Vani Hari on dimethylpolysiloxane: warns against

Dimethylpolysiloxane is Hari’s signature U.S.-versus-Europe example. In her 2026 Epoch Times interview, she said McDonald’s U.S. fries contain 11 ingredients including dimethylpolysiloxane — “an ingredient you would find in silly putty” — versus about 3 ingredients in the UK version.

Her stated reasoning is the comparison itself: the same company makes fries with a fraction of the ingredients abroad, which she argues proves the extra U.S. ingredients — including the anti-foaming agent dimethylpolysiloxane — aren’t necessary to make fries. She presents the 11-vs.-3 ingredient count as evidence that U.S. food contains processing chemicals other countries’ versions do without.
