Unfortunately, even in the case of vegan milk substitutes, such as soy milk and its derivatives, genetically modified (GM) glyphosate-tolerant soy beans (GT), which dominate the soy bean market throughout the world, introduce thousands of tons of herbicides into the food chain [327] and bioaccumulate glyphosate (GLY), as well as its major degradation product aminomethylphosphonic acid (AMPA), which may itself act as an endocrine disruptor, mimicking 17β-estradiol that promotes ERα activity in BC cells [328]. The gene discussed is ESR1; the disease is breast cancer.
