Guest guest Posted April 2, 2006 Report Share Posted April 2, 2006 The problem with the USDA database's is that often a value is not entered for a specific nutrient. Computers cannot deal with NO DATA, so one must enter a zero, somehow. That in a sense is an "error". If you have a tool where a value is omitted, you might find it in another source like Duke's database. When I made my spreadsheet, I had to enter literally thousands of zeros. Also, there are additional USDA Tables like flavonoids. isoflavones, et al. These are sometimes cumbersome to add, and not added to commercial tools, I think. What may be of value is to add all the values and items to the USDA, but probably no one will ever do that outside the government. Maybe 2035. You can d/l your own SR18 and a tool at: http://www.nal.usda.gov/fnic/foodcomp/Data/ ALSO: USDA National Fluoride Database of Selected Beverages and Foods - 2004 USDA Database for the Proanthocyanidin Content of Selected Foods USDA Database for the Choline Content of Common Foods - 2004 USDA Database for the Flavonoid Content of Selected Foods - 2003 USDA Table of Nutrient Retention Factors, Release 5 (2003) USDA - Iowa State University Database on the Isoflavone Content of Foods - Release 1.3, 2002 Keyfoods Key Foods are identified as those foods contributing up to 75% of any one nutrient. Oxalic Acid Content of Selected Vegetables If you like and have the time for daunting tasks, d/l the SR18 into MSACCESS, and copy the crosstab query to Excel. Then "adapt" it to daily usage. Regards. [ ] Re: Fitday? Hi Iunipera:I bet you eat kale! For a long time the USDA database, which all nutrition software uses to generate its output, showed kale to have zero vitamin K (perhaps other foods too?). But any other source would tell you it is a huge source of it. My GUESS is that finally the USDA has corrected its database entry for vitamin K in kale.But there were other difficulties with Fitday that I had noticed, and told them about, which could not have been the fault of the USDA. Perhaps they have fixed them too.Best way to check is to go through the vitamin K content of your diet item by item using a different source, and see if the total matches up with what Fitday claims it to be. And similarly for other nutrients if they look suspiciously high or low.Rodney.>> I've been using Fitday for several months but in the past week (since> their new skin) the numbers seem very off.
