Champion 13323 | Subject: Nutrition Log FAQ THIS NURITON SOFTWARE IS BETA! Always exercise caution in any interpretation. There WILL be bugs in this software for a week or so. PLEASE check our math in the totals and reports/graphs for main nutrient items that have values associated with them. Several things simply WILL NOT add up, details at the end. Also these foods will not ‘exactly’ match what’s on a real nutrition label due to rounding, lots, manufacturer, year, etc. But they are reasonably close based on the foods we tested from our fridges and pantry. You will also note that these numbers will not exactly line-up with other nutrition dbases due to different dbase version, sources, and the aforementioned issues.
*I will try to get real instructions in an article format with pictures and how-to's out in a few weeks. Free users:

All the following is directly from the USDA dbase FAQ. About the Dbase. The USDA National Nutrient Database for Standard Reference (SR) is the major source of food composition data in the The dbase we are using has the 7,146 foods. NOT ALL of them have complete nutrient profiles. ‘N/A’ is seen when this value is not reported. For BT logs in daily, weekly, monthly and yearly summed reports, ‘N/A’ is treated as a ‘0’ so everything most likely will not add-up perfectly (example, individual amino acids adding up to the amount of protein….some foods lack the amino acid compositional breakdown.) Carbohydrate Calculation Assumptions Fat Calculations Assumptions Values for total saturated, monounsaturated, and polyunsaturated fatty acids may include individual fatty acids not reported; therefore, the sum of their values may exceed the sum of the individual fatty acids. In rare cases, the sum of the individual fatty acids may exceed the sum of the values given for the total saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA). These differences are generally caused by rounding and may be relatively small. Zero values for individual fatty acids should be understood to mean that trace amounts may be present. When g fatty acids per 100 g of total lipid were converted to g fatty acids per 100 g of food, values of less than 0.0005 were rounded to 0. Protein Calculations and Assumptions MANY THANKS TO marmadaddy...he tested many of the features, caught several bugs and found many things we never even thought of. |
