Claim Breakdown
📝 Fact Check: There's no credible evidence that McDonald's all-beef patties in the UK or US contain 30% soy. Official info from McDonald's states their standard beef patties are made from "100% British and Irish beef" with only a pinch of salt and pepper added after cooking—no fillers, soy, or extenders. Food safety and advertising regulations in the UK are strict about ingredient labelling, and independent tests have not found soy as a major ingredient in these burgers. The myth about “30% soy” seems to come from old, debunked internet rumours.
