my 3rd pregnancy was maca filled. i didn't know it wasn't recommended! i loved it, and my 3rd baby was amazing (still is). also had raw cacao a lot during that pregnancy. and kombucha. yeah, i'm bad at stopping what i like just b/c someone thinks it might not be safe.
i think it's the data thing. but that said, those of us who do some of these things don't want to give out data b/c people are already watching us w/ upraised eyebrows!!!
