Bibliography (includes reliable food and nutrient data sources). _____________________________________________________________________ INTRODUCTION -3- NUTRIENT PURPOSE AND FEATURES -------------------- NUTRIENT is a program written in IBM BASICA version 2.00 (PCjr requires Cartridge BASIC). It was written for the layman or health professional who wants to analyze an individual's food intake (diet) for nutrient adequacy. It is intended to accomplish this thru two categories of data entry by the program operator (you). First, personal data such as name, date of food intake, age, etc.; and second, food intake data such as food number and quantity eaten. ADEQUACY: regarding adequacy of nutrient intake, this is up to the individual. NUTRIENT analyzes one's food intake based on the accuracy of the personal data and food intake data entered. In addition, the analysis is meant for only healthy individual's in the U.S. population since it is based on the Recommended Dietary Allowances (RDA) of the Committee on Dietary Allowances of the Food and Nutrition Board, National Academy of Sciences. The RDA according to this committee are considered "to be adequate to meet the known nutritional needs of practically all healthy persons." However, there are limitations. The RDA were intended for population groups and not individual's. The RDA are estimates which exceed the requirements of most individual's. In general, if one were to take in less than the recommended amount of certain nutrients, his diet would not necessarily be inadequate. However, there is evidence that if one's nutrient intake consistently falls below the RDA, the risk of nutrient deficiency increases. On the other hand, exceeding the RDA by two to three times may be tolerated with most nutrients. However, it is not recommended that an individual consume excessive amounts of certain nutrients such as vitamins A and D, and certain trace minerals. Features: - Economical: NUTRIENT is software written with the end user in mind as well as the author. The program is offered at a reasonable price, and the user has the opportunity to review, and establish the value of the program for his need or interest prior to purchase. In turn, the author has the assistance of the user in the distribution of the program. - Individualized Analysis of Food Intake: NUTRIENT will analyze the diet of healthy individual's in all stages of the life cycle, from infancy through old age (I sometimes feel I'm at both extremes). - Multiple Day Analysis: 3 days of 45 foods each day are permitted to be entered. - 700 Food Database: The main database is a database of food names and their nutrient content. This is called FOODFILE. It can be customized by entering your own food preferences by using the routine called ADD A FOOD. FOODFILE is expandable to a size only limited by the disk capacity and speed of your machine. That is, large databases may require a hard disk ( but we're talking big ) and a RAM disk to improve search and sort speed. However, the current disk space will allow you to increase FOODFILE to 1100 foods. _____________________________________________________________________ INTRO (Purpose & Features) -4- NUTRIENT PURPOSE AND FEATURES (cont'd) - 27 Nutrients: There are 27 nutrient values for most foods, including some not often evaluated by other programs, such as cholesterol and alcohol. Of course alcohol is not considered a nutrient or dietary substance essential for humans. However, it is included with the nutrient listings for the sake of continuity. - Food Groups: NUTRIENT categorizes foods by food groups to enable one to select foods that are close to the one actually eaten, in its nutrient content and/or general characteristics. - Daily Averages: Receive a display and/or printout of the average daily nutrient intake for up to three days. This average is then compared to the 1980 RDA (expressed as Percent of RDA). - Printouts: Produced for an individual's Food Intake Analysis, including a simple graph, and comments on low and high nutrient intakes. You can print out individual food values; or all foods in the database by food group; also printout the entire Foodfile which will be a necessary reference for each person's food intake data entry. - Display: Besides printouts, you will be able to display a simple graph of an individual's Food Intake Analysis; individual food values; foods by food group; and the entire Foodfile. - Documentation: What you are now reading, READNUT1.DOC + READNUT2.DOC should be 51 pages. - Bibliography: A list of references used in the writing of NUTRIENT are provided for your referral. Handbook No. 8 and its revisions is the suggested reference of choice if you want to add foods to the current database. - Source Code: The IBM Basic code is provided for those who might find it useful as a teaching tool. _____________________________________________________________________ INTRO (Purpose & Features) -5- NUTRIENT STARTUP --------------------------------------------------------------------- DISTRIBUTION DISK FILES ----------------------- The following files should be on your distribution disk. If they are not, contact whoever distributed NUTRIENT to you, or contact Nutrition Quest c/o Robert Savryk at the address listed above in the introduction. FOODFILE METRO DAT ENERGY DAT RDA DAT CHILD DAT NUTRIENT BAS DSPLYNUT BAS SORTNUT BAS READNUT1 DOC READNUT2 DOC A brief description of each file can be found in APPENDIX A. DISK SETUP ---------- Your Working Copy disk will need to be a double-sided/double-density diskette, and formatted for 9 sectors, to include the operating system DOS 2.0+ (using the /S parameter of the DOS FORMAT command). Also include its equivalent version of BASICA.COM. Only the first 8 files on the Distribution Disk need to be copied to your Working Copy Disk. Of course you can also add a batch file to load BASICA and NUTRIENT, but that's up to you. See your version of the IBM DOS manual to carry out the formatting of your Working Disk, and copying the Distribution Disk files to it. Regarding data files, NUTRIENT creates Food Intake Analysis files for individual's food intake. It also writes data to, and erases data from FOODFILE; therefore, the disk containing these files should not be write-protected. STARTING NUTRIENT ----------------- First, make a Working Disk according to the directions in DISK SETUP. Second, put the disk in your default drive (usually drive A). Third, once you see on your monitor the DOS A> prompt, type BASICA NUTRIENT. That's it. Please