My husband and I started to make smoothies about 2 weeks ago every day, adding soy/green protein powder to the fruit smoothie. Well, this month I had the worst PMS symptoms ever! My breast size increased by one cup size (at least), I was terribly bloated and the bottom left side of my left breast had a constant shooting pain. As the symptoms got worse as my period approached, I realized the soy powder was probably causing the side effects. I continued to have my daily smoothies, but stopped substituted rice protein in place of the soy powder. 2 days later (but 4 days before my period) all the symptoms disappeared. I think women should be very careful with soy as there is clearly a hormonal response. The soy powder I used was Alive by Nature's Way with non GMO soy. If I kept it up, who knows about truly serious side effects like breast cancer? Perhaps organic soy wouldn't have produced the same side effects.
Soy protein powder made my temples go bald in two months!! And I had the fullest head of hair and zero family history. It was insane. I'm trashing the rest of it.
