What’s in that BigMac?

What’s worse? The ingredients or the fact that McDonald’s actually show you what they are on their site. Ok, so the Big Mac itself sounds innocent enough but what is all that stuff in the bun? Fungal enzymes ain’t my idea of added flavour & why do we need an anti-foaming agent in French Fries? Could explain why I last stepped foot in a Macca D’s over 14 years ago.
