| Auron 12-30-2002 07:58 PM | I am not for sure how to use it and what it means when it say missing item and a number and why are there 2 raw egg yolks? |
| Wai 01-02-2003 02:48 PM | quote:Submit a complete one day diet to it: for every food the consumed amount. Then it will calculate the total for each nutrient, and compare it to official RDAs. quote:A missing item means that for that nutrient the contents of one or more foods was unknown. the reason: Not for all foods all nutrient contents are known. And the unknown ones appear as 'missing items' in the nutrient calculator, so that you know that the actual total for that nutrient is higher than reported. The number stands for the food in which that contents of that that specific nutrient is unknown; e.g. if, regarding selenium contents, it says: "missing items 3, 4", it means that for the foods number 3 and 4 the selenium contents are unknown. quote:Because we have used different sources. Different scientific studies supply us with different results. In general these differences are only small, but sometimes they are a bit bigger. "Chicken Egg yolk (Gallus domesticus), raw, (1)", means that here the European and Japanese findings from Souci, S.W. et al, Food composition and Nutrition Tabels, Medpharm Scientific Publishers Stuttgart are used. "Chicken Egg yolk (Gallus domesticus), raw, (2)", means that here the findings from the USDA are used. |
| Auron 01-02-2003 11:20 PM | how do I know I am deficient then do I just compare to the RDA because I would be deficient in calcium,iron,protein and some say missing items and what does this (FAO/WHO 85) mean? |
| Wai 01-06-2003 03:08 PM | quote:No, the RDAs are safe levels. With those levels, nobody will be deficient, regarddless of the absorption rates. In practise, you need much less, because the body does adjust the absorption rate to the availability of each nutrient. vitamin RDAs are more accurate than mineral RDAs because the absorption rates for minerals vary to a greater extend. very roughly, 50% of mineral RDAs is already sufficient. Actual vitamin requirements are closer to the RDAs. quote:protein? ; Are you not eating any egg yolks, fish or Brazil nuts? regarding calcium and iron: what foods did you submit, and in what quantities exactly? How much (%) of the iron RDA is covered? The actual calcium requirements are between 300 and 400 mg daily, see http://www.4.waisays.com quote:i already explained what that means... (see my previous post in this thread) quote:that the data are obtained from the joint FAO & WHO report in 1985. |
| Auron 01-06-2003 06:01 PM | well I would not be deficient in calcium if it was 300 I was comparing to rda requirements according to rda I would be deficient in calcium,iron,protein I did have both eggs(2 a day to get used to it along with some brazil nuts no fish though.) |
| Wai 01-07-2003 03:15 PM | Exactly what foods did you submit, and in what quantities? Were your energy requirements met? |
| gavriel 05-08-2003 07:56 AM | I want to know the norm (standart necessary amount) of a certain nutrient to make sure I have enough of it. I chose "Man, 25-30...."etc. and submit my ingridients. I see the values for the amount of each ingridient in my diet... but... Where do I see the required amounts recommended by the FDA (for example) for each nutrient? ![[Cool]](../cool.gif) |
| Wai 05-08-2003 08:06 AM | quote:on top of that list of nutrients, first are listed: RDA: xxx (your age group and RDA source, selected by you) selection: xxx (the fruits that you selected) weight: xxx (total weight of the selected foods) and then it subsequently lists: Constituents....Quantity.....RDA and below the header "RDA" you find the recommended amount (recommended by the FDA or JSNFS) per nutrient... (if given at all by the FDA or JSNFS) |
| gavriel 05-08-2003 08:33 AM | O.K. this is clear now. 2 more questions abou thte calculator: 1) What does "RDA" stands for? 2) some values have for example ".........?mg" after them and some ".............?mg missing items:1, 12, etc." what is the difference? Gavi. |
| gavriel 05-08-2003 08:48 AM | Please dissregard question no. 2) above. I did not notice it was unswered already. Nevertheless, I don't really understand yet the 'missing item' issue; If a certain food is being studied/examed and at the end of the day say 30mg of it are "unknown" = can not be identified (correct?) how can these 30mg then be associated with a specific nutrient? If they could associate those 30mg with this nutrient, then it would be "known", wouldn't it? ??? g. |
| Wai 05-10-2003 02:25 PM | RDA = recommended daily amount (based on an estimated multiplications of minimally required doses, and given the assumption that more is generally better) quote:no, the 30 mg is from sources of which we DO know how much it contains of that nutrient X. Missing items 11 en 12 means that we dont know how much X they contain, so that 30 mg is the result of the total of X in item 1 to 10. if 11 and 12 in fact contain some X too, in reality, the amount will be more than 30 mg in other words: 30 mg is for sure, but maybe its more is that clear now? |
