If it's actually "medical consensus", you'd find government agencies or professional organizations calling for bans, at least making announcements that it's harmful.

in response to OP's edit, I'm still not satisfied given that the statement is to call for its GRAS status to be reevaluated, when I specifically mentioned "announcements that it's harmful". At best that's "medical consensus" for "GRAS status should be reevaluated", not "medical consensus is that it absolutely [harmful]".
