Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 675 of 1385 records have some flagged component, while the rest do not. Compare 100% All Natural Chicken Breast Mini Nuggets Patty Fritters With Rib Meat, Chicken Breast; 48 Oz; 5 Yogurt & Oat Bar to see how surrounding formulations change; do not assign their 0–100 score range to Isolated soy protein itself. The ingredient most often sits in the upper half of the list, and Frozen foods supplies the most useful like-for-like starting point for a label review.
675 of 1,385 linked records have some flagged component
All 1379 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.
What else is usually in the same product as Isolated soy protein
Across the 1,385 products on this site that list Isolated soy protein, these flagged additives appear alongside it most often.
