Could soy flour be added to water or milk to make a dietary supplement health drink?
There are a number of soy products already on the market that provide sufficient soy for health benefits. These include some powders (usually soy protein isolates) that can be scooped from the package, as well as ready prepared soy shakes. Soy flour has a very distinctive taste that is difficult to mask, and is not very dispersible or soluble in water or milk (in comparison to protein supplements). That is why there is no product already on the market that is essentially soy flour plus sugar and flavor.