enjoy. _____________________________________________________________________ STARTUP -6- NUTRIENT DOCUMENTATION/USER'S GUIDE -------------------------- The documentation you are now reading can be printed or displayed. Print using: Word Processor: using a word processor may give better page formatting of READNUT.DOC. Try these settings: PAGE: width 8 1/2" height 11" TEXT: width 7" left margin 1/2" right margin 1" height 11" top margin 0" bottom margin 0" DOS: if using the disk operating system, at the A> prompt, set your printer at the top of the page, and type: COPY READNUT1.DOC PRN: and COPY READNUT2.DOC PRN: Display using: Word Processor: see Print above. DOS: using DOS to display to the monitor, at the A> prompt type: MORE<READNUT1.DOC This will display the text one screen at a time. However, the MORE filter command must be on your disk. To simply display the text with continuous scrolling, use: TYPE READNUT1.DOC Which you probably already used to type this out; so, what's new? _____________________________________________________________________ STARTUP -7- NUTRIENT SCREENS --------------------------------------------------------------------- INTRODUCTION/DIRECTIONS ----------------------- Initial Display Screens ----------------------- The first screen you will encounter is a welcome screen. At the bottom of this screen is a disk drive prompt: Which Disk Drive for Personal Data files (A, B, C or ...)? The Personal Data files are created when you run the Food Intake Analysis routine. They contain a description of the individual as well as his food intake data. At the above prompt, ENTER a single letter to indicate which Disk Drive you want the files to be written. It is suggested that you use a disk drive other than the one containing the distribution files (main program and data files). If the main files are on drive A, then ENTER the letter B or C, etc.. This suggestion is made only if your default drive does not have the capacity to hold several additional files from 7K to 23K each. The next screen is a menu of two choices: 1 - Directions 2 - Main Menu Please choose a number (1 or 2)? Choose a selection by entering the number 1 or the number 2. 1 - Directions On selecting #1, you will see this screen: INTRODUCTION/DIRECTIONS 1. SYSTEM REQUIREMENTS - NUTRIENT runs on: IBM-PC/PCjr/PC-DOS 2.0+/1 Disk drive (320k)/128k RAM, Printer (EPSON MX-80 or compatible), Monitor (monochrome or color). If your system is IBM compatible, NUTRIENT may also run. 2. FOODFILE - This is the main data file. A printout of FOODFILE is necessary. Access it from the Main Menu when done with this screen. 3. PROMPTS - There will be a prompt line at the bottom of various screens (F1 HELP, etc.). Use the function keys for your control. 4. READNUT.DOC - This is a text/documentation file. Please read for more detailed instruction. 5. INPUT - Two types of data are used: i. Personal Data ii. Food & Quantity Data DO NOT WRITE PROTECT DATA DISK. 6. HELP - to access help routines, press key: F1 7. PRINT THIS SCREEN - by pressing keys: Shft-PrtSc Press space bar to continue ... _____________________________________________________________________ INTRO/DIRECTIONS -8- NUTRIENT The above INTRODUCTION/DIRECTIONS screen, and the two-choice menu can be bypassed by adding the following line to NUTRIENT.BAS (be sure the NUTRIENT.BAS file is in memory and not a file that was chained to during NUTRIENT's execution): 717 GOTO 940 then type: SAVE"NUTRIENT NOTE: This modification to NUTRIENT is for your own convenience, and is not permitted on a copy distributed to another user. Please comply since the above screen supplies important information for the proper running of NUTRIENT. NUTRIENT'S MENU --------------------------------------------------------------------- 2 - MAIN MENU On selecting #2 of the 2-choice menu of the initial display screen, (if it was not bypassed) the following screen will be displayed: NUTRIENT'S MENU 1 - FOOD INTAKE ANALYSIS 2 - ADD A FOOD 3 - DELETE A FOOD 4 - CHANGE A FOOD 5 - DISPLAY: A FOOD/FOODFILE/ANALYSIS 6 - PRINT: A FOOD/FOODFILE/ANALYSIS 7 - HELP 8 - EXIT NUTRIENT CHOOSE A NUMBER FROM 1 - 8? If you make a choice other than a number from 1 through 8, you will see this message: CHOOSE ONLY A NUMBER FROM 1 - 8 PLEASE The computer will wait patiently, even forever until a correct number is reentered. _____________________________________________________________________ NUTRIENT'S MENU -9- NUTRIENT FOOD INTAKE ANALYSIS --------------------------------------------------------------------- 1 - FOOD INTAKE ANALYSIS PERSONAL DATA ------------- On selecting #1 from NUTRIENT'S MENU, you will see the first screen of the FOOD INTAKE ANALYSIS routine. It looks like this: FOOD INTAKE ANALYSIS (Personal Data) Please enter the following: NAME (First Last): F1 HELP F10 EXIT You should now enter the personal data for the individual whose diet you want analyzed. If you press the ENTER key, you will be returned to NUTRIENT'S MENU. Otherwise, enter a first name or initial, followed by a space, then the last name. NUTRIENT uses the NAME to store food intake analysis data; therefore, if analyzing the diets of persons with similar names, ie, family members, use FIRST NAMES with unique FIRST INITIALS. Instead of: JOHN DOE and JAMES DOE Use : SENIOR DOE and JUNIOR DOE Or : S. DOE and J. DOE Press ENTER when finished with the NAME. NUTRIENT then displays: DATE: (MM-DD-YY): Enter a two digit month. For example, 01 or 09 or 12. Then enter the day as 1 or 2 digits, then the two digit year. Separate each by dashes "-", or slashes "/", or by using spaces " ". This date should be the date of the individual's food intake. It will later be used in combination with their name to locate their last data file. Press ENTER when finished. NUTRIENT then displays: ADULT, CHILD or INFANT (A, C or I): NUTRIENT classifies the following population groups: ADULT is 19 years of age or older CHILD is 18 years of age down to 2 years inclusive INFANT is less than 2 years _____________________________________________________________________ FOOD ANALYSIS (Personal Data) -10- NUTRIENT PERSONAL DATA (cont'd) Therefore, if within the ADULT years, enter an A; if a child, then enter the letter C; or I if an infant. Press ENTER when finished. NUTRIENT then displays: AGE (years): AGE (months): Enter the age in years if an adult or child, and in months if an infant. Press ENTER when finished. NUTRIENT then displays: SEX (M or F): Enter the individual's sex as M if male, or F if female. Press ENTER when finished. If F is entered, NUTRIENT then displays: PREGNANT, LACTATING, BOTH