Fatty acids are the additives the food industry lists as E570. In our table they are no risk identified: they take no points off a product's score.
- The key finding, from EFSA: No safety concern at the reported uses and use levels (EFSA re-evaluation of fatty acids (E 570) and of sodium/potassium/calcium salts of fatty acids (E 470a) and magnesium salts of fatty acids (E 470b), EFSA Journal 2018;16(3):5180, doi:10.2903/j.efsa.2018.5180)
- No child flag. The class, and the points it costs, are the same for a child of any age.
- Where you meet it. They turn up in 14 of the 10,000 packaged foods scanned most on Open Food Facts, most often in margarines and crackers. Nine in ten of those foods are sold in Europe (counted 26 Sep 2026).

What Fatty acids do to a score
A packaged food's additive subscore starts at 100 and loses points for each additive on the label; that subscore is a third of the final score. Fatty acids take no points off a product's score. Scan the pack in Sito and the score you get is the one for your own child's age, with this additive named in the reasons. How we score has the whole method.
See what is in your own cupboard
Scan a packaged food and Sito names the additives in it, then scores the product out of 100 for your child's age.

re-evaluation of fatty acids (E 570) and of sodium/potassium/calcium salts of fatty acids (E 470a) and magnesium salts of fatty acids (E 470b) — EFSA Journal 2018;16(3):5180, doi:10.2903/j.efsa.2018.5180
No safety concern at the reported uses and use levels.
Why this class
Clean current EFSA and FDA status. These rows exist so that an unfamiliar additive is never treated as a bad one: a missing row costs a product nothing, and a clean row says so with citations.
Our confidence in this row's classification is high. Medium or low does not mean the evidence is weak; it means something about the row is still being pinned down, usually a regulatory status confirmed from one source rather than two.
Questions parents ask
Are Fatty acids (E570) safe for kids?
No risk identified. No regulator finding we score, so a product keeps its full additive subscore in Sito. The current status is clean: No safety concern at the reported uses and use levels (EFSA re-evaluation of fatty acids (E 570) and of sodium/potassium/calcium salts of fatty acids (E 470a) and magnesium salts of fatty acids (E 470b), EFSA Journal 2018;16(3):5180, doi:10.2903/j.efsa.2018.5180).
What is E570?
E570 is the E number for Fatty acids, which our table lists as an additive. Open Food Facts tags it en:e570.
