McDonalds' food is unhealthy, really unhealthy

Needing a nutritional crutch before embarking on a bout of Christmas elbowing & queuing, I stepped into the futuristic McDonalds @ Oxford Circus, in London.

When I reached the till, I was disturbed to see a sign stating that, "Due to the recent oil depot incident, some products are not available or use substitutes." The incident was the explosion on 11/12/05 at the Buncefield depot in Hertfordshire, 20 miles North of London, which stores petrol, diesel and heating oil and some jet fuel for aircraft.

Now, which of these does McDonalds use & in which items? I think we should be told.