or NO (P, L, B or N): Enter: P if pregnant L if breast feeding B if pregnant and breast feeding N if neither pregnant nor breast feeding Press ENTER when finished. If P is entered, NUTRIENT then displays: No. of pregnant weeks: Enter the number of week's the individual has been pregnant. If L is entered, NUTRIENT displays: No. of lactating months: Enter the number of months's the individual has been breast feeding. If B is entered, NUTRIENT will display both the pregnant weeks and lactating months prompts, one at a time. If N is entered, or if the sex was entered as M for male, NUTRIENT displays: WEIGHT (lbs.): Enter weight in pounds, either whole pounds or in decimal fractions of pounds. For example, 101 or 100.7 or 101.3, and so on. If P for pregnant was previously entered, then NUTRIENT displays: Prepregnant weight: Enter the individual's weight prior to pregnancy, in pounds. Press ENTER. NUTRIENT next displays: HEIGHT (inches/no shoes): Enter the individual's height in inches without shoes, whether an adult or child. If an infant, NUTRIENT will display: LENGTH (inches/no shoes): As for adults and children, enter the infant's length (measured in the suppine position from the crown of the head to the soles of the feet, knees unbent, with a reliable measuring board) in inches without shoes. Press ENTER, and NUTRIENT will display the last personal data entry: _____________________________________________________________________ FOOD ANALYSIS (Personal Data) -11- NUTRIENT PERSONAL DATA (cont'd) FRAME: Small, Medium or Large (S, M or L): This entry is usually an estimate, unless you have been measured by a reliable source. It is a measure of body frame based on usually one of two methods, that is, elbow breadth or wrist circumference. Body frame is not a measure of abdominal girth, height or weight. If you estimate an individual's body frame without a specific measuring device, consider the bone structure of the elbow or wrist. Enter the individual's body frame as either small, medium or large using S, M or L respectively. Press ENTER. NOTE: One final note on personal data entry. A complete personal profile is necessary, i.e., NAME, AGE, SEX, HEIGHT, WEIGHT, etc. You must enter all personal data or errors may occur. HELP/EXIT Before we continue, a brief comment on the prompts at the bottom of the screen is in order. F1 HELP F10 EXIT These two prompts will be seen on the bottom line of many screens. F1 represents function key F1. If displayed, you can press it at any time and be taken to the HELP routines. F10 represents function key F10. When displayed, you can press it at any time and be taken to the previous menu, or to the main menu (NUTRIENT'S MENU). Further explanation can be found in the respective sections HELP and EXIT on page 42. CORRECTIONS With the ENTER key, you can correct data you have entered to the program. First, before typing in data on your current line, press ENTER. This will backup the cursor to the previous line; keep pressing the ENTER key to keep backing up. Second, once at the data you wish to correct, simply type over it. However, there is one drawback. You must retype each succeeding data entry. If you recognized your error just after ENTERing it, you only have to backup once and retype data once. _____________________________________________________________________ FOOD ANALYSIS (Personal Data) -12- NUTRIENT DAILY ESTIMATED ACTIVITY LEVEL ------------------------------ Now to continue, if the individual's data that has been entered represents a nonpregnant adult, then NUTRIENT displays: DAILY ESTIMATED ACTIVITY LEVEL 1 - Sedentary 2 - Lightly active 3 - Moderately active 4 - Heavily active Choose a number This screen represents the daily estimated physical activity of the individual. Physical activity is only one of three factors contributing to man's energy requirements. The other two are basal metabolism, and food metabolism. NUTRIENT uses your personal data (age, sex, height and weight) in conjunction with your activity level, to estimate your daily energy requirements, measured in calories. Your job is to select from the 4 choices. Examples of each activity category may help: 1 - Sedentary: seated and standing activities, sewing, ironing, truck/auto driving, laboratory work, typing, playing musical instruments. 2 - Lightly active: walking on level ground at 2.5-3 mph, garage work, carpentry, electrical trades, tailoring, restaurant work, cannery workers, clothes washing, shopping with light loads, golfing, sailing, table tennis, volleybal. 3 - Moderately active: walking at 3.5-4 mph, weeding and hoeing, plastering, loading and stacking bales, scrubbing floors, shopping with a heavy load, bicycling, skiing, tennis, dancing. 4 - Heavily active: walking with a load uphill, chopping down trees, pick and shovel work, climbing, basketball, swimming, football, running (short to middle distances). Exceptionally heavy activities include: bicycle racing, cross-country skiing, marathon racing. Keep in mind, no one usually spends 24 hours a day in one activity. Therefore, when you select an activity level, consider what activity level is participated in for the most hours each day, or estimate what the average would be of energy expense for a typical day that is comprised of various levels of activity. You be the judge, but be realistic. For example, if the individual sleeps 8 hours, sits at a desk 8 hours, sits watching TV, eating dinner, and with the paper for another 4 hours, works on a garage project for 2 hours, uses 1 hour daily in hygienic practices such as bathing and dressing, and finishes their 24 hour day with a 1 hour jog, he is not engaged in heavy activity but probably sedentary, since he spends most of his time in sitting activities. _____________________________________________________________________ (Daily Estimated Activity Level) -13- NUTRIENT DAILY ESTIMATED ACTIVITY LEVEL (cont'd) Make your selection and press ENTER. If your choice is not a number from 1 to 4, NUTRIENT will take a sedentary stance and sit waiting patiently. On ENTERing a correct choice, NUTRIENT then displays: PLEASE WAIT During this short wait, several arrays are being dimensioned to hold food and nutrient data. _____________________________________________________________________ (Daily Estimated Activity Level) -14- NUTRIENT FOOD INTAKE DATA ---------------- Thereafter, NUTRIENT displays: FOOD INTAKE SCREEN (Number of days to analyze(1 to 3)? NUTRIENT now waits for you to enter the number of days of food intake you want analyzed. This must be a