How to use this page
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 1929 of 3950 records have some flagged component, while the rest do not. Compare 10 Flour Tortillas; 100% blueberry pomegranate flavored juice drink with 2 other juices from concentrate, blueberry pomegranate; 100% cranberry raspberry flavored juice blend, cranberry raspberry to see how surrounding formulations change; do not assign their 0–100 score range to Fumaric Acid itself. The ingredient most often sits in the lower half of the list, and Snacks supplies the most useful like-for-like starting point for a label review.
1929 of 3,950 linked records have some flagged component
All 3932 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 0–100 score spread more informative than the average alone: investigate the low end, identify the actual flagged row, and compare it with a similar unflagged formulation before drawing a conclusion.
Next check: pair one flagged product with a similar unflagged product from the same shelf category.
