Vani Hari on TBHQ: warns against

Hari has flagged TBHQ (tertiary butylhydroquinone) in her Chick-fil-A campaign and her broader processed-food campaigns as an ingredient she wants removed, per Earth911. Chick-fil-A’s response to her campaign included a commitment to remove TBHQ along with artificial corn syrup and artificial dyes.

Her stated reasoning is consistent with her additive-by-additive approach: TBHQ is a synthetic preservative that she says has no place in food, and major brands can reformulate without it. The Chick-fil-A commitment is her main proof point — a national chain agreeing to drop the ingredient after her pressure.