number from 1 to 3. If you enter a different number, you will see: Choose a number between 1 & 3, please Number of (Food Intake) days to analyze? Now press an appropriate number and then the ENTER key. NUTRIENT will display: FOOD INTAKE (DAY #) FOOD QTY NO. DESCRIPTION UNITS EATEN --------------------------------------- ? ? F1 HELP F10 EXIT ENTER = END OF DAY This is the food intake data screen; you will be seeing a lot of this screen. Let's take a look at its parts. The first line displays the number (#) of the day's food intake you are currently ENTERing. The next three lines, or heading, display the food intake data that will be entered below it, either by the computer or you. The question marks represent data to be entered by you. And the bottom line displays three prompts. FOOD NO. refers to the number of the food found in the FOODFILE database. This database can be printed out by going to the main menu (NUTRIENT's MENU) and selecting the PRINT routine, which is choice 6. Each food is represented by a FOOD NO.. You will use that number to access foods through all of NUTRIENT's major routines. Now, you will find the cursor under FOOD NO.. I have used a ? above to indicate that when you see the cursor, it is your turn to ENTER data. Key in the food number and press the ENTER key. If the data record, that represents the FOOD NO. entered, is empty, NUTRIENT will display this message on the same line as the FOOD NO.: 1234 Record no. 1234 is empty, try again The message will be erased, then you can enter another FOOD NO.. If this record holds food data, the computer will take its turn and enter a: DESCRIPTION This is the Food Description such as MILK/WHOLE. It will also enter the UNITS (household measure) for that food found in the FOODFILE database. Then it is your turn again. _____________________________________________________________________ (Food Intake Data) -15- NUTRIENT FOOD INTAKE DATA (cont'd) QTY EATEN You will now enter the quantity eaten of the food described. Enter only a number. The number should be a multiple of the UNITS number. For example, if the UNITS displayed are 1 CUP, and 1 cup of the food was eaten, then enter the number 1. If 1.25 cups were eaten, then enter number 1.25. Easy huh? Be careful, because the UNITS displayed for a food may be large. For example, ALMONDS/ RAW has UNITS of 10 EACH. Therefore, if you ate 8 almonds, then you would enter .8 for QTY EATEN; if 10 almonds, then 1 for QTY EATEN. If you enter the number 10 for QTY EATEN, this represents 100 almonds eaten (10 x 10 EACH = 100). So you need to enter multiples or fractions of the UNITS number (8/10 EACH = .8). See APPENDIX B - TABLE OF EQUIVALENTS for help in converting your QTY EATEN to decimal fractions or multiples of the common UNITS. To ERASE the entire line and start over, while the cursor is under the QTY EATEN heading and no number has yet been keyed, press the ENTER key. You can now enter a new FOOD NO.. Erasing the entire line may be necessary if you keyed in the wrong FOOD NO., or the DESCRIPTION displayed was not what you expected. If numeric data has been entered, and you don't want to use the food described, simply erase the numbers keyed and press ENTER. The FOOD NO., DESCRIPTION, and UNITS will be erased, and not calculated into the day's totals. NOTE: To help in keeping a Food Record, a sample FOOD INTAKE RECORD & WORKSHEET is provided in APPENDIX C. This will be handy to have at your meals to record your food intake, and then by your keyboard while keying-in the Food Intake Screen data. F1 HELP This is the HELP prompt; by pressing Function Key F1, at anytime, you will be taken to the HELP routines. They are intended to be brief but helpful in entering data to a particular screen, or choosing from a menu. F10 EXIT This is the EXIT prompt; by pressing Function Key F10, at anytime, you will be taken to the particular routine's prior menu, or to NUTRIENT's MENU. ENTER = END OF DAY This is, you guessed it, the END OF DAY prompt. If you have finished ENTERing FOOD NO.'s for a particular day, while the cursor is under the FOOD NO. heading, press the ENTER key. NUTRIENT will then display: CALCULATING DAY # NUTRIENT TOTALS .....WAIT..... which means, NUTRIENT is calculating the nutrient totals for that day's (#) food intake. There is a WAIT while the totals are calculated, and then written to the individual's data file on disk. _____________________________________________________________________ (Food Intake Data) -16- NUTRIENT FOOD INTAKE DATA (cont'd) If there are additional days' food intake to be entered, the program will then return you to the FOOD INTAKE (DAY # +1) screen. You will continually be returned to the FOOD INTAKE screen as long as there are more days' to be analyzed. Once done calculating the last day's food intake, NUTRIENT will again display: FOOD INTAKE ANALYSIS (Personal Data) Please enter the following: NAME (First Last): which is the Food Intake Analysis screen you began with. Now you can enter another individual's data, or by pressing the ENTER key you will exit to the main menu (NUTRIENT's MENU). _____________________________________________________________________ (Food Intake Data) -17- NUTRIENT ADD A FOOD --------------------------------------------------------------------- 2 - ADD A FOOD On selecting #2 from NUTRIENT'S MENU, you may or may not see this message: FOODFILE IS FULL Press F1 for HELP This message is only seen if there is no more space in FOODFILE to add new foods. Then, if you press function key F1, you will be taken to the HELP routines. An explanation that the FOODFILE is full will be displayed, with the two options of either deleting foods from the database, or expanding the database. ENTER FOOD DATA --------------- However, if FOODFILE is not full, you will see the first screen of the ADD A FOOD routine. It looks like this: ADD A FOOD ENTER DATA WITHIN BRACKETS [ ]: Food Description [ ] Food Group [ ] Amount (No.