The invention relates in general to an apparatus, method and data structure for providing dietary information to assist in the research, evaluation, and selection of dietary products, including food, drink, and drugs, based on information provided by system users.
In the past, dietitians and nutritionists prepared personalized menus for individuals. Planning nutritious and appealing menus is a daunting and time-consuming task for a physician, nurse or even a master dietitian. Moreover, individual counseling sessions or traditional group sessions do not allow for menu planning time. Despite the obvious benefits, it is currently cost prohibitive for many individuals and households to obtain menu guidance. Therefore, most individuals or facilities in need of planned menus must plan them manually on their own or with the use of the primitive software or websites that produce template or static menus.
Several patents and articles have been published in the dietary field. For example, U.S. Pat. No. 4,807,169 (to Overbeck), U.S. Pat. No. 5,673,691 (to Abrams et al.), and U.S. Pat. No. 5,983,200 (to Slotznick); Balintfy, J. L., “Menu planning by computer,” Communications of the ACM, 7:255-259 (1964); and Petot, G. J., et al., An Artificial Intelligence System for Computer-Assisted Menu Planning,” Journal of the American Dietetic Association, 98:1009-1014 (1998), each of which is herein incorporated by reference in its entirety, relate to dietary information generally. Each of these references has serious deficiencies and none provides the comprehensive research, data acquisition, analytical tools, data evaluation, and user interface/selection of the present invention.
The foregoing demonstrates that there is a need for an invention which allows an individual to obtain dietary information based on a variety of factors, including an individual's medical nutritional needs, specific medication(s) (which may have drug/nutrient interaction implications), cooking skills, food expense budget, food preferences (including, for example, favorite recipes), food allergies, life stage, and lifestyle.
The invention satisfies the need and avoids the drawbacks of the prior art by providing an apparatus, method and data structure that set forth an interactive venue for the procurement and analysis of a comprehensive aggregate of information relating to, but not limited to, diet, nutrition, medications, cooking skills, food budget, food preferences, allergies, life stage, and lifestyle. Access to the system of the invention greatly reduces the time and costs associated with the process of identifying specific foods, obtaining and compiling dietary information, analyzing the information, providing dietary advice, and procuring food for an individual, family or institution. As such, the invention provides an easy and reliable tool that combines a user-friendly interface with powerful databases and professional analysis to identify menu options that meet the needs of the user.
The invention relates to a knowledge-based system for personalized menu generation using various technologies for data manipulation to incorporate the information and expertise of professionals. In one aspect, the system may generate menus for individuals, households or groups and may search a database of recipes based on a set of inputs provided by the user and generated by the system. In a preferred aspect, a grocery list will be generated that may be printed and employed for traditional grocery shopping or may be utilized in conjunction with connections to on-line vendors.
According to one aspect of the invention, an apparatus for and a method of communicating dietary information between a user and a database are set forth. The apparatus and method may include the structure for and steps of storing dietary information on a database, searching the database for dietary information using specific criteria, and manipulating the information to provide a set of information. The set of information may be transmitted to the user or the user may be provided with a location on the database containing the information. System users may provide an assessment of the received dietary information by entering information into an evaluation form which may be accessed by future users. The apparatus and method may include assigning passwords to users to allow future use of the system.
In another aspect of the invention, a system for communicating dietary information contains a computer-readable memory for storing data for access by an application program and includes a data structure stored in the computer-readable memory. The data structure may include information used by the application program and may contain a plurality of personal data fields, anthropometrics fields, special metabolic needs fields, food preferences fields, health status fields, food allergies fields, life stage fields, dietary prescription fields, and cooking complexity fields. The application program may use the field values to provide a menu plan based on the manipulation of said plurality of fields by employing a combination of databases. In various aspects, a plurality of databases, such as a menu/recipe database, personal database, nutritional database and medication database, may be employed in varying combinations to compute a meal plan for a user.
