Soy protein concentrate, produced by alcohol extraction vs Soy protein isolate, potassium type

Soy protein concentrate, produced by alcohol extraction, and soy protein isolate, potassium type, both score 89 of 100, with calories close at 328 and 321 per 100 g. The isolate has considerably more protein, 88.3 g versus 63.6 g, and far less carbohydrate and sugar, 2.59 g and 0 g against 25.4 g and 20 g for the concentrate. The concentrate, in turn, provides 5.5 g of fiber where the isolate has none, and carries much less sodium, 3 mg versus 50 mg.

Choose the soy protein isolate when protein density with minimal sugar is the goal. Choose the concentrate when fiber and lower sodium matter more than squeezing out extra protein. Both are highly processed protein sources, so the choice depends entirely on which secondary nutrient you are optimizing.
