These do not contain equivalent amounts of protein or bioactive ingredients. In referring to research studies, it is critical to quote what type of intervention was used. The study quoted above in Am J Clin Nutr by Alekel et al. (2010) used isoflavones extracted from soy protein, which is a very different intervention than soy protein or soy foods. Scientists do not necessarily know for certain which "ingredients" from soybeans are most critical for a given biological effect. Soybeans contain thousands of compounds, making it difficult to pinpoint which bioactive component exerts its effect on which particular tissue. Very complex!

Another study cited in this website referred to how the anti-inflammatory effects of soy could only be found in soy flour, and then only from soy beans grown in optimal conditions.
