The reason I think soy sways pink is because soy lowers testosterone (there is conflicting info on this as well BTW). IG thinks soy sways blue because it has these things called "phytoestrogens" in it which are similar chemically to our body's estrogen (and IG says estrogen sways blue, which may or may not be true.) But, the issue with phytoestrogen is that it is NOT the same as actual estrogen, one study showed that phytoestrogens are only 1/10,000 as effective as real estrogen, and it can actually interfere with your body's production and use of real estrogen by competing with real estrogen for estrogen receptors and also "tricking" your body into relaxing production of estrogen because it thinks it has enough. So it may be that soy can both lower testoterone and effectively lower estrogen, which would then free up more raw materials to make progesterone (which may sway pink or be totally neutral).
The interplay of testosterone, estrogen, and progesterone is SO unbelievably complicated that not even the smartest researcher on the planet has much of a clue about how it all works. So when I say I believe soy iso sway pink, this is just my best guess based on the best info that I can get my mitts on.
If you do take soy iso, I would take an antihistamine just in case it makes more CM for you.