+Unit) [ ] Weight (g) [ ] --------------------------------------------------------------------- Water (g) [ ] Thiamin (mg) [ ] Food Energy (kcal) [ ] Riboflavin (mg) [ ] Protein (g) [ ] Niacin (mg) [ ] Total Fat (g) [ ] Vitamin B-6 (mg) [ ] Carbohydrate (g) [ ] Folacin (mcg) [ ] Crude Fiber (g) [ ] Vitamin B-12 (mcg) [ ] Calcium (mg) [ ] Vitamin A (IU) [ ] Iron (mg) [ ] Vitamin E (IU) [ ] Magnesium (g) [ ] Saturated Fat (g) [ ] Phosphorus (mg) [ ] Monounsaturated Fat (g) [ ] Potassium (mg) [ ] Polyunsaturated Fat (g) [ ] Sodium (mg) [ ] Cholesterol (mg) [ ] Zinc (mg) [ ] Alcohol (g) [ ] Ascorbic Acid (mg) [ ] F1 HELP F10 EXIT Press TAB to goto next data item You can now begin to add a new food (of your choice) to the database FOODFILE. First, let's take a look at the major parts of this screen. ADD A FOOD is of course the title of this screen; the next line: ENTER DATA WITHIN BRACKETS [ ]: is an instruction to key-in your food's data within the brackets []. The screen has been designed to try and prevent data entry at places other than between the brackets. If you go around those safeguards, your on your own. _____________________________________________________________________ ADD A FOOD (Enter Food Data) -18- NUTRIENT ENTER FOOD DATA (cont'd) Food Description [ ] The next line is the Food Description; the cursor will initially be found here. Key in the new food's description (within the brackets). You are given 20 spaces, and it is suggested that you use a method of describing the food, or nomenclature similar to what has already been used in the database FOODFILE. Take a look at your FOODFILE printout. Placed first, you will see the food's group or type or category. For example: BREAD or BEEF or MILK or DRINK, etc. Of course it is not always possible to place a food into a clearly identified or distinctive group, as in BAMBOO SHOOTS which you might want to place in the vegetable group. But if you preceded the name with: VEGETABLE, then VEGETABLE/BAMBOO SHOOTS would take up more than 20 spaces, thereby limiting other descriptors. Next, you might want to key in the food preparation method, i.e., /RAW, /COOKED, /BAKED, etc. You will notice that a slash separates the major division's of the description. This is not necessary; any separator can be used. It does make it easier to read, and might be continued for continuity. Perhaps the best method is to study FOODFILE's FOOD DESCRIPTION's and try to follow its lead. Using the suggested references of food data in the Bibliography (APPENDIX G) can be extremely helpful also. It is possible to key in a Food Description that is already in the database. If that happens, this message is displayed: [SAMPLE FOOD ] has already been added After a short time, the message will be erased. Then reenter your Food Description, but modified to be unique. ABBREVIATIONS: Because the Food Description is limited to 20 characters, abbreviations are necessary. In APPENDIX D is a list of the abbreviations used in the FOODFILE database. Once you have keyed-in the Food Description, press the TAB key to move the cursor to the next data item. Food Group [ ] Amount (No.+Unit) [ ] Weight (g) [ ] This next line requires three pieces of information: food group, food units, and food weight. The units and weight will be found in your reference books, or on the food's Nutrition Label. Food Group [ ] The group is up to you to determine. Of course the group in which to place a food may be obvious, as with bananas or breads or meats or milk. However, some foods defy grouping. For instance, what food group do you place alcoholic beverages into? Since they may not even be considered a food by some, we have added five groups to the traditional Four Food Groups. These nine groups can be found in APPENDIX E with a breakdown of each into subgroups. _____________________________________________________________________ ADD A FOOD (Enter Food Data) -19- NUTRIENT ENTER FOOD DATA (cont'd) Enter a 2-letter Food Group code by following these guidelines: The first letter is the first letter of the Food Group itself. For instance, use D for the DAIRY/MILK group. The second letter is determined by the subgroup. For instance, the DAIRY/MILK group has a subgroup called NONFAT. Therefore, you would use N as the second letter, if the food falls into the nonfat subgroup. MILK/NONFAT would have the Food Group code of DN. Press TAB to continue. Amount (No.+Unit) [ ] The units are entered between the Amount brackets. Examples would be: 1 GAL, 1 CUP, 10 EACH, 1 SM, 1 MED, 1 LG, 1 SL, 1 PC, 1 TBSP, 1/2 PC, etc.. This is the basic unit that the food's nutrient data is recorded, either in FOODFILE, on food labels (1 svg = 1 oz), or in reference books of food tables. The food tables in reference books usually list the units under the heading: Approximate Measure and Weight. Key in a maximum of 6 characters, and press TAB to go to the next data item. Weight [ ] The weight should be recorded in GRAMS. As mentioned above, in the previous paragraph, the gram weight is found in food tables under the heading: Approximate Measure and Weight, and on food labels next to Serving Size. If the weight is in ounces, you convert ounces to grams by multiplying by 28.4, since 1 ounce = 28.4 grams. Key-in a maximum of 3 digits for the gram weight, and press TAB. NUTRIENT DATA The next major category of data is the food's nutrient data. There are 27 consecutive entries from water through alcohol. Each entry requires from 3 to 5 digits; this includes the decimal point if necessary. Press TAB to move from one nutrient to the next. If your source of nutrient data (found on food labels or in food tables) lists the nutrient value as 0 (zero), then key in 0. If there is no value listed, or a dash (-), or the word trace (tr) is listed, then leave blank. In this case, there may be a lack of reliable data, although the nutrient is thought to be present in a measurable amount; or, the nutrient's value is not measurable. Whether nutrient data is keyed-in or not, you can continue to the next item by pressing TAB. Press TAB to goto next data item The last line of the ADD A FOOD screen displays the TAB prompt, which I'm sure your familiar with by now ... Oh, your not? Well, the TAB key is the only way to move from one data item to the next. You will remember, at the start of this screen, the cursor was first located within the Food Description brackets. If you pressed the ENTER key, you received a discourteous beep or bell. This is because the ENTER key is reserved, while using the ADD A FOOD and CHANGE A FOOD screens as a signal to NUTRIENT. This will be explained shortly. _____________________________________________________________________ ADD A FOOD (Enter Food Data) -20- NUTRIENT ENTER FOOD DATA (cont'd) If you have come to the last data item (Alcohol), and press TAB, the following line is displayed near the bottom of the screen: Press ENTER if ok (press TAB to change data) The ENTER key, if pressed now, is the signal to NUTRIENT that your data entries are OK, that is, they are correctly entered. If you press ENTER, your newly ADDed food and its data will be saved in the database FOODFILE. MAKE CORRECTIONS ---------------- However, if