Okay, so I've read a lot of the research about why soy is bad, and while I'm somewhat convinced, I still don't think anyone has properly addressed the "Asian argument", ie the fact that a lot of traditional Asian diets contain a lot of soy.
For example: http://paleodietlifestyle.com/dangers-soy/
Argument 1: "Asians mostly eat fermented soy which is okay."
Well, no, Asians also eat a lot of tofu, and drink soy milk on a regular basis. In China, soy milk is considered to be a traditional morning beverage.
Argument 2: "When they eat soy, they have it with mineral rich fish broth, which makes it okay"
Really? That sounds like such an ad-hoc argument. Again, that is just not the case. Tofu is used in a variety of dishes, including stir-frys, stews, and even desserts. Also, there's the soy milk again..
I'm not saying that soy is good, but can we not say that the research is still far from conclusive? FWIW I'm Chinese and grew up eating mostly traditional Chinese food.
