Organic shows healthiest nutritional profile in soybeans: GM soybeans have high pesticide residues

A recent article published in the journal Food Chemistry found that organic soybeans have a healthier nutritional profile than conventionally grown soybeans.  The study compared organic soybean batches from Iowa with genetically modified (GM) soybeans and conventional non-GM soybeans grown in the same state.  They found that “organic soybeans showed the healthiest nutritional profile with more sugars, such as glucose, fructose, sucrose and maltose.”  Organic soybeans also had more total protein and zinc, and contained less total saturated fat and total omega-6 fatty acids than both conventional and GM-soy.  Another interesting find of the study was that GM soybeans contained high residues of pesticides, showing 3.3mg/kg of glyphosate and 5.7 mg/kg of AMPA.  These contaminants were not found in non-GM soybeans, and support previous research suggesting that the use of GM crops enables higher use rates of some pesticides.

    I am curious to the difference in levels of isoflavones between the two type of plants.