The client machines 26 may be connected to the server 12 by communication links 28, and the external databases 30 may be connected to the server 12 by communication links 29. The communication links 28, 29 between the server 12 and the client machines 26 and between the server 12 and the external databases 30, respectively, may include a large variety of connections, including a telephone link, a hard-wired connection, a satellite link or other wireless connection, an Internet connection, a local area network (LAN), a wide area network (WAN), any combination of the preceding, or any other suitable type of connection. Multiple client machines 26 may communicate simultaneously with the server 12, and each connection may be by a different type of link, e.g., one connection may be by telephone while another may be by the Internet. Similarly, multiple external databases 30 may communicate simultaneously with the server 12, and each connection may be a different type of link as discussed above. As stated above, the server 12 connects to communication links 28, 29 via communication hardware 24.
The server 12 may communicate, via communication link 29, with a particular database 30 by a variety of communication protocols, including file transfer protocol (FTP), electronic mail (e-mail), transfer control protocol/Internet protocol (TCP/IP), ASCII, X-MODEM, Y-MODEM, KERMIT, any combination of the preceding protocols, or any other suitable type of protocol. The server 12 may gather information from a database 30 automatically, e.g., at regularly scheduled intervals, only in response to data requested from a client machine 26, or both automatically and in response to a request from a client machine 26. Depending on the nature of the information provided by a particular database 30, the connection between the server 12 and the particular database 30 may be “live” at all times or may be established intermittently.
After a link is established between the server 12 and a client machine 26, communication may take place via a variety of communication protocols, as described above with respect to communication between the server 12 and database 30. The software running on a client machine 26 that accesses information on the server 12 may be a known Internet browser such as Netscape Navigator or Internet Explorer or may be any other type of software suitable for transmitting information to and receiving information from the server 12.
In one embodiment, the server 12 is an ALPHA server. With this platform, CPUs, memory, networking capabilities, storage, and software may be modified as appropriate to meet specific requirements. The selection of a suitable server requires consideration of CPU speed as well as disk subsystem performance and network bandwidth. For example, a disk with a 7200 RPM rotational speed may be a suitable disk subsystem. Once the RAID is selected (RAID 0, 1, 2, 3, 4, or 5), the size of the database and its projected growth must be analyzed as part of the known design considerations.
The database 16 on the server 12 may be of any suitable type that may be used for large database applications. Oracle is an extremely powerful and flexible relational database system. Procedural Language/Standard Query Language (PL/SQL) is a sophisticated programming language used to access the Oracle database from various environments. Another preferred database that may be employed is Oracle8i. The Oracle8i database is useful for Internet applications and manages the content, data and files typically managed by an operating system. Oracle8i has a Java Virtual Machine, a native Java compiler, and Internet File System (iFS), which provides the ability to store, query, and manage a wide range of relational and non-relational data within the database. iFS, written in Java, allows users to store 164 data types, including spreadsheets, word processing documents, Web pages and e-mail, within the database and retrieve them either in native file format or in HyperText Markup Language (HTML) through a browser. iFS indexes each file automatically and gives users enhanced security, database search capabilities, backup and recovery. Other features in Oracle8i include WebDB, a environment run through a browser that enables developers to dynamically generate Web content and pages; SQLJ, a programming syntax that embeds SQL database statements into client or server Java code; and interMedia, a system for managing rich data types used over the Web. Of course, other database systems may be utilized according to the invention.
In a preferred embodiment, a user uses a client machine 26 to connect to the server 12 via a communication link 28. The user may then log onto the database 16. Optionally, a password may be required of the user. If a password is required and the user has not used the system previously, the user is given a password by the server 12 or is prompted by the system 10 to obtain a password from an administrator of the server 12. Next, the user must enter the previously obtained password. Additional steps for repeating a password request if the user enters incorrect data or for permitting the user to create a unique password are known. A user who has used the system previously has the option of editing or deleting information previously entered into the user's record.
