The composition of foods is expressed per 100 g of the edible part (i.e. meat without bones, vegetables without waste, canned foods without brine of sweetened liquid).

This also accounts for foods such as oil and ice cream, which have a density different from water. Label information for these foods is often presented per 100 ml. Users should be aware of this difference when comparing label information with NEVO online data.

In certain cases, the composition of prepared infant formula and liquid foods for specific dietary use may be displayed per 100 ml, if the manufacturer has provided such data. When the food composition is not per 100 g of food, this is indicated in the food name.


Nutrient content is expressed in units used by the Dutch Health Council’s Committee on Dietary Reference Values for recommended daily intake. For macronutrients, the unit is gram (g) whilst for vitamins and minerals it is milligram (mg) or microgram (mcg). 

Variability of data

Information in NEVO should be viewed as the closest approximation of actual values. Foods are subject to variations in composition for various reasons. Natural variation among comparable foods may arise from differences in breed or variety, cultivation or breeding method, soil conditions, season, harvest time, and storage conditions.
Differences in composition may also in production although these processes are subject to stringent quality requirements. The use of different ingredients and methods of preparation,  in the industry or at home, is another potential source of variation.
