I’ve just discovered that these protein bars from Costco contain soy protein isolate (in additin to milk protein and whey protein isolates). Do I need to throw these out? They’re 30gm of protein each, so that’s hard to give up.
Also, if I occasionally have Chinese food or stirfrys with a sause containing soy, am I significantly undercutting my progress?
Is soy to be avoided at all costs? Or is it enough not to use it as a staple in your diet?