| lizzie 05-18-2003 01:22 PM | hi I'm new to this, i stumbled upon this site a week ago, and after extensive research, this seemed like the best diet. i'm not trying to lose weight, and fortunately don't have an acne issue, just want to be really healthy, but i just want to get something straight, bc the nutrient calculator messes me up..when i enter the sample diet in there, it still has ie. missing items 1,2,3,4,5,6,7...and so on, like what? so is the sample diet missing nutrients? i'm confused. I know it says here that before u ask questions read the whole site first incase other people have asked that question but there is so much on here, that i have been reading and reading non stop and i would really just like to get started with this diet and have a couple things cleared up. So first is, what is up with the calculator confusion, and second, i wanna make sure i'm getting this right, every day, i eat a few raw egg yolks, some tuna, any one of the the combinations of fruit ie. orange-pineapple-watermelon, an avacado, handful brazil nuts and raisins and a cucumber/tomato salad, oh and a banana, and i'm getting all the vitamins and nutrients i possibly need daily? can kids grow off this? i mean this sounds incredible, and i wish more people would pick up on it, but i guess almost in a tiny way i'm a bit skeptical bc it sounds so good! And if i hadn't been cruising the internet looking up info on diets and never stumbled on this, i would never hear of this as well as many people i'm sure. Well anyhow, if I could get some feed back please it would be greatly appreciated. This sounds great, and thank you to wai and anyone who has helped you for doing such extensive research and putting this up for free, it is a great thing when people can do that for other people, what a better world it would be if everyone really cared about the good of other people |
| Wai 05-18-2003 01:32 PM | quote:no please read this thread; it is explained here... quote:i hope you mean raw tuna, right? you will get all the vitamins and minerals you need by eating this way, yes, but only if it also supplies you with sufficient energy... so, you are not allowed to undereat, because then you not only lack energy, but may also lack other nutrients (not due to the diet, but due to the undereating) kids can perfectly grow on this... |
| jhonyl 05-18-2003 03:36 PM | The calculator has a bug. When I want to choose tomatoes I have to choose salomon. Only then it say that I chose tomatoes. I couldn't find an item that I can choose to make it think that I chose Walnuts. I also think that the calculations are wrong, I computed myself the protein content of some of my diet and the numbers given by the calculator were much less than my calculations. So one of us had a computation error, I hope it was me. Please check it out. Do a verification and debuging of this software. |
| Schmolch 05-18-2003 06:29 PM | jhonyl, if it would be a bug in the nutrient calculator code it would affect all, or at least much more people. But as far as i can see its only 1, you. I have used the Calculator (and the tomato) many times without a problem and so have many others. If you are not even able to select the right foods that sounds more like your webbrowser is not very good in doing its job. Maybe you can update or upgrade it or switch to a better one. 2.) you think the calculations are wrong but you are not sure because you cant remember if your own calculations were right? Why dont you verify your suspicions with some more tests before you order Wai to do it for you? Well i can tell you that i made a small version of the Nutrient Calculator for my calculator (those you use in school/college, just a little bigger, sorry for my bad english) and of course i ran some tests if it calculated right and all the results matched. . THIS THREAD CONTAINS MORE THAN ONE PAGE; |
| lizzie 05-18-2003 11:11 PM | Thank you for the response, and i apologize if I seemed demanding about getting a response, I didn't mean to be! Anyhow, you have cleared up for me what I needed so again thank you! And I will make sure to read thru the threads so I don't repeat questions. |
| Sanna 05-19-2003 05:31 AM | jhonyl, I have the same problem with the nutrient calculator. If I chose oj I get olive oil...and egg yolks then I get muskmelon or something...I didn't have this before. Only very recently. Weird. |
| jhonyl 05-19-2003 06:36 AM | I use the following browsers: IE 6, Mozilla 1.3 under windows XP. Both have the bug. Here is what I get when I select only 100 gram Tomatoes: " RDA: FDA Children, 0.0-0.5YR, 6kg, 13lb, 60cm, 24in Selection: [Item-1] 100g (grams) of Salmon (Salmo salar), Atlantic wild, [1][2]," About your comment over verification: Every software have to be verified, so please don't take it so personally. Best verification is with automatic tests. Automatic tests can verify all in a short time, and without an effort. If your selected items turns out fine ... good for you. |
| RRM 05-22-2003 06:18 AM | Me and Wai don't know the first thing about the technical functioning of the calculator, so we'll ask the one who build the calculator for help. |
| aacesta 05-22-2003 03:25 PM | Hi it is Andre, who writes the calculator. I've sent Wai the last previous working version of the calculator, so she can roll the live one back to this working version. I'll investigate the problems you've found (indeed the last calculator had a bug). As for automated testing. Yes I can write some automated testing for it. I'll do that during the next release. |
| Wai 05-23-2003 10:53 AM | thank you dear Andre!!! ![[Smile]](../smile.gif) |
