01
A score is a summary, not the whole answer
JFS combines available nutrition and ingredient signals into one educational product rating. The product page keeps the supporting factors visible so the number is never the only information you see.
JFS basics
What does a JFS score actually mean?
The score is a compact summary of available product data under JFS rules. It is useful only when you can also inspect the factors, source, and limitations behind it.
02
The score depends on source quality
A product can only receive a full JFS rating when the required nutrition and ingredient information is available and passes basic plausibility checks. Missing or conflicting records should not be presented with false certainty.
03
A higher score is a limited comparison
A higher JFS score means the product performed better under the current JFS scoring rules using the available data. It does not guarantee that the product is healthy, safe, suitable, available, or appropriate for a particular person.
04
Scores can change
Product formulations, package sizes, source records, and JFS methodology can change. A score is tied to the data and scoring version available at the time it is calculated.
Remember: JFS is for general education. Always verify the current package label, and use professional guidance when you need individualized health, dietary, or allergen advice.
