For diets in which protein offers about 15 % of energy, the resulting error for complete dietary vitality is small, at about 1 %. In the case of fats, the Atwater general issue of 37 kJ/g (9.zero kcal/g) is usually used.

Energy values in centrally maintained databases are prone to be modifiable, some with less effort and cost than others. Depending on the supply and high quality of the analytical information, standardizing on a single set of ME components is likely to be no simpler than adopting NME elements. Neither modification may be attainable, depending on the source of the analytical data. The main database may be modified by altering components in an algorithm within the system and utilizing the new components to recalculate the database. Thus, altering power conversion elements within the main database is comparatively straightforward from a purely mechanical point of view, and it need not be problematic for a database to hold and disseminate quite lots of energy values for food. The ease or issue of that task will rely upon how the secondary database was constructed.
