By the sales and lamenting of people you would think 90% of people going to the gym are lactose intolerant.
It's all a scam by the supplement industry, first they tell you soy converts to estrogen to make people buy more expensive whey or casein instead of soy protein, then they tell you about being lactose intolerant to make you buy even more expensive whey isolate....
I have dieted solely on soy protein and soy milk to avoid the bloating from milk sugar, and no problems. Soy makes you look more cut.
Now, I often mix the two, 150ml of milk with 100-150ml of soy milk plus 100ml pineapple juice mixed with 1-2 scoops of ON whey vanilla flavor tastes fucking awesome.
Ditto. I drink soy every day, in moderation, and stay bloody lean.
