Could nutritional yeast cause constipation?

I would look at something else because its nutritional yeast won't constipate. It's just a very small amount of something. There's not enough calories to constipate. I would look at other things that you maybe change in your diet and it could possibly be too much salad or too much greens for some people. Other people, it's not enough greens. So I would look at anything other ordinary that you added to this mix.
