Our nutrition team compiles nutrition data from different sources and provides that to our customers.  For example, if you wish to know how we calculate Trans Fatty Acid data for the foods.  Please note we compile data from many sources like USDA or Europe or Direct from manufacturer.  We then input that data into our application and our database sources provide that to us.   The USDA or Europe or Manufacturers calculate their nutrient values based on the industry standards that are allowed for them.