After logging onto the server 12, a user may enter pertinent information into the database 16 concerning the type or types of information desired. As discussed below, a wide variety of data may be entered into database 16. The server 12 may be connected to one or more databases 16, 30. Once the information from one or more databases 16, 30 is entered into the database 16, a search may be performed using server 12 to identify information requested by a user. The server 12 may then format the requested information appropriately. Once the information is formatted, it may then be transmitted to a user at a client machine 26.

The fields may be provided in a convenient drop-down menu or toolbar. Of course, window contents and toolbar options may be modified by the user.
Selection of interview field 102 permits a user to engage a listing of personal data, anthropometrics, special metabolic needs, food preferences, health status, food allergies, life stage, dietary prescription, cooking complexity, meal plan override, and professional referral questions as is illustrated in interview screen 200 in
Selection of this week's menu field 106 permits a user to be presented with a list of meals for a seven-day period according to the principles of the invention as illustrated in
Weekly menu screen 300 may also include a display field 302 that displays all meals for the week based upon the user's responses to the interview questions, coded for personal food and health data as described above, and a Nutritional Database 51 that may be created by professionals and maintained on the system 10. In a preferred embodiment, the Nutritional Database 51 is coded for nutrient content and appropriate and complementary meal components.
In a preferred embodiment, a gauges field 303 may be included that provides information and alerts according the generated menu. For example, gauges field 303 may include calorie, cholesterol, sugar or other nutritional information to indicate that a user or users are meeting or exceeding limits established by interview responses or an individualized menu plan based on the interaction between the Menu/Recipe Database 53, Nutritional Database 51, and the Personal Database 52. Additionally, through the use of a Medication Database 54, that may be created by professionals and maintained on the system 10, gauges field 303 may indicate potential or actual drug/food contraindications so that a user may be alerted to negative interactions prior to adoption of a particular menu plan. In another preferred embodiment, the information utilized from the Medication Database 54 may be incorporated with the Nutritional, Personal and Menu/Recipe Databases 51, 52, 53, respectively, so that the displayed menu plan takes all databases into account automatically.
Selection of today's menu field 104 permits a user to be presented with a list of meals for a one-day period according to the principles of the invention as illustrated in
In a preferred embodiment, a user may select from a number of event-based meals. For examples, selection may be made from a variety of choices for events such as Thanksgiving, Christmas, Valentines Day, 4th of July, St. Patrick's Day, daughter's birthday party, son's graduation party, business meetings, and the like. The databases may also maintain records of these event-based meals so that a user may recall and duplicate acceptable meals, avoid redundant meals with the same guests, and eliminate unsuccessful meals. Additionally, the databases may keep a record of a user's meals over time so that meal recommendations take into consideration recent meals to prevent redundancy.
In another preferred embodiment, a user may select budget fields 305 or 405 on screens 300 or 400 to enter a daily, weekly, monthly, or event-based budget. This allows a user to utilize system 10 and grocer pricing to work backwards to create a menu plan having needed items that are within a given budget. In this manner, nutritionally and medically approved foods are provided that meet a user's budgetary constraints as well.
Selection of restaurants field 110 permits a user to be presented with a list of meals available at various restaurants according to the principles of the invention, as illustrated in
Selection of shopping field 114 may permit a user to be presented with a list of fields in preparation to obtain the items identified by the daily or weekly menu display according to the principles of the invention as illustrated in
Selection of inventory field 112 allows a user to facilitate the generation of a shopping list by employing inventory screen 700 according to the principles of the invention. As shown in
In one preferred embodiment, a user may select competitive bids field 609 or 705 and by following the prompts the user may enter the needed items for transmittal to a preselected pool of grocers. Each selected grocer has the opportunity to respond, such as via system 10 or via email, by providing a price and/or other terms for each of the needed items. In this manner, grocers can compete for a user's order. If the grocers are equipped for online and delivery orders, then a user may select the grocer of choice and have the needed items delivered automatically.