you have found errors in your entries, then by pressing the TAB key now, the cursor will be moved to the end of the Food Description. To change data, use the BACKSPACE key. That is the only key that will work. It is a safeguard to prevent other data, or the screen's format from being changed, and from erroneous data being entered to NUTRIENT. TAB will again move the cursor from item to item. And once the cursor is past the last entry (Alcohol), the ENTER key will signal NUTRIENT that the data is to be saved. Once the data is saved, the following message is displayed: ADD ANOTHER FOOD (Y or N)? Your choices, of course are Y (YES) or N (NO). Pressing Y will clear the screen and present a fresh ADD A FOOD screen, for your new food entries. If N is pressed, you will be returned to the main menu (NUTRIENT's MENU). One other feature of the ADD A FOOD screen: F1 HELP F10 EXIT The last line of the ADD A FOOD screen displays the HELP and EXIT prompts, which are accessed by pressing their respective Function key. SOURCE OF FOOD DATA A comment about your sources of food data is in order. Part of the accuracy of the Food Intake Analysis depends on the reliability of the data entered to NUTRIENT's database FOODFILE. It is suggested that this data be obtained from two sources: 1. FOOD LABELS of major food manufacturers and distributors. These labels are found on many food packages, and use the heading: NUTRITION INFORMATION PER SERVING:. 2. FOOD TABLES of reliable sources. Several of these food tables can be found in the reference books listed in APPENDIX G. _____________________________________________________________________ ADD A FOOD (Make Corrections) -21- NUTRIENT DELETE A FOOD --------------------------------------------------------------------- 3 - DELETE A FOOD On selecting #3 from NUTRIENT's MENU, this screen is displayed: DELETE A FOOD Enter Food Number to Delete (0 to end)? There are two choices here. If you key-in a 0, and press ENTER, this screen will be erased and NUTRIENT's MENU will be displayed. In other words, you have been exited from the DELETE A FOOD routine. Your other choice is to ENTER a FOOD NO.. If this is done, the following is displayed: SAMPLE FOOD Delete (Y or N)? If SAMPLE FOOD is the food you want deleted, ENTER the letter Y. The screen will now display: SAMPLE FOOD Delete (Y or N)? Y ** Deleted ** NUTRIENT will now move the cursor back to the original line: Enter Food Number to Delete (0 to end)? Again, you can enter a food number to delete, or enter 0 to END the DELETE A FOOD routine, and return to the main menu. If SAMPLE FOOD is not the food you want deleted, ENTER the letter N. The screen will now display: SAMPLE FOOD Delete (Y or N)? N ** NOT DELETED ** NUTRIENT will now move the cursor back to the original line: Enter Food Number to Delete (0 to end)? Again, you can enter a food number, or the number 0. If a number is entered that is greater than the maximum number of records in the database, this message is displayed: Enter Food Number to Delete (0 to end)? 2001 Food Numbers are from 1 to ### - Try Again The ### represents the maximum record number of the current database. The message will be erased, and you can enter another Food No.. _____________________________________________________________________ DELETE A FOOD -22- NUTRIENT DELETE A FOOD (cont'd) If a Food No. is entered and no data is found at that record's location, the following message is displayed: Enter Food Number to Delete (0 to end)? 650 FOOD NUMBER 650 's record is empty - try again The message will be erased, and you can enter another Food No.. Or, as with other major screens, the F1 and F10 function keys can be pressed to receive HELP or to EXIT the DELETE A FOOD routine and return to the main menu. F1 HELP F10 EXIT _____________________________________________________________________ DELETE A FOOD -23- NUTRIENT CHANGE A FOOD --------------------------------------------------------------------- 4 - CHANGE A FOOD On selecting #4 from NUTRIENT's MENU, this screen is displayed: CHANGE A FOOD Enter Food Number to Change (0 to end)? As with the other main menu routines, the FOOD NO. is the key to receiving food and nutrient information from NUTRIENT. Simply ENTER a valid Food No.. One of three things will happen. First, if you entered the number of a record which had no data, this message is displayed: Enter Food Number to Change (0 to end)? 650 Food Record is empty - try again Shortly, the message will be erased & you can enter another Food No. Second, if you entered a number which is beyond the range of the maximum number of records in the current database, this message is displayed: Enter Food Number to Change (0 to end)? 2001 Food Numbers are from 1 to ### - Try Again The ### represents the maximum number you can use. The message will be erased and you can try again. CHANGE FOOD DATA ---------------- Third, if you entered a valid Food No. and the record contains data, you will see this screen: CHANGE A FOOD ENTER DATA WITHIN BRACKETS [ ]: Food Description [ ] Food Group [ ] Amount (No.+Unit) [ ] Weight (g) [ ] --------------------------------------------------------------------- Water (g) [ ] Thiamin (mg) [ ] Food Energy (kcal) [ ] Riboflavin (mg) [ ] Protein (g) [ ] Niacin (mg) [ ] Total Fat (g) [ ] Vitamin B-6 (mg) [ ] Carbohydrate (g) [ ] Folacin (mcg) [ ] Crude Fiber (g) [ ] Vitamin B-12 (mcg) [ ] Calcium (mg) [ ] Vitamin A (IU) [ ] Iron (mg) [ ] Vitamin E (IU) [ ] Magnesium (g) [ ] Saturated Fat (g) [ ] Phosphorus (mg) [ ] Monounsaturated Fat (g) [ ] Potassium (mg) [ ] Polyunsaturated Fat (g) [ ] Sodium (mg) [ ] Cholesterol (mg) [ ] Zinc (mg) [ ] Alcohol (g) [ ] Ascorbic Acid (mg) [ ] F1 HELP F10 EXIT Press TAB to goto next data item _____________________________________________________________________ CHANGE A FOOD (Change Food Data) -24- NUTRIENT CHANGE FOOD DATA (cont'd) This is the same screen as used in the ADD A FOOD routine. It will require the same key entries, BACKSPACE, TAB, and the ENTER key. To begin, the cursor will be at the end of the Food Description. To change data, use the BACKSPACE key. To safeguard data, it was explained in the ADD A FOOD routine (Enter Food Data section) that this is the only key that will work. Pressing TAB will move the cursor from item to item. This instruction is found on the last line: Press TAB to goto next data item Once the cursor is moved past the last entry (Alcohol), pressing the ENTER key will signal NUTRIENT that the data changed is to be saved. MAKE CORRECTIONS TO CHANGES --------------------------- However, if