Schenck says some of the negative effects seen with the consumption of over-processed soy products include:
Damage to the thyroid caused by goitrogens in soy products
Lectins in soy cause red blood cells to clump together and may damage immune system reactions.
The sugars in soy, oligosaccharides, cause bloating and flatulence.
Protease inhibitors, such as trypsin inhibitors, interfere with digestive enzymes and lead to gastric distress, poor digestion, gas, bloating, diarrhea, and an overworked pancreas.
The heating of soy during processing creates heterocyclicamines (HCAs), toxic carcinogenic byproductsalso found in cooked meat. These can lead to liver, lung, and stomach tumors, as well as lymphoma and leukemia.
The chemical process that breaks down the soybean’s protein structure into free amino acids also releases the excitotoxins glutamate (MSG) and aspartate.
