How to use this page
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 3140 of 8182 records have some flagged component, while the rest do not. Compare 0016500579793; 1% Chocolate Lowfat Milk; 1-2-3 gluten free, southern glory, biscuits baking mix to see how surrounding formulations change; do not assign their 0–100 score range to Calcium Carbonate itself. The ingredient most often sits in the lower half of the list, so it is typically a smaller component by weight, and Snacks supplies the most useful like-for-like starting point for a label review.
All 8095 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.
