、尿中に含まれる電解質量を測定する装置であり、例えば測定端末１０と便器２０とを備える。この場合、採尿した尿の尿量および尿中電界質濃度を尿中電解質測定手段である測定部２１で測定し、測定端末１０のアンテナ１１を介してＢｌｕｅｔｏｏｔｈ等の無線で制御装置１１０に送信する。なお、ユーザは、操作キー１３を操作し、液晶ディスプレイ１２に測定結果を表示させることが可能である。   The urinary electrolyte measurement device 120 is a device that measures electrolytic mass contained in urine, and includes, for example, the measurement terminal 10 and the toilet 20. In this case, the urine volume and the urinary electric field concentration of the collected urine are measured by the measurement unit 21 which is a urinary electrolyte measurement means, and transmitted to the control device 110 by radio such as Bluetooth via the antenna 11 of the measurement terminal 10. . The user can operate the operation key 13 to display the measurement result on the liquid crystal display 12.

図２は、本発明に係る食事指導支援システム１００の機能構成を示すブロック図である。図２に示されるように、食事指導支援システム１００は、尿中電解質測定部１２０、電解質濃度測定部１３０および制御装置１１０を備える。さらに、制御装置１１０は、演算部１０３、判定部１０４、食事メニュー入力部１０５、表示部１０６および記憶部１０７を備える。なお、以下では、便宜上電解質として塩化ナトリウムを、電解質量として塩分量を想定することとする。   FIG. 2 is a block diagram showing a functional configuration of the meal guidance support system 100 according to the present invention. As shown in FIG. 2, the meal guidance support system 100 includes a urine electrolyte measurement unit 120, an electrolyte concentration measurement unit 130, and a control device 110. Furthermore, the control device 110 includes a calculation unit 103, a determination unit 104, a meal menu input unit 105, a display unit 106, and a storage unit 107. In the following, for convenience, sodium chloride is assumed as the electrolyte, and salt content is assumed as the electrolytic mass.

尿中電解質測定部１２０は、上記図１における尿中電解質測定装置１２０に相当し、尿量および尿中に含まれるナトリウム等の電解質濃度を測定し、尿量と電解質濃度から塩分量を算出する。   The urinary electrolyte measurement unit 120 corresponds to the urinary electrolyte measurement device 120 in FIG. 1, measures the urine volume and the electrolyte concentration of sodium and the like contained in the urine, and calculates the salt content from the urine volume and the electrolyte concentration. .

電解質濃度測定部１３０は、上記図１における電解質濃度計１３０に相当し、食事から摂取する電解質濃度を測定する。一般に食物は、汁物（例えば、みそ汁、スープ等）、固形物（例：ごはん、肉、魚等）および混合物（ラーメン、うどん等）に分類することができ、汁物と混合物（以下、これらをまとめて「汁物」と称する。）については、電解質濃度測定部１３０によってその塩分濃度を測定する。   The electrolyte concentration measurement unit 130 corresponds to the electrolyte concentration meter 130 in FIG. 1 and measures the electrolyte concentration taken from a meal. In general, food can be classified into soup (eg, miso soup, soup, etc.), solid (eg, rice, meat, fish, etc.) and a mixture (ramen, udon, etc.). In this case, the salt concentration is measured by the electrolyte concentration measuring unit 130.

液状食電解質量算出手段及び関係値算出手段として機能する演算部１０３は、尿中電解質測定部１２０および電解質濃度測定部１３０からの測定結果及び液状食情報受付手段である食事メニュー入力部１０５から受け付けた食事に用いた容器（カップ）の種類（即ち、飲食した食べ物の体積）に基づいて、両者の塩分量とそれらの関係の強さを示す関係値（具体的には、両者の塩分量の相関の度合いを示す相関値）を算出する（この場合の「相関値Ｒxy」は、尿中塩分排出量と塩分摂取量の共分散を尿中塩分排出量の標準偏差と塩分摂取量の標準偏差で割った値とする。）。例えば、ｎ日に亙り、尿中塩分排出量をｘ、塩分摂取量をｙとした場合の相関値Ｒxyは、（１）式で示される。

