Soy Protein Isolate
Soy Protein Isolate appears in 3,949 indexed US food products. No FDA SAFFA status or CSPI rating is attached in this snapshot, so this page reports prevalence rather than a safety verdict.
What the data can answer

This page therefore cannot answer whether the ingredient is safe from those sources. It can show how often it occurs, where it tends to sit on labels, and which kinds of products contain it.

Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 1612 of 3949 records have some flagged component, while the rest do not. Compare 100% Natural Fruit And Nutty Layered Granola Bar; 12 Protein Bars Variety Pack; 12 Soft Kaiser Rolls Enriced to see how surrounding formulations change; do not assign their 0–100 score range to Soy Protein Isolate itself. The ingredient most often sits in the upper half of the list, and Snacks supplies the most useful like-for-like starting point for a label review.
1612 of 3,949 linked records have some flagged component
All 3937 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.
