How McDonald's UK menu compares to America's - and the items which are more calorific
It's one of the most popular fast food chains on both sides of the Atlantic.
Yet, despite having almost identical menus, food sold at McDonald's in Britain can have drastically different ingredients and nutritional values than their American equivalents.
Here, MailOnline shares how six popular items can vary between the two nations.
The Big Mac
It's the fast food chain's flagship product, loved by millions worldwide.
The Big Mac consists of two beef patties, packed inside a sesame seed bun dressed with lettuce, Big Mac sauce, cheese, pickles and onions.
Despite being made with exactly the same seven components, the burger contains an extra 100 calories in the US. The American version has 590, compared to 493 in the UK.
The difference is the equivalent of treating yourself to a hash brown.
For reference, the daily recommended intake to maintain a healthy weight is 2,000 calories for women and 2,500 for men.
As well as being more calorific, the US burger is packed with more fat (34g vs 24g), saturated fat (11g vs 8.8g) and carbohydrates (46g vs 42g) than the UK version.