Figure 2006300782
The calculation unit 103 functioning as a liquid food electrolysis mass calculation unit and a relational value calculation unit receives the measurement results from the urinary electrolyte measurement unit 120 and the electrolyte concentration measurement unit 130 and the meal menu input unit 105 which is a liquid food information reception unit. Based on the type of container (cup) used for eating (ie, the volume of food eaten or consumed), the relationship between the salt content of both and the strength of the relationship (specifically, the salt content of both (Correlation value indicating the degree of correlation) (in this case, “correlation value Rxy” is the standard deviation of urinary salt output and standard deviation of salt intake) Divided by.) For example, the correlation value Rxy when the urinary salt excretion amount is x and the salt intake amount is y is expressed by equation (1) over the n days.
Figure 2006300782

主要因判定手段及びアドバイス提示手段として機能する判定部１０４は、算出された相関値に基づいて、摂取塩分量の過多およびその主要因となる食事等を判定し、ユーザの食事に対する指導内容を特定する。   Based on the calculated correlation value, the determination unit 104 that functions as a main factor determination unit and an advice presentation unit determines an excessive amount of salt intake and meals that are the main factor, and specifies the content of guidance for the user's meal To do.

なお、上記相関値に限らず、尿中塩分排出量と塩分摂取量の差や尿中塩分排出量に対する塩分摂取量の比に基づいて電解質摂取過多の主要因を判定してもよい。   In addition, the main factor of excessive electrolyte intake may be determined based on the difference between the urinary salt discharge amount and the salt intake amount and the ratio of the salt intake amount to the urinary salt discharge amount without being limited to the correlation value.

食事メニュー入力部１０５は、マウスやキーボード等を備え、ユーザから食事内容や食事に用いた容器の種類、測定日時、測定対象（飲食した者）の氏名等を受け付ける。表示部１０６は、ユーザから食事内容等に関する入力を受け付けるための画面を表示したり、ユーザに対する指導内容等を表示する。データ蓄積手段である記憶部１０７は、例えばハードディスクやＤＶＤ等であり、過去に測定した、摂取した電解質量や尿中の電解質量を記憶する。   The meal menu input unit 105 includes a mouse, a keyboard, and the like, and receives from the user the contents of the meal, the type of container used for the meal, the measurement date and time, the name of the measurement target (person who eats and drinks), and the like. The display unit 106 displays a screen for accepting an input regarding meal contents or the like from the user, or displays guidance contents or the like for the user. The storage unit 107 serving as data storage means is, for example, a hard disk or a DVD, and stores the ingested electrolytic mass or the electrolytic mass in urine measured in the past.

体内の電解質量は、浸透圧の関係から、一定値を取る事が知られている。そのため、口から摂取した電解質量は、ほぼ同量が体外に排出される。体外への排出のされ方としては、通常、尿と汗が知られているが、汗はマラソン等、相当量の発汗を伴うスポーツなどでなければ尿に比べて無視できる量である。   It is known that the electrolytic mass in the body takes a constant value from the relationship of osmotic pressure. Therefore, almost the same amount of electrolytic mass ingested from the mouth is discharged out of the body. Usually, urine and sweat are known as methods of excretion outside the body, but sweat is a negligible amount compared with urine unless it is a sport involving a considerable amount of sweat such as marathon.

また、１日の尿***量は、１日における腸管からの吸収量に等しく、尿中電解質量の中でもナトリウム、カリウム、塩素は、経口摂取量がほとんどそのまま尿中に排出されるとみなしてよい（これらの内容に関しては、日本腎臓学会誌２００２年 ４４巻１号「水電解質異常」参照されたい）。従って、経口摂取により取り込まれた塩分等の電解質は、尿中に排出され、その量を計測する事により、実際に摂取した量を計測することが可能となる。   The daily urinary excretion is equal to the amount absorbed from the intestinal tract in the day, and sodium, potassium, and chlorine among the urinary electrolysis mass may be considered to be excreted almost directly in the urine. (For these contents, refer to Journal of Japanese Society of Nephrology, Vol. 44, No. 1, “Abnormalities of water electrolyte”). Therefore, electrolytes such as salt taken up by oral ingestion are excreted in urine, and the amount actually taken can be measured by measuring the amount thereof.

