Ingredient
Soy Protein Isolate
Scout's take
Soy protein isolate is a heavily processed protein extracted from soybeans using chemical solvents like hexane. The majority of soy in the US is genetically modified. It contains phytoestrogens that may disrupt hormonal balance and is used as a cheap filler protein inferior to whey in bioavailability.
The case against
Typically GMO-derived. Extracted using chemical solvents. Contains phytoestrogens that may affect hormone levels. Inferior bioavailability compared to whey.

from the analysis of Clif Bar Chocolate ChipHighly processed isolated soy protein. Animal proteins offer a more complete, bioavailable amino acid profile, so Scout classifies soy protein isolate/concentrate as bad.
