Soy flour, low-fat vs Soy protein isolate, potassium type
Original comparison by NutriVerdict
Bottom line: Soy protein isolate, potassium type is the more nutrient-dense of the two, scoring 89 of 100 to 88 for Soy flour, low-fat.
Soy protein isolate edges out soy flour on nutrient density, 89 of 100 versus 88 of 100, but the two foods serve different purposes. The isolate delivers 88.3 g protein per 100 g against 49.8 g in the flour, while the flour supplies 30.6 g carbs and 16 g fiber, compared to just 2.59 g carbs and 0 g fiber in the isolate. Sodium is 50 mg in the isolate versus 9 mg in the flour.
Pick the isolate for maximum protein with minimal carbs, ideal in protein-forward recipes. Pick soy flour when fiber is the goal, since 16 g per 100 g is substantial and the isolate offers none. Both scores sit close together, and even the isolate's higher sodium remains modest in absolute terms.