また、塩分量を計測するには、２４時間蓄尿が望ましいが、第６２回日本公衆衛生学会総会において、夜間尿（就寝後から、起床時１回目までの尿）は、２４時間蓄尿と相関があり個人の健康管理に応用可能である事が報告されている。（日本公衆衛生雑誌第５０巻・第１０号２１２頁 「家庭での食塩摂取量測定装置の開発とその応用」参照）。このため、夜間尿を用いて２４時間畜尿と同等の効果が得られる。   In order to measure the amount of salt, 24-hour urine accumulation is desirable. However, at the 62nd Annual Meeting of the Japanese Society of Public Health, night urine (from bedtime until the first wake-up) is correlated with 24-hour urine accumulation. It has been reported that it can be applied to personal health management. (See Japan Public Health Magazine Vol. 50, No. 10, p. 212 “Development and application of a device for measuring salt intake at home”). For this reason, the effect equivalent to 24 hours livestock urine is obtained using nighttime urine.

図３は、食事メニュー入力部１０５を介してユーザから食事内容に関するデータを取得する際の表示部１０６に表示される画面例である。図３には、測定対象の食事を表す食事名、電解質濃度計１３０の値（％）、測定した容器（カップ）の大きさ、測定日時および飲食した者が入力すべき項目であることが示されている。なお、図３には示されていないが、測定対象外（固形物）の食事名についても受け付けることとする。   FIG. 3 is an example of a screen displayed on the display unit 106 when data regarding meal contents is acquired from the user via the meal menu input unit 105. FIG. 3 shows that the name of the meal to be measured, the value (%) of the electrolyte densitometer 130, the size of the measured container (cup), the measurement date and time, and items that should be entered by the person who eats or drinks. Has been. In addition, although not shown in FIG. 3, suppose that it accepts also about the meal name outside a measuring object (solid substance).

上記の場合、例えばおわん（小）なら１００ｃｃ、おわん（中）なら１５０ｃｃのように、予め容器毎の標準的な容積を定義しておくこととする。また、１日に摂取した汁物が複数ある場合は、それらすべての汁物の総和をその日の摂取電解質量とする。尿中の電解質量についても同様に測定する。   In the above case, a standard volume for each container is defined in advance, for example, 100 cc for bowl (small) and 150 cc for bowl (medium). Moreover, when there are a plurality of soups ingested in a day, the sum of all the soups is taken as the ingested electrolysis mass for that day. The electrolytic mass in urine is measured similarly.

以下、本発明について、具体的な数値を用いながら、更に詳細な説明を行う。
図４は、尿中塩分量と汁物内塩分量について９日間測定を行った結果の一例である。この例では、便宜上、前日における一回の食事で次の日に１回採尿を行った場合を想定している。なお、図５は、上記図４に示す尿中塩分量と汁物内塩分量についての相関関係を視覚的に示す図である（さらに、後述する相関値についても示している。）。 Hereinafter, the present invention will be described in more detail using specific numerical values.
FIG. 4 is an example of the results of measurement for 9 days for the urinary salt content and the salt content in the juice. In this example, for the sake of convenience, it is assumed that urine is collected once on the next day with one meal on the previous day. FIG. 5 is a diagram visually showing a correlation between the urinary salt content and the soup salinity shown in FIG. 4 (further, the correlation values described later are also shown).

図６は、上記図４の測定結果を用いて（さらに、上記（１）式を用いて）、相関値Ｒxyを算出する過程を示した図である。さらに、図６には、尿中塩分量と汁物内塩分量との相関値に関する判定基準の一例が示されている。   FIG. 6 is a diagram showing a process of calculating the correlation value Rxy using the measurement result of FIG. 4 (and further using the above equation (1)). Furthermore, FIG. 6 shows an example of a determination criterion regarding the correlation value between the urinary salt content and the salt content in the soup.

