Soy Protein Isolate

Soy protein isolate is an ultra-processed extract with poor nutritional value relative to whole food protein sources. Soy protein isolate is extracted from soybeans using hexane, a petroleum-derived industrial solvent. There is no regulated monitoring standard for the amount of residual hexane remaining in soy protein isolate after extraction. Soy protein isolate is a highly processed protein source nearly always derived from GMO soybeans. Soy protein isolate is widely present in protein bars, meal replacement shakes, plant-based meats, and packaged snacks.
