One of the reasons I discourage GMO soy, more research coming out shows GMO soy retains toxic glyphosate (RoundUp herbicide) residues. The health benefits are actually not as good as organic soy or conventional non-GMO soy.
I am also questioning the benefits of soy in general. If you are gluten sensitive or celiac, it may be a good idea to avoid ALL soy for a while. I know this is hard to do because GMO soy is in EVERYTHING and used mostly in processed foods and fast food. Consider avoiding fast food and restaurant foods while trying to get symptoms under control. This means cooking from scratch and reading ingredient lists.

This article describes the nutrient and elemental composition, including residues of herbicides and pesticides, of 31 soybean batches from Iowa, USA. The soy samples were grouped into three different categories: (i) genetically modified, glyphosate-tolerant soy (GM-soy); (ii) unmodified soy cultivated using a conventional "chemical" cultivation regime; and (iii) unmodified soy cultivated using an organic cultivation regime. Organic soybeans showed the healthiest nutritional profile with more sugars, such as glucose, fructose, sucrose and maltose, significantly more total protein, zinc and less fibre than both conventional and GM-soy. Organic soybeans also contained less total saturated fat and total omega-6 fatty acids than both conventional and GM-soy. GM-soy contained high residues of glyphosate and AMPA (mean 3.3 and 5.7 mg/kg, respectively). Conventional and organic soybean batches contained none of these agrochemicals. Using 35 different nutritional and elemental variables to characterise each soy sample, we were able to discriminate GM, conventional and organic soybeans without exception, demonstrating "substantial non-equivalence" in compositional characteristics for 'ready-to-market' soybeans.
