Abstract

A process for evaluation of an individual'"'"'s food choices based upon selected factors and dietary guidelines is disclosed. The DINE System provides a method and apparatus which allows an individual to determine how well or poorly the person is eating. The invention analyzes the food an individual eats and determines certain predictor and follower nutrients that will give rise to an assessment of how a person'"'"'s diet matches with various dietary guidelines established by governmental and/or other entities. The invention provides the results of the analysis to the individual complete with messages regarding over or under consumption of key nutrients so that the individual can correct the diet thereby resulting in better eating habits. The invention also gives the individual a "score" by which the person can immediately assess how well he or she is doing with respect to the various guidelines. The higher the number the better the diet.

Claims

1. A computer system for evaluating and analyzing a user'"'"'s diet, comprising:

(a) a computing device having a memory;

(b) an input device for entering information regarding the user'"'"'s actual dietary intake into the memory;

(c) a data base in the memory for storing the information;

(d) a nutrient base in the memory for storing consensus dietary guidelines relative to nutrients consumed by the user;

(e) a knowledge base in the memory having rules for manipulating the information in the data base to provide an organized historical record of the user'"'"'s dietary intake and a recommended future diet for the user;

(f) an application program, for execution in the computing device, for applying the rules in the knowledge base to the information in the data base and the guidelines in the nutrient base and for generating the organized historical record and the recommended future diet;

(g) a result base in the memory for storage of the organized historical record and the recommended future diet by the application program; and

(h) means for presenting the contents of the result base to the user, under the direction of the application program;

(i) the organized historical record including an analysis of the user'"'"'s actual dietary intake categorized according to predictor nutrients; and

(j) the recommended future diet including a listing of particular foods suggested for consumption by the user.

2. The computer system of claim 1, wherein the means for presenting the contents of the result base is a display device.

3. The computer system of claim 1, wherein the means for presenting the contents of the result base is a printer.

4. The computer system of claim 1, wherein:

(a) the application program further compares the contents of the data base to the content of the nutrient base and generates a message for each nutrient consumed by the user, the message stating whether the estimated consumption by the user was below, in excess, or within the guidelines stored in the nutrient base; and

(b) each message is stored in the result base.

5. An apparatus for evaluating and analyzing a user'"'"'s diet comprising:

(a) means for recording information regarding a user'"'"'s historical dietary intake;

(b) means for entering the information into a computer;

(c) means for evaluating, with the aid of the computer, the historical dietary intake to estimate actual amounts of nutrients consumed by the user for a time period;

(d) logic means for comparing the estimate of actual amounts of nutrients consumed by the user for the time period to recommended ranges of predictor nutrient consumption for the time period; and

(e) output means for generating, based on the information entered and the comparison of the estimate of actual ranges of nutrients consumed by the user for the time period to the recommended amounts of predictor nutrient consumption for the time period, a dietary intake plan which, if complied with, would make the user'"'"'s estimate of actual amounts of nutrients consumed for the time period correlate more precisely with the recommended amounts of predictor nutrient consumption for the time period;

f) the dietary intake plan listing particular foods suggested for consumption by the person.

6. The apparatus of claim 5 wherein the output means further generates messages stating whether the estimate of actual amounts of nutrients consumed by the user was within or outside the recommended ranges of nutrient consumption.

7. A method of evaluating a person'"'"'s dietary nutritional intake, comprising the steps of:

a) recording information regarding the person'"'"'s complete actual dietary intake;

b) entering said information into a computer;

c) evaluating, with the aid of the computer, the person'"'"'s complete actual dietary intake to estimate actual amounts of nutrients consumed by the person for a particular time period;

d) comparing, with the aid of the computer, the estimate of actual amounts of nutrients consumed by the person for the particular time period with a recommended range of amounts of nutrient consumption for the particular time period; and

e) generating, based on the information entered and the comparison of the estimate of actual amounts of nutrients consumed by the person for the particular time period with the recommended amounts of nutrient consumption for the particular time period, a dietary intake plan which, if complied with, would make said person'"'"'s said estimate of actual amounts of nutrients consumed for said particular time period correlate more precisely with said recommended range of amounts of nutrient consumption for said particular time period;

f) the dietary intake plan listing particular foods suggested for consumption by the person; and

g) wherein the step of evaluating the person'"'"'s historical dietary intake includes the step of manipulating the person'"'"'s actual dietary intake to provide an organized historical record of the person'"'"'s dietary intake, the organized historical record of the person'"'"'s dietary intake providing an analysis of the person'"'"'s actual dietary intake categorized according to predictor nutrients.

8. The method of claim 7, in which the predictor nutrients are selected from the group of nutrients consisting of protein, saturated fat, monounsaturated fat, polyunsaturated fat, complex carbohydrates, dietary fiber, sugar, cholesterol, sodium, potassium, vitamin A, vitamin C, iron, calcium, and phosphorus.

9. The method of either claim 7 or claim 8, in which said recommended amounts of nutrient consumption are derived from dietary intake guidelines issued nationally within the United States of America.

10. The method of claim 7, further including the step of generating, based on the information entered and the comparison of the estimate of actual amounts of nutrients consumed by the person for the particular time period with the recommended amounts of nutrient consumption for the particular time period, a dietary intake score which indicates a degree to which the person'"'"'s organized historical record correlates with the recommended amounts of nutrient consumption for the particular time period.
