Frequently asked questions
Stated below are the most frequently asked questions. If your question is not on this list you can always contact us on email@example.com.
Yes. In NEVO all information on the source is kept, which means it is always possible to retrieve the origin of the data. NEVO online provides this information behind each nutrient in the part ‘product details’. You can see this by clicking on the food name.
No. Analyzing foods is very expensive. RIVM tries to keep the nutritional information of foods up-to-date by using analytical results from other organisations, research institutes and universities, data from foreign food composition tables, information form manufacturers (NethFIR) and calculations and recipes.
No. Unfortunately it is impossible to check all values (and correct them if applicable) for each new version of NEVO-online.
Yes, if you need previous versions of NEVO-online for your research you can send a request to firstname.lastname@example.org, but not all versions are still available and the format can be different. Using former tables needs attention to some aspects. The nutritional value of products can change over time. Values can be replaced by newer analyses; this can result in some differences in nutritional value although the product itself did not change.
In December 2021 the most recent version of NEVO online is released: NEVO online version 2021/7.0. When the next version will be released is unknown.
In NEVO total carbohydrate is given excluding dietary fibre. The amount of dietary fibre is given separately.
Yes, since NEVO online 2021 polyols are included in the avalaible carbohydrates. The amounts of carbohydrates in products with polyols are higher than in previous versions of NEVO online.
No, recent information on values of the mono- and disacharides is not available. In NEVO online the total of mono- and disacharides is shown. There is no distinction between sugars added and/or natural in the product.
Because, in addition to fatty acids, fats also contain other compounds such as glycerol, sterols and phospholipids. Food items with a relatively high amount of these compounds, i.e. egg and offal, contain relatively less fatty acids. The value for total fatty acids is between 80-96% of total fat.
Because actual information on the types and amounts of fats and oils in margarin products, fats for frying and deep frying is missing, it is not possible to calculate the seperate fatty acids. Also, no recent analyses for fatty acids are available for these products. Therfor the seperate fatty acids are not published. If recipes contain these fat products as an ingredient, the fatty acid composition is also not published (e.g. cakes).
The fatty acids are presented in a different way. In previous versions percentages of the total amount of fatty acids were shown. In NEVO-online 2019 the values are absolute values (g/100 g food). In this way you can easily calculate the amount of fatty acids in a recipe or a diet. Also, now it is better visible that foods with a low amount of fat contain little fatty acids.
Salt as such is not mentioned in NEVO online, but sodium is. 1 gram of salt (NaCl) contains 400 mg sodium. You can calculate from sodium to salt. In NEVO online sodium is the combination of sodium from natural source and from added salt.
This is probably a translation issue in The Netherlands: ('foliumzuur'): folic acid is synthetic , added to foods, and folate is natural.
No. In the Netherlands there are companies developing nutrient calculation programs in which NEVO data is implemented. When buying such a calculation program it is important to check if recent NEVO data is used, preferably data from NEVO online 2021.
Foods for clinical nutrition, such as tube feeding, are not present in NEVO online. For users the nutritional values should be up to date at any time, and this is not possible for us to present this i n NEVO online, because of the frequently changes in assortment and composition.
Yes, they are changed because of the new softwaresysteem for NEVO. The codes are different. For each value, a reference is known. You can see these for each food in the Product details screen, which you enter by clicking on the food name in NEVO-online. A translation table from 2019 to 2016 is available on the website.
Macronutrients protein, carbohydrates, fat and water are available for almost all foods in NEVO online. The seperate fatty acids, fibre, minerals and vitamins are sometimes missing. See for more information the document Coverage rate components.
Which reference can I use to refere to NEVO online?
The reference to be used is: NEVO online version 2021/7.0, RIVM, Bilthoven
You can send an e-mail to email@example.com with the reason why you want to see this nutrient in NEVO online. Thus we can see the nutrients missed by our users and the urgency of it. We will keep this in mind while prioritizing our work.
Foods in recipes are coded prepared as much as possible, in order to represent the loss of water, minerals and vitamins during preparation. In order to give the best fatty acids composition raw meat is coded, because fried meat in NEVO contains cooking fat.