Selection of education field 116 may permit a user to be presented with an education screen 800 including information regarding nutrition education, health/wellness education, cooking skills, online kitchen craft, demonstrations of equipment usage, using portions, eating as a family, feedback from choices made, and personalized coaching as shown in

Selection of about e3squares field 122 provides a user with all pertinent information about system 10.
Selection of tracking field 140 permits a user to track personal information relating to both measured data, such as weight, cholesterol, blood pressure, and menu-based data, such as protein intake, calorie intake, and the like. In fact, a user may enter and track data of any nature by selecting enter data field 1001 and following the prompts for setting up a tracking option as is illustrated by tracking screen 1000. For example,
Selection of computations field 142 may allow a user to perform a number of calculations. As shown in
Regarding the depicted templates, forms and reports of the invention, it is understood that a fewer or greater number of fields may be employed by adding or subtracting choices or by consolidating or expanding choices as desired. Additionally, it is further understood that certain of the fields may substitute menu selections or a lookup table for text entry fields or vice versa, according to the design criteria of the application. Save, reset, forward, and back buttons may be used in combination with one or more of the templates, forms, and reports. A feedback submission field may be preferably provided so that users may convey assessment information relating to menu planning and the system 10 itself to the controller of the system 10, so that the system 10 may be continually improved.
In a preferred embodiment, the information displayed on the screens of the invention may be printed or stored off-line in a client machine 26, such as a personal computer, laptop, PDA or pen computer for retrieval at a later time. In one preferred embodiment, client machines 26 will include special computer terminals having bar code readers for entering purchased goods into system 10 to permit a user to create a record of purchases. Additionally, client machines 26, such as kiosks, may be located in grocery stores to permit “near” point-of-sale access to the dietary information in the system 10 and may also provide generic menus free of charge to users that have not provided interview responses.
Menu/Recipe Database 53 is scalable and may store individual and household menus for local, regional and international recipes. Additionally, the Menu/Recipe Database 53 may store food qualities such as color, texture, flavor, nutritional attributes, appropriateness for specific diets, cultural preferences, life stages, and scalability. A user may add favorite recipes to the Menu/Recipe Database 53 for selection at a later time. Additionally, a user may add, subtract or modify the amounts or ingredients in any of the recipes to accommodate the personal needs of the user. The Menu/Recipe Database 53 may consider the seasonal and regional variations in ingredients and recipes so that the menus generated by system 10 closely conform to the user's needs. The response to the cooking complexity field 209 may instruct the Menu/Recipe Database 53 to factor the cooking expertise level into menu planning. Meal patterns received from the personal database, e.g., a user or member eats cereal for breakfast everyday, may be considered by the Menu/Recipe Database 53. The Menu/Recipe Database 53 may make recommendations regarding vitamins, herbs and diet supplements. The Menu/Recipe Database 53 may consider individual plans from the personal database, e.g., organic, vegetarian, vegan, kosher. A feedback loop may also be provided that gives helpful hints while meal planning.
System 10 employs a variety of technologies that are integrated according to the principles of the invention. These technologies may include expert systems, case-based reasoning, rule-based reasoning, search engines, financial transaction capabilities, databases, networking web or servers, and data-mining systems. These technologies are employed to incorporate the knowledge and expertise of a physician, nutritionist, food preparer, and user by electronically programming information to produce explicit knowledge to be handled by intelligent software. Thus, the knowledge system of the invention provides comprehensive dietary information and facilitates the procurement of food, drink, and supplements, and provides a shopping cart to carry needed items to vendors. The system 10 makes the knowledge and expertise of a nutritionist available to a user by assessing a user's personal medical file and interview summary to provide a recommendation for the ultimate menu for health and lifestyle. For example, case-based problem solving may be used by system 10 to apply a prior solution to generate the solution to a new problem. System 10 has the capability to store users' cases and solutions to facilitate the resolution of similar future cases.