図６に示す例では、相関値Ｒxyは「０．１９４３５５７７５」であり、尿中塩分量と汁物内塩分量には「ほとんど相関なし」が認められるため、尿中電解質測定部１２０で測定された尿中塩分量が多い場合は、例えば「みそ汁、スープ等から取る塩分は適切ですが、これら以外の焼き魚などから取る塩分量が多いようですのでご注意下さい！」等のアドバイスをすることが可能である。逆に、もし、尿中塩分量が多い割に尿中塩分量と汁物内塩分量の相関が高い場合は、体内に取り込まれた塩分量は汁物から摂取されていると推定されため、この場合は、「みそ汁、スープ等から取る塩分が多いようです。飲む量を少なくするか、香辛料等を使って塩分の利用を控えて下さい！」等のようなアドバイス内容とする。なお、相関値の値に対応付けたアドバイス内容を予め記憶部１０７に記憶しておくこととする。   In the example shown in FIG. 6, the correlation value Rxy is “0.194355775”, and “almost no correlation” is recognized between the urinary salt content and the salt content in the soup, and therefore, measured by the urine electrolyte measurement unit 120. If the amount of salt in the urine is high, you can give advice such as “Salt taken from miso soup, soup, etc. is appropriate, but note that the amount of salt taken from other grilled fish seems to be high!” It is. Conversely, if there is a high correlation between the urinary salinity and the salinity in the juice for a large amount of urinary salinity, it is estimated that the salinity taken into the body is ingested from the soup. The content of the advice is such as “It seems that there is a lot of salt taken from miso soup, soup, etc. Please reduce the amount of drink or use salt with spices etc.!”. It is assumed that the advice content associated with the correlation value is stored in the storage unit 107 in advance.

次に、本発明に係る食事指導支援システム１００の動作について説明する。
図７は、食事指導支援システム１００の動作の流れを示すフローチャートである。 Next, the operation of the meal guidance support system 100 according to the present invention will be described.
FIG. 7 is a flowchart showing the operation flow of the meal guidance support system 100.

最初に、特定のユーザについての尿中電解質量と汁物の食事に含まれる電解質量の測定期間とその測定データを特定する（Ｓ３０１）。次に、演算部１０３は、上記特定された測定データについて相関値を算出する（Ｓ３０２）。   First, the measurement period and measurement data of the electrolysis mass in the urine and the electrolysis mass contained in the soup meal for a specific user are specified (S301). Next, the computing unit 103 calculates a correlation value for the specified measurement data (S302).

この後、判定部１０４によって、尿中電解質量と汁物の食事に含まれる電解質量の相関が高いと判定された場合は（Ｓ３０３：Ｙｅｓ）、「汁物内の電解質が問題」である旨のアドバイスを表示部１０６に提示する（Ｓ３０５）。一方、尿中電解質量と汁物の食事に含まれる電解質量の相関が低いと判定された場合は（Ｓ３０３：Ｎｏ）、「固形物内の電解質が問題」である旨のアドバイスを表示部１０６に提示する（Ｓ３０４）。   After this, if the determination unit 104 determines that the correlation between the urine electrolytic mass and the electrolytic mass contained in the soup meal is high (S303: Yes), the advice that the electrolyte in the soup is a problem Is displayed on the display unit 106 (S305). On the other hand, when it is determined that the correlation between the urinary electrolytic mass and the electrolytic mass contained in the soup meal is low (S303: No), advice indicating that “the electrolyte in the solid matter is a problem” is displayed on the display unit 106. Present (S304).

なお、上記の実施の形態において、尿中電解質量（例えば、尿中塩分排出量）が予め定めておいた規定値より高い場合に、上記相関値を算出することとしてもよい。   In the above embodiment, the correlation value may be calculated when the urinary electrolytic mass (for example, urinary salt excretion) is higher than a predetermined value.

以上のように、本発明によれば、***される塩分として尿中電解質の測定結果とユーザが摂取する塩分として汁物に対する電解質濃度計からの結果に基づいてその相関を計算することにより、食事制限を受けている高血圧患者などにおいて、塩分摂取量を知ることができると同時に、食事内容の中で塩分摂取に関連の深い食事が、ユーザが飲食する液状食であるのか、固形物の食事であるのかを判定することができ、食事制限を受けている人にとって、作り方や食べ方を含めてどのように食事に気をつければ良いかという指針を得ることができる。   As described above, according to the present invention, the dietary restriction is calculated by calculating the correlation based on the measurement result of the urinary electrolyte as the excreted salt and the result from the electrolyte concentration meter for the soup as the salt taken by the user. In patients with hypertension, etc., it is possible to know the amount of salt intake, and at the same time, the meal content closely related to salt intake is a liquid food that the user eats or drinks, or a solid meal It can be determined, and for those who have dietary restrictions, it is possible to obtain guidelines on how to take care of meals, including how to make and eat.

本発明は、塩分摂取制限を受けている患者のためのパーソナルコンピュータ等を用いた食事制限支援装置や食事制限支援方法として有用である。   INDUSTRIAL APPLICABILITY The present invention is useful as a meal restriction support device or a meal restriction support method using a personal computer or the like for a patient who has received salt intake restriction.