errors are discovered in your changes, the process of making changes can be repeated (ad nauseum), until you get it right, by pressing TAB to correct the data. These instructions for pressing ENTER or TAB to save or correct data respectively, is found in the following message that will appear at the bottom of the screen: Press ENTER if ok (press TAB to correct data) To review, once the cursor is at the end of the line above, pressing ENTER will save the data, and the following message is displayed: CHANGE ANOTHER FOOD (Y or N)? If you enter an N, for NO, you will be returned to the main menu. If you enter a Y, to change another food, the screen will be cleared and the initial message is presented: CHANGE A FOOD Enter Food Number to Change (0 to end)? ENTER a valid Food No. and the Change A Food screen will fill with the food's data, then the change process described above can be repeated. One other feature of the CHANGE A FOOD screen: F1 HELP F10 EXIT The last line of the CHANGE A FOOD screen displays the HELP and EXIT prompts, which are accessed by pressing their respective Function key. _____________________________________________________________________ (Make Corrections to Changes) -25- NUTRIENT DISPLAY: A FOOD/FOODFILE/ANALYSIS --------------------------------------------------------------------- 5 - DISPLAY: A FOOD/FOODFILE/ANALYSIS On selecting #5 from NUTRIENT's MENU, this screen is displayed: --------------------------------------------------------------------- DISPLAY SCREEN DISPLAY OPTIONS: 1 - FOOD(s) 2 - FOODFILE 3 - FOOD INTAKE ANALYSIS Choose a number please F1 HELP F10 EXIT --------------------------------------------------------------------- FOODS ----- You have entered the DISPLAY routine which will display (not print) to your monitor three options. The first option will display a single food and its nutrient data, or display a food group. 1 - FOOD(s) Selecting the #1 option of DISPLAY SCREEN will produce this screen: --------------------------------------------------------------------- DISPLAY FOOD(s) DISPLAY a: 1 - FOOD 2 - FOOD GROUP Choose a number please F1 HELP F10 EXIT --------------------------------------------------------------------- 1 - FOOD On selecting #1 of DISPLAY FOOD(s), this screen is presented: _____________________________________________________________________ DISPLAY FOOD(s) -26- NUTRIENT FOOD(s) (cont'd) --------------------------------------------------------------------- DISPLAY A FOOD Enter Food Number to display (0 to end)?

If the Food No. entered is valid and its record contains data, the food corresponding to that Food No. will be displayed with its nutrient values. The cursor then returns to the Enter Food Number ... line and awaits another Food No. entry or a 0. You can continue to enter food numbers indefinitely since, you know, the computer is very untiring. 2 - FOOD GROUP On selecting #2 of DISPLAY FOOD(s), this screen is presented: --------------------------------------------------------------------- DISPLAY FOOD GROUP 1 - DAIRY/MILK 5 - PROTEIN/MEATS 2 - VEGETABLES 6 - OILS/FATS 3 - FRUITS 7 - SWEETS 4 - BREADS/STARCHES 8 - COMBINATION 9 - MISC/OTHER Choose a number F1 HELP F10 EXIT --------------------------------------------------------------------- _____________________________________________________________________ DISPLAY FOOD(s) -27- NUTRIENT FOOD(s) (cont'd) ENTER the number of the Food Group you want displayed. The only acceptable numbers are from 1 to 9. These nine food groups and their respective subgroups are listed in APPENDIX E; therefore, only the DAIRY/MILK group and its subgroups will be presented here. 1 - DAIRY/MILK On entering #1 of the DISPLAY FOOD GROUP screen, you will see a screen of the subgroups of the DAIRY/MILK group: --------------------------------------------------------------------- DISPLAY DAIRY/MILK 1 - NONFAT 2 - LOW FAT 3 - HIGH FAT 4 - ENTIRE DAIRY/MILK GROUP Choose a number F1 HELP F10 EXIT --------------------------------------------------------------------- On selecting numbers 1 through 3, you will be presented with a screen of foods that represent a subset of the entire DAIRY/MILK group. If #1 was chosen, the screen might look like this: --------------------------------------------------------------------- NONFAT DAIRY/MILK GROUP FOOD DESCRIPTION FOOD NO. -------------------------------------- DN MILK/NONFAT/INST/DRY ### DN MILK/SKIM ### DN ... Display more (Y or N) ? --------------------------------------------------------------------- The DN found under the GROUP heading represents the Food Group DAIRY/MILK (D) and its subgroup NONFAT (N); therefore, the 2-letter food group code is DN, for NONFAT DAIRY/MILK. These food group codes are further described in the ADD A FOOD routine, and APPENDIX E. The ### is the symbol we have used to represent where you will find the FOOD NO. in the screen above. The listings for a particular subgroup or subset of a group will vary in their length. Notice the prompting question at the bottom of the screen. To display more of the NONFAT DAIRY/MILK subgroup, press Y for yes; if you do not want to see more of the subgroup being displayed, press N. This message then appears: _____________________________________________________________________ DISPLAY FOOD(s) -28- NUTRIENT FOOD(s) (cont'd) END OF GROUP Continue DISPLAY Routines (Y or N) ? This message will be seen when either the end of the subgroup or the entire group listing has been reached. Press Y to return to the DISPLAY SCREEN 3-option menu; press N to return to NUTRIENT's MENU. 4 - ENTIRE DAIRY/MILK GROUP Finally, if you choose #4 of the DISPLAY DAIRY/MILK screen, you will see a screen similar to the screens representing the subgroups. However, it will possibly be more than one screen of displays since it will be a listing of the ENTIRE group. Part of it will look like this: --------------------------------------------------------------------- ENTIRE DAIRY/MILK GROUP FOOD DESCRIPTION FOOD NO. ------------------------------------- D CHEESE/AMERICAN/PAST ### D CHEESE/BRICK ### D CHEESE/CAMEMBERT ### D .... Display more (Y or N) ? --------------------------------------------------------------------- The D represents the food group DAIRY/MILK; only one letter is used to represent the entire group. The "Display more (Y or N) ? " prompt is described with the NONFAT DAIRY/MILK screen above, as is the prompt: END OF GROUP Continue DISPLAY Routines (Y or N) ? The HELP and EXIT routines are available with the main DISPLAY SCREEN, DISPLAY FOOD(s) screen, and each FOOD GROUP screen. FOODFILE -------- 2 - FOODFILE Selecting the #2 option of DISPLAY SCREEN will produce this message: Please Wait ... Sorting Foodfile ... NUTRIENT is now alphabetically sorting the entire FOODFILE. The time to complete this task depends on your system and the current size of the database. For a database of 700 foods, my system using a RAM disk will do this sort in about 10 minutes. This is the longest WAIT you will encounter. This sort can be done in the PRINT routine also, to get a hardcopy. While sorting, NUTRIENT will give you a progress report: 1/4 done ... 