A host, designated A, is planning a meal for a plurality of guests, designated B-G, with the following criteria: B and C do not eat meat or poultry; C is allergic to milk products; D, E, and F are “meat-and-potatoes” people; and A's friend, G. Since it is tomato season, A wants to use tomatoes as a major ingredient in the meal. As A is planning the meal, he remembers:
A decides not to serve tomato tart and continues planning. Since it is summer, he decides that grilled fish would be a good main course. [Menu/Recipe seasonal memory.] But then remembers:
“Last time I tried to serve G grilled fish, she wouldn't eat it. I had to put hot dogs on the grill at the last minute.” [Time constraint memory.] This suggests to A that he should not serve fish, but he wants to anyway. He considers whether there is a way to serve fish that G will eat.
A remembers seeing G eat mahi-mahi in a restaurant. He recalls that the fish he previously served G was whole trout with the head on. The fish in the restaurant was a fillet and more like steak than fish. [Guest interview summary memory and Menu/Recipe substitutional memory.] A determines that he should serve a fish that is more like meat than fish and concludes that swordfish is acceptable. [The success/failure of the meal may be recorded and cross-referenced to each of the participants A-G.]
This example, or case, illustrates a typical real-life problem that knowledge, decision, and remembered cases can suggest a means of solving a new problem (e.g., suggestion of a main dish), to suggest how to adapt an appropriate solution. As the bracketed items emphasize, the solution requires reliance on a variety of data. System 10 simultaneously provides this information to thousands of users where each user enters different limiting criteria.
The previous case illustrates a manner in which a system, according to the principles of the invention, may be utilized.
First, there are at least two uses for this case: (1) it provides a condition for success when choosing a vegetarian main dish with tomatoes: choose tomato tart to feed vegetarians in the summer, and (2) it provides a condition for success when trying to accommodate a person who is allergic to milk when a main dish with cheese is being served. Thus, when trying to adapt a dish with cheese in it for someone who eats no milk products, use tofu as a cheese substitute.
Second, the case provides input to determine under what circumstances this case would be useful for constructing a solution: (1) when the goal is to choose a main dish, the dish is to be vegetarian, the dish is to include tomatoes, and the time is summer; and (2) when main dish has cheese as an ingredient, one or a few guests are allergic to milk products, and the goal is to accommodate those guests.
Third, descriptions of the case are translated into the vocabulary of the user, making them recognizable to the user. System 10 considers how data are structured and sets weighted values for each type of decision. System 10 also addresses the choice of structuring various data records. In the above case, there is a simple set of fields for representation of possible types of data: guest, host, cuisine, ingredients, preparation method, dishes (subdivided into salad, main dish, sides, beverage, dessert, and dessert-beverage), reasoning goal, constraints, season, results, and the like. Some of these fields have further substructure. For example, each dish may have several optional descriptors: cuisine, taste, texture, ingredients, preparation method, constraints. In a preferred embodiment, the system of the invention retains all possible cases and retrieves information and makes recommendations according to a unique user's inputs and constraints.
According to the invention, menus may be grouped and classified to user-defined groups and classes. Menus may be set up for multiple serving lines and months. Standard menus may be established and stored, individually or in cycles and assigned to later periods of times as needed by a particular user. Both menu calendars and menu lists may be created and printed. In one embodiment, the system databases are preloaded with all USDA items, brands and “team nutrition” recipes. In another embodiment, system 10 is connected to government databases that provide a variety of useful information employed by the invention, such as nutritional information, standards for breakfast and lunch for children, and the like.
System 10 may also compute nutrient composition for menus associated with an age group or range of grade levels for comparison to the USDA information and weighted nutritional analysis for a one- to seven-day menu cycle. System 10 may print cost analysis for a range of menu days, production recipes automatically scaled, pre-preparation summaries, recipe ingredient labels, and menus printed in a variety of formats.
