Nutrients
Our nutrient library holds 32 pages: thirteen vitamins, thirteen minerals and six other nutrients. Each page shows which foods hold the most according to our database, with the content per 100 grams, and the daily reference intake attached to it. We always name the source of that reference value in full.
Three groups, and what sits in the third
The first two groups are the vitamins and the minerals, with thirteen pages each. The third is not a category but a remainder of six nutrients that were given no hub of their own for practical reasons: choline, fibre, omega-3, caffeine, leucine and the essential amino acids. A hub with two or three children is an empty page with a menu, so those six appear here as a section. Chromium, fluoride and sulphur have no page at all, for a simple reason: those columns do not exist in our nutrition database, and a page about where chromium is found with not one food beneath it is an empty page.
What a reference intake is and is not
Every nutrient carries a daily reference value with its source: EU NRV, EFSA PRI or EFSA AI. Those three are not the same thing. An EU NRV is the labelling value from European regulation, meant to make products comparable. An EFSA PRI is an estimated requirement for almost the entire population. An EFSA AI is an adequate intake, used where the data for a PRI are missing. So we always state which one it is, rather than sweeping everything under the heading recommended daily allowance. What we do not do is turn it into advice. A reference value is a number for a population, not a prescription for your week, and it says nothing about whether your own intake is low. If you suspect a deficiency, have your doctor establish it.
Why there are no symptom lists here
These pages carry no lists of complaints that might indicate a deficiency, and no supplement recommendations. Two reasons. One is legal: what may be written about the effect of a nutrient is limited to the literally permitted wordings in Regulation (EU) No 432/2012, and those appear here verbatim, in quotation marks, with the regulation named. The other is substantive: a symptom fits dozens of causes, and a list online is the worst possible tool for choosing between them.
Frequently asked questions
How many nutrients are in the library?
32 pages: thirteen vitamins, thirteen minerals and six other nutrients. Chromium, fluoride and sulphur are missing because those columns are not in our nutrition database.
Where do the reference intakes come from?
From our database, which records per nutrient whether the value is an EU NRV, an EFSA PRI or an EFSA AI. That label appears verbatim on every nutrient page.
Can I work out from this whether I need a supplement?
No. These pages describe where a nutrient is found and which reference value applies. Whether you are short of something is established by your doctor with a measurement, not by a table.