1/2 done ... _____________________________________________________________________ DISPLAY FOODFILE -29- NUTRIENT FOODFILE (cont'd) etc.. Once done, here is a portion of the screens you will see: --------------------------------------------------------------------- DISPLAY FOODFILE NO. FOOD DESCRIPTION NO. FOOD DESCRIPTION NO. FOOD DESCRIPTION --------------------------------------------------------------------- 782 ABALONE/RAW 409 BABYFOOD/APPLESAUCE 966 BEAN/BLACK/DRY ### ... ### ... ### Continue sorting (Y or N) ? --------------------------------------------------------------------- Each screen will contain 60 foods sorted in ascending alphabetic order from the top of the screen to the bottom. To continue the sort (displaying screens), press Y; the foods will be cleared and replaced one by one until another 60 foods are displayed. The current 700 food database will require 12 display screens. To stop or exit these sorting screens, press N. You will then see the following message and prompt: END OF SORT Continue DISPLAY Routines (Y or N) ? The two above lines will also be seen at the normal finish of these sorting screens. Pressing Y will return you to the main DISPLAY SCREEN 3-option menu. Pressing N will exit you from the DISPLAY routines and present NUTRIENT's MENU. FOOD INTAKE ANALYSIS -------------------- 3 - FOOD INTAKE ANALYSIS Selecting #3 from the main DISPLAY SCREEN menu produces: --------------------------------------------------------------------- DISPLAY FOOD INTAKE ANALYSIS Please enter the following: NAME (First Last): --------------------------------------------------------------------- You have entered the DISPLAY routine's FOOD INTAKE ANALYSIS option. If NUTRIENT has already analyzed an individual's diet, that person's diet analysis can be displayed after making two entries. First, enter the individual's NAME as it was first entered for the FOOD INTAKE ANALYSIS. DATE (MM-DD-YY): Second, enter the DATE that was first entered for that individual's FOOD INTAKE ANALYSIS. Press ENTER after both entries. If the NAME or DATE are not correct, that is, if they have not been entered as first entered to produce the analysis, this message is displayed: FOOD MAN's file not found. Try Again. _____________________________________________________________________ DISPLAY FOOD INTAKE ANALYSIS -30- NUTRIENT FOOD INTAKE ANALYSIS (cont'd) FOOD MAN is used to represent the individual's name you would enter. The message will be erased, and another NAME & DATE can be entered. If the NAME & DATE combination are correct, the analysis will be displayed looking something like this: --------------------------------------------------------------------- DISPLAY FOOD INTAKE ANALYSIS FOOD MAN Height (in): 72 Frame: medium Intake Date: 03-01-86 Weight (lb): 165 Activity: light Age (yrs): 37 Sex: male WtRange: 157-170 --------------------------------------------------------------------- FD.ENERGY 20%|xxxxxxxxx PROTEIN 60%|xxxxxxxxxxxxxxxxxxxxxxx CALCIUM 5%|xx IRON 16%|xxxxxxx MAGNESIUM 12%|xxxxx PHOSPHORUS 58%|xxxxxxxxxxxxxxxxxxxxxx ZINC 0%| VIT.

E 0%| CHOLESTEROL 53%|xxxxxxxxxxxxxxxxxxx % RDA --- ^ -> ^100% ^300% Press SPACE BAR to continue --------------------------------------------------------------------- The phrase `something like this' is used because the personal data displayed will change depending on what population group the person falls into. For instance, for a child less than 19 years, height percentile and weight percentile will be displayed instead of simply height and weight. Other changes will be noticed for this group as well as other population groups. In essence, the personal data displayed will reflect the same categories of data that was entered during the Food Intake Analysis routine. The parts of the above screen will now be discussed. First, the heading, DISPLAY FOOD INTAKE ANALYSIS, which tells you that you are in the DISPLAY routine and the FOOD INTAKE ANALYSIS option. The next three lines display the individual's Personal Data that was first entered in the Food Intake Analysis routine. The height entry is worth mentioning since it may be 1 inch greater than the height entered in the initial Personal Data. The reason for this is because height was requested to be entered without shoes. However, NUTRIENT uses a reference for part of the adult population, ages 25 to 59, that uses height in shoes with one inch heels to determine weight range. Therefore, 72 in. represents height in one inch heels, and 157-170 is its respective weight range. The next major part is the graph of 17 nutrients. Immediately to the right of the nutrient's name is a percent. This percent is the average daily intake of that nutrient, calculated as a percentage of _____________________________________________________________________ DISPLAY FOOD INTAKE ANALYSIS -31- NUTRIENT FOOD INTAKE ANALYSIS (cont'd) its Recommended Dietary Allowance (RDA). To the right of the percent is a bar graph illustrated by X's which proportionately represents the percent value. The next major part is the line immediately below the graph: % RDA --- ^ -> ^100% ^300% The intention here is to point to the percent RDA as a number, and graphically. The first exponentiation symbol ^ points up to the percent RDA value (###%); the next two, point up to the place on the graph where 100 percent and 300 percent of the RDA would be. Press SPACE BAR to continue This is the prompt line of the DISPLAY FOOD INTAKE ANALYSIS screen. On pressing the SPACE BAR, the initial prompt is again displayed: Please enter the following: NAME (First Last): Enter another person's NAME to display another Food Intake Analysis. Or, to return to the DISPLAY SCREEN 3-option menu press the ENTER key. _____________________________________________________________________ DISPLAY FOOD INTAKE ANALYSIS -32- NUTRIENT ed: CHANGE A FOOD Enter Food Number to Change (0 to end)? As with the other main menu routines, the FOOD NO. is the key to receiving food and nutrient information from NUTRIENT. Simply